Compensation features and applications of NGCLZ type intermediate shaft drum gear coupling with brake wheel:
The so-called drum-shaped tooth means the external tooth is made into a spherical surface, the center of the spherical surface is on the gear axis, and the tooth side clearance is larger than that of ordinary gears. The drum-shaped tooth coupling can allow greater angular displacement (compared to the straight tooth coupling) , It can improve the contact conditions of the teeth, increase the torque transmission ability, and prolong the service life.The contact state along the tooth width when there is angular displacement.It has the ability to compensate for axis deviation in radial, axial and angular directions. It has the advantages of compact structure, small turning radius, large carrying capacity, high transmission efficiency, low noise and long maintenance cycle. It is especially suitable for low-speed and heavy-duty conditions, such as Metallurgy, mining, lifting and transportation industries, and also suitable for petroleum, chemical, general machinery and other machinery.
 NGCLZ type intermediate shaft drum gear coupling with brake wheel. The gear coupling is composed of an inner 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 center of the spherical surface is on the gear axis. The tooth side clearance is larger than that of ordinary gears. The drum-shaped tooth coupling can Allows a larger angular displacement (compared to the straight tooth coupling), which 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 angular displacement.
