Problems solved by technology

[0003] The servo motors currently used are fixed on the motor fixing frame first, and then the motor fixing frame is fixed on the machine. The servo motor and the motor fixing frame are fixed by fixing screws. The vibration of the machine makes the fixing screws used to fix the servo motor exist. Looseness will cause the servo motor and the motor fixing frame to vibrate. Long-term operation will cause the output shaft of the motor to shift. If the stability of the output shaft is not high, it is easy to shift during the rotation process. Any slight shift It will cause the parts of the output shaft to wear and affect the normal use and service life of the servo motor

Abstract

The present invention discloses an anti-offset servo motor and a using method thereof, and relates to the technical field of servo motors. The anti-offset servo motor comprises a servo motor, a frontcover on the front surface of the servo motor, a mounting base on the bottom surface of the servo motor, and an output shaft of the servo motor; the surface of the front cover is provided with a plurality of equally spaced heat dissipation slots arranged in parallel to form a circular heat dissipation area; a support portion is fixedly connected to the center of the plurality of heat dissipation slots; a bearing seat is arranged inside the support portion; and a compensation mechanism is arranged on the output shaft. According to the technical scheme of the present invention, fixed installation for the output shaft is realized through the bearing seat, and the anti-offset effect of the output shaft can be achieved while ensuring that the output shaft rotates unimpededly; the compensation mechanism plays a buffer role when the output shaft is offset, wear of the output shaft is reduced, and the force can be re-fed back to the output shaft in time to restore a normal rotation state of the output shaft; and by using a damping mechanism, the probability of loosening the screws on the servo motor after long-term operation can be greatly reduced, so that the damping mechanism indirectlyplays a role in preventing the output shaft from being offset.

Description

technical field [0001] The invention relates to the technical field of servo motors, in particular to an anti-offset servo motor and a use method thereof. Background technique [0002] Servo motor refers to the engine that controls the operation of mechanical components in the servo system. It is an auxiliary motor indirect transmission device. The servo motor can control the speed and position accuracy very accurately. It can convert the voltage signal into torque and speed to drive the control object. , the rotor speed of the servo motor is controlled by the input signal, and can respond quickly. In the automatic control system, it is used as an actuator, and has the characteristics of small electromechanical time constant, high linearity, and starting voltage. The signal is converted into angular displacement or angular velocity output on the motor shaft. It is divided into two categories: DC and AC servo motors. Its main feature is that there is no self-rotation phenomen...
