Selection of Rigid Coupling Soft Shaft

rigidityCouplingFlexible shaft selection:
　　1. Determine the diameter according to the torque.In the case of the same transmission power, high speed and small torque are recommended.The flexible shaft uses a small diameter.
　　2. Determine the direction of rotation of the soft shaft according to the direction of rotation. If force is applied in both directions, determine the diameter according to the smallest torque.Change the structure of the flexible shaft and the diameter of the steel wire so that the two-way torque of the flexible shaft is not much different.
　　3. The quality of flexible shafts on the market varies greatly. The breaking torque is easy to measure. It can be measured with a torque wrench. The measured value is a static parameter.Different materials, processing processes, and heat treatment will affect the life of the flexible shaft.
　　4.Measure and calculate the bending radius of the flexible shaft when it is working, and it should not be less than the allowable radius, and avoid excessive bending when designing.The more bending, the greater the power loss and the shorter the life of the flexible shaft.
  　5.Supporting protective tube: metal hose, PU, ​​POM, PA plastic hose.Pay attention to grease when using plastic hoses. Synthetic grease is recommended, which has good compatibility with plastics.If the flexible shaft often swings during use, a hose with a steel wire braid in the middle is recommended.Generally, single-filament and double-filament hoses will be deformed by hand, while hoses with steel wire braid will not deform.
