Abstract

The invention discloses a magnetic flow-concentrating permanent-magnet planar gear set for quadrature axis transfer motion, and relates to the field of mechanical and electrical transmission. The magnetic flow-concentrating permanent-magnet planar gear set aims at solving the problems that in the permanent-magnet planar gears and bevel gears for quadrature axis transfer motion, the use level of permanent magnets of is high and cost is high. The magnetic flow-concentrating permanent-magnet planar gear set comprises two gears which both are magnetic gears, and respectively are a cylinder gear and a plane gear, wherein the plane gear is arranged horizontally and the cylinder gear is arranged above the plane gear, and the axletree center line of the cylinder gear is orthometric with that of the plane gear, an air gap is formed between the cylinder gear and the plane gear; while one of the gears is a driving gear, the other one of the gears is a driven gear, the driving gear drives the driven gear to rotate through magnetic forces. According to the magnetic flow-concentrating permanent-magnet planar gear set, as gap flux density is produced by means of concentrating magnetic flow, the use level of the permanent magnets is reduced by a large margin, and cost is reduced.

Description

technical field [0001] The invention relates to the field of electromechanical transmission, in particular to a magnetic flux concentrated permanent magnet 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 designe...
