Rokee® Customized Large Curved Tooth Coupling for Customers, Rokee® is a well-known high-quality supplier of couplings and technical services in China.
As a key component in modern industrial transmission systems, curved tooth couplings play an irreplaceable role in the fields of heavy machinery and precision equipment. This type of coupling, with its unique drum shaped tooth design, not only efficiently transmits torque, but also effectively compensates for installation deviations in the axial, radial, and angular directions, thereby significantly improving the stability and service life of the transmission system.
Curved tooth coupling belongs to a type of rigid flexible coupling, and its core design concept is to achieve shaft to shaft connection through a special gear structure while allowing a certain degree of relative displacement. Compared with traditional spur gear couplings, drum gear couplings have significantly improved in multiple performance indicators and have become the preferred choice for modern industrial transmission devices.
Basic structure: A complete curved tooth coupling typically includes the following main components:
External gear shaft sleeve: a half coupling with drum shaped teeth, usually made of high-strength alloy steel
Internal gear ring: an annular component with straight teeth that meshes with an external gear shaft sleeve
Sealed end cap: prevents lubricant leakage and blocks external contaminants from entering
Connecting bolt: used to fix the coupling at the shaft end
Lubrication system: including oil holes, oil passages, and grease/oil chambers, etc
Working principle: When the driving shaft rotates, torque is transmitted to the driven shaft through the meshing of the outer gear sleeve and the inner gear ring. When there is relative displacement between the two axes, the special profile of the drum shaped teeth allows for relative sliding between the tooth surfaces, thereby compensating for axis deviation without generating excessive additional loads. This design enables the coupling to adapt to a certain range of installation errors and shaft deformation during operation while transmitting torque.
Widely applicable fields: The characteristics of curved tooth couplings make them play a key role in multiple industrial fields:
Metallurgical industry: rolling mills, continuous casting equipment, heavy-duty reducers
Mining machinery: Mine hoists, crushers, conveying equipment, suitable for impact loads and dust environments
Energy sector: Hydroelectric power generation units, wind power yaw/pitch systems
Heavy engineering: Port cranes (such as G Ⅱ CLZ type), shield tunneling machines, large test benches
Special Environment: Semiconductor Vacuum Equipment
