Abstract
The utility model relates to a toothed planet-gear speed reducer whose driving end housing 4 is fixedly connected with a driven end housing 11 by a screw bolt. An annular gear A is fixed in the driving housing 4 and an output shaft 13 with an annular gear B is installed in the driven end housing 11 through a bearing 10. One end of an eccentric shaft 9 is fixed in the driving end housing 4 through a bearing 2 and the other end of the eccentric shaft is fixed in a bearing block on the left end of the output shaft 13 through a bearing 8. A connected planet wheel c and a connected planet wheel d are installed on the eccentric shaft 9, and the planet wheel c is engaged with the planet wheel d which is engaged with the annular gear b. The numbers of teeth difference of the two pairs of mutually engaged planet wheels and the annular gear are equal and are one to two teeth in general. The utility model has the advantages of large transmission ratio, few parts, compact structure, small size and convenient installation.
Description
The utility model relates to speed reducer, especially a kind of fewer differential teeth planetary wheel decelerator.
In mechanical transmission, need various speed change gears that high rotating speed is become the slow-speed of revolution, or the slow-speed of revolution is become high rotating speed.Common mechanical mostly is by high rotating speed and becomes the slow-speed of revolution.Traditional reducer structure more complicated by high rotating speed step-down rotating speed, volume is big, weight is big, and transmission efficiency is lower, and especially the retarder of big retarding ratio is all the more so.
The purpose of this utility model provides that a kind of reduction speed ratio is big, volume is little, in light weight, transmission efficiency is high, transmission power is big fewer differential teeth planetary wheel decelerator, solves in the mechanical transmission big retarding than the existing the problems referred to above of speed reducer.
The utility model is achieved in that the fewer differential teeth planetary wheel decelerator comprises drive end housing, driven end housing, eccentric shaft, planet wheel, ring gear and output shaft.Ring gear A is housed in the drive end housing.The left end of eccentric shaft is contained in the drive end housing by bearing.By bearing a double-planetary gear is housed on the eccentric shaft.The double-planetary gear left side is planet wheel C, and the right side is planet wheel D.The driven end housing links to each other with the drive end housing by bolt.One output shaft by Bearing Installation in the driven end housing.The output shaft left end is shaped on ring gear B.The right-hand member of eccentric shaft by bearing fixing in the bearing support of output shaft left end.The planet wheel C of double-planetary gear and ring gear A engagement, the planet wheel D of double-planetary gear and ring gear B engagement.The planet wheel C of double-planetary gear and the number of teeth of ring gear A have a difference; The number of teeth of planet wheel D and ring gear B also has a difference.Planet wheel C equates with the number of teeth difference of ring gear B with planet wheel D with the number of teeth difference of ring gear A.The number of teeth difference of the number of teeth difference of planet wheel C and ring gear A and planet wheel D and ring gear B is preferably the 1-2 tooth.
Eccentric shaft left end and drive end housing be connected and right-hand member all adopts single row ball bearing with being connected of output shaft.Eccentric shaft and double-planetary gear and output shaft are connected with the driven end housing, all adopt double-row bearing.
During use, the drive end housing is connected with motor with bolt by bolt hole, motor shaft inserts in the spindle hole of eccentric shaft.The driven end housing is connected with bolt and the machinery that is driven by bolt hole, and output shaft links to each other with the transmission shaft of machinery.
The utility model has the advantages that: 1. slewing range is big, and gear ratio can be from more than the several times to ten thousand times; 2. compact structure, part is few, weight only is the 1/4-1/10 of other retarders; 3. input/output terminal is on same axis, and the method for employing dish structure is connected with mechanical part with power section, and installation easy for installation, vertical, horizontal all can; 4. part is few, and processing, assembly precision easily improve, stable drive, and noise is little; 5. driving torque is big, and ratio is constant.The utility model can replace all kinds retarder, is suitable for small-sized, accurate instrument, equipment use especially, as instrument, medical equipment, food machinery etc.
Accompanying drawing is a structural drawing of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing: toothed planet-gear speed reducer comprises drive end housing 4, driven end housing 11, ring gear A, planetary gear C, planetary gear D, eccentric shaft 9 and output shaft 13. Ring gear A is connected in the drive end housing 4. Output shaft 13 left ends are shaped with ring gear B. Eccentric shaft 9 left ends are fixed in the drive end housing 4 by bearing 2, and right-hand member is fixed on the left end of output shaft 13 by bearing 8. Link to each other with planetary gear C, planetary gear D by double-row bearing on the eccentric shaft 9. Planetary gear C, planetary gear D are the disjunctor gear. Output shaft 13 is bearing on the driven end housing 11 by double-row bearing 10. Planetary gear C and internal gear A engagement, planetary gear D and internal gear B engagement. Drive end housing 4 links to each other by screw hole 5 with driven end housing 11 usefulness bolts. The left and right sides of double-row bearing is provided with hole back-up ring 7 and shaft block ring 15 on the eccentric shaft 9. Be equipped with oil sealing 12 with eccentric shaft 9 and output shaft 13 matching parts in drive end housing 4 and the driven end housing 11. The tooth difference of planetary gear C, ring gear A equates with the tooth difference of planetary gear D, ring gear B. Be preferably the 1-2 tooth.
During use, drive end housing 4 is connected by bolt hole 3 usefulness bolts with motor, and electric machine main shaft engages with the spindle hole 1 of eccentric shaft 9. Driven end housing 11 is connected with bolt by bolt hole 14 and the machinery that is driven, and output shaft 13 links to each other with the power transmission shaft that is driven machinery.
Example 1: an a kind of differential teeth planetary wheel decelerator, m=1, velocity ratio i=2916 doubly weighs 3 kilograms, is loaded on the small tool leading screw end of c650 lathe, has realized the with nothing left cutter automatic feed of lathe, main shaft revolution feed 0.04mm.
Example 2: a kind of two teeth difference planet wheel decelerator, m=2, velocity ratio i=36 doubly weighs 4 kilograms, is loaded on Z
32Radial drill founds the leading screw end, orders about heavy 84 kilograms cross bearer and pumps, and works well.
