Plum coupling, diaphragm coupling, elastic pin coupling, drum gear coupling_Hangzhou Hengli Transmission Machinery Co., Ltd.

Elastic pin couplings are generally elastic pin couplings and nylon rod pin couplings. The former is connected by several screws, and the nut end of the screw is equipped with an elastic washer.The latter uses nylon rods. The two half-sections are drilled as large as holes, and the nylon rods are inserted. The outside is covered with a baffle and a pin coupling. To put it simply, the pin coupling is to connect two holes. The half couplings are connected by N nylon rods.Can play a role in compensation

Couplings are also called couplings.A mechanical component used to firmly connect the driving shaft and the driven shaft in different mechanisms to rotate together and transmit motion and torque.Sometimes it is also used to connect shafts and other parts (such as gears, pulleys, etc.).It is often composed of two halves, which are connected by a key or tight fit, respectively, and fastened to the ends of the two shafts, and then the two halves are connected in some way.The coupling can also compensate for the offset between the two shafts due to inaccurate manufacturing and installation, deformation or thermal expansion during work, etc. (including axial offset, radial offset, etc.)

When selecting a coupling, whether the shaft hole has a counterbore or not depends mainly on whether the shaft can have axial movement, whether axial tension or installation space is required.

There are five types of coupling fixing methods: fastening bolt type, clamping type, separation type, semi-separation type and keyway type.

Due to reasons such as manufacturing, installation, load deformation and temperature change of the coupling, it is difficult to keep the two shafts strictly aligned after installation and adjustment.
