Description
Technical field
The utility model relates to a kind of gear-box of decorticator special use.
Background technique
Gear-box is to use very widely mechanical part in the motor, realizes acceleration-deceleration, changes transmission direction, changes the functions such as moment of rotation, clutch function, distributed power by meshed gears in the axle positioning hole on the casing and the case.The gear-box that existing decorticator is used has 6 pairs of axle positioning holes, and is distributed on the same level, and easy like this causing takies larger area when installing.
The model utility content
The purpose of this utility model provides a kind of structure and tightly beats, the gear-box that the little decorticator of occupation area is used.
The technological scheme that the above-mentioned purpose that realizes the utility model adopts is as follows:
A kind of gear-box, comprise the gear-box base, casing, the axle positioning hole, casing is fixed on the gear-box base, side at casing is provided with six axle positioning holes that the aperture is identical, wherein, first, second, the 3rd, the 4th axle positioning hole distributes in the same horizontal line successively, the 5th axle positioning hole be positioned at the 3rd and the 4th axle positioning hole the center directly over, the 6th axle positioning hole be positioned at the first axle positioning hole directly over, the 6th, first, second, the 3rd, the 5th, has successively identical spacing between the 4th axle positioning hole, the spacing of the 4th axle positioning hole and the 3rd axle positioning hole is the 3rd axle positioning hole and the second axle positioning hole spacing 1.5 times, is provided with six the axle positioning holes symmetrical with this side box body at relative opposite side casing.
Beneficial effect: the axle positioning hole distribution of the utility model gear-box is closed, structure is tightly beaten, floor space is little.
