a servo motor

Abstract

The invention relates to a servo motor, which comprises a box body, cover plates, a transmission assembly, an input rotating shaft, a swing assembly, an output assembly and a motor main body, whereinthe box body is installed at the left end of the motor main body, both the front and rear ends of the box body are one cover plate, the right end of the input rotating shaft is connected with an output shaft of the motor main body through a coupling, the middle part of the input rotating shaft passes through the upper right side wall of the box body, the transmission assembly is installed at the left end of the input rotating shaft, the upper end of the transmission assembly is installed on the upper side wall of the box body, the swing assembly is distributed below the transmission assembly,the swing assembly is installed on the box body, the output assembly is located at the left inner side of the box body, and the output assembly is connected with the box body. The servo motor solves the problems that the servo motor is poor in stability and great in swing amplitude deviation when performing cyclic swinging and rotation, the servo motor has a hidden danger of driving an external swinging object to be damaged when the servo motor is damaged and that the safety is poor.

Description

technical field [0001] The invention relates to the technical field of electromechanical products, in particular to a servo motor. Background technique [0002] Nowadays, high-end toys, industrial robots, and teaching demonstrations often use circularly swinging motors. This kind of motor is mostly driven by a servo motor. The servo motor realizes the swing of the external execution end by controlling the forward and reverse rotation of the motor. [0003] The specific problems existing when using the servo motor to drive the external actuator to swing are as follows: [0004] 1. When the servo motor swings through the positive and negative rotation of the motor for a long time, the cumulative error will gradually increase, resulting in a large deviation in the swing amplitude of the motor; the swing stability is poor; [0005] 2. When the servo motor drives the external execution end to swing through forward and reverse rotation, there will be vibration at the node where i...

AI Technical Summary

Problems solved by technology

[0004] 1. When the servo motor swings through the positive and negative rotation of the motor for a long time, the cumulative error will gradually increase, resulting in a large deviation in the swing amplitude of the motor; the swing stability is poor;

[0005] 2. When the servo motor drives the external execution end to swing through forward and reverse rotation, there will be vibration at the node where it swings alternately, resulting in poor swing stability of the motor;

[0006] 3. The long-term positive and negative rotation of the servo motor will affect the service life of the motor, causing the shaft of the motor to be off-axis or broken. If the shaft of the motor is damaged, the shaft cannot be protected, resulting in damage to the external execution end.
