The utility model solves it and wants the technical scheme of technical solution problem to be:
A kind of reducing motor that is specially adapted to electro-tricycle, by the tubular motor that comprises end cap and central gear, with comprise housing, with the pinion frame power output shaft of one each other, 3 mutually between 120 ° of planetary gears of arranging and being dynamically connected by minor axis with pinion frame and in interior, establish the planetary gear speed-reduction transmission device with the intermeshing ring gear of planetary gear and form; Central gear and the static connection of cartridge type motor shaft, and be meshed with planetary gear; Power output shaft and housing axis hole are movingly; Ring gear is located between housing and the end cap, and fixedly connected by the bolt three, and its innovative point is that described planetary gear and ring gear are molded high-strength engineering plastic helical gears, and central gear is the steel helical gear.
Can understand by above given technical scheme, the utility model is because its described ring gear and planetary gear adopt the high-strength engineering plastic helical gear, central gear adopts the steel helical gear, thereby not only effectively reduce operating noise, improved service behaviour, and its power transfer torque and functional reliability, all obtained obvious enhancing, thereby realized the purpose of this utility model, and because ring gear and planetary one-off pattern are molded, and reduced production cost of the present utility model relatively, effectively improved cost performance.
Further innovative point of the present utility model is:
Described planetary gear and ring gear are the composite molded high-strength engineering plastic helical gears of high-strength engineering plastic and short glass fiber.Its purpose is further to improve the mechanical performance of described plastic beveled wheel.
The angle α of the denticle of described central gear, planetary gear and ring gear and its center line is in 10 °～17 ° scopes.Its purpose is effectively to guarantee described helical gear operate as normal.
Described ring gear is fixedlyed connected with end cap and housing, is the both sides cylindrical by ring gear, the round concentric fit of interior step round with the interior step of end cap respectively and housing, and the three is fixedly connected by bolt.With further raising mechanical performance of the present utility model.
Described power output shaft and housing axis hole are by 2 ball bearings arranged side by side movingly movingly.This operate as normal for power output shaft has positive effect.
Characteristics such as after technique scheme was implemented, the moment of torsion that the utility model had was relatively large, and stable working is reliable, and operating noise is low, and production cost is relatively low are self-evident.
