Detailed parameters of LZD (formerly ZLD) conical shaft hole elastic pin gear coupling
　　The ZLD type conical shaft hole elastic pin gear coupling has a certain performance of compensating the relative deviation of the two shafts. It is suitable for medium and large power transmissions. It is not suitable for those with certain requirements for vibration reduction and strict control of noise. Working position.
　　ZLD type conical shaft hole elastic pin gear coupling is a pin made of a number of non-metallic materials, placed in the mating hole between the two halves of the coupling and the inner surface of the outer ring, and is transmitted by the pin Torque realizes the coupling 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.
