In conjunction with a kind of reversing box shown in Fig. 1 to Fig. 5, including casing 7 and be located in described casing 7 Power shaft 3, output shaft 8 and idle shaft 9, described power shaft 3 and the described parallel cloth of output shaft 8 Put, described power shaft 3 is arranged with tumbler gear 51 and axle sleeve 4, described tumbler gear 51 and institute The inboard gear stating axle sleeve 4 is meshed, and described axle sleeve 4 is connected with shift fork 2, on described power shaft 3 It is arranged with input shaft gear 53 and the first travelling gear 52, described axle sleeve 4 and described input shaft gear 53 are meshed, and described input shaft gear 53 and described first travelling gear 52 are positioned at described tumbler gear The both sides of 51, described output shaft 8 is arranged with the second travelling gear 54 and output shaft gear 55, institute State the second travelling gear 54 to be meshed with described first travelling gear 52, sheathed in described idle shaft 9 There are idle shaft gear 56 and the 3rd travelling gear 57, described 3rd travelling gear 57 and described output shaft Gear 55 is meshed.

In the present embodiment, described input shaft gear 53 and described first travelling gear 52 and described input Axle 3 is all rotationally connected by rolling bearing 6.

In the present embodiment, described power shaft 3 both sides and described casing 7 inwall joint are all arranged with rolling Dynamic bearing 6.

In the present embodiment, described power shaft 3 stretches out the part of described casing 1 and is arranged with power shaft successively Oil sealing 10 and power shaft end cap 11, described power shaft end cap 11 passes through bolt with described casing 7 outer wall Fixing connection.

In the present embodiment, described axle sleeve 4 periphery is provided with groove, and described shift fork 2 is provided with and described axle The pulling block that groove on set 4 coincide.

In the present embodiment, described output shaft 8 both sides and described casing 7 inwall joint are all arranged with rolling Dynamic bearing 6.

In the present embodiment, described output shaft 8 stretches out the part of described casing 7 and is provided with output shaft end cap 12, described output shaft end cap 12 is arranged with rolling bearing 6.

In the present embodiment, described output shaft 8 is positioned at described second travelling gear 54 and described output Part between shaft gear 55 is arranged with sleeve pipe 14.

In the present embodiment, described idle shaft 9 both sides and described casing 7 inwall joint are all arranged with rolling Dynamic bearing 6.

In the present embodiment, described idle shaft 9 is stretched out the part of described casing 7 and is provided with idle shaft end cap 13, described idle shaft end cap 13 is bolted to connection with described casing 7 outer wall.

In the present embodiment, power shaft 3 is placed in the A mouth of casing 7, and power shaft 3 passes through the axis of rolling Hold 6 and casing 7 cooperate, and by input shaft oil seal 10 and power shaft end cap 11 by described defeated Entering axle 3 to position, be fixed on casing 7, power shaft 3 and tumbler gear 51 are to closely cooperate Getting up, the first travelling gear 52 and input shaft gear 53 are connected by rolling bearing 6 and power shaft 3 Pick up, the little gear on the right side of tumbler gear 51 and the first travelling gear 52, input shaft gear 53 Left side the number of teeth of little gear, diameter be all identical, the internal gear of axle sleeve 4 just can and commutating tooth Wheel 51 engagement is got up, and shift fork 2 just blocks axle sleeve 4.

In conjunction with Fig. 1,2,4, output shaft 8 is placed in the C mouth of casing 7, and output shaft 8 is by rolling Dynamic bearing 6 and casing 7 cooperate and with output shaft end cap 12, described output shaft 8 are fixed on case On body 7, the second travelling gear 54 and output shaft gear 55 are the teeth by itself with output shaft 8 Groove closely cooperates, and has individual sleeve pipe 14 to incite somebody to action between the second travelling gear 54 and output shaft gear 55 Second travelling gear 54 and output shaft gear 55 location get up, on the left of output shaft 8 on coordinate upper flange 15。
