Rokee® Customized ROQ Gear Type Drum Coupling for Customers, Rokee® is a well-known high-quality supplier of couplings and technical services in China.
The gear type drum coupling is a flexible connection device designed specifically for lifting equipment, mainly used for power transmission between the output shaft of the reducer and the wire rope drum. This type of coupling combines the dual advantages of a drum toothed coupling and a radial load-bearing structure, capable of transmitting large torque while bearing significant radial loads, and is a key transmission component of the crane lifting mechanism.
Core design features
Drum shaped meshing system: The outer gear sleeve adopts a spherical drum shaped tooth design, with a tooth clearance 30% -50% larger than that of ordinary gears, allowing for ± 5mm axial displacement, ± 3mm radial displacement, and 1.5 ° -2.5 ° angular deflection
Dual functional structure: Torque is transmitted through the drum shaped teeth formed by the outer gear shaft sleeve and the outer sleeve, while the automatic adjustment bearing pair is formed by the outer spherical bearing ring and the inner bearing surface of the outer sleeve, with a radial bearing capacity of up to 18-355kN
Intelligent monitoring design: Equipped with a built-in wear indicator pointer, the wear status of the tooth surface can be predicted and the risk of failure can be alerted in advance by observing the relative displacement between the pointer and the scratch (standard value m1)
Structural composition
Power transmission unit: outer gear shaft sleeve with drum shaped teeth (material 42CrMo, hardness HRC52-58) and outer sleeve with inner gear ring (QT600-3)
Bearing unit: self-aligning bearing pair formed by outer spherical bearing ring (GCr15 bearing steel) and inner bearing surface
Auxiliary system: Double lip seal ring (nitrile rubber), lubrication channel (PT1/4 oil nozzle), vent hole and end cap assembly
The toothed drum coupling is developing towards higher reliability, longer lifespan, and intelligent monitoring through continuous technological innovation, providing a safer and more efficient transmission solution for modern lifting equipment. Proper selection and scientific maintenance can reduce the comprehensive use cost of equipment by more than 30%.
