It is dynamic to be arranged in the feed screw nut.
In such scheme, the side of the bearing block and the motor connection is provided with the first opening, first opening
Diameter be more than the diameter of the output shaft, the bearing block is provided with the second opening away from the opposite side of the motor, described the
The inwall of two openings is fixed with bearing, and the inner ring of the bearing is fixedly connected with the outer peripheral face of the feed screw nut.
In such scheme, the outer end of the output shaft is provided with ring flange, and the feed screw nut passes through with the output shaft
