Abstract
The utility model provides a gearbox. The gearbox comprises a box body, and four gears, namely a first gear, a second gear, a third gear and a fourth gear are arranged in the box body, wherein the center of the first gear is located at one apex of an isosceles triangle, the center of the second gear is located at one apex of the isosceles triangle, the center of the third gear is located at the other apex of the isosceles triangle, and the center of the fourth gear is located on the perpendicular bisector of the bottom edge of the isosceles triangle. According to the gearbox, the gears in the gearbox are arranged reasonably, the utilization rate of space is increased, the size of the external box body is reduced, and therefore the size of the gearbox is reduced.
Description
Technical field
The utility model relates to a kind of gear-box, relates in particular to a kind of one-level gear-box.
Background technique
The application of gear-box in motor is very extensive, and is an important mechanical part, and its major function has: 1, acceleration-deceleration is exactly the speed-change gear box of often saying.2. change transmission direction, for example we can be with the power vertical transmission to another rotatingshaft with two tooth sector.3. change moment of rotation.Under the Same Efficieney condition, the faster gear that speed turns, the suffered moment of axle is less, otherwise larger.4, clutch function: we can by separating two originally meshed gears, reach the purpose that motor and load are separated.Such as brake clutch etc.5, distributed power.For example we can be with a motor, drive by the gear-box main shaft a plurality of from axle, thereby realize the function of a plurality of loads of driven by engine.
But existing gear-box usually will relate to achieve these goals a plurality of gears are installed, that so just gear-box need to be done is very large, thereby has improved manufacture cost, cost of transportation, and install also very inconvenient.
In view of this, be necessary existing gear-box is improved, to address the above problem.
The model utility content
The purpose of this utility model is to provide a kind of gear-box, and it has overcome prior art middle gear case middle gear and has arranged unreasonablely, causes the excessive problem of gear-box.
For realizing above-mentioned model utility purpose, a kind of gear-box of the present utility model, it comprises casing, described box house is provided with four gears, be respectively the first gear, the second gear, the 3rd gear, the 4th gear, wherein the center of first, second and third gear lays respectively at three summits of an isoceles triangle shape, on the perpendicular bisector on the base that is centered close to described isosceles triangle of the 4th gear.
As further improvement of the utility model, the outside that is centered close to described isosceles triangle of described the 4th gear, and the position on the base of close described isosceles triangle.
As further improvement of the utility model, the centre distance of described the 4th gear the perpendicular distance of place, center straight line of second and third gear be 25mm.
As further improvement of the utility model, described second and third, the diameter of four gears is greater than the diameter of described the first gear.
As further improvement of the utility model, described second and third, the size of the diameter of four gears is 150mm.
As further improvement of the utility model, the size of the diameter of described the first gear is 130mm.
As further improvement of the utility model, all sides of described first, second, third and fourth gear also offer some mounting holes.
As further improvement of the utility model, the quantity of all side mounting holes of described each gear is four.
As further improvement of the utility model, the thickness of the sidewall of described casing is greater than the thickness of described casing roof.
As further improvement of the utility model, the bottom of the casing of described gear-box also is provided with for the base that supports.
Compared with prior art, the beneficial effects of the utility model are: the gear in the gear-box of the present utility model is arranged rationally, has increased the utilization ratio in space, thereby has reduced the volume of external box of microvave, and then has reduced the volume of gear-box.
Description of drawings
Fig. 1 is the schematic representation of gear-box of the present utility model, and it has showed the mode that inner gear of the gear box is arranged.
Embodiment
Below in conjunction with each mode of execution shown in the drawings the utility model is elaborated; but should be noted that; these mode of executions are not limitation of the utility model; those of ordinary skills all belong within the protection domain of the present utility model according to these mode of execution institute work energy, method or structural equivalent transformation or alternative.
As shown in Figure 1, be the schematic representation of present embodiment middle gear case 100, it comprises casing 10, reaches four gears 11 of casing 10 inside.Four gears are respectively the first gear 111, the second gear 112, the 3rd gear 112, the 4th gear 114, first, second and third gear 111,112,113 center three summits laying respectively at an isoceles triangle shape wherein are on the perpendicular bisector on the base that is centered close to above-mentioned isosceles triangle of the 4th gear 114.
Further, the outside that is centered close to isosceles triangle of the 4th gear 114, and the position on the base of close isosceles triangle.Preferably, this isoceles triangle shape is the obtuse angle isosceles triangle.
Wherein, second and third, four gears 112,113,114 diameter are greater than the diameter of described the first gear 111.In the present embodiment, second and third, the size of four gears 112,113,114 diameter is 150mm; The size of the diameter of the first gear 111 is 130mm.
Gear 11 can make each gear be in rational position according to above-mentioned arrangement mode, has increased the utilization ratio in space, thereby has reduced the volume of external box of microvave 10, and then has reduced the volume of gear-box 100.The preferred length of present embodiment middle gear case 100 is 700mm.
Simultaneously, for the needs that assemble, also offer some mounting holes 12 in all sides of each gear 11, and the mounting hole 12 of each gear 11 all side distributes evenly.Preferably, the quantity of each gear 11 all side mounting hole 12 is four, totally 12 mounting holes 12.Four mounting holes 12 in every group consist of a square.
