Description
A kind of bidirectional circulatory driving decelerating electric machine belongs to mechanical field.
Existing reducing motor is combined motor and reductor, and making its output speed is through the rotating speed after slowing down, directly to be connected with working machine.General gear reduction unit, worm-gear speed reducer, planet-gear speed reducer or the cycloidal planetary gear speed reducer etc. of adopting of its reductor part.Single-stage or multi-stage speed-reducing form are arranged.For realizing various speed reducing ratio, generally all need adopt multi-stage speed-reducing.Promptly slow down through one or more levels and realize unidirectional transmission by a driving gear.Transmission progression is many, the transmission chain length.The reductor part is often big than motor section partial volume, Heavy Weight, complex structure.Be difficult to motor and reductor are made an integral body, generally they be associated in together and use with shaft coupling, very inconvenient.
The objective of the invention is to create a kind of bidirectional circulatory driving decelerating electric machine, to replace the deceleration device of existing reducing motor and existing reductor and motor apportion.No matter need which kind of output speed, all need not adopt multi-stage speed-reducing, only needing one-level to slow down can realize.Its reductor partial volume is very little, and architectural feature is a garden shape, and diameter and motor diameter are close, and length is about about 1/4th of motor length.The one-level deceleration can realize the arbitrary speed ratio between 1～∞.Simple and compact for structure, can in multiple machine driving, be used widely.To precision mechanical transmission and large speed ratio, high-power, the high pulling torque actuating unit is particularly suitable.
The objective of the invention is to realize by following measure.In reducing motor, on the output shaft of motor part two driving gears are housed, respectively along both direction through limited several gears.Engaged transmission goes up outputting power from another axle at last.Driving gear is meshed with a gear ring in the gear ring that has two ring gears through idler gear, and another driving gear passes through planetary gear and is meshed with another ring gear in this gear ring.Planetary connecting rod is output shaft.As long as the number of teeth of two driving gears and two ring gears is suitably selected, and correspondingly be equipped with idler gear and the planetary gear that satisfies the transmission meshing condition, can realize from 1 to the arbitrary transmission speed ratio between the infinity.
