LZJ (formerly ZLZ) type connecting intermediate shaft elastic pin gear coupling
Summary:ZLZ type elastic pin gear coupling is a pin made of several non-metallic materials, which is placed in the mating hole between the two halves of the coupling and the inner surface of the outer ring. Half coupling connection.
Main features of ZLZ type elastic pin gear coupling:
ZLZ-type 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, through the pin to transmit torque to achieve two For semi-coupling connection, the ZLZ elastic pin gear coupling has the following characteristics:
(1) ZLZ-type elastic pin gear couplings transmit large torque. At the same torque, the rotation diameter is mostly smaller than that of gear couplings, with small volume and light weight, which 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 machines.
(3) The ZLZ elastic pin gear coupling is convenient for maintenance and has a long service life. The nylon pin can be replaced by removing the baffle.
(4) The nylon pin of the ZLZ elastic pin gear coupling is a self-lubricating material and does not need lubrication, which not only saves lubricating oil, but also purifies the working environment.
(5) ZLZ type elastic pin gear coupling has poor vibration reduction performance and high noise.
ZLZ type 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.
