Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
See Fig. 1 and Fig. 3, a kind of speed changer two axle assembly, comprise two axles 1, four gear gears 3 are arranged with from left to right successively outside two axles 1, three gear gears 4, second gear 5, first gear 6 and reverse gear 7, the left side of four gear gears 3, three keep off between gears 4 and second gear 5 and are equipped with sliding sleeve 2 between first gear 6 and reverse gear 7, the external splines of sliding sleeve 2 is teeth structure, the internal spline of the gear adjacent with sliding sleeve 2 is also teeth structure, and the internal spline of the external splines of sliding sleeve 2 and the gear adjacent with sliding sleeve 2 is meshed, four gear gears 3, three gear gears 4, second gear 5, four gear gear spacers 9 are arranged with respectively in first gear 6 and reverse gear 7, three gear gear spacers 11, second gear spacer 12, first gear spacer 13 and reverse gear spacer 15, the left side of four gear gear spacers 9 is provided with stop ring 8, stop ring 8 is set on two axles 1,
Wherein, three gear gears 4, second gear 5, first gear 6 and two shaft diameters corresponding to reverse gear 7 are greater than two shaft diameters corresponding to four gear gears 3, and three gear gears 4, second gear 5, first gear 6 and two axles 1 corresponding to reverse gear 7 are arranged with two two axle hex keys 14, the left end of two two axle hex keys 14 is respectively equipped with a straight pin 10, the lower end of two straight pins 10 is inserted on two axles 1, the inner side of three gear gear spacers 11 is arranged with two grooves, the upper end of two straight pins 10 is inserted in two grooves inside three gear gear spacers 11 respectively.
