1. Universal Joints

Tekanpur, Gwalior.

2. What is a Universal Joint? What is it’s purpose?
 A universal joint is a joint or coupling in a rigid rod
that allows the rod to 'bend' in any direction.
 The purpose of a universal joint is to transfer
torque from one plane to another, retaining
whatever rotational energy applied to the shaft.

3. Types of Universal Joints
 Cross Type or Two Yoke Type.
 Ball And Trunnion Type.
 Constant Velocity Type.

4. Ball And Trunnion Type. Constant Velocity Type.

5. Design/Structure
 A universal joint uses basic mechanical principles,
there are four points of attachment (usually with
needle bearings), two per shaft.
 Each of these shaft ends (called yoke arms or yoke
ends) attaches to a cross piece, providing a flexible
joint which can take large loads.

6. Features and Functions
 As mentioned earlier the whole concept of a
universal joint is to provide a mechanical means
for transmitting torque and rotation.
 The Universal joint only suffers from one major
problem: even when the input drive shaft axle
rotates at a constant speed, the output drive shaft
axle rotates at a varying speed.

7. Materials Used
 Universal joints can be made out of almost any
material depending on the application.
 Steel, cast iron, brass or even plastic.
 Cost can effect the materials.
