Abstract
The utility model relates to a single-stage super low speed planet gear electric reducer, which is connected to a sun gear in the spindle of a motor. Three equidistant planetary gears are fixed and meshed between an internal gear and the sun gear mesh, a planetary gear is connected to more than an idle gear which has one gear more than the planetary gear, the output internal gear which has one gear less than the fixed gear is meshed with the three idle gears, and the super low speed output shaft is connected to the output internal gear. When the motor is turned at high speed, the output gear spins in a super low speed under the effect of the difference of the planetary gear teeth. The utility model has a simple structure, high transmission efficiency and large transmission torque, which can be applied to industry, agriculture, construction, water conservancy and other areas.
Description
Affiliated field
The utility model belongs to mechanical field, relates to a kind of structure of single-stage Ultra-Low Speed planetary pinion electric reducer.
Background technique
At present, domestic electric reducer kind is a lot, but the general volume of these speed reducers is all bigger, and transmission progression is many, the driving mechanism complexity, and velocity ratio is about about 1: 200.That releases on the market in recent years has a kind of speed reducer that utilizes the harmonic wave principle to make, though its volume is the same with motor big, moment of torsion is little, efficient is low.
Technology contents
The purpose of this utility model is: design a kind of single-stage Ultra-Low Speed planetary pinion motor reducer, its output shaft per minute rotating speed can be on 5 right sides of turning left, and moment of torsion is big, transmission efficiency is high.
The purpose of this utility model is achieved in that on the main shaft of motor and connects sun gear, garden Zhou Shangsan only is equidistant planetary pinion and sun gear engagement outside sun gear, on three planetary pinions, respectively be connected with idler more than planetary pinion one tooth, fixed annulus is positioned at garden, three planetary pinion outsides on week, and mesh with planetary pinion, on garden, the outside week of three idlers, there is an internal tooth to be less than output gear and three carrier gear engagements of fixed annulus one tooth, the low speed output shaft is housed on the output gear.
When the electric machine main shaft high speed rotating, the sun gear that is contained on the electric machine main shaft rotates with speed, three the planetary pinion rotations of drive between fixed annulus and sun gear, three also rotations synchronously of idler that planetary pinion connects more than the one tooth, driving position output inner gear thereon rotates, under the effect of tooth difference, the output shaft on the output inner gear will rotate slowly, realize the purpose of its single-stage Ultra-Low Speed work.

Among the figure: 1, motor 2, reducing gear 3, output shaft 4, electric machine main shaft 5, support 6, planetary pinion 7, fixed gear 8, output inner gear 9, idler 10, sun gear
Implementation methods
Reducing gear and motor are integrated, and the low speed output shaft is positioned at the one or both sides of electric machine main shaft.
Main shaft 4 on the motor 1 connects sun gear 10, on sun gear 10 outer peripheral teeth, there are three to be equidistant planetary pinion 6 and sun gear 10 engagements, there is fixed annulus to be engaged with in the outside of three planetary pinions 6, respectively be connected with carrier gear 9 on three planetary pinions 6 more than planetary pinion 6 one teeth, have the number of teeth in to be less than output inner gear 8 and three carrier gears 9 engagements of fixed annulus 7 one teeth on garden, the outside week of three carrier gears 9, output shaft 3 is connected with output inner gear 8 axial restraints.
After motor is connected power supply during main shaft 4 high speed rotating, the sun gear 10 that is contained on the electric machine main shaft 4 rotates with speed, three planetary pinions 6 rotations of drive between fixed annulus 7 and sun gear 10, three planetary pinions 6 connect respectively more than the fast together rotation of the carrier gear 9 of one tooth, make and be positioned at three output inner gears 8 on the carrier gear 9 and slowly rotate, under the effect of tooth difference, three carrier gears 9 revolve and turn around, output inner gear 8 rotates a tooth, realizes the purpose of its one pole Ultra-Low Speed rotation.
The number of teeth of making the speed reducer middle gear generally requires design with difference, each number of teeth that output shaft per minute 5 changes: sun gear 10 is 13 teeth, planetary pinion 6 is 26 teeth, fixed annulus 7 is 67 teeth, carrier gear 8 is 27 teeth, output inner gear is 66 teeth, and the design of the number of teeth of various rotating speeds is different because of the modulus of the power of motor, rotating speed, gear etc.
The utility model single-stage is slowed down, and the ingenious deceleration by a tooth difference has realized the output of Ultra-Low Speed.This Ultralow speed motor can be widely used in numerous areas such as building, water conservancy, chemical industry, electronics, light industry, weaving, agricultural.
