Abstract

The invention discloses an integrated permanent magnet variable speed reducer which comprises a box (1), an adjuster (6), an input shaft (2) and an output shaft (8). The input shaft (2) is provided with a cylindrical high-speed permanent magnet motor (3) which is in synchronous rotation with the input shaft (2). The output shaft (8) is provided with a cylindrical low-speed permanent magnet motor (7) which is arranged correspondingly to the high-speed permanent magnet motor (3) and in synchronous rotation with the output shaft (8). The high-speed permanent magnet motor (3) is located in the inner cavity of the low-speed permanent magnet motor (7). A cylindrical modulation iron core (4) is arranged in the radial gap between the low-speed permanent magnet motor (7) and the high-speed permanent magnet motor (3). The modulation iron core (4) is extended into the radial gap between the low-speed permanent magnet motor (7) and the high-speed permanent magnet motor (3) or leaves from the radial gap between the low-speed permanent magnet motor (7) and the high-speed permanent magnet motor (3) through the driving of the adjuster (6). According to the invention, the infinitely variable speed function and the speed-reducing and torque-increasing function can be realized, the oil leakage problem does not exist, and advantages of energy conservation and environment protection, compact structure and high transmission efficiency can be realized.

Description

technical field [0001] The invention relates to the technical field of transmissions and reducers, in particular to an integrated permanent magnet variable speed reducer capable of realizing stepless speed change, deceleration and torque increase without lubricating oil. Background technique [0002] A transmission is a device that can change the transmission ratio or speed of its output shaft and input shaft; the reducer plays a role in matching the speed and transmitting torque between the prime mover and the working machine or the actuator; the application of the transmission and the reducer in modern machinery is It is extremely extensive, but the transmission and the reducer are basically separate mechanical devices, and there are few speed reduction devices that integrate the two. When the existing mechanical gear transmission is used, the prime mover is rigidly connected to the working machine or the actuator, and a clutch needs to be used in the speed change process,...
