AI Technical Summary
In the existing technology, the method of driving the ball screw by the servo motor through the synchronous belt deceleration has problems such as synchronous belt aging and loosening, belt tooth wear, and high noise during high-speed operation.
The slide block structure is directly driven by a servo motor. The servo motor is directly connected to the lead screw. The spline connection and involute spline tooth profile design achieve efficient and reliable torque transmission, eliminating the need for transmission components such as reducers and synchronous belts.
It achieves structural safety, stability, and durability, extends service life, and features high overall structural rigidity, rapid response, high transmission precision, high efficiency, and low cost, while solving the problems of synchronous belt aging and loosening, as well as excessive noise.
