CL type gear couplingIt is a removable rigid coupling. It consists of two sleeves with internal teeth and two sleeves with external teeth. The sleeve and the shaft are connected by a key, and the two housings are connected by bolts. There is a sealing ring between.The number of teeth of the internal gear is equal to that of the external gear, and an involute tooth profile with a pressure angle of 20° is usually used.When working, torque is transmitted by meshing gear teeth.Because there is a large gap between the gear teeth, it can compensate for the misalignment and deflection of the two shafts. In order to reduce the wear of the gear teeth and the frictional resistance of the relative displacement, lubricating oil is injected inside.The angular displacement of the gear coupling is allowed to be 30'.Gear coupling has radial, axial and angular axis deviation compensation capabilities. It has the advantages of compact structure, small gyration radius, large transmission torque, low transmission, low noise and long maintenance cycle, and is especially suitable for low-speed heavy-duty workers. Conditions, such as metallurgy, mining, lifting and transportation industries, and also suitable for shaft transmission of various heavy machinery such as petroleum, chemical, general machinery and so on.
