LZJ (formerly ZLZ) type connecting intermediate shaft elastic pin gear coupling

Detailed parameters of LZJ (formerly ZLZ) type intermediate shaft elastic pin gear coupling

LZJ (formerly ZLZ) type intermediate shaft elastic pin gear coupling has a large transmission torque. At the same torque, the rotation diameter is mostly smaller than that of the gear coupling. It is small in size and light in weight. It can partially replace the gear coupling. Coupling: Compared with gear couplings, it has simple structure, fewer components, convenient manufacturing, no gear processing machine tool; convenient maintenance, longer life, and nylon pin can be replaced by removing the baffle.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.The disadvantages of elastic pin gear couplings are poor vibration reduction and high noise.Although it has the performance of compensating the relative deviation of the two shafts, it is only suitable for medium and high power transmission, and is not suitable for working parts that have certain requirements for vibration reduction and strict noise control.
