Abstract

The utility model discloses a gearbox which comprises a box body. A shaft I, a shaft II, a shaft III, a shaft IV, a shaft V and a shaft VI, which are arranged in parallel, and are rotationally connected with the box body; a main transmission gear is mounted on a shaft I; a I-gear gear, a II-gear gear and a reverse-gear gear are mounted on the shaft II; a first double-linked sliding gear and a transmission gear are mounted on the shaft III; a reduction pinion and a second double-lined sliding gear are mounted on the shaft IV; a reduction bull wheel and two single-side clutch sliding gears capable of disengaging from the reduction bull wheel are mounted on the shaft V; a spring keeping the power joint of the single-side clutch sliding gears and the reduction bull wheel is sleeved on the shaft V; and the shaft VI comprises two half shafts, and a reduction gear is mounted on each half shaft. The gearbox has the advantages of simple structure, small volume and low manufacture cost.

Description

A kind of gearbox

Technical field

The utility model relates to a kind of gearbox.

Background technique

Existing miniature rural area machinery is as the garden management machine, and its gearbox has three grades of transmission outputs three gears are promptly arranged, and wherein two gears are forward gear, and another gear is for retreating shelves.Existing gearbox is made of seven axles that be arranged in parallel, causes the complex structure of gearbox, volume bigger, has increased fabricating cost accordingly.

The model utility content

The technical problems to be solved in the utility model is at above-mentioned defective, and a kind of simple in structure, volume is little and fabricating cost is low gearbox is provided.

For solving the problems of the technologies described above, the utility model provides a kind of gearbox of following structure, comprise casing, its structural feature is: be rotatably connected to the I axle that be arranged in parallel on the described casing, the II axle, the III axle, the IV axle, V axle and VI axle, the main gear that passes is housed on the I axle, I shelves gear is housed on the II axle, II shelves gear and retreat a grade gear, first double crosslinking sliding gear and driving gear are housed on the III axle, the reduction pinion teeth and second double crosslinking sliding gear are housed on the IV axle, be equipped with on the V axle deceleration gearwheel and can be with two of deceleration gearwheel clutch monolateral clutch shifting slide gear, be with the spring that keeps monolateral clutch shifting slide gear to engage on the V axle with deceleration gearwheel power, the VI axle is made of two semiaxis, and a reduction gear respectively is housed on each root semiaxis.

The gearbox of said structure, compare with existing gearbox, though saved a transmission shaft and the gear that is contained on this transmission shaft, but still have and existing gearbox identical functions, promptly still can realize two forward gears and a power output that retreats shelves, when having saved a transmission shaft, reduced cost accordingly, also dwindled the volume of gearbox, therefore, advantage simple in structure, that volume is little and fabricating cost is low that gearbox provided by the utility model has.

Description of drawings

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:

Accompanying drawing is that the utility model makes structural representation.

Embodiment

Gearbox comprises casing 1 as shown in drawings, is rotatably connected to the I axle 2, II axle 3, III axle 4, IV axle 5, V axle 6 and the VI axle 7 that be arranged in parallel on the casing 1.I axle 2 is a power input shaft, is fixed with the main gear 8 that passes on it.Be fixed with I shelves gear 9, II shelves gear 10 on the II axle 3 and retreat grade gear 11.First double crosslinking sliding gear 12 is housed on the III axle 4 and is fixed with driving gear 13.Be fixed with reduction pinion teeth 14 on the IV axle 5 and second double crosslinking sliding gear 15 is housed.Be fixed with deceleration gearwheel 16 on the V axle 6 and 17, two monolateral clutch shifting slide gear 17 apportion deceleration gearwheels of two monolateral clutch shifting slide gears, 16 both sides are housed, two monolateral clutch shifting slide gears 17 can freely rotate and can be along 6 slips of V axle.The both ends of the surface of deceleration gearwheel 16 are provided with internal tooth, two monolateral clutch shifting slide gears 17 are duplicate gear, two monolateral clutch shifting slide gears 17 by separately one with deceleration gearwheel 16 end faces on internal tooth mesh or separate, realize the clutch of monolateral clutch shifting slide gear 17 and deceleration gearwheel 16.Also be with the spring 18 that keeps monolateral clutch shifting slide gear 17 to engage on the V axle 6 with deceleration gearwheel 16 power.VI axle 7 is a pto, is made of two semiaxis, respectively is fixed with a reduction gear 19 on each root semiaxis.The main gear 8 that passes meshes with I shelves gear 9, first double crosslinking sliding gear 12 can slide on III axle 4, first double crosslinking sliding gear 12 both can mesh with I shelves gear 9, can mesh with II shelves gear 10 again, can not mesh with I shelves gear 9 and II shelves gear 10 yet, second double crosslinking sliding gear 15 can slide on IV axle 5, second double crosslinking sliding gear 15 both can mesh with driving gear 13, also can with retreat grade gear 11 engagement,

reduction pinion teeth

14 and 16 engagements of deceleration gearwheel, another connection of a monolateral clutch shifting slide gear 17 meshes with being packed in a reduction gear 19 on the semiaxis, another connection of another monolateral clutch shifting slide gear 17 and reduction gear 19 engagements that are packed on another root semiaxis.

Two forward gearss of the utility model and a drive path following (Arabic numerals are the gear numbering in the accompanying drawing) that retreats shelves:

Advance: the I shelves: 8 → 9 → 12 13 → 15 14 → 16 17 → 19.

II shelves: 8 → 9 10 → 12 13 → 15 14 → 16 17 → 19.

Retreat: 8 → 9 11 → 15 14 → 16 17 → 19.

Gearbox provided by the utility model, decapacitation are used for also can be used on the small engineering machinery vehicles such as small sized loader, tractor, road roller and fork truck outside the machinery of miniature rural area.
