CN2646945Y - A highly effective circular arc tooth motor speed reducer - Google Patents

Abstract

A highly effective circular arc tooth motor speed reducer is provided with a circular arc tooth speed reducing mechanism on one side or two sides of a motor. A driving rotation gear is connected on a main shaft of the circular arc tooth speed reducing mechanism. A driven transmission gear is joggled with the driving rotation gear. An eccentric shaft is positioned on the driven gear. Two groups of double-linkage gear are arranged on the eccentric shaft, wherein, one group is joggled with a fixed inner gear, while the other group is joggled with an output inner gear. The speed reduction by the circular arc tooth can realized a super low speed rotation of the output shaft from 4 to 5 per minute.

Description

A kind of efficient circle-arc tooth motor reducer

Affiliated field

The utility model belongs to mechanical field, is specifically related to a kind of structure of efficient circle-arc tooth motor reducer.

Background technology

At present, the circle-arc tooth reductor volume on the market is big, torque is little, noise is big, power output is low, and range of application is little, does not still have a kind of high efficiency circle-arc tooth motor reducer to come into the market at present.

Technical scheme

The purpose of this utility model is: design a kind of efficient circle-arc tooth motor reducer, to overcome the defective that present various forms reductor exists.

The purpose of this utility model is achieved in that in the one or both sides of motor and connects the circle-arc tooth reducing gear, connect initiatively travelling gear on the power shaft in the circle-arc tooth reducing gear, one group of passive transmitting gear and its engagement, be connected with eccentric shaft on this group passive transmitting gear, two groups of duplicate gears are positioned on the eccentric shaft, be connected with output inner gear on the output shaft, output inner gear and wherein one group of duplicate gear engagement.

When motor energized high speed rotating, the power shaft that motor output shaft drives reducing gear rotates, the active travelling gear that is connected with power shaft rotates, at this moment one group of passive transmitting gear with its engagement rotates, and by being connected with eccentric shaft thereon, two groups of duplicate gears are under the effect of eccentric shaft, respectively with fixed annulus and output inner gear engagement, last power is exported through output shaft, changes the modulus of rotating mechanism gear, can realize that the Ultra-Low Speed that per minute 4～5 changes rotates.

Among the figure: 1, power shaft 2, active travelling gear 3,4,5,6 one groups of duplicate gears of passive transmitting gear, 7,8 another group duplicate gears 9, output inner gear 10, eccentric shaft 11, fixed annulus 12, output shaft 13, motor 14, reducing gear

Implementation method

Circle-arc tooth reducing gear 14 is equipped with in the one or both sides of motor 13, the main shaft of motor 13 connects the power shaft 1 in the reducing gear 14, initiatively travelling gear 2 is connected with power shaft 1, one group of passive transmitting gear 3,4 and initiatively travelling gear 2 engagements, be connected with eccentric shaft 10 on this group driven gear 3,4, one group of duplex internal gear 5,6 is enclosed within on the eccentric shaft 10 and with fixed annulus 11 takes turns to mesh, another group duplex internal gear 7,8 also is enclosed within on the eccentric shaft 10 and with output inner gear 9 and meshes, and axle shaft 12 connects output inner gears.

When motor 13 energized main shaft high speed rotating, because motor 13 main shafts connect the power shaft 1 in the reducing gear 14, make power shaft 1 high speed rotating and drive initiatively travelling gear 2 rotations, the one group of passive transmitting gear 3 that is engaged with, 4 rotate thereupon, eccentric shaft 10 on it also rotates thereupon, because one group of duplicate gear 5,6 are enclosed within on the eccentric shaft 10, so duplicate gear 5,6 take turns under the effect of eccentric shaft and fixed annulus 11 engagements, another organizes duplicate gear 7,8 take turns under the effect of eccentric shaft 10 and output inner gear 9 engagements, output inner gear 9 is slowly rotated, because output shaft 12 connects output inner gear 9, so output shaft 12 rotates slowly.The module that changes in the reducing gear 14 just can obtain the different low speed outputs that require.For example: adopt the main shaft output of 0.75KW motor after slowing down to reach 4.5 rev/mins, torque reaches 900NM, noise is less than 60db, temperature rise is no more than 70 ° can satisfy weaving, machinery, grain processing, medical treatment, building, lifting, transportation, mine, metallurgy, petrochemical industry, electronic equipment, the deceleration requirement of multiple occasions such as rural area green house of vegetables roller shutter.
