Abstract

The test unit includes motor output shaft connected to a drive motor. Motor output shaft is connected to the transmission shaft. Electromagnetic brake (EB) is setup on the transmission shaft, and a fixed plate of EB is installed on base. Breaking part of EB is connected to the transmission shaft. Friction discs of EB are located between the fixed plate of EB and the breaking part. A push pressureplate is installed on the transmission shaft, which is connected to the power crankshaft. Crank matched to the push pressure plate is setup on the power crankshaft. Through coupling, the power crankshaft is connected to the rotating torque sensor; and through another coupling, the rotating torque sensor is connected to axis of the encoder. The encoder is installed on the axis of the encoder. The axis of the encoder is connected to the connection interface of device to be measured. Features are: high measuring accuracy, adjustable load, driving speed and moment based on need.

Description

(1) Technical field [0001] The invention relates to a torque testing device. (2) Background technology [0002] For occasions that require torque testing, a torque transmission device is required, including a mechanical interface connected to the device to be tested, and a power output shaft connected to the drive motor. For example, the Chinese patent No. is 200320110275.8, and the patent name is a utility model patent for a high-speed, high-torque transmission box for a co-rotating twin-screw extruder, which discloses a torque transmission box that is driven by a driving gear and a driven gear. For the existing torque testing device, there are defects: it cannot adapt to the occasion requiring high precision, cannot adjust the speed and torque of loading and driving, and cannot meet the wide range requirements of loading and driving for speed and torque. (3) Contents of the invention [0003] In order to overcome the low precision of the existing torque testing device a...
