Analyze whether the JZMJ diaphragm coupling needs to be assembled
2022-10-31

The JZMJ type diaphragm coupling used by everyone recently can achieve a long amount of elasticity, and its service life is long; it has the functions of compensating the relative offset of the two axes, damping and buffering, and is suitable for connecting two coaxial The transmission shaft of the wire has the function of failure protection, which ensures the reliability of the work. The piercing device only needs three parts to ensure the simplicity of the device. It has radial, angular, axial and torsional elasticity. The elastic block and its The contact surfaces have friction.

Main features of JZMJ type diaphragm coupling:
1. The ability to compensate for the misalignment of the two axes is strong. Compared with the gear coupling, the angular displacement can be doubled, the reaction force is small in the radial displacement, the flexibility is large, and the axial, radial and angular displacements are allowed.
2. It has obvious shock absorption effect, no noise and no wear.
3. High transmission efficiency, up to 95%. Especially suitable for medium and high speed high power transmission.
4. Adapt to high temperature (-80+300) and work in harsh environment, and can act safely under shock and vibration conditions.
5. Simple structure, light weight, small volume, convenient assembly and disassembly. It can be assembled and disassembled without moving the machine (referring to the type with intermediate shaft), and no lubrication is required.
6. It can accurately transmit the rotational speed, and the operation has no slip, which can be used for the transmission of precision machinery.
The metal parts of the JZMJ type diaphragm coupling are made of high-quality gray cast iron GG-25, and its elastic elements are made of synthetic rubber, which has stable torque transmission and small embrittlement effect. Due to the optimized design of the pin and the elastic element, there is no wear even if there is a shaft alignment error. The H-type coupling is used as a high-speed coupling in mechanical equipment, with compact size and convenient production.
