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、 Efficient transmission and high power support
1. High power transmission capability: The BST type American standard QD belt pulley design is compact and suitable for high-power power transmission scenarios, especially in industrial and agricultural machinery, where it performs well and can effectively transmit high torque requirements.
2. High balance level: The dynamic balance level reaches G6.3, ensuring smooth operation, reducing vibration and noise, and suitable for precision transmission systems.
3. High precision and durability: high-precision CNC machine tools are used to process groove shapes with low roughness, reducing belt wear, extending belt life, and ensuring transmission efficiency.
2、 High quality materials and craftsmanship
1. Material selection: HT250 gray cast iron or ductile iron (QT450) is mainly used, which has high strength, wear resistance, and impact resistance. After aging treatment, internal stress is eliminated to ensure long-term use without deformation.
2. Surface technology: Chemical treatment is used to cover the anti-corrosion film, and spray paint or phosphating treatment is applied to enhance the anti-corrosion ability and improve the appearance aesthetics.
3. Anti loosening design: When installing the bolt, hold it against the bottom of the blind hole of the cone sleeve and use reverse thrust to achieve a "double nut" anti loosening effect, avoiding loosening during operation.
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.
