ZLL type elastic pin coupling
ZLL typeElastic pinCouplingIt uses several pins made of non-metal elastic materials and is placed in the flange holes of the two halves of the coupling. The two halves of the coupling are connected by the pins. The coupling has a simple structure, easy to manufacture, and flexible in assembly and disassembly. The components are more convenient, and there is no need to move the two couplings.The material of the elastic element (column pin) is generally selected from nylon 6, which has the ability to slightly compensate for the deviation of the two axes. The elastic part is sheared during operation and has poor working reliability. It is only suitable for medium-speed transmission shaft systems with very low requirements. For working conditions with high reliability requirements.
