Abstract
The invention discloses a duplex internal tooth speed reducer, that is, a speed reducer has a key part of a duplex internal gear. The duplex internal tooth speed reducer has a basic structure principle: two levels of gears of a sun wheel of a second-level gear are used for respectively driving a star wheel and a planet wheel; then, the duplex internal gear is used for linking the star wheel with the planet wheel to enable the planet wheel to generate the differential; and as the planet wheel is mounted on a planet carrier, the planet carrier finishes the final speed reduction output.
Description
Art
The present invention relates to a kind of mechanical gearing speed reducer
Background technique
Existing speed reducer is of a great variety, differ and lift, but all respectively having its narrow limitation, all there is different weakness, some velocity ratios are limited, some mechanical efficiency are not high, and what have is not suitable for high power transmission, some complex process processing difficulties, installation inconvenience also had etc., therefore invent a kind of advantage collecting existing speed reducer, overcome the speed reducer of the brand new class of its deficiency, become technical development in the urgent need to; This speed reducer should be compact structure, wide cut speed ratio, efficient driving, technique convenience.
Summary of the invention
Fig. 1 is structure principle chart of the present invention;
First with Fig. 1, technological scheme of the present invention is described: on ' fixed star frame ' part 1, ' sun wheel ' part 3 and ' turriform sun gear ' part 4 are installed, first order gear in ' turriform sun gear ' part 4 is meshed with ' sun wheel ' part 3, the second level gear of ' turriform sun gear ' part 4 is then meshed with ' planet wheel ' part 7, and ' planet wheel ' part 7 is installed on ' planet carrier ' part 8.' sun wheel ' part 3 ' planet wheel ' part 7 is meshed with two level internal tooths of ' duplex internal gear ' part 6 again simultaneously respectively.' needle roller ' part 2, ' ball ' part 5 and ' ball ' part 9 form the rolling support to system.
The working principle of duplex inside-engaged gear speed reducer is: ' turriform sun gear ' is connected with the line shaft of mechanical system as input shaft, the gear that two levels of this ' turriform sun gear ' are secondary drives ' sun wheel ' and ' planet wheel ' respectively, the rotation of ' sun wheel ' has simultaneously driven again ' duplex internal gear ' and ' duplex internal gear ' also has transmission to occur simultaneously with ' planet wheel ', form the differential gearing to ' planet wheel ', so planet wheel creates the revolution around sun gear, this revolution motion of planet wheel has driven the rotation of ' planet carrier ' as output shaft, thus complete whole gearing down.
The constrained input axle concentric of ' duplex inside-engaged gear speed reducer ' of the present invention, therefore installation easy to use, and also the axial direction of ' duplex inside-engaged gear speed reducer ' is obviously compact, and reasonable integral structure is light and handy.Because this speed reducer adopts all gear structure, not only manufacturability is fabulous, and can ensure high transmission efficiency.Particularly ' duplex inside-engaged gear speed reducer ' of the present invention has the transmission speed ratio of pole wide range, be not difficult to find out from shown Fig. 1, two level gear joint garden equal diameters of ' if turriform sun gear ', simultaneously sun wheel ' also equal with the pitch diameter of ' planet wheel ' time, then planet carrier and fixed star frame synchronous, staticly not to rotate, that is transmission speed ratio is now infinitely great.When above-mentioned two kinds of pitch diameters produce difference, ' planet carrier ' will rotate, and the different less rotation of difference diameter of this Liang Jie garden is slower, speed ratio is larger, and this Liang Jie garden larger rotation of diameter difference is faster, speed ratio is less.
Claims (1)
1. ' the turriform sun gear ' that be made up of two sections of gears is the power input part of ' duplex inside-engaged gear speed reducer ', two sections of gears of ' turriform sun gear ' drive ' sun wheel ' and ' planet wheel ' respectively, because the running shaft of ' sun wheel ' is fixed on ' the fixed star frame ' that can not move, so ' sun wheel ' can only from then can not revolve round the sun, and the running shaft of ' planet wheel ' is on rotary ' planet carrier ', therefore ' planet wheel ' both can also can revolve round the sun in rotation, that engages with ' sun wheel ' and ' planet wheel ' also has ' duplex internal gear ' in order to both to be linked simultaneously, ' planet wheel ' receives the transmission from ' turriform sun gear ' and ' duplex internal gear ' simultaneously, therefore produce differential, create not only rotation but also the compound motion revolved round the sun, that revolution motion has just driven the rotation of ' planet carrier ', complete the retarded motion of ' duplex inside-engaged gear speed reducer '.
