Abstract

The invention relates to a magnetoresistive magnetic surface gear set for orthogonal shaft transmission and belongs to the electromechanical transmission field. The objective of the invention is to solve the problems of high cost, complex structure and difficulty in manufacture and assembly of currently-used permanent magnet face gears and bevel gears used for orthogonal shaft transmission. The magnetoresistive magnetic surface gear set for the orthogonal shaft transmission of the present invention comprises two wheels, namely, a cylindrical wheel and a planar wheel; the planar wheel is arranged horizontally; the cylindrical wheel is arranged above the planar wheel; the center lines of the wheel shafts of the cylindrical wheel and the planar wheel are orthogonal to each other; an air gap is left between the cylindrical wheel and the planar wheel; when one of the cylindrical wheel and the planar wheel is a driving wheel, the other wheel is a driven wheel; the driving wheel drives the driven wheel to rotate through a magnetoresistive force; and when one of the cylindrical wheel and the planar wheel is a permanent magnet wheel, the other wheel is a mechanical wheel. According to the magnetoresistive magnetic surface gear set of the invention, the cylindrical wheel and the planar wheel do not mechanically contact with each other directly, and therefore, the gear set has the advantages of no wear, no noises, high transmission efficiency, high reliability, maintenance-free performance, overload protection and so on.

Description

technical field [0001] The invention relates to the field of electromechanical transmission, in particular to a reluctance magnetic surface 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 the tran...
