Description

Technical Field

[0001] The utility model relates to the technical field of synchronous transmission devices, in particular to a precision sandwich torque synchronous transmission device. Background Art

[0002] The precision sandwich torque synchronous transmission device is a device used to transmit torque and achieve precise synchronization, which is commonly found in mechanical transmission systems. It usually consists of two or more interlocking gears or friction wheels, in which the sandwich device is used to ensure a tight connection between the wheel and the shaft in order to transmit torque. By using this precision sandwich torque synchronous transmission device, precise torque transmission and synchronous motion can be achieved. It is suitable for mechanical transmission systems that require highly precise control and stability, can reduce energy loss and friction loss during transmission, improve transmission efficiency, ensure stable connection between transmission elements, prevent slippage or dislocation during transmission, and maintain system stability and reliability, which is particularly important for equipment that runs for a long time and works under high load.

By setting a transmission controller that independently drives the second transmission device, the first transmission device no longer drives the second transmission device at the same time, so that when the clamp enters the running channel, the upper and lower ends are driven at the same speed, thereby avoiding the wrinkling of the PCB soft board clamped by the clamp.
