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 invention discloses an anti-offset servo motor and a method of using the same, and relates to the technical field of servo motors. The surface of the radiator is formed with a plurality of equidistant heat dissipation grooves arranged side by side to form a circular heat dissipation area, and the center of the plurality of heat dissipation grooves is fixedly connected with a support portion, a bearing seat is arranged in the support portion, and a compensation mechanism is arranged on the output shaft. In the present application, the bearing seat is used to realize the positioning and fitting of the output shaft, so as to ensure the unobstructed rotation of the output shaft, so as to achieve the anti-offset effect of the output shaft; the compensation mechanism plays a buffering effect on the offset of the output shaft, reducing the impact on the output shaft. The wear of the shaft, and the force can be fed back to the output shaft in time to restore the normal rotation state. The shock absorption mechanism greatly reduces the probability of loosening the screws on the servo motor after long-term operation, which indirectly prevents the output shaft from offsetting. effect.

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 rotation phenomenon wh...
