Torx coupling

The plum-blossom coupling is closely combined with the main body of the two-and-a-half coupling with polyurethane plastic as the elastic element (dispersion diagram), and the main body is mainly made of imported formula alloy aluminum. (Main diagram) The middle polyurethane plastic element is prepared with a unique formula, which has high wear resistance, good temperature resistance and strong toughness, and is stable and durable compared with ordinary plastic parts (comparison diagram of advantages and disadvantages). The plum-blossom body has six petals and eight petals, which are customized according to customer requirements. The fixing method has keyways.

Suitable for servo system, spindle drive, lifting platform, machine tool drive and gearbox motor. Compact, no backlash, providing three kinds of elastomers with different hardness, which can absorb vibration and compensate radial and angular deviation. It is mainly suitable for working places with frequent starting, positive and negative rotation, medium and high speed, medium torque and high reliability, such as metallurgy, mining, petroleum, chemical industry, lifting, transportation, light industry, textile, water pump, fan and so on. The working environment temperature is -20℃~+60℃, the nominal torque is 25~12500Nm, and the allowable speed is 1500~15300r/min. The plum-blossom elastic coupling is mainly composed of two convex teeth which are closely meshed and bear radial extrusion to transmit torque. When the two axes are relatively offset, the elastic element is deformed correspondingly, which plays an automatic compensation role.

The quincunx coupling has the advantages of simple structure, no lubrication, convenient maintenance, easy inspection and maintenance-free, and can run continuously for a long time. High-strength polyurethane elastic elements are wear-resistant and oil-resistant, with large bearing capacity, long service life, safety and reliability. It works stably and reliably, and has good vibration reduction, buffering and electrical insulation performance. It has great axial, radial and angular compensation ability. Simple structure, small radial size, light weight and small moment of inertia, suitable for medium and high speed occasions.
