The brake wheel drum gear coupling is a special type of drum gear coupling that combines the advantages of traditional drum gear couplings and integrates a brake wheel function. This unique design expands its applicability in various industrial applications. This coupling consists of components such as an internal gear ring with the same number of teeth as the flange half-coupling with external teeth, which come in two types: straight teeth and drum-shaped teeth. The drum-shaped design forms a spherical external gear, with the spherical center aligned on the gear axis, resulting in a larger tooth-side clearance than typical gears. This allows for greater angular displacement, improves tooth contact conditions, enhances torque transmission capacity, and extends service life. The addition of the brake wheel further enhances its functionality and safety, making this coupling particularly important in systems requiring braking control.
The main features of the brake wheel drum gear coupling include the following:
- Compact Structure: With the ability to compensate for radial, axial, and angular misalignments, it is compact and has a small turning radius.
- High Load Capacity: Compared to the CL-type straight-tooth coupling, the drum gear coupling has a higher load capacity and transmission efficiency.
- Allows Angular Displacement: The drum-shaped teeth allow greater angular displacement, improving tooth contact conditions, enhancing torque transmission capability, and extending service life.
- Integrated Braking Function: By integrating the brake wheel, it adds braking control capability to the coupling, increasing system safety and controllability.
- Wide Applicability: Suitable for shaft transmission under low-speed heavy-load conditions, as well as high-speed transmission scenarios, offering excellent sealing and environmental resistance.
Additionally, the design and manufacturing process of the brake wheel drum gear coupling considers multiple factors, such as the selection of elastomer materials and the relative sliding between internal and external teeth. These considerations ensure reliable performance and a long service life under various working conditions. This type of coupling is widely used in various industrial equipment, such as compressors and generators, and offers specific technical parameters and dimensions to meet the demands of different applications.
