Abstract

A Halbach array permanent magnet face gear set for orthogonal shaft drive belongs to the field of electromechanical drive. The invention aims to solve the problem that the torque transmitted by permanent magnet face gears and bevel gears currently used for orthogonal shaft drive is limited. According to the invention, the Halbach array permanent magnet face gear set for orthogonal shaft drive consists of two wheels. The two wheels are both magnetic gears, which are a cylindrical wheel and a face wheel. The face wheel is arranged horizontally. The cylindrical wheel is arranged above the face wheel. Shaft center lines of the cylindrical wheel and the face wheel are orthogonal. An air gap is left between the cylindrical wheel and the face wheel. When one of the wheels is a driving wheel, the other wheel is a driven wheel, and the driving wheel drives the driven wheel by magnetic force. The invention uses permanent magnets of the Habach array to produce a stronger air gap magnetic flux, and the torque that can be transmitted is greater.

Description

technical field [0001] The invention relates to the field of electromechanical transmission, in particular to a 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 cannot be designed too long, and ...
