Among a wide range of couplings, the JS type casing radially mounted coupling has the advantages of small size, large transmission torque, absorption of coupling errors, and excellent advantages. It is a common coupling two transmission in medium and heavy machinery. Parts of the shaft.
The range of transmitted power and speed is large.The structure is compact, works, and can achieve a larger transmission ratio.Transmission and long service life.The disadvantages are: high manufacturing and installation requirements.
The curvature radius of the bulge curve is proportional to the single-sided thinning of the internal tooth, so the bulge circle radius should be as large as possible.
The teeth on the outer gear sleeve in the tooth tip direction are bulge teeth, and the tooth thickness gradually decreases from the middle to the two sides. The teeth on the ring gear that mesh with the teeth are straight teeth.The tooth top and tooth surface of the external gear shaft are curved, and the entire coupling is a double-joint flexible coupling, which can adjust the large deflection angle between the two shafts.
Since the selected material of the LXD single-flange star elastic coupling is cast iron, its weight is 38.8 kg, so that the motor wastes a lot of electric energy during the water supply operation, which affects the efficiency of the unit and increases the operating cost.
Coupling materials are roughly divided into sections (round steel), castings (cast iron or cast steel), forgings, etc., and cast steel and forgings are most of the choices of coupling materials.
1. The plum blossom coupling is a widely used coupling, also called a claw coupling;
Under normal circumstances, the coupling and shaft connection are driven by keys, and the keys are all national standard.The motor shaft and the coupling can be axially fixed with transitional fit or tight fit.
