What is cotter joint and uses?
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 the function of cotter?
FUNCTION- A cotter joint is used to connect one end of a rod is provided with a socket type of end and the other end of the rod is inserted to a socket. The end of the rod which goes into a socket is also called Spigot. . Joints between the piston rod and the cross need of the steam engine.
What is cotter and knuckle joint?
COTTER AND KNUCKLE JOINTS It is usually used in connecting a position rods to the cross head of a reciprocating steam engine, strap end of connecting rod etc.
What is the function of cotter in cotter joint where it is used?
The function of cotter in cotter joint is to connect rigidly two rods which transmit motion or force without rotation.
Which material is used for cotter joint?
The material selected for cotter joint is plain carbon steel of Grade 30C8 which is having (Syt=400N/mm2), so that cotter joint will fail above (Syt=400N/mm2). By the calculation, we found that maximum force applied is 50KN.
What does a cotter joint transmit?
Cotter joint is used to transmit Concept: A cotter is a flat wedge-shaped piece of steel. This is used to connect rigidly two rods that transmit motion in the axial direction, without rotation. These joints may be subjected to tensile or compressive forces along the axes of the rods.
What is sleeve and cotter joint?
1. Sometimes, a sleeve and cotter joint as shown in Fig. 1 and 2, is used to connect two round rods or bars. In this type of joint, a sleeve or muff is used over the two rods and then two cotters (one on each rod end) are inserted in the holes provided for them in the sleeve and rods.
What is a cotter joint used for in an engine?
In an automobile engine, the cotter joint is used to connect the extension of the piston rod with the connecting rod in the crosshead. The Kottar joint has historically been used to connect connecting rods to steam engines and pumps of dumping mines. It is used in bicycles to connect the paddle to the sprocket wheel.
Is there any relative angular movement between rods in Cotter joint?
There is no relative angular movement between rods. Cotter joint is widely used to connect the piston rod and crosshead of a steam engine, as a joint between the piston rod and the tailor pump rod, foundation bolt etc. Cotter Joint has mainly three components – spigot, socket and cotter as shown in Figure 9.1.
What is a cotter joint for coaxial cable?
A cotter joint, also known as a spigot and socket joint, is a method of temporarily connecting two coaxial rods. A rod is fitted with a spigot, which fits inside a socket at one end of the other rod. The slots in the socket and spigot align so that a cotter can be inserted to close both rods together.
What are the parts of a cotter?
3) cotter : is a wedge shaped piece of metal which actually connects two parts which are non rotating. 2) connection of the piston rod to cross head of a reciprocating steam engine. 3) valve rod & its stem 4) piston rod to the trail end in an air pump. 5) Cycle pedal sprocket wheel.
