Abstract
The utility model discloses a novel oil seal structure for a transmission input shaft. The novel oil seal structure comprises an input shaft end cover, an oil seal, a transmission front shell, an oil return passage and an oil return hole, wherein the oil return passage is arranged on the input shaft end cover, and the oil return hole is formed in the transmission front shell. The oil return passage is communicated with the oil return hole. Compared with the prior art, oil pressure at the oil seal position is decreased, and possibility of oil leakage is reduced due to the arrangement of the oil return passage at the input shaft oil seal position.
Description
Technical field
The utility model relates to a kind of oil seal structure for the transmission input shaft place.
Background technique
Transmission input shaft rear end cover oil impregnate phenomenon is general in the prior art, the solution that there is no at present.
Summary of the invention
Technical problem to be solved in the utility model is for the deficiencies in the prior art, and a kind of transmission input shaft oil seal structure that prevents the speed changer oil impregnate is provided.
For solving this technical problem, the utility model provides a kind of novel transmission input shaft oil seal structure, comprise input shaft end cap, oil sealing and speed changer fore shell, also comprise being arranged on back oil road that input shaft end covers and the spill port of speed changer fore shell, described back oil road and spill port UNICOM.
Beneficial effect: the utility model compared with prior art owing at the input shaft oil seal place back oil road is set, can reduce oil sealing place oil pressure, reduces the possibility of oil impregnate.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1 input shaft end cap, 2 input shaft oil seals, 3 speed changer fore shells, 4 back oil roads, 5 spill ports, 6 bearings.
Embodiment
Below in conjunction with drawings and Examples the utility model is done specific descriptions.
Figure 1 shows that structural representation of the present utility model.
The utility model comprises input shaft end cap 1, oil sealing 2 and speed changer fore shell 3, also comprises the back oil road 4 that is arranged on the input shaft end cap 1 and the spill port 5 of speed changer fore shell 3, described back oil road 4 and spill port 5 UNICOMs.
The utility model is realized by following technical measures:
In gear oil enters input shaft end cap 1 cavity, gear oil is pooled to input shaft end cap 1 bottom, make bearing 6, oil sealing 2 obtain sufficient lubrication, when gear oil is pooled to certain height, can get back to speed changer inside by the spill port 5 on the speed changer fore shell 3 by the back oil road 4 that input shaft end cap 1 leaves, make the inner oil seal place can not form oil pressure, can satisfy the possibility that reduces oil impregnate when inner oil seal lubricates.
The utility model compared with prior art owing at the input shaft oil seal place back oil road is set, can reduce oil sealing place oil pressure, reduces the possibility of oil impregnate.
The utility model can pass through or adopt existing techniques in realizing without the technical characteristics of describing; above-mentioned explanation is not to be to restriction of the present utility model; also be not limited only to above-mentioned giving an example; the variation that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement also should belong to protection domain of the present utility model.
