Cotter joint is used to connect tworods subjected to axial tensile or compressive loads. Cotterjoint is widely used to connect the piston rod and cross head ofthe steam engine, so as a joint between the piston rod and thetailor pump rod, foundation bolt etc. Failure of cotter jointmay causes accident, so it is necessary to design cotter joint towithstand under tension without failure the effective design ofmechanical device or assembly demand the predictiveknowledge of its behavior in working condition. In this projectwe use theoretical method for finding dimensions of cotterjoint. After the design of cotter joint, The modeling of cotterjoint is done by using 3D software. Here we will be usingCATIA V5R19 for modeling. After modeling on CATIA, wewill analyze cotter joint on software named as “ANSYS V15”.Keywords— Cotter joint, Design, Modeling, Analysi ,CATIAV5R20, ANSYS R15.1. INTRODUCTIONThe Failure of cotter joint may causes accident so it isnecessary to design cotter joint to withstand under tensionwithout failure. The effective design of mechanical deviceor assembly demand the predictive knowledge of itsbehavior in working condition. It became necessary for thedesigner to know the forces and stress developed during itsoperation. In this project we use theoretical method forfinding dimensions of cotter joint. After the design of cotterjoint, the modeling of cotter joint is done by using CATIAV5R20. Here we will be using CATIA V5R19 formodeling. After modeling on CATIA V5R19, We willanalyze cotter joint on software named as “ANSYS V15”.A cotter is a flat wedge shaped piece of rectangularcross-section and its width is tapered (Either on one side orboth sides) from one end to another for an easy adjustment.The taper varies from 1 in 48 to 1 in 24 and it may beincreased up to 1 in 8, If a locking device is provided. Thelocking device may be a taper pin or a set screw used onthe lower end of the cotter. The cotter is usually made ofmild steel or wrought iron. A cotter joint is a temporaryfastening and is used to connect rigidly two co-axial rods orbars which are subjected to axial tensile or compressiveforces. It is usually used in connecting a piston rod to thecross- head of a reciprocating steam engine, A piston rodand its extension as a tail or pump rod, Strap end ofconnecting rod etc. [6]IJERTV6IS070202Fig 1: Cotter joint2. LITURATURE SURVEYShaikh J, vanka H, “Modeling and analysis ofknuckle joint”, International journal & magazine ofengineering. They have completed Modeling and analysisby using advanced modeling software system CATIA andANSYS respectively. The knuckle joint is a type of jointwhich is used in steering system in between steering rodand steering gear. In this joint is employed here in order toget the maximum productivity and manufacturingtechnology must not be stiff. FMS (Flexible ManufacturingSystem) is used in order to gain the advantage over simplemanufacturing of knuckle joint. Final dimension fromtheoretical calculation of knuckle joint. Model of knucklejoint is made in CATIA V5 and that model is taken toANSYS and stimulated with various material and check forbest material which suit for given design load. From resultTeflon is best material for design and it close to stress gotfrom stainless steel and cast iron with less manufacturingcost.

4. If the cotter pin has a self-spreader mechanism, remove the spreader before attempting cotter pin removal. 5. Place the tail of the cotter pin removal tool into the cotter pin to be removed. The tail should be seated in the pin as far as possible (Figure 3). FIGURE 3 6. Apply forward pressure to the pneumatic hammer w hile pulling the trigger.

According to a joint announcement issued by O.W. Ahl, president of Hibbard, Spencer, Bartlett and Co. and John M. Cotter, president of Cotter & Co.,
Metric DIN 94 Split Pins (Cotter Pins) are common used fasteners that hold assemblies together. Made of soft metal wire looped on itself so the two resulting tines can be inserted into a pre-drilled hole and bent to keep it in place. Cotter pins are typically made
cotter pins around connecting pins for proper clearance. 2. Align holes in lower gear assembly with rear holes in the push assembly. Insert 1" x 3-5/16" clevis pins through ears, from the outside to the inside of the headgear. Secure with two 1/4" x 1-1/2" cotter pins.

rotational motion and astrophysics can have impacts on our lives, as well on the environment/society. This application and development of skills can be achieved using a variety of approaches, including investigation and problem solving. The Unit will cover the key areas of kinematic relationships, angular motion, rotational dynamics, gravitation, general relativity, and stellar physics .
