The beneficial effects of the utility model are: this utility model can position the row at support planetary gear two ends by being provided with Star-wheel positioning element, location supports the two ends of planetary gear simultaneously, makes planetary gear two ends uniform stressed, strengthens the carrying of planetary gear Ability and service life, and can prevent planet round from flying or landing in the case of faulty operation.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is this utility model internal structural map.
Detailed description of the invention
Planet-gear speed reducer as shown in Figure 1, including the housing 1 of hollow, is provided with the speed reducer output shaft of concentric in housing 1 3, sun gear 4, elastic ring gear 6, if being additionally provided with three planetary gears 5 and dry bearing in housing 1.Speed reducer output shaft 3 passes through Two angular contact ball bearings are rotationally connected with housing 1, and reductor input axocoel 2 is processed in sun gear 4 rear end, and sun gear 4 is anterior Being processed into gear shaft, gear shaft front end is rotationally connected with speed reducer output shaft 3 by a bearing, by one in the middle part of sun gear 4 Individual bearing is rotatably connected on housing 1, and gear shaft and three planetary gears 5 of sun gear 4 front end are meshed, three planetary gears 5 points Not with elastic ring gear 6 internal messing.Speed reducer output shaft 3 rear end connects three planetary gear positioning elements, and each planetary gear positions Parts respectively with a planetary gear phase configuration, each planetary gear positioning element positions the two ends of corresponding row star-wheel and respectively by planet In wheel 5 is limited in.By planetary gear positioning element, the effect that location supports is played at planetary gear 5 two ends, make planetary gear two ends equal Even stress, strengthens bearing capacity and the service life of planetary gear, and can prevent planet in the case of faulty operation Round flies or landing.
It is further preferred that planetary gear positioning element includes prelocalization parts 7 and the location planet of home row star-wheel front end The rear positioning element 8 of wheel rear end, rear positioning element 8 is connected with housing 1 by bearing, prelocalization parts 7 and rear positioning element 8 it Between be provided with a bearing pin 9, planetary gear 5 is assemblied on bearing pin 9, completes to prop up the location at planetary gear 5 two ends by above-mentioned structure Support.
It is further preferred that in reductor installation process, by adjusting elastic ring gear 6, planetary gear 5 and sun gear Centre-to-centre spacing so that elastic ring gear 6 coordinates with planetary gear 5 zero sideshake or minimum sideshake cooperation, and planetary gear 5 and sun gear 4 zero sideshakes engagements coordinate, zero sideshake coordinates or minimum sideshake coordinate can reduce when gear pair turns to hysterisis error and Turn to brought impact.
It is further preferred that elastic ring gear 6 is fixedly connected on housing 1.
It is further preferred that elastic ring gear is made up of elastic material, including high performance alloys steel or engineering plastics, passing When passing motion, the eccentric error caused because of Gear Processing radial error, planetary gear distribution error, elastic ring gear 6 carry out Eliminate.
The effect of angular contact ball bearing: speed reducer output shaft 3 uses two precision corner contact ball bearings to be rotatably connected on shell Internal, owing to having certain pressure, it is ensured that bearing play when reductor reaches temperature peak is zero.
The operation principle of the present embodiment:
During work, sun gear, as drivewheel, engages with planetary gear 5, drives planetary gear 5 rotation, in planetary gear 5 and elasticity Gear ring 6 engages, and produces revolution, and elastic ring gear is fixed, and constitutes one reducing gear, the velocity of rotation of planetary gear positioning element and The revolution speed of planetary gear 5 is identical, thus drives speed reducer output shaft 3 to realize torque drive and slowing effect.
Certainly, the invention is not limited to above-mentioned embodiment, and those of ordinary skill in the art are without prejudice to this Also can make equivalent variations or replacement on the premise of utility model spirit, modification or the replacement of these equivalents are all contained in the application In claim limited range.
