Detailed parameters of LZ (formerly ZL) type elastic pin gear coupling

 

The base moment of the ZL-type elastic pin gear coupling realizes the connection of the two halves of the coupling. The coupling has the following characteristics:
(1) The transmission torque is large. At the same torque, the rotation diameter is mostly smaller than that of the gear coupling, and the volume is lighter. It can partially replace the gear coupling.
(2) Compared with gear couplings, it has simple structure, fewer components, and is more convenient to manufacture. It does not require gear processing machine tools.
(3) Convenient maintenance and long service life. The nylon pin can be replaced by removing the baffle plate.
(4) The nylon pin is a self-lubricating material and does not need lubrication, which not only saves lubricating oil, but also purifies the working environment.
(5) Poor vibration reduction and high noise.
The elastic pin gear coupling has the performance of compensating the relative deviation of the two shafts to a certain extent. It is suitable for medium and high power transmission, and is not suitable for working parts that have certain requirements for vibration reduction and strict control of noise.
