1 Design of Cotter Joint to Connect Piston Rod and Cross head. A cotter joint is used to connect the two shafts which are either subjected to tensile or compressive axial force. DESIGN PROCEDURE OF COTTER JOINT Notations used in design are as follows P Load on the joint or pull acting on rods d Diameter of the rod d1 outer diameter of socketd2 Diameter of spigot or inside diameter of socket d3 Outside diameter of spigot collard4 Diameter of socket collar t1 Thickness of spigot collar a Distance from the.
Design of Gib and Cotter Joint for Strap End of a Connecting Rod. Design of Sleeve and Cotter Joint. Axes of the rods to be joined should be collinear.
Design of the cotter. 3Gib and cotter joints. CAD Model of cotter joint using CATIAV5R20.
Cotter joint is used to connect two rods subjected to axial tensile or compressive loads. Design of the spigot and the Cotter a Crushing strength of the cotter Fd1tσc b Axial stress across the slot of the rod σ 4F πd1 24d 1t STEP 3. The cotter joint is withstanding the load applied during the working condition or not.
There is no relative angular movement between rods. Joints like screwed joint cotter joint sleeve cotter joint universal joint or knuckle joint 1The Knuckle joint is a type of joint which is used in steering system in between the steering rod and pinion of the steering gear as the line of the action axis of both the mechanical parts are intersecting and lies in different planes so it is.
