Abstract
Two planetary gear reducer machine floating positioning mechanism, including two sets of planetary gear mechanisms, two sets of planetary gear establishments of institution are on a sun gear shaft, the sun gear and the sun gear shaft fixed connection of two sets of planetary gear mechanisms, the ring gear of two sets of planetary gear mechanisms passes through crossbeam fixed connection, the planetary gear support of two sets of planetary gear mechanisms each other is corresponding mounting or moving part, both ends respectively and set up a location spring between the crossbeam about the planetary gear support of two sets of planetary gear mechanisms, location spring one end is fixed on the fixing base of crossbeam, the location spring other end is fixed on corresponding planetary gear support. The utility model discloses a set up the location spring that floats from top to bottom at the planetary gear of two sets of planetary gear mechanisms support, avoided planetary gear support and adjacent planetary gear or sun gear to take place to wipe to bump, have simple structure, move advantage stable and long service life.
Description
Technical field
The utility model relates to transmission technology field, is specifically related to a kind of dual planetary gear speed reducer floating positioning device.
Background technique
At present, the retarder that reduction speed ratio is large has planet-cycloid reducer, RV retarder, harmonic speed reducer, and planet-cycloid reducer assembling is complicated, and identical gear ratio volume is large.RV retarder also more complicated.The flexbile gear restricted lifetime of harmonic speed reducer, not shock-resistant.Dual planetary gear speed reducer can realize wide gear ratio by two groups of planetary gears, but two planetary gear carriers fixed block or movable part each other in speed-change process, the speed change initial stage easily touches with adjacent planetary pinion or sun gear generation wiping as driven planetary gear carrier, as do not adjusted in time, can cause damage to transmission case assembly, the normal table affecting gearbox runs.
Model utility content
The utility model provides a kind of dual planetary gear speed reducer floating positioning device, wipes the problem of touching and affecting and running with the driven planetary gear carrier and adjacent component that solve prior art existence.
The utility model comprises two groups of planetary gears, two groups of planetary gears are arranged in a sun wheel shaft, the sun gear of two groups of planetary gears is fixedly connected with sun wheel shaft, the gear ring of two groups of planetary gears is fixedly connected with by crossbeam, planetary gear carrier corresponding fixed block or the movable part each other of two groups of planetary gears, solve technological scheme that its technical problem adopts be the upper and lower two ends of planetary gear carrier of two groups of planetary gears respectively and a retaining spring is set between crossbeam, retaining spring one end is fixed on the fixed base of crossbeam, the retaining spring the other end is fixed on corresponding planetary gear carrier.
Working principle of the present utility model: when the planetary gear carrier of first group of planetary gears is as fixed block, the planetary gear carrier of second group of planetary gears is as driven member, when two groups of sun gears rotate as driving link postive direction, because the planetary gear carrier of first group of planetary gears maintains static, the planetary gear carrier of second group of planetary gears just achieves the speed change of the planetary gear carrier of driving link sun wheel shaft and driven member second group of planetary gears along with second group of planetary revolution of planetary gears, during speed change, the retaining spring setting up and down by the planetary gear carrier of second group of planetary gears carries out location of fluctuating, planetary gear carrier and adjacent planetary pinion or sun gear generation wiping is avoided to touch, when the planetary gear carrier of second group of planetary gears is as fixed block, the planetary gear carrier of first group of planetary gears is as driven member, and working principle is also identical.
The utility model passes through at the planetary gear carrier of two groups of planetary gears floating retaining spring setting up and down, avoid planetary gear carrier and adjacent planetary pinion or sun gear generation wiping to touch, there is the advantage of simple, the stable and long service life of structure.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1 sun wheel shaft, 2 sun gears, 3 sun gears, 4 gear rings, 5 gear rings, 6 crossbeams, 7 planetary gear carriers, 8 planetary gear carriers, 9 retaining springs, 10 fixed bases in figure.
Embodiment
As shown in the figure, a kind of dual planetary gear speed reducer floating positioning device, comprise two groups of planetary gears, two groups of planetary gears are arranged in a sun wheel shaft 1, the sun gear 2 of two groups of planetary gears is fixedly connected with sun wheel shaft 1 with sun gear 3, the gear ring 4 of two groups of planetary gears is fixedly connected with by crossbeam 6 with gear ring 5, the planetary gear carrier 7 of two groups of planetary gears and planetary gear carrier 8 be corresponding fixed block or movable part each other, planetary gear carrier 7 and planetary gear carrier about 8 two ends are respectively and arrange a retaining spring 9 between crossbeam 6, retaining spring 9 one end is fixed on the fixed base 10 of crossbeam, retaining spring 9 the other end is fixed on corresponding planetary gear carrier.
Working principle of the present utility model: when the planetary gear carrier of first group of planetary gears is as fixed block, the planetary gear carrier of second group of planetary gears is as driven member, when two groups of sun gears rotate as driving link postive direction, because the planetary gear carrier of first group of planetary gears maintains static, the planetary gear carrier of second group of planetary gears just achieves the speed change of the planetary gear carrier of driving link sun wheel shaft and driven member second group of planetary gears along with second group of planetary revolution of planetary gears, during speed change, the retaining spring setting up and down by the planetary gear carrier of second group of planetary gears carries out location of fluctuating, planetary gear carrier and adjacent planetary pinion or sun gear generation wiping is avoided to touch, when the planetary gear carrier of second group of planetary gears is as fixed block, the planetary gear carrier of first group of planetary gears is as driven member, and working principle is also identical.
