Abstract

The invention discloses a permanent magnet infinitely variable speed reducer which comprises a box (1), an input shaft (2), a transmission shaft (8) and an output shaft (9). The tail end of the input shaft (2) is provided with a conductor rotor (7) which is in rotation with the input shaft (2). The corresponding portion of the conductor rotor (7) is provided with a permanent magnet motor (5) which is arranged opposite to the conductor rotor (7). The permanent magnet motor (5) is connected with one end of the transmission shaft (8) and in rotation with transmission shaft (8). The other end of the transmission shaft (8) is provided with a driving gear (6). The driving gear (6) is engaged with a driven gear (10) installed on the output shaft (9). The axial sliding of the permanent magnet motor (5) along the transmission shaft (8) is enabled through an adjusting mechanism so as to change the torque transferred between the permanent magnet motor (5) and the conductor rotor (7). According to the invention, the infinitely variable speed function and the speed-reducing and torque-increasing function can be realized, and advantages of compact structure, convenient installation, high transmission efficiency and long service life can be realized.

Description

technical field [0001] The invention relates to the technical field of transmissions and reducers, in particular to a permanent magnet continuously variable speed reducer. 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, and the mechanical gear transmission generally has a stepped speed regulation. With the increase o...
