Abstract
The utility model relates to a gear box the speed changing gear wheel of which can be fully lubricated. The gear box comprises a gear box body and a plurality of speed changing gear wheels. The gear box body comprises an oil storing tank used for containing the machine oil. The speed changing gear wheel is arranged inside the gear box body, the position of the speed changing gear wheel is lower than that of the oil storing tank. The machine oil falls onto the speed changing gear wheel when the machine oil overflows out from the oil storing tank. The utility model has the advantages of that the machine oil flows out from a through hole under the pressure of the machine oil pump, originally enters into the oil storing tank, and then enables the amount of the overflowed machine oil to become more even and steady through the adjusting function of the oil storing tank. The utility model can fully lubricate the speed changing gear wheel, and dispose the problem that the lubrication is inadequate due to the spraying direction and range limit to the customized technologies.
Description
Technical field
The utility model relates to a kind of gearbox, but particularly relevant for a kind of gearbox of sufficient lubrication speed change gear.
Background technique
In the engine gearbox, be provided with speed change gear, in order to changing the torque magnitude of engine output, to be fit to various running condition (climbing etc.) fast, at a slow speed.The present lubricating system of speed change gear, utilize the fuel feeding path with spray regime to speed change gear fuel feeding person, yet this kind lubricating system is subject to injection direction and spray regime, makes that speed change gear can't sufficient lubrication on the transmission shaft.
The model utility content
But the purpose of this utility model is to provide a kind of gearbox of sufficient lubrication speed change gear.
But the purpose of this utility model is achieved in that the gearbox of sufficient lubrication speed change gear and comprises a gearbox casing and a plurality of speed change gear.Gearbox casing comprises an oil storage tank, is used to hold machine oil.Speed change gear is arranged in the gearbox casing, and the position of speed change gear is low than oil storage tank, and when machine oil was gone out by the oil storage tank overflow, machine oil dropped down onto on the speed change gear.
Oil storage tank speed change gear axially on extend and have a set length dimension, make overflow and under machine oil along the axial distribution of speed change gear, thereby can sufficient lubrication to speed change gear, therefore can solve known techniques and be subject to injection direction and spray regime and produce lubricated inadequate problem.
The utility model has the advantages that: machine oil is sprayed by through hole under the pressure of oil pump, be introduced into oil storage tank, regulatory function by oil storage tank, make that the oil level of overflow is more even and stable, the utility model can sufficient lubrication to speed change gear, solved known techniques and be subject to injection direction and spray regime and produce lubricated inadequate problem.

Embodiment
Please consult Figure 1A and Figure 1B simultaneously, Figure 1A is the three-dimensional exploded view according to engine cylinder body of the present utility model and gearbox casing, and Figure 1B is a three-dimensional exploded view of observing engine cylinder body and gearbox casing from other direction.Gearbox casing 20 comprises right lid 21, one right shell body 22, a left shell 23 and a left side lid (not icon).Cylinder block 10 is installed in a side of gearbox casing 20, and is connected with right shell body 22 and left shell 23 formed cavitys, and speed change gear ( label 27,28 those shown among Fig. 2) is arranged in this cavity.
Shown in Figure 1B, the left surface of right side lid 21 is provided with one first groove 211 and one first hole 212, and first groove 211 and first hole 212 are connected.
Shown in Figure 1A, the right flank of right shell body 22 is provided with one second groove 221, one second hole 222, a first flow 223 and a through hole 224, and wherein second hole 222, first flow 223 and through hole 224 are connected.Must notice that through hole 224 extends to left surface by the right flank of right shell body 22, and be connected with oil storage tank 225 on being arranged on left surface.One extension part 226 also is set on the left surface of right shell body 22 in addition, and the position of extension part 226 is low than oil storage tank 225.
When operation, oil pump (not icon) is delivered to second runner 211,221 with machine oil, enters first flow 223 via first hole 212, second hole 222 then, flows in the oil storage tank 225 via through hole 224 again.Behind the full machine oil of oil storage tank 225 storages, shown in the 2nd figure, machine oil will overflow oil storage tank 225, then along the guiding of extension part 226, flow to the speed change gear 27,28 of below, and will be lubricated.
In the present embodiment, extension part 226 is an en plaque, the length of extension part 226 on axially (the perhaps direction of vertical paper) of speed change gear 27,28 is identical with oil storage tank 225, be used to accept the machine oil of overflow, and guiding machine oil flow to speed change gear 27,28 downwards.
