ZLZ type connecting intermediate shaft elastic pin gear coupling (GB5015-2003)
●The elastic pin gear coupling is a pin made of several non-metallic materials, placed in the mating hole between the two halves of the coupling and the inner surface of the outer ring, and the two halves are transmitted through the pin. The coupling is connected with the following characteristics: (1) The elastic pin gear coupling transmits large torque, and the rotation diameter is mostly smaller than that of the gear coupling at the same torque, with a smaller volume and a smaller mass. It is light and can partially replace gear couplings. (2) Compared with gear couplings, it has a simple structure, fewer components, and is more convenient to manufacture. It does not require gear processing machine tools. (3) The elastic pin gear coupling is easy to maintain and has a long service life. The nylon pin can be replaced by removing the baffle. (4) Nylon pin of elastic pin tooth coupling is self-lubricating material and does not need lubrication, which not only saves lubricating oil but also purifies the working environment. (5) The elastic pin gear coupling has poor vibration reduction performance 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.
