Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural drawing of the present invention.
Embodiment
As shown in Figure 1, speed-change gear box of the present invention, has gear-box 100 and Worm gear case 200; The end of the input shaft 11 of gear-box 100 is positioned at gear-box 100, and this end is provided with initiatively bevel gear 12, and the passive shaft of bevel gear 20 of the passive bevel gear 13 engaged with this active bevel gear 12 is connected and drives one five to keep off speed change gear structure.
Described five gear speed change gear structures comprise five driving gears coaxial with passive bevel gear 13 to 21, 22, 23, 24, 25, each driving gear is to comprising the large driving gear and a small active gear that are mutually connected, a driving gear near passive bevel gear 13 is installed on passive shaft of bevel gear 20 to 21 with spline, other four driving gears are to 22, 23, 24, 25 are set on passive shaft of bevel gear 20 with bearing rotationally, also namely passive bevel gear 13 can drive driving gear to 21 by passive shaft of bevel gear 20, and four driving gears are to 22, 23, 24, 25 are not driven by passive shaft of bevel gear 20.
Five gear speed change gear structures also comprise four coaxial driven gears to 31,32,33,34, each driven gear is to comprising the large driven gear and a little driven gear that are mutually connected, four driven gears to being set on same rooted tooth wheel shaft 30 rotationally with bearing respectively, also namely gear shaft 30 only play support driven gear to 31,32,33,34 effect.
Each driven gear is to corresponding to two adjacent driving gears pair, the right large driven gear of each driven gear small active gear right with driving gear engages, and the right little driven gear of each driven gear large driving gear right with another driving gear engages.Also namely: driven gear corresponds to two adjacent driving gears to 21,22 to 31, driven gear to 31 large driven gear and driving gear to 21 small active gear engage, driven gear to 31 little driven gear and driving gear to 22 large driven gear engage; Driven gear corresponds to two adjacent driving gears to 22,23 to 32, driven gear to 32 large driven gear and driving gear to 22 small active gear engage, driven gear to 32 little driven gear and driving gear to 23 large driven gear engage; Driven gear corresponds to two adjacent driving gears to 23,24 to 33, driven gear to 33 large driven gear and driving gear to 23 small active gear engage, driven gear to 33 little driven gear and driving gear to 24 large driven gear engage; Driven gear corresponds to two adjacent driving gears to 24,25 to 34, driven gear to 34 large driven gear and driving gear to 24 small active gear engage, driven gear to 34 little driven gear and driving gear to 25 large driven gear engage.
Material is thus formed chain: passive bevel gear 13-passive shaft of bevel gear 20-driving gear to 21 large driving gear-driving gear to 21 small active gear-driven gear to 31 large driven gear-driven gear to 31 little driven gear-driving gear to 22 large driving gear-driving gear to 22 small active gear-driven gear to 32 large driven gear-driven gear to 32 little driven gear-driving gear to 23 large driving gear-driving gear to 23 small active gear-driven gear to 33 large driven gear-driven gear to 33 little driven gear-driving gear to 24 large driving gear-driving gear to 24 small active gear-driven gear to 34 large driven gear-driven gear to 34 little driven gear-driving gear to 25 large driving gear.
Due to this Transmitted chains, five driving gears form five kinds of rotating speeds to five large driving gears of 21,22,23,24,25.
Five gear speed change gear structures also comprise a moveable output gear 41, this output gear 41 is slidably mounted on an output shaft 42 with spline fitted, after output gear 41 moves can respectively with five driving gears to 21,22,23,24,25 large driving gear engage.Thus output gear 41 can five gear speed changes.
