Types of Cotter Joints

Types of Cotter Joints Points : Types of Cotter Joints, Socket and spigot cotter joint, Sleeve and cotter joint, Gib and cotter joint Three generally use cotter joints to connect two rods through a cotter:
1. Socket and spigot cotter joint
2. Sleeve and cotter joint
3. Gib and cotter joint 1. Socket and Spigot Cotter Joint Socket and spigot cotter joint, one end of rods is give by a socket kind of end and other end of other rod is inserting into a socket. End of rod which goes into a socket is too call spigot. Rectangular hole is prepared in socket with spigot. Cotter is then motivated firmly during a hole in order to create passing connection among two rods. Load is generally acting axially, but it change its way with thus cotter joint have to be intended to carry equally tensile and compressive loads. Compressive load is taken up by the collar on spigot. 2. Sleeve and Cotter Joint Sleeve and cotter joint is use to attach two round rods or bars. In this kind of joint, sleeve or muff is use above two rods with then two cotters are inserting in holes give for them in sleeve with rods. Taper of cotter is generally 1 in 24. It might be renowned that taper sides of the two cotters must face each other. Clearance is so adjusted that while cotters are driven in, two rods come closer to each other hence make joint tight. 3. Gib and Cotter Joint Gib and cotter joint is generally use in strap end of a connecting rod. In such cases, while cotter alone is motivated, the friction among its ends with inside of the slots in strap tends to reason sides of strap to spring open outwards. In order to stop this, gibs are use which holds jointly ends of strap. also, gibs give a larger bearing surface for cotter to slide on, owing to enlarged holding power. Therefore, tendency of cotter to slacken back owing to friction is greatly decrease. Jib, also, enable parallel holes to be use.
