Fig. 1 is the sectional front view of the utility model.
Embodiment
Elaborate below in conjunction with the embodiment of accompanying drawing to the utility model.
By shown in Figure 1; The utility model comprises casing, input shaft, output shaft and planet carrier; Input shaft 11 is contained in respectively on the two side of casing 10 with output shaft 12, and two side through bearing be contained in casing on, on casing be equipped with and output shaft 12 corresponding passive tooth wheel shafts 13 respectively by input shaft 11 bottoms for planet carrier the right and left; Driving gear 1 is housed in casing on the input shaft 11; The driven gear 2 that is meshed with driving gear 1 is housed on the passive tooth wheel shaft 13, on output shaft 12, the passive tooth wheel shaft 13 planet carrier 4 is housed, symmetry is equipped with first gear shaft 14a, the second gear shaft 14b parallel with passive tooth wheel shaft 13, output shaft 12 in planet carrier 4 both sides; The first gear 5a is housed on the first gear shaft 14a; The second gear 5b is housed on the second gear shaft 14b, the coaxial first engaging gear 7a that is equipped with on the 3rd gear 6, the first gear shaft 14a that are meshed with the first gear 5a, the second gear 5b with first gear 5a symmetry is housed on the passive tooth wheel shaft 13; The coaxial second engaging gear 7b symmetrical with the second gear 5b is housed on the second gear shaft 14b, the output gear 8 that is meshed with the first gear shaft 14a, the second gear shaft 14b is housed on the output shaft 12.
In order to guarantee using effect, described passive tooth wheel shaft 13 1 ends link to each other with casing, and the other end links to each other with planet carrier 4 bearings; One side of described planet carrier 4 links to each other with driven gear 2 through first connecting body 3 and is sleeved on the passive tooth wheel shaft 13, and the opposite side of planet carrier 4 is sleeved on the output shaft 12 through second connecting body 9, and output shaft 12 1 ends link to each other with planet carrier 4 bearings.
Described casing and planet carrier are round or square; Described input shaft 11, output shaft 12 are contained on the casing both sides through bearing respectively; The first gear shaft 14a, the second gear shaft 14b two ends are contained on the planet carrier bi-side through bearing respectively.
When the utility model uses; The braking, the speed reducer that replace former machinery; Driving gear 1 drives driven gear 2; Make planet carrier 4 rotations; Thereby the 3rd gear 6 that the symmetrical two identical first gear 5a, the second gear 5b of drive installs around on passive tooth wheel shaft 13 rotates and rotation, is rotated by the first gear 5a, the symmetrical identical first engaging gear 7a, the second engaging gear 7b of second gear 5b drive, drives output gear 8 decelerations simultaneously by the first engaging gear 7a, the second engaging gear 7b and exports; The power of falling back forces output gear 8 counterrotatings during shutdown, and the first engaging gear 7a, second engaging gear 7b counter-rotating drives the first coaxial gear 5a, the second gear 5b reverses, the first gear 5a of counter-rotating, the second gear 5b and the 3rd gear 6 brake self-locking that is hampered; Because symmetry two teeth of output gear 8 are to mesh simultaneously with the first identical engaging gear 7a, the second engaging gear 7b, output torque is big.In case of necessity, can increase by the first identical gear 5a, the second gear 5b and the first engaging gear 7a, the second engaging gear 7b on the planet carrier 4, constitute three pairs or four pairs of structures that mesh output gear 8 simultaneously, output torque is bigger, and the output speed ratio reaches more than the 1-5000.
The utility model is through practical probation, and effect is very good, and is energy-conservation more than 20%, practices thrift 60% of the former braking of original equipment, retarding device cost, and safe in utilization, is the innovation on deceleration, the braking equipment, and economic and social benefit is remarkable.
