迈动工业-美标锥套皮带轮,是一种通过轴向胀紧设计,加大轴向力矩延伸,向法兰和螺丝径向过度倍增力矩传递的一种高效轮轴传动方式,

既有轴向也径向复合交溶无隙精准传力,它实现远距传动和配合调速增减的变化,为其核心特性,是轮系传动中比较完美的产品。


1、 Efficient transmission and high power support

1. High power transmission capability: The STB type 5V 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.
