Universal Joint

Universal joint is also called the U-joint. This type of joint is used to connect the rods whose axes are inclined at some angle with each other. The hinges that are joined with each other have an angle of 90° between each other. The typical applications of these universal joints are in the control mechanism, instrumentation, radio, aircraft, textile machinery, etc. The construction of this joint has two yokes one on each of the shaft and the cross shaped part called as spider. This spider in the universal joint is important as it connects both the shafts and effectively transfers the torque.
