Rokee® Customized High-speed Crown Gear Coupling for Customers, Rokee® is a well-known high-quality supplier of couplings and technical services in China.
The high-speed drum shaped gear coupling is mainly composed of an inner gear ring, an outer gear shaft sleeve, an end cover, and a sealing device. Its key feature is that the tooth tip of the outer gear shaft sleeve is designed in a drum shape, and the tooth surface is in a circular arc shape. This design enables the coupling to adapt to displacement compensation at certain angles, radial and axial directions while transmitting torque.
During high-speed operation, the torque of the driving shaft is transmitted to the inner gear ring through the outer gear sleeve, which in turn drives the driven shaft to rotate. Due to the presence of drum shaped teeth, when there is relative displacement between the two axes, the contact point between the tooth surface of the drum shaped teeth and the tooth surface of the inner ring gear will change, thereby achieving displacement compensation function. This displacement compensation capability enables the high-speed drum shaped gear coupling to maintain stable transmission performance under complex working conditions.
Lubrication and cooling are crucial for high-speed drum gear couplings. Lubricating oil is usually used for continuous lubrication to ensure good contact between tooth surfaces and reduce wear. Lubricating oil should be discharged smoothly to avoid the accumulation of water and dirt. At the same time, some important high-speed drum shaped gear couplings can also adopt the structure of oil collecting groove holes, which use the centrifugal force generated by the high-speed operation of the coupling to spray oil into the meshing area of the inner and outer teeth, ensuring sufficient lubrication.
High speed drum shaped gear couplings are widely used in various industrial fields that require high-speed and heavy-duty transmission, such as:
Metallurgical industry: used in large equipment such as rolling mills and blast furnaces to connect motors and reducers, reducers and working machines, etc., to meet their heavy-duty and high impact working conditions.
Mining machinery, such as crushers, ball mills, and other equipment, work in harsh environments and are prone to shaft displacement. Drum type gear couplings, with their excellent displacement compensation capabilities and high reliability, ensure the stable operation of the equipment.
Petrochemical industry: Used in equipment such as pumps and compressors to transmit power, its corrosion resistance and stable transmission performance ensure the continuity and safety of chemical production.
Power industry: widely used in equipment such as steam turbine generators and fans, providing reliable power transmission for power production.
