How to identify the tooth shape of snake spring coupling

In the process of operation of the snake spring coupling, the coupling parts need to rely on the axial force of the active end tooth surface to drive the driven end of the snake spring to transfer torque, so as to avoid the occurrence of resonance phenomenon to a large extent. The elastic variable generated by the snake spring coupling and the spring when transferring torque enables the mechanical system to obtain better vibration reduction effect. Its average damping rate is more than 36 percent. The contact point between the spring and the tooth surface, that is, the change of torque, is changed with the size of the transmitted torque, the transmission characteristics of the snake spring coupling is variable stiffness.

Serpentine spring coupling in the serpentine spring placed on the slot, will be blocked by the clamp and affect the placement of the serpentine spring, then the connecting block can be turned up, and the clamp close to the end of the splint is connected to the upper surface of the splint, so that the clamp is located above the clamp slot, the serpentine spring through the clamp on the clamp. Then the snake spring can be placed on the corresponding position of the clip slot to complete the placement of the snake spring and turn down the clamp, which can realize the insertion and coordination of the parts to be bent in the snake spring and the clamp, and the bending operation of the snake spring can be carried out. Due to a layer of oil scale, corrosion products and other sediments deposited on the surface of the thread, it is not easy to remove the bolt, especially for the serious corrosion of the bolt, disassembly is very difficult. Select the appropriate tool for the removal of the connecting bolt, because the force surface of the outer or inner hexagon of the bolt has slipped and damaged, and the removal will be difficult. The snake spring coupling bears a large range of variable load, starting safety two half couplings and the spring contact tooth surface is curved, when the transfer torque increases, the spring will deform along the tooth curve surface, so that the two half couplings act on the spring point close to the spring.

If the gear of the snake spring coupling is curve type: when its load is small, then its straight part is basically parallel to the axis of the connection; When the load increases, the deformation of the snake spring increases, the contact arc surface with the teeth also increases, and the distance between the contact point and the teeth becomes shorter and shorter, and the stiffness increases. The relative Angle of the two halves of the coupling has a nonlinear relationship with the torque transmitted. The buffering effect generated when the spring deforms along the tooth arc is generated by the power transmission, especially when the machine is started or the strong impact load.
