Rokee® Customized High Speed Drum Gear Coupling Exported To Europe 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 a rigid flexible coupling device composed of an inner gear ring and a flange half coupling with outer teeth.
Core Features
Drum shaped tooth design: The outer teeth are made into spherical surfaces (with the center of the ball on the gear axis), and the tooth side clearance is increased by 30% -50% compared to straight tooth couplings
Composite compensation mechanism: can simultaneously compensate for axial (± 1.5mm), radial (0.2-0.5mm), and angular displacement (maximum 1.5 °)
Dynamic meshing principle: Torque transmission is achieved through multi-point contact on the drum shaped tooth surface, with a transmission efficiency of 99.7%
Compared with spur gear couplings, its angular displacement compensation capability is increased by 50%, and its load-bearing capacity is increased by 15% -20% under the same structural dimensions. The typical speed range is 4000-12000r/min, and the special design can reach 20000r/min.
Transmission performance
The torque density is 20% higher than that of the straight tooth type, and the transmitted torque is greater under the same outer diameter
Vibration reduced by 35%, and a gas turbine application showed that the bearing life was extended by 2.8 times
No reverse clearance, servo system positioning accuracy reaches ± 0.005 °
Reliability Design
The forced thin oil lubrication system reduces wear to only 10% of grease lubrication
The contact area of the tooth surface has been increased to 85% (about 60% for straight tooth type)
Using 42CrMo alloy steel, the fatigue life exceeds 10 ^ 7 cycles
Typical application scenarios
