Abstract
The invention discloses a gear box, wherein the gear box comprises a central gear shaft, three gears, a gear shell and metal sheets of two fixed gears, wherein the three gears are meshed with the central gear shaft externally; the gear shell is meshed with the three gears internally; and the outer diameter of each metal sheet is greater than the inner diameter of the gear shell. In the gear shell, through the mutual rotation of a plurality of fixed gears, the transmission ratio among the gears is much greater, and the transmission efficiency of the gears is increased, thus the using efficiency of the gears in the using process is increased.
Description
Technical field
The present invention relates to a kind of automobile component, be specifically related to a kind of gear-box.
Background technique
Gear-box is widely used at mechanical engineering field, such as all receiving extensive utilization at driving parts of wind power generating set, vehicle transmission part, ship etc.
Present domestic gear-box receives the limitation of structural type, and the transmission of power ability is not high, uses gear-box like the T300 type ship, and its structural type is a double reduction.For making reversing output opposite with the axle steer of ahead running output; It adopts the drive mechanism of gap bridge idle gear; This structural type is bigger to the influence that the engagement and the force status of idle gear produced; Make it the force status variation, also limited the transmission capacity of gear simultaneously, therefore satisfied not the demand in market.
Summary of the invention
The object of the present invention is to provide the high gear-box of a kind of transmission efficiency.
Technological scheme of the present invention is; A kind of gear-box, described gear-box comprise a sun gear shaft, with three gears of sun gear shaft outer gearing; With the tinsel of meshed gears shell and two fixed gears in three gears, the external diameter of described tinsel is greater than the internal diameter of gear hub.
In preferred embodiment of the present invention; Described second tinsel is provided with one and is orthohexagonal anchor post by what six Steel Supports were processed; Wherein, Be through hole that three Steel Supports of equilateral triangle pass three gears respectively and fix the position of gear, other three Steel Supports are connected fixing with first tinsel.
In preferred embodiment of the present invention, described second metal is provided with groove near gear one side, is placed with a metal backup in the groove, and metal backup and gear are fixed through the different metallic support.
In preferred embodiment of the present invention; The central position of described two tinsels all offers through hole; Said sun gear shaft passes the through hole of first tinsel; The inboard of this through hole is a smooth surface, and the second tinsel through hole inboard is provided with wheel tooth, and wheel tooth is consistent with the wheel tooth direction of gear hub.
According to the invention is a kind of gear-box, adopts the rotation of a plurality of fixing gears through each other to make the velocity ratio between the gear higher in that gear hub is inner, and the transmission efficiency of the gear that makes increases, thereby has increased gear utilization efficiency in use.

Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
According to the invention is a kind of gear-box; Referring to Fig. 1; Described gear-box 1 comprises a sun gear shaft 2, with three gears 3 of sun gear shaft 2 outer gearings, with meshed gears shell 4 in three gears 3; And the external diameter of first tinsel 5 of fixed gear both sides and 6, two tinsels of second tinsel is all greater than the internal diameter of gear hub.Be provided with groove at second tinsel 6 near gear one side, be placed with a metal backup 7 in the groove.Second tinsel 6 is provided with one and is orthohexagonal anchor post by what six roots of sensation Steel Support 8 was processed; Wherein, Be through hole that three Steel Supports 8 of equilateral triangle pass three gears 3 respectively and fix the position of gear 3; Metal backup 7 is fixing through different metallic support 8 with gear 3, and other three Steel Supports 8 pass metal backup 7 and are fixedly connected with first tinsel 6.Central position at two tinsels all offers through hole, and wherein sun gear shaft 2 passes the through hole of first tinsel 5, and the inboard of this through hole is a smooth surface, and second tinsel, 6 through hole inboards are provided with wheel tooth, and wheel tooth is consistent with the wheel tooth direction of gear hub.
According to the invention is a kind of gear-box, adopts the rotation of a plurality of fixing gears through each other to make the velocity ratio between the gear higher in that gear hub is inner, and the transmission efficiency of the gear that makes increases, thereby has increased gear utilization efficiency in use.
The above is merely embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any those of ordinary skill in the art are in the technical scope that the present invention disclosed; Variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
