This document presents an overview of Hooke's joint, a type of universal joint used for transmitting power between non-parallel shafts that intersect at a line of contact. It describes the joint's applications, including its use in automobiles and machinery, and explains its non-constant velocity nature. Additionally, the document discusses the working principle of Hooke's joints and includes calculations related to single and double Hooke joints.

3. INTRODUCTION
Universal Joint also known as Hooke's Joint is a type
of multifunctional joint which is used to transmit
power between the shafts which are not parallel
but their axes intersect each other at a line of
contact, further the axes of the shafts are slightly
inclined with each other for easy transmission of
power.
The main point to note here is that it's difference
being it's a non constant velocity joint i.e. the
driving shaft moves at constant angular velocity
and the driven at varying.

4. HOOKE’S JOINT
As Hooke's Joint is a type of multifunctional joint which is used to transmit power between
the shafts which are not parallel but their axes intersect each other at a line of contact,
further the axes of the shafts are slightly inclined with each other for easy transmission of
power..

Mainly it's used to transmit power from gear box to the rear axle in automobiles.
Other applications include use in Stone crushers, Centrifugal blowers, Belt
conveyors, etc.

Universal joints allow drive shafts to move up and down with the suspension while the
shaft is moving so power can be transmitted when the drive shaft isn't in a straight line
between the transmission and drive wheels. Rear-wheel-drive vehicles have universal
joints (or U-joints) at both ends of the drive shaft.

DRIVING AND DRIVEN SHAFTS

9. Double Hooke Joint
These were the calculations related to single
Hooke's Joint.Now there is another type of
Hooke's Joint named as DOUBLE HOOKE'S
JOINT Objective of which is to maintain
constant velocity ratio.
