Midon Industry - American standard cone sleeve pulley is an efficient wheel axle transmission method that uses axial expansion design to increase axial torque extension and transmit excessive multiplied torque radially to flanges and screws,
It has both axial and radial composite and precise force transmission without gaps. It realizes long-distance transmission and changes in speed regulation, which is its core feature. It is a relatively perfect product in gear transmission.
1、 Core characteristics of American standard QD cone sleeve pulley:
1. Self centering function: The contact surface between the cone sleeve and the shaft is conical, and uniform radial clamping force is generated by axial compression during installation, automatically achieving precise centering between the shaft and the hub and reducing eccentric vibration.
2. Keyless connection: No keyway is required to avoid stress concentration caused by keyway machining errors and extend the service life of the shaft.
3. High load-bearing capacity: Cone friction transmits torque, suitable for high-speed and heavy-duty working conditions.
2、 Main advantages of Midon Industrial American standard QD cone sleeve pulley:
1. Quick installation and disassembly: Installation or disassembly can be completed by tightening or loosening the bolts on the cone sleeve, without the need for special tools, resulting in high maintenance efficiency.
2. High transmission efficiency: The belt groove design optimizes the belt contact area, reduces slippage, and the transmission efficiency can reach over 95%.
3. Strong universality: Suitable for multiple shaft diameters: The same QD cone sleeve can be adapted to different shaft diameters (by replacing the inner lining of the cone sleeve or adjusting the specifications), reducing the number of spare parts.
4. Convenient maintenance: No need to disassemble or replace the belt. The QD structure allows for direct loosening of the taper bolt and movement of the pulley, without the need to disassemble the entire transmission system to replace the belt.
3、 Commonly used in the device industry:
In the field of heavy industry, heavy-duty equipment such as mining machinery, fans, pumps, etc., and automated production lines require frequent maintenance of conveyor belts and transmission systems. Agricultural machinery: equipment with high vibration such as combine harvesters and tractors.
