UNIVERSAL JOINT

Universal Joints are mainly used to create a flexible connections between two rigid shafts at an angle. It permits the transmission of constantly varying power. It is used to connect the propeller shaft with the gearbox shaft to transmit the rotary motion. A universal joint consists of two yokes. These yokes are attached to each end of the shaft. The two yokes are joined by a central or connecting cross piece. The connecting cross piece will turn bearings of the yoke with the change in angularity between shafts.
