Specific embodiment
With reference to the accompanying drawing, specific embodiment of the utility model is described in further detail:
The utility model is that Bevel Gear Transmission is combined by common planetary gear speed change gear, and composition unidirectionally inputs two-way defeated
Two gear speed change gears out.Specific structure is as shown in Figure 1, Figure 2 and Figure 3, planetary speed variator, including three planet teeth
Wheel 4, three planetary gears 4 are centered around around sun gear 6, and with 6 external toothing of sun gear；Three planetary gears 4 are also located at internal tooth
Circle 12 in, and with 12 internal messing of ring gear.
As shown in Figure 5 and Figure 6, each planetary gear 4 is mounted in planetary gear shaft 2 by a pair of of planetary gear bearing 3 respectively
On；Three 2 upper and lower ends of planetary gear shaft are separately fixed at uplink carrier 1, in downlink carrier 5；
Sun gear 6 is fixedly mounted in sun wheel shaft 16；16 upper and lower ends of sun wheel shaft of sun gear 6 pass through respectively it is upper too
Positive wheel bearing 7, lower sun gear bearing 8 are mounted on uplink carrier 1, in downlink carrier 5；
Bevel pinion 9 is fixedly mounted on 16 upper half of sun wheel shaft, and is located at 1 outside of uplink carrier, with circlip 17
Axial restraint is fitted into the wheel hub of 16 upper end of sun wheel shaft on top gear output shaft 10 by flat key with keyway 18.
As shown in figure 4, the upper end outer wall of ring gear 12 is fixed with bevel gear wheel 11 with one heart；12 lower end of ring gear and connecting pin
Lid 13 is fixedly connected by flange, and the center of connection end cap 13 is fixedly connected with high torque by flat key and keeps off output shaft 14.
Assembling process is that planetary gear 4 passes through a pair of of planetary gear bearing 3 in planetary gear shaft 2, to guarantee planet
Planetary gear 4 is freely rotated when 6 engaged transmission of gear 4 and sun gear.And sun gear 6 and sun wheel shaft 16 constitute monoblock type tooth
Wheel；Uplink carrier 1 by interference fit connection three planetary gear shafts 2, between uplink carrier 1 and sun wheel shaft 16 by it is upper too
Positive wheel bearing 7 connects, and sun gear bearing 7 and sun wheel shaft 16 are assembled by clearance fit, installation sun gear 6 and planetary gear 4
Engagement；Next the lower sun gear bearing 8 of installation another side, installs downlink carrier 5, and assembly relation is identical as uplink carrier 1；Greatly
