Flexible gear coupling is a high-performance coupling device that transmits torque through gear meshing. It combines the high torque characteristics of traditional gear transmission with the compensation capability of elastic couplings. This type of coupling consists of two wheel hubs with external teeth and two sleeves with internal teeth. It transmits power through the meshing of the internal and external teeth, and has certain compensation capabilities in the axial, radial, and angular directions.
Wheel hub components: usually forged alloy steel parts with precision machined outer teeth
Sleeve component: a ring-shaped component with internal teeth that meshes with the external teeth of the wheel hub
Sealing system: prevents lubricant leakage and contamination from entering
Lubrication system: including lubrication oil passage and oil storage chamber
When the drive shaft rotates, torque is transmitted to the driven shaft through the meshing of the outer teeth of the hub and the inner teeth of the sleeve. The special tooth profile design between the inner and outer teeth allows for relative displacement within a certain range, thereby compensating for axis deviation.
High torque density: The ability to transmit torque per unit size is superior to most types of couplings
Multi directional compensation capability: can simultaneously compensate for axial displacement (± 5-15mm), radial displacement (0.5-3mm), and angular deviation (0.5 ° -2 °)
Vibration damping characteristics: absorb vibration through oil film damping between tooth surfaces
Long life design: High quality materials and precision machining ensure long-term reliable operation
Compared with traditional rigid couplings, flexible toothed couplings can significantly reduce the additional load caused by centering errors; Compared with elastic couplings, it has higher torque transmission capacity and longer service life.
Heavy industry: rolling mills, mining machinery, large compressors
Energy sector: Steam turbine generator sets, wind power generation equipment
Shipbuilding industry: propulsion shaft system
Petrochemical industry: large pump sets, compressors
Paper Machinery: Large Drum Drive System
Transmission torque demand (rated torque and peak torque)
speed range
Shaft diameter size
Compensation requirements
Environmental conditions (temperature, corrosiveness, etc.)
Ensure that the shaft end clearance meets the manufacturer's requirements
Use specialized tools for installation to avoid hammering
The initial centering error should be controlled within 50% of the coupling compensation capacity
Lubricate according to specifications and ensure sufficient lubrication before the first operation
Regularly check the lubrication condition (every 3-6 months)
Monitoring temperature rise (under normal operating conditions, the temperature rise does not exceed 30 ℃ of the ambient temperature)
Regularly check the sealing condition
Abnormal vibration: usually caused by poor alignment or wear, requiring re alignment or replacement of components
Lubrication failure: manifested as overheating and abnormal noise, lubricant needs to be replaced
Tooth wear: Check the lubrication system and evaluate the remaining life of the coupling
As a key component of modern mechanical transmission systems, the development of flexible gear couplings will continue to drive industrial equipment towards higher efficiency and reliability. The correct selection, installation, and maintenance of flexible gear couplings are of great significance for ensuring the long-term stable operation of equipment.
