Pin and block universal joints are mechanical couplings that allow for the transmission of torque between two rotating shafts that are not in line with each other. These joints consist of a pin that connects two yokes, or blocks, which are mounted on the shafts. The pin allows for the yokes to rotate independently of each other, yet still transmit torque. Pin and block universal joints are commonly used in automotive applications, such as in the drivetrain to transfer power from the engine to the wheels, as well as in industrial machinery to transmit power between rotating components.

Frequently Asked Questions (FAQs)
1. What are the two types of universal joints?
There are two types of universal joints, defined by their number of bending joints:. Single joint: has only one bending aspect and is capable of operating at up to a 45-degree angle.Double joint: utilizes two bending joints, the double u-joint can operate at angles up to 90 degrees.
2. What are the 3 basic parts of a universal joint?
The universal joint has 3 basic parts, two yokes and a cross. The yokes are connected through a cross as shown. With this arrangement, the output shaft can be turned to a wide range of angles. Now, let's consider different power transmitting scenarios.
3. What is the most common type of universal joint?
A universal joint is a positive, mechanical connection between rotating shafts, which are usually not parallel, but intersecting. They are used to transmIt motion, power, or both. The simplest and most common type is called the Cardan joint or Hooke joint.
4. Can a universal joint work at 90 degrees?
These joints also have mechanical limitations, but in practice they don't turn far (in rear wheel drive applications). In other applications you would not be able to reach 90 degrees because the slave shaft would try to spin bodily rather than about its axis.
5. Why does my universal joint keep breaking?
This usually happens because of corrosion, excessive jolting or vibration, or because the bolts were not properly torqued into place. A worn or cracking transmission or differential housing can also cause this. Of course, u-joint failure isn't limited to these three causes.
