Types of Gear Couplings In order to understand different types of gear couplings, we need to first understand what exactly is a gear coupling. Let us first learn what is a coupling. A coupling can be termed as a power transmitter in simplest terms. They act as a connecting component between two shafts. The difference in the coupling collection is actually decided by the complexity of connectivity, the power that needs to be transferred, and the operation field. Gear couplings are one such type of couplings which can relay extreme high torques. Where are Gear Couplings used? Gear couplings are used in high torque high power applications. This is because they can tolerate more torque than any other universal joint. However, another difference between the gear coupling and a universal joint is that universal joints produce lesser vibration. In contrast, gear couplings are made of two hubs with internal teeth, external teeth and a single piece or two-piece sleeve. What are the diffe...
