Increasing the transmission torque of the double spiral swing oil cylinder is very important to improve the working efficiency, so how to increase the transmission torque of this oil cylinder in use? The important point is to choose a reasonable spiral pair material, the spiral pair is the connection pair of parts moving with each other. That is, the mutual motion is a thread motion. Thread movement is similar to the screw connection in terms of geometry and force. Both use linear motion to achieve linear motion while transferring energy or force. It can also be used to adjust the mutual position of parts. Sometimes it has several functions. The mother is made of different materials to obtain a lower coefficient of friction. Spiral rods are generally made of medium carbon steel or alloy steel. For example, when the accuracy is not high, 45 # steel is used. When the accuracy is high, 65Mn is used. For small and medium load screws in precision instruments, T8A, T10A or CrMn are generally used.
