Abstract

Disclosed is a linear motion conversion method for a servo motor. According to implementation steps, the parts of a rotor, a ball screw, a winding stator core, a brake, a taper-lock, a shaft sleeve, an angular contact bearing, a front end cover, a back end cover, a dust cover, a rubber block, a fixed block, an adjusting block, an annular seal ring, a brake and the like are included. A ball screw kinematic pair is connected onto the rotor of the servo motor and the ball screw is used for conversion of rotary motion of the rotor into linear motion when the rotor rotates. The rotor and the ball screw are connected via the taper-lock, and an outside is tightened via a round nut with a round nut and. Electric front-end dust cover plus seals deal with the winding of the stator core be casting resin sealed, placed tail motor brake. According to the invention, the structure is compact, stability is high and conversion of the rotary motion of the motor into back-and-forth linear motion achieved.

Description

technical field [0001] The invention relates to a motion conversion method of a servo motor, in particular to a motion conversion method of a servo motor capable of converting rotary motion into linear motion. Background technique [0002] Servo motors are used more and more widely, and a large number of linear motion servo motors are required in the fields of robotics, numerical control, automobiles, and aerospace. The traditional servo motor operates in rotary motion, and a complex transmission mechanism needs to be added externally to achieve linear motion. Due to the existence of a motion form transformation link in the middle, the stiffness of the transmission system is reduced, causing elastic deformation of the intermediate link, thereby reducing the robustness of the system. , will cause mechanical resonance in occasions such as numerical control machine tools. Therefore, it is of great significance to develop a servo motor that can directly drive a mechanical load ...
