Abstract

The invention comprises a motor output shaft, which is connected with a driving motor and a small clutch shaft. On the small clutch shaft is mounted a first electromagnetic clutch, whose armature is firm-jointed with the small clutch shaft. The armature of the first electromagnetic clutch is firm-jointed with a light load drive synchronous belt wheel and connected with a connecting sleeve via a spline. The small clutch shaft is connected with a speed reducer input shaft through a second coupling and the output shaft of the speed reducer is firm-jointed with a heavy load drive synchronous belt wheel and is mounted a second electromagnetic clutch. The armature of the second electromagnetic clutch is firm-jointed with the heavy load driven synchronous belt wheel and is connected with a connecting sleeve via a spline.

Description

(1) Technical field [0001] The invention relates to a two-speed and two-torque transmission device. (2) Background technology [0002] For occasions that require high-precision testing of torque and speed, 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. The existing defects are: it cannot adapt to the occasions requiring high precision, cannot adjust the constant speed and constant torque of loading and driving, and cannot meet the wide range requirements of loading and driving for speed and torque at the same time. For example, the rated power of an AC servo motor is as high as ...
