What is sleeve in cotter joint?
Sleeve and cotter joint is a type of joint use that usually connects two identical coaxial cylindrical rods. It includes one sleeve and two wedge-shaped tapered coaters. Suitable slots cut into sleeves and cylindrical rods.
What are the steps involved in sleeve and cotter joint design procedure?
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. The taper of cotter is usually 1 in 24.
How do you make a cotter?
DESIGN PROCEDURE FOR COTTER JOINTS
- Calculate the diameter of the each rod by :
- Calculate the diameter d2 of the spigot on the basis of tensile stress.
- Calculate the outside diameter d1 of the socket on the basis of tensile stress in the socket from the equation :
What is draw of cotter joint?
AIM- Design and drawing of Cotter Joint. 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.
What formula is cotter width?
Explanation: Cotter is subjected to double shear hence width=P/(2*τ*t). Explanation: Compressive stress= P/ [(socket dia-spigot dia)*thickness].
What is the function of cotter?
A cotter is a pin or wedge passing through a hole to fix parts tightly together. In British usage cotter pin has the same meaning, but in the U.S. it means a split pin. Typical applications are in fixing a crank to its crankshaft, as in a bicycle, and a piston rod to a crosshead, as in a steam engine.
What is cotter joint in machine design?
Ans: Cotter is a flat wedge shaped part which is used to connect two rods which transmit the force/motion but without rotation. Cotter is fitted in the tapered slot and remains in its position by wedge action. ii) It ensures tightness of the joint in operation & prevents loosening of the parts.
What is product drawing?
Product sketching or Object drawing is essential for the representation of 3D objects. It is a 2D representation of a 3D object or objects for the purpose of communication of a designer’s visualization.
Where is cotter joint used?
Cotter joint is used to connect two rods subjected to axial tensile or compressive loads. Cotter joint is widely used to connect the piston rod and cross head of the steam engine, so as a joint between the piston rod and the tailor pump rod, foundation bolt etc.
