What is function of cotter joint?
The function of cotter in cotter joint is to connect rigidly two rods which transmit motion or force without rotation.
What is a GIB joint?
3 Gib and Cotter joint. Moreover, gibs provide a larger bearing surface for the cotter to slide on, due to the increased holding power. Thus, the tendency of cotter to slacken back owing to friction is considerably decreased. The jib, also, enables parallel holes to be used.
What is socket and spigot joint?
A cotter joint, also known as a socket and spigot joint, is a method of temporarily joining two coaxial rods. One rod is fitted with a spigot, which fits inside a socket on one end of the other rod. Slots in the socket and the spigot align so that a cotter can be inserted to lock the two rods together.
What is a gib in machine design?
1. (gĭb) A plain or notched, often wedge-shaped piece of wood or metal designed to hold parts of a machine or structure in place or provide a bearing surface, usually adjusted by a screw or key.
What is bell and spigot joint?
A form of joint used on pipes that have an enlarged diameter or bell at one end and a spigot at the other that fits into and is laid in the bell. The joint is then made tight by lead, cement, rubber O-ring, or other jointing compounds or materials.
What type of joint is a knuckle joint?
pin joint
A knuckle joint is a form of pin joint that’s used to transmit tension loads while allowing rotation in one plane. A knuckle joint is a type of pin joint used to join two components that are loaded in tension.
What is Gib in mechanical engineering?
(ɡɪb) n. (Mechanical Engineering) a metal wedge, pad, or thrust bearing, esp a brass plate let into a steam engine crosshead.
What is a spigot in engineering?
General Engineering) a short cylindrical projection on one component designed to fit into a hole on another, esp the male part of a joint (spigot and socket joint) between two pipes.
What is class 6 ball and socket joint?
(a) Ball and socket joint is a movable joint. In this a bone with round head fits into hollow space of another bone. This makes the bone to rotate freely. For example, bones of hip and shoulder can move in all directions due to ball and socket joints.
What is the difference between a gib and a cotter?
Gib and cotter joints are used for rods of square or rectangular cross-section. The end of one rod fits the end of the other rod which made in the form of a strap. A gib used along with the cotter to make this joints. Gib is likely a cotter but with two gib heads at its ends. Whit the thickness of the gib and cotter are same.
What is a cotter joint assembly?
The Cotter joint assembly consists of the three components: Spigot: It is the male part of the joint, it has a rectangular slot for passing the cotter through it. The spigot has a collar that rests against the socket end. Socket: It is the female part of the joint, it also has a rectangular slot for passing the cotter through it.
Why are cotter joints used in rotating shafts?
Cotter joints are used to support axial loads between the two rods, tensile or compressive. Although a cotter joint will resist the rotation of one rod relative to the other, it should not be used to join rotating shafts. This is because the cotter will not be balanced and may work loose under the combination of vibration and centrifugal force.
What are the advantages of a jib Cotter?
Moreover, gibs provide a larger bearing surface for the cotter to slide on, due to the increased holding power. Thus, the tendency of cotter to slacken back owing to friction is considerably decreased. The jib, also, enables parallel holes to be used.
