Description
Technical field
The utility model relates to retarder, particularly relates to planetary reducer.
Background technique
Traditional planetary reducer conventional structure generally comprises reduction case and is located at least two-stage planet reducing gear of reduction case inside, wherein, the sun gear of first order planetary gear reducing mechanism connects with motor output shaft, and the sun gear of afterbody planetary gear reducing mechanism connects with output shaft.Because the specification of planetary gear reducing mechanism at different levels is different, therefore manufacturing can be very complicated, the more important thing is, once certain damage parts, many times a whole set of planetary gear reducing mechanism all needs to change, and to meet higher cooperation requirement, therefore manufacture and maintenance cost can be very high.
Model utility content
Technical problem to be solved in the utility model is just to provide a kind of segmented planetary reducer, reduces processing and maintenance cost.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: a kind of segmented planetary reducer, comprise reduction case and be located at least two-stage planet reducing gear of reduction case inside, wherein, the sun gear of first order planetary gear reducing mechanism connects with motor output shaft, the sun gear of afterbody planetary gear reducing mechanism connects with output shaft, described reduction case comprises input end flange and output terminal flange, described at least two-stage planet reducing gear is arranged side by side between described input end flange and output terminal flange, the ring gear external diameter of planetary gear reducing mechanism at different levels and thickness are all identical, ring gear at different levels and input end flange and output terminal flange side by side folded merga pass fixing bolt are fixed, at least three fixing bolts are circumferentially with along reduction case, described fixing bolt is successively through output terminal flange, ring gear at different levels and input end flange, described output shaft is installed on output terminal flange, described output terminal flange is provided with the bearing supporting output shaft, seal ring is provided with between described output terminal flange and output shaft.
Preferably, described ring gear one side end face is along being equipped with outward flange outward, and described ring gear opposite side end face is provided with inner convex platform at middle part, and the outward flange between adjacent ring gear is around being arranged on outside inner convex platform.
Preferably, the corresponding described inner convex platform of described input end flange and output terminal flange or outward flange are provided with the outward flange or inner convex platform that coordinate with it.
Preferably, between described ring gear and ring gear and ring gear and input end flange, be provided with packing ring between output terminal flange.
Preferably, described seal ring section is in " people " font.
The utility model has unified the ring gear of planetary gear reducing mechanism at different levels, so can reduce the specification of ring gear, reduces the production management cost of part.In addition, during gear failure wherein, can change accordingly it, unnecessary whole gear ring is changed, and saves maintenance cost.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Fig. 1 is the segmented planetary reducer structural representation being provided with secondary planetary gear reducing mechanism;
Fig. 2 is the segmented planetary reducer structural representation being provided with three-stage planetary gear reducing gear.
Embodiment
As depicted in figs. 1 and 2, a kind of segmented planetary reducer, comprise reduction case 1 and be located at least two-stage planet reducing gear 2 of reduction case inside, wherein, the sun gear of first order planetary gear reducing mechanism connects with motor output shaft, the sun gear of afterbody planetary gear reducing mechanism connects with output shaft 3, described reduction case 1 comprises input end flange 11 and output terminal flange 12, described at least two-stage planet reducing gear is arranged side by side between described input end flange and output terminal flange, ring gear 21 external diameter of planetary gear reducing mechanism at different levels and thickness are all identical, ring gear at different levels and input end flange and output terminal flange side by side folded merga pass fixing bolt 15 are fixed, at least three fixing bolts are circumferentially with along reduction case, described fixing bolt is successively through output terminal flange, ring gear at different levels and input end flange, described output shaft is installed on output terminal flange, described output terminal flange is provided with the bearing 13 supporting output shaft, seal ring 14 is provided with between described output terminal flange and output shaft.
Described ring gear one side end face is along being equipped with outward flange 22 outward, and described ring gear opposite side end face is provided with inner convex platform 23 at middle part, and the outward flange between adjacent ring gear is around being arranged on outside inner convex platform.The corresponding described inner convex platform of described input end flange and output terminal flange or outward flange are provided with the outward flange or inner convex platform that coordinate with it.Between described ring gear and ring gear and ring gear and input end flange, be provided with packing ring between output terminal flange.The benefit done like this is convenient between ring gear and the closely cooperating of ring gear and input end flange and output terminal flange.In addition, described seal ring section, in " people " font, forms good sealing.
It has unified the ring gear of planetary gear reducing mechanism at different levels, so can reduce the specification of ring gear, reduces the production management cost of part.In addition, during gear failure wherein, can change accordingly it, unnecessary whole gear ring is changed, and saves maintenance cost.
Wherein, Fig. 1 is the segmented planetary reducer being provided with secondary planetary gear reducing mechanism, Fig. 2 is the segmented planetary reducer being provided with three-stage planetary gear reducing gear, even but more multistage planetary gear reducing mechanism is set in retarder, because the specification of each gear ring is consistent, the manufacture cost and the maintenance cost that increase primary planet pinion reducing gear are all very low.
