CL type gear coupling

CL typeGear couplingIt belongs to a rigid-flexible coupling. The gear coupling is composed of an internal gear ring with the same number of teeth and a flange half coupling with external teeth.The external teeth are divided into straight teeth and drum teeth. The so-called drum teeth means that the external teeth are made into a spherical surface. The spherical surface is on the gear axis. The tooth side clearance is larger than that of ordinary gears. Drum gear couplings are allowed. Larger angular displacement (compared to straight tooth coupling) can improve the contact conditions of the teeth, increase the torque transmission capacity, and prolong the service life.The contact state along the tooth width when there is an angular displacement.It has the ability to compensate for axis deviation in radial, axial and angular directions, and has the advantages of compact structure, small turning radius, large carrying capacity, high transmission efficiency, low noise and long maintenance period. It is especially suitable for low-speed and heavy-duty conditions, such as When the shaft transmission gear coupling of metallurgy, mining, lifting and transportation industries, and also suitable for various machinery such as petroleum, chemical industry, general machinery, etc., when working, the two shafts produce relative angular displacement, and the tooth surfaces of the internal and external teeth are periodic. Relative sliding in the axial direction will inevitably cause tooth surface wear and power consumption. Therefore, the gear coupling must work in a good and sealed state.

CL type gear coupling is suitable for connecting two horizontal axis transmission shaft systems, has the performance of compensating the relative deviation of the two shafts, and transmits a nominal torque of 710-1000000N.m. CL type gear coupling is a removable rigid coupling. It consists of two housings with internal teeth and two sleeves with external teeth. The sleeve and the shaft are connected by keys, and the two housings are connected by bolts. One body, with a sealing ring between the shell and the sleeve.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 drum gear coupling is allowed to be 30'.Gear coupling has radial, axial and angular axis deviation compensation capabilities, has the advantages of compact structure, small gyration radius, large transmission torque, high transmission efficiency, low noise and long maintenance period, especially suitable for low-speed heavy Load conditions, such as metallurgy, mining, lifting and transportation industries, and also suitable for shafting transmission of various heavy machinery such as petroleum, chemical industry, general machinery and so on.
