There are many types of couplings. According to whether or not they contain elastic elements inside, they can be divided into rigid couplings and flexible couplings.
The pin coupling uses a pin with an elastic sleeve (rubber material) at one end and is installed in the flange holes of the two coupling halves to connect the two coupling halves.
Flange Coupling uses bolts to connect two flange (flange) disk half couplings. The two coupling halves are keyed to the two shafts to achieve two-axis coupling to transmit torque and movement.
The universal joint is a machine that realizes variable-angle power transmission and is used to change the position of the transmission axis. It is the “joint” component of the universal transmission of the automotive drive system.
The plum coupling is a common coupling, also known as a claw coupling, consisting of two metal jaws and an elastomer. The two metal claw plates are generally No. 45 steel, but they also have aluminum alloys where the required load is sensitive.
