Embodiment Construction

[0014] As shown in Fig. 5, Fig. 6 and Fig. 7: the present invention consists of a main shaft 1, a secondary shaft 2, a first gear driving gear 3, a first gear driven gear 4, a gear 5, a spline gear 6, a shift slider 7, a gear The first-stage double gear 8, the bridge gear 9, the first-stage double gear shaft 10, the bridge gear shaft 11, the washer 12, the first-stage double gear bushing 13 and the bridge gear bushing 14, etc. There is a Gear driving gear 3, a gear driven gear 4 and a gear 5 are arranged on the secondary shaft 2, and a spline gear 6 is installed between the gear 5 and the first gear driven gear 4, and its structural features are: A, on the main shaft 1 and The position corresponding to the gear 5 is provided with a shift slider 7, and the shift slider 7 is set on the main shaft 1 through a spline and a spline groove; Gear 9, one gear of the first-stage duplex gear 8 meshes with the first gear driven gear 4, the other gear meshes with the bridge gear 9, and the...

Abstract

In one kind of engine sets at the reverse gear organization, mainly by the main axle 1, countershaft 21 shopkeepers moves the gear 31 grades of driven gears 4, the gear 5, spline the gear 6, changes the files slide 7, level of doubles bond gears 8 levels of idle wheels 9 and so on the constitution, the main axle on 1 has a shopkeeper to move gear 3, countershaft on 2 has grade of driven gears 4 and the gear 5, between 4 installs on the gear with grade of driven gears has spline the gear 6, its structure characteristic lies in: On 1 has in the main axle with the gear 5 correspondences position establishments changes the files slide 7, the change files slide 7 passes spline and the flowered key slot coverall in the main axle on 1; Has level of double joint gears in countershaft a 2 side establishment 8 and the idle wheel 9, a level of double joint gears 8 gear 4 meshes to grade of driven gears, another gear and the idle wheel 9 mesh, the idle wheel at the same time 9 5 meshes with the gear. This invention intensity good, various grade of velocity ratios more reasonable, cost low, the installment is convenient.

Description

technical field [0001] The invention relates to a reverse gear mechanism, in particular to an engine built-in reverse gear mechanism. Background technique [0002] The traditional engine reverse gear mechanism has two structural types: external and internal. External means that the reverse gear mechanism is arranged outside the engine. There is no reverse gear on the main shaft 1 and auxiliary shaft 2 in the engine. The main shaft 1 and auxiliary shaft 2 A rotatable (fourth gear driven) gear 5 (as shown in Figure 1) is arranged on the top, and the installation and use of the reverse gear mechanism are inconvenient, and the cost is relatively high. In order to realize the built-in reverse gear mechanism, someone changes the second gear of the engine into a reverse gear through a bridge gear 15, and the reverse gear driving gear 16, the reverse gear driven gear 17 and the bridge gear 15 are on the same plane (as shown in the figure 3), due to the str...
