The three-jaw coupling for pumps uses several pins made of non-metallic materials, which are placed in the mating holes between the two halves of the coupling and the inner surface of the outer ring, and the two halves of the coupling are realized by transmitting torque through the pins. The coupling has the following characteristics: (1) The transmission torque is large, the rotating diameter is mostly smaller than the gear coupling at the same torque, the volume is small, and the weight is light. It can partially replace the gear coupling .
SWP-E type cross shaft universal joint is used to connect two shafts (active shaft and driven shaft) in different mechanisms to make them rotate together to transmit torque mechanical parts.In high-speed and heavy-duty power transmission, some couplings also have the function of buffering, damping and improving the dynamic performance of the shafting.
The universal coupling utilizes the characteristics of its mechanism to make the two shafts not on the same axis, and when there is an angle between the axes, it can realize the continuous rotation of the connected two shafts and transmit torque and motion simultaneously.The characteristics of the universal coupling are: its structure has a large angular compensation capability, a compact structure, and a transmission.

Due to reasons such as manufacturing, installation, load deformation and temperature changes, it is difficult to maintain strict alignment of the two shafts after installation and adjustment.Existence degree of displacement in x and Y directions and skew angle CI.When the radial displacement is large, you can choose a slider coupling, and when the angular displacement is large or the connection of two intersecting shafts, you can choose a universal coupling.When the two shafts produce a large additional relative displacement during the working process, a flexible coupling should be used.
