The common types and models of rigid flange coupling are: YL type flange coupling, YLD type flange coupling, JQ type jacket coupling, Gy type ordinary flange coupling, gys type centering tenon flange coupling, GYH type centering ring flange coupling.
The flange coupling can be made of gray cast iron or carbon steel, and cast steel or forged steel shall be used when the heavy load or the circumferential speed is greater than 30 m / s. Flange coupling has a high requirement for two shafts to be neutral. When the two shafts have relative displacement, it will cause additional load in the parts and worsen the working condition, which is its main disadvantage. However, due to its simple structure, low cost and large torque transmission, when the speed is low, there is no impact and the rigidity of the shaft is large
The basic performance parameters are mainly introduced from YL type ordinary rigid flange coupling and Gy type flange coupling
1. YL, YLD flange coupling
The order mark is as follows: such as yl6 flange coupling
Driving end: J-shaped shaft hole, A-shaped keyway, d = 30mm, l = 82mm
Driven end: type J1 shaft hole, type B keyway, d = 25mm, l = 44mm
It is yl6-ja30 * 82 / j1b25 * 44
