PERSONAL ENGINEERING ACTIVITY

As a mechanical engineer, before undertaking any task I checked the feasibility of the project. In this project, my role is as team . This report provides an insight into the design and fabrication of a QUICK LIFTING JACK. I wanted to know more details of the project before commencing; hence, I researched the topic thoroughly by referring to journals and articles online. Additionally, I obtained more information by taking references about the topic.

ABSTRACT

This project work titled “FABRICATION OF QUICK LIFTING JACK WITH GEAR ARRANGEMENT” has been conceived having studied the difficulty in lifting the any type of light vehicles. Our survey in the regard in several automobile garages, revealed the facts that mostly some difficult methods were adopted in lifting the vehicles for reconditioning. Now the project has mainly concentrated on this difficulty, and hence a suitable device has been designed. Such that the vehicle can be lifted from the floor land without application of any impact force. The fabrication part of it has been considered with almost case for its simplicity and economy, such that this can be accommodated as one of the essential tools on automobile garages.

INTRODUCTION

This device the quick lifting jack with gear arrangement for automobile garages has been developed to later the needs of small and medium automobile garages, who are normally man powered with very minimum of skilled labors. In most of the garages the vehicles are lifted by using screw jack. This needs high man power and skilled labors. In order to avoid all such disadvantages. This, motorized hydraulic jack has been designed in such a way that it can be used to lift the vehicle very smoothly without any impact force. The operation is made be simple that

12 | P a g e

even an unskilled labor can handled, by just demonstrating the working of the motorized hydraulic jack once.

LITERATUE REVIEW

13 | P a g e

In the accompanying drawings, Figure 1 is a vertical sectional elevation of the angles to Fig. 1. 14 | P a g e

In the main, the two" constructions are substantially alike, but a material difference appears particularly in connection withtlie means for engaging the gears and holding the same as against a reverse movement of the handle or lever and also for holding the screw in the standard except when it is purposely lifted up or out, as will presently appear. In detail, the parts comprise a standard A Y which has longitudinal channels or grooves '2 inside, and a screw B with a pin a through its lower end having its ends engaged in said grooves and serving to guide the screw on 'straight lines vertically but preventing end rotation in the standard, as formerly. There are also two miter gears C and D, the gear C being internally threaded and mounted upon the screw B, and the said screw and gear adapted to be raised within the standard to any desired elevation or to be lifted bodily off and out if desired. Ordinarily, in use, when the ,jack is brought to a vehicle to apply it to the axle, a quick' adjustment of the parts is made by lifting the screw with gear C bodily up to about the elevation wanted and the gear is then run down and seated in operating position on the standard in mesh with the gear D. This affords a quick and easy adjustment to an axle rather than awaiting the slow method of jacking up the screw by or through the lever H. Gear G rests directly upon the top of the standard, which serves as a bearing therefore, and the gear D is ed upon. a short spindle or shaft E, shown as removably secured into the upper elevation at right other important function. End of the standard and having the handle H rotatably mounted 15 | P a g e

the reon outside of the pawl and ratchet teeth and the jack is .raised or lowered according as the pawl is set to work at one end or the other. As to these features, it need only' be said that they are acknowledged to be present in my patent above referred .to, but a present description thereof is' deemed necessary in order that the associated novelty in this case may be understood.

In the said patent means are provided for frictionally locking the gears and holding them in any position to which they may be hold, as for example, when the jack is being raised. Then the handle is raised as far as may be convenient and depressed to do the lifting. However, if the jack be without a load, the tendency is for the gears to work too easy and they will run back with the direction of the' handle and no real progress is made in jacking up the screw. To prevent this result I employed a split ring or spring L in my said patent, which was mounted on shaft E and. bore against the hub of gear D and served the purpose of holding said gear 1 firmly enough to prevent backward rotation when the lever was making its idle or reverse stroke,-but I found that I could perform this function as well by an arrangement of spring which would enable it to perform still an To this end I have provided the jack with a substantially flat spring L which has its lower end affixed to the standard A at a on the opposite side from gear D and its 'free end' projecting upward and reversely turned with something turned by the lever pending the moment when the lever is reversed to get another of a shoulder or tooth shaped 16 | P a g e

projection 72 formed by bending the said spring rather sharply at said point and adapting the said bent portion 1) to bear against the hub of gear C with . Sufficient tension or pressure to frictionally hold the said gear. and prevent backward rotation when the handle is making its idle stroke in order to get a grip. This construction and arrangement of the spring serves identically the same purpose as the spring L in the-patent aforesaid, but has the further advantage and value of holding the gear C u on the 'standard A when other- Wise it woul fall out. It has already been observed that the screw and gear 0 can be bodily withdrawn from the standard, and which was the case also in the above patent, but I have found that entire freedom in this respect is not desirable and that it were better to have a temporary connection so that ordinarily the parts will be held together, but can be separated at will. To this end, the hub of gear C is provided with an annular shoulder or groove 9 which produces a shoulder, and in or upon which the tooth like projection b of spring L engages. and serves to lock the said gear with the standard temporarily as against its being drawn OE, and a ard 9 corners the spring in said groove. 4 or rather hook shaped extreme it y of the spring with the finger the parts may be readily disengaged when it is desired to withdraw the gear and screw. Thus the said spring performs two important functions by reason of up by engaging the curve seas-

7e this arrangement, and a material improvement of the jack is obtained. What I claim is: v In a lifting jack, a standard and a lift screw mounted thereon and adapted to be bodily raised in respect thereto, .a nut member for said screw adapted to rest upon said standard and to be lifted apart there for quick adjustment of the nut member upon said screw, means on said standard separably engaged with said nut member to cerate the same in a given direction, and a friction device form nut member to prevent back rotation thereof upon idle movements of said operating means, said device and nut member having self-separable 'engaging portions to permit-the screw to be lifted by one hand while adjustment of the nut member may be had by the other hand.

GEARS

Bevel gears are gears where the axes of the two shafts intersect and the tooth-bearing faces of the gears themselves are conically shaped. Bevel gears are most often mounted on shafts that are 90 degrees apart, but can be designed to work at other angles as well. The pitch surface of bevel gears is a cone. 20 | P a g e

Two important concepts in gearing are pitch surface and pitch angle. The pitch surface of a gear is the imaginary toothless surface that you would have by averaging out the peaks and valleys of the individual teeth. The pitch surface of an ordinary gear is the shape of a cylinder. The pitch angle of a gear is the angle between the face of the pitch surface and the axis. The most familiar kinds of bevel gears have pitch angles of less than 90 degrees and therefore are cone-shaped. This type of bevel gear is called external because the gear teeth point outward. The pitch surfaces of meshed external bevel gears are coaxial with the gear shafts; the apexes of the two surfaces are at the point of intersection of the shaft axes. Bevel gears that have pitch angles of greater than ninety degrees have teeth that point inward and are called internal bevel gears. Bevel gears that have pitch angles of exactly 90 degrees have teeth that point outward parallel with the axis and resemble the points on a crown. That's why this type of bevel gear is called a crown gear.

Frame: Frame is carries an all part’s of the machine, It is made up of mild steel.

22 | P a g e

Handle: A handle is a part of, or attachment to, an object that can be moved or used by hand. 23 | P a g e

Bearing: A bearing is machine element which s another moving machine element. The moving machine element 24 | P a g e

is known as journal. Bearing permits a relative motion between the surfaces of the , while carrying the load. A certain amount of power is wasted in overcoming frictional resistance. In order to reduce frictional resistance and wear and to carry away the heat generated, lubricant may be provided. The lubricant used is usually a mineral oil refined from petroleum. The bearing block is used to hold the bearings. It is made up of cast iron. All the bearings are fitted on the machine frame. A bearing is machine element which s another moving machine element.

Bolt: 25 | P a g e

A screw, or bolt, is a type of fastener, typically made of metal, and characterized by a helical ridge, known as a male thread (external thread) or just thread, wrapped around a cylinder. Some screw threads are designed to mate with a complementary thread, known as a female thread (internal thread), often in the form of a nut or an object that has the internal thread formed into it. Other screw threads are designed to cut a helical groove in a softer material as the screw is inserted. The most common uses of screws are to hold objects together and to position objects. A screw will almost always have a head on one end which contains a specially formed shape that allows it to be turned, or driven, with a tool. Common tools for driving screws include screwdrivers and wrenches. The head is usually larger than the body of the screw, which keeps the screw from being driven deeper than the length of the screw and to provide a bearing surface. There are exceptions; for instance, carriage bolts have a domed head that is not designed to be driven; set screws often have a head smaller than the outer diameter of the screw; J-bolts have a J-shaped head which is not designed to be driven, but rather is usually sunk into concrete 26 | P a g e

allowing it to be used as an anchor bolt. The cylindrical portion of the screw from the underside of the head to the tip is known as the shank; it may be fully threaded or partially threaded.[1] The distance between each thread is called the "pitch". The majority of screws are tightened by clockwise rotation, which is termed a right-hand thread; a common mnemonic device for ing this when working with screws or bolts is "righty-tighty, lefty-loosey." Screws with left-hand threads are used in exceptional cases. For example,

when

the

screw

will

be

to

counterclockwise torque (which would work to undo a right-hand thread), a left-hand-threaded screw would be an appropriate choice. The left side pedal of a bicycle has a left-hand thread. More generally, screw may mean any helical device, such as a clamp, a micrometer, a ship's propeller or an Archimedes' screw water pump.

MANUFACTURING PROCESS PIPE CUTTING: Pipe cutting, or pipe profiling, is a mechanized industrial process that removes material from pipe or tube to create a desired profile. Typical profiles include straight cuts, mitres, saddles and midsection holes.

28 | P a g e

WELDING:Welding is a fabrication or sculptural process that s materials, usually metals or thermoplastics, by causing fusion, which is distinct from lower temperature metaling techniques such as brazing and soldering, which do not melt the base metal. In addition to melting the base metal, a filler material is often added to the t to form a pool of molten material (the weld pool) that cools to form a t that can be as strong, or even stronger, than the base material. Pressure may also be used in conjunction with heat, or by itself, to produce a weld. Although less common, there are also solid state welding processes such as friction welding or shielded active gas welding in which metal does not melt. Some of the best known welding methods include:  Shielded metal arc welding (SMAW) - also known as "stick welding or electric welding", uses an electrode that has flux around it to protect the weld puddle. The electrode holder holds the electrode as it slowly melts away. Slag protects the weld puddle from atmospheric contamination. 29 | P a g e

 Gas tungsten arc welding (GTAW) - also known as TIG (tungsten,

inert

gas),

uses

a

non-consumable

tungsten electrode to produce the weld. The weld area is protected from atmospheric contamination by an inert shielding gas such as argon or helium.  Gas metal arc welding (GMAW) - commonly termed MIG (metal, inert gas), uses a wire feeding gun that feeds wire at an adjustable speed and flows an argon-based shielding gas or a mix of argon and carbon dioxide (CO2) over the weld puddle to protect it from atmospheric contamination.  Flux-cored arc welding (FCAW) - almost identical to MIG welding except it uses a special tubular wire filled with flux; it can be used with or without shielding gas, depending on the filler.  Submerged

between 1 inch (25 mm) and 12 inches (300 mm) in a vertical or close to vertical position. Many different energy sources can be used for welding, including a gas flame, an electric arc, a laser, an electron beam, friction, and ultrasound. While often an industrial process, welding may be performed in many different environments, including in open air, under water, and in outer space. Welding is a hazardous undertaking and precautions are required to avoid burns, electric shock, vision damage, inhalation of poisonous gases and fumes, and exposure to intense ultraviolet radiation. Until the end of the 19th century, the only welding process was forge welding, which blacksmiths had used for centuries to iron and steel by heating and hammering. Arc welding and oxyfuel welding were among the first processes to develop late in the century, and electric resistance welding followed soon after. Welding technology advanced quickly during the early 20th century as the world wars drove the demand for reliable and inexpensive ing methods. Following the wars, several modern welding techniques were developed, including manual methods like SMAW, now one of the most popular welding methods, as well as semi-automatic 31 | P a g e

and automatic processes such as GMAW, SAW, FCAW and ESW. Developments continued with the invention of laser beam welding, electron beam welding, magnetic pulse welding (MPW), and friction stir welding in the latter half of the century. Today, the science continues to advance. Robot welding is commonplace in industrial settings, and researchers continue to develop new welding methods and gain greater understanding of weld quality.

WORKING PRINCIPLE The quick lift jack is a device used for lifting heavy loads by the application of much smaller force. The working principle of a quick lift jack may be explained with the help of Fig. Consider a two bevel gears arrangement.

32 | P a g e

Quick lift jacks and much other technological advancement such as automobile brakes and dental chairs work. Handle is used to rotates the bevel gear arrangements. Jack arrangement i.e. lifting rod will be fixed to bevel gear. Clockwise rotation of handle, jack will rotates upward motion and anti clockwise rotation of handle, jack will rotates downward motion.
