Embodiment Construction

[0036] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0037] Such as figure 1 As shown, the torque sensor combined with the speed reducer of the present invention combines the speed reducer 100 and the torque sensor 101 without changing the original structure of the speed reducer, but only increases the length of the output shaft of the speed reducer for A torque sensor 101 is installed. Utilize the torque sensor 101 to directly measure the working torque. Since this test method uses the torque sensor to directly test the load, it will not be affected by other parameters, thereby greatly improving the test accuracy, and because the sensor is directly installed on the output shaft of the reducer, it does not affect the transmission efficiency, making effective Energy can be fully utilized.

[0038] Such as figure 2 As shown, the torque sensor combined with the speed reducer is equipped with a special t...

Abstract

The invention relates to a torque sensor combined with a reducer. The torque sensor comprises a reducer, an output shaft, an outer shell and an inner lining, wherein the sensor is arranged on the output shaft of the reducer; the outer shell is fixed with the outer shell of the reducer; a pair of rolling bearings is arranged between the outer shell and the inner lining; the inner lining is fixedlyconnected with the output shaft of the reducer; conductive copper rings are arranged at the places of the inner lining where the bearings are arranged, and an emitter is arranged in the middle; on the output shaft, a force measurement ring is arranged outside the inner lining; the outer shell is provided with a power converter; the inner lining is fixedly connected with the output shaft of the reducer through an adjusting bolt by a T-shaped tapered wedge; the force measurement ring consists of two semicircular annular structures and has a transverse H-shaped section; and two groups of torque measurement resistance strain gauges are adhered to the outer circular surface of the middle working section. The torque sensor is combined with the reducer and utilized to test the working torque directly without being influenced by other parameters so as to greatly improve the testing accuracy, not to affect the transmission efficiency and make full use of the effective energy source.

Description

technical field [0001] The invention relates to a torque sensor, especially a torque sensor for a speed reducer. Background technique [0002] Commonly used reducers do not have torque sensors. Its working load (working torque) can usually only be estimated or a torque sensor can be added to the transmission chain. The estimated value often has a large error, and adding a torque sensor will affect the space size of the entire transmission chain and affect the transmission efficiency. This is also not in line with modern energy saving requirements. Contents of the invention [0003] The present invention is to provide a torque sensor combined with the speed reducer, the torque sensor is combined with the speed reducer, and the torque sensor is used to directly test the working torque without being affected by other parameters, thereby greatly improving the test accuracy. At the same time, it does not affect the transmission efficiency, so that the effective energy can be...
