Abstract

The invention provides a permanent magnet gear speed change device which comprises an outer supporting bearing and an inner supporting bearing. The outer supporting bearing is arranged on a magnet adjusting ring framework in a sleeving mode, and the outer supporting bearing is located between an outer magnet ring cylinder and the magnet adjusting ring framework in the radial direction of an inner magnet ring and makes contact with the outer magnet ring cylinder and the magnet adjusting ring framework. The inner supporting bearing is located between the inner magnetic ring cylinder and the output shaft in the radial direction of the inner magnetic ring and makes contact with each of the inner magnetic ring cylinder and the output shaft. According to the permanent magnet gear speed change device, through the combined action of the inner supporting bearing and the outer supporting bearing, the outer supporting bearing plays a role in supporting the magnetic adjusting ring framework, the inner supporting bearing plays a role in supporting the output shaft, and due to the fact that the magnetic adjusting ring and the output shaft rotate together, under the combined action of the outer supporting bearing and the inner supporting bearing, stable rotation of the magnetic adjusting ring is achieved. Therefore, the permanent magnet gear speed change device provided by the embodiment of the invention has the advantage of good structural stability.

Description

technical field [0001] The present invention relates to the technical field of permanent magnet gears, and more particularly, to a magnetism adjusting ring and a permanent magnet gear speed change device having the magnetism adjusting ring. Background technique [0002] The permanent magnet gear transmission is widely used in the transmission field. Since there is no physical contact between the driving wheel and the driven wheel, but the force of the permanent magnet magnetic field is used for transmission, the permanent magnet gear transmission is an ideal choice for the transmission field. It has the advantages of good performance and high reliability. The permanent magnet speed changer consists of three main parts: the inner magnetic ring, the outer magnetic ring and the magnetic adjusting ring. One of the parts is fixed, and the other two parts are used as movers to realize the ratio function of speed and power. In the related art, the magnetic ring is usually a cantil...
