NGCL type with brake wheel

NGCL type drum gear coupling with brake wheel (JB/ZQ4644-97)
　　The so-called drum-shaped tooth is to make the external teeth 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 larger angular displacement (compared to the straight tooth coupling) , It can improve the contact conditions of the teeth, increase the ability to transmit torque, and prolong the service life. The drum-shaped gear coupling belongs to the rigid-flexible coupling. The gear coupling is composed of an inner ring gear with the same number of teeth and an outer belt The tooth flange half-coupling and other parts, the external teeth are divided into two types of tooth shapes, straight teeth and drum teeth, and 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 shaft transmission of various machinery such as petroleum, chemical industry, general machinery, etc. When the gear coupling is working, the two shafts produce relative angular displacement, and the tooth surface cycle of the internal and external teeth The 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.Gear couplings have small radial dimensions and large load-bearing capacity. They are often used in shafting transmissions under low-speed and heavy-duty conditions. High-precision and dynamically balanced gear couplings can be used for high-speed transmissions, such as gas turbine shafting. transmission.
