Abstract

The invention discloses a flux concentration Halbach array-type permanent magnet face gear set for quadrature axis transmission, and relates to the field of the electromechanical transmission. In order to solve the problems that the structure of the current permanent magnet face gear and bevel gear for the quadrature axis transmission is complicated, the manufacture and assembly are difficult, the flux concentration Halbach array-type permanent magnet face gear set for the quadrature axis transmission comprises two wheels, and two wheels are the magnetic gears. Two wheels are a cylinder gear and a face gear respectively. The face gear is horizontally installed, and the cylinder gear is installed above the face gear. The central lines of the axles of the cylinder gear and the face gear are orthogonal. An air clearance is kept between the cylinder gear and the face gear. While one gear is used as a driving gear, and the other gear is used as a driven gear. The driving gear drives the driven gear to be rotated through the magnetic force. The gear set has the characteristics of simple and compact structure, and convenient assembly, and is suitable for the occasions where the noise, the cleanliness and reliability requirements are higher and two axis systems are mutually isolated.

Description

technical field [0001] The invention relates to the field of electromechanical transmission, in particular to a magnetic flux concentration-Halbach array permanent magnet face gear set for orthogonal shaft transmission. Background technique [0002] At present, bevel gears and face gears are mostly used in the transmission of orthogonal shafts. The shape of the tooth surface of the bevel gear is complex, and it is difficult to process and manufacture. The parameters of different brands of bevel gears are also different, and in the production process, they are usually manufactured in pairs, which causes great troubles to the processing, repair and maintenance of bevel gears. Since the tool size required for processing face gears is the same as the actual meshing cylindrical gear, the number of tools required to process face gears of different sizes and parameters is relatively large, and the processing cost is high; There is a sharp angle phenomenon, so the tooth width canno...
