NGCL drum gear coupling with brake wheel

NGCL drum gear type with brake wheelCouplingIt is especially suitable for low-speed and heavy-duty working conditions, such as metallurgy, mining, lifting and transportation industries, and also suitable for shaft transmission of various types of machinery such as petroleum, chemical industry, and general machinery.

  NGCL with brake wheelDrum toothCouplingThat is, the external teeth are made into a spherical surface, the spherical surface is on the gear axis, and the tooth side clearance is larger than that of the general gear. The drum-shaped gear coupling can allow a larger angular displacement (compared to the straight tooth coupling), which can improve the teeth Contact conditions, improve the ability to transmit torque, and extend the service life. Drum-shaped gear couplings are rigid-flexible couplings. Gear couplings are composed of an inner gear ring with the same number of teeth and a flange with external teeth. It is composed of couplings and other parts. The external teeth are divided into two types of teeth, straight teeth and drum teeth, and they are in contact along the width of the tooth when there is an angular displacement.It has radial, axial and angular axis deviation compensation capabilities, with compact structure, small turning radius, large carrying capacity, high transmission efficiency, low noise and long maintenance cycle.
NGCL drum gear coupling with brake wheel is particularly suitable for low-speed and heavy-duty working conditions, such as metallurgy, mining, lifting and transportation industries, and also suitable for shafting transmission of various machinery such as petroleum, chemical, general machinery, etc. When the gear coupling is working, the two shafts produce relative angular displacement. The tooth surfaces of the internal and external teeth periodically slide relative to each other in the axial direction, which will cause the wear of the tooth surface and power consumption. Therefore, the gear coupling needs to have a good and Work in a sealed state.
NGCL drum gear couplings with brake wheels have small radial dimensions and large carrying capacity. They are often used in shaft transmissions under low-speed and heavy-duty conditions. Highly and dynamically balanced gear couplings can be used for high-speed transmission. Such as the shaft transmission of a gas turbine.
