LZD type (formerly ZLD type)Elastic pin with conical shaft holeGear coupling(GB5015-2003)
ZLD type conical shaft hole elastic pin tooth typeCouplingIt uses several pins made of non-metallic materials and is placed in the mating hole between the two halves of the coupling and the inner surface of the outer ring, and the two halves of the coupling are connected through the pin to transmit torque. 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 a simple structure, fewer components, and is more convenient to manufacture. It does not require gear processing machines.
(3) Convenient maintenance and long service life. The nylon pin can be replaced by removing the baffle.
(4) The nylon pin is a self-lubricating material, which does not need lubrication, which not only saves lubricating oil, but also purifies the working environment.
(5) Poor vibration reduction and high noise.
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.
