Problems solved by technology

[0005] In the process of R&D and manufacturing, the inventors found that the existing servo motors and couplings have the following problems: first, the existing couplings and the connection with the servo motors have complex structures and low cost. Higher, more inconvenient for installation and maintenance; second, as the main power transmission component, the coupling has too many transmission links

Embodiment Construction

[0028] The implementation of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0029] Such as Figure 2 to Figure 5 Shown is a preferred embodiment of the present invention.

[0030] Such as figure 2 , image 3 As shown, a servo motor with a built-in coupling includes a motor output shaft 6, a coupling bearing 5 and a motor end cover 4. The motor output shaft 6 is positioned through the coupling bearing 5, and the coupling bearing 5 is fixed on the motor on the end cap 4. Of course, the above-mentioned servo motor also includes other components such as a rotor, and since these components belong to the prior art in this field, details will not be described here.

[0031] The coupling bearing 5 includes a bearing outer ring 51 and a bearing inner ring 52 . Of course, as a bearing, the coupling bearing also includes steel balls, cages, etc., and since these components belong to the prior art in this field, they ...

Abstract

The invention discloses a servo motor with a built-in coupling. The servo motor comprises a motor output shaft, a coupling bearing and a motor end cover, wherein the motor output shaft is positioned by the coupling bearing, and the coupling bearing is fixed on the motor end cover; and the coupling bearing consists of a bearing outer ring and a bearing inner ring, the side of the bearing inner ring, close to the motor output shaft, is of a shaft sleeve connection part which protrudes out of the bearing outer ring and is fixedly connected with the end of the motor output shaft, the other side of the bearing inner ring is of a transmission connection part which can be fixedly connected with an external transmission shaft, and the shaft axis of the shaft sleeve connection part of the bearing inner ring, the shaft axis of the transmission connection part of the bearing inner ring, and the shaft axis of the motor output shaft are coincident. By adopting the technical scheme, the servo motor has a simple structure and low cost, is compact in structure and convenient to install, improves the bearing strength, reduces transmission links, and improves the driving accuracy of the motor.

Description

technical field [0001] The invention relates to a servo motor, in particular to a built-in coupling type servo motor. Background technique [0002] Servo motor (servo motor) refers to the engine that controls the operation of mechanical components in the servo system, and is an auxiliary motor indirect transmission device. The servo motor can control the speed and position accuracy very accurately, and 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. It can convert the received electrical signal Converted to 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 ...
