Such as water pump, fan, high speed bearing hydraulic machinery, petroleum machinery, printing machinery, textile machinery, chemical machinery, mining machinery, metallurgical machinery, aviation (helicopter), high-speed power transmission system of ships, steam turbine, piston power mechanical transmission system, crawler Vehicle; and high-speed generator set; high-power mechanical transmission system; applied to high-speed transmission shafting after dynamic balancing. WGP type-with brake disc type; suitable for occasions with disc brakes.Compared with gear coupling, diaphragm coupling has no relative sliding; no lubrication; no sealing; no noise; basically no maintenance; it is more convenient to manufacture; it can partially replace gear coupling. The external teeth are divided into two types: straight teeth and drum teeth; the so-called drum teeth are made by making the external teeth into a spherical surface; the center of the spherical surface is on the gear axis; the tooth side clearance is larger than that of the general gear; the drum-shaped gear coupling can allow more Large angular displacement (relative to straight tooth coupling); can improve the contact conditions of the teeth; improve the ability to transmit torque; extend the service life. Its model is: WH type. The slider coupling has a loud noise; low efficiency; fast wear; generally not used as much as possible; only used in occasions with very low speed. WGZ type-with brake wheel type; suitable for occasions with brake shoe brakes. Third, the chain coupling The chain coupling uses a common chain; at the same time, it meshes with two parallel sprockets with the same number of teeth; the main difference between the chain couplings of different structural forms is the use of different chains; the common ones have double-row rollers Chain couplings; single-row roller chain couplings; toothed chain couplings; nylon chain couplings, etc. The common feature of the universal coupling is that the amount of angular compensation is large; the angle between the two axes of the universal coupling of different structural forms is different; generally between 5 and 45 degrees.
