Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] Such as figure 2 As shown, the motor with torque sensor of the present invention includes a motor shaft 7 and a motor front cover 5 . A torque sensor 8 is sleeved on the outwardly extending end of the motor shaft 7, and the rear end of the housing of the torque sensor is fixedly connected to the front end cover 5 of the motor. connect.

[0023] When the motor is working, the torque sensor 8 rotates together with the motor shaft 7, and simultaneously tests the working torque on the motor shaft 7. And its shell 10 is then fixed together with the motor front end cover 5, does not rotate with the motor rotating shaft 7. There is a pair of rolling bearings 11 between the housing 10 and the motor shaft 7 so that they can rotate relative to each other without affecting each other.

[0024] Such as image 3 As shown, the torque sensor 8 includes a ...

Abstract

The invention relates to an electric motor with a torque sensor. The torque sensor is sheathed on the outwards extending end of a rotary shaft of the electric motor, the back end of an outer shell of the torque sensor is fixedly connected with a front end cover of the electric motor, and the rotary shaft of the electric motor is connected with the back end and a front cover of the outer shell of the torque sensor through rolling bearings. The torque sensor comprises a friction wheel, a generator, a generator seat, a transmitter, a shaft clamp ring, a proving ring and the outer shell, wherein the generator seat, the shaft clamp ring and the proving ring are sequentially and fixedly connected to the rotary shaft of the electric motor from left to right in the outer shell, the generator is fixedly connected to the generator seat, the friction wheel is connected to a rotary shaft of the generator, and the outer circle of the friction wheel is in frictional contact with the inner wall of the outer shell; and the shaft clamp ring is fixedly connected with the transmitter through a transmitter connecting plate. In the invention, the electric motor and the torque sensor are combined together, a working torque is directly tested by utilizing the torque sensor, and therefore, the electric motor can not be influenced by the fluctuation of parameters comprising current, voltage, rotary speed and the like, thereby greatly improving testing precision.

Description

technical field [0001] The invention relates to an electric motor, especially an electric motor combining an electric motor and a torque sensor. Background technique [0002] Commonly used motors do not have torque sensors. See figure 1 , it is mainly composed of machine base 1, sealing sleeve 2, stator 3, rotor 4, end cover 5, bearing 6, and rotating shaft 7. Its working load (working torque) is usually based on various parameters such as current, voltage, and speed of the motor for indirect detection. Test accuracy is often affected by fluctuations in parameters such as current, voltage, and speed. Contents of the invention [0003] The present invention is to provide a motor with a torque sensor, which combines the motor and the torque sensor, and uses the torque sensor to directly test the working torque, so it will not be affected by fluctuations in parameters such as current, voltage, and rotational speed. And adopt stable uninterrupted power supply and signal em...
