Abstract

The utility model relates to the field of transmissions of automobiles, in particular to a lubricating mechanism for a bearing of an input end of a transmission. The lubricating mechanism comprises an input shaft, an oil seal, a shell, an input shaft bearing, an output shaft bearing and an output shaft. The output shaft is connected to an inner cavity of the input shaft through the output shaft bearing, and is coaxial with the input shaft. The lubricating mechanism is characterized in that an oil guiding plate is arranged on the inner side of the input shaft bearing; an oil stopping plate is arranged on the input shaft; an annular oil groove is formed in the inner side of the input shaft and corresponds to the input shaft bearing; an axial oil hole is formed in the output shaft; one end of the axial oil hole is communicated with the annular oil groove; and the other end of the axial oil hole is communicated with an inner cavity of the input shaft. Lubricating oil is fed from the outer side of the input shaft bearing, is distributed by the oil guiding plate, and respectively lubricates the input shaft bearing and the output shaft bearing; the oil stopping plate is arranged on the input shaft, so that the lubricating oil can slowly return to an oil line in the transmission; the service life of the bearing at the input end of the transmission is effectively prolonged; and the reliability of the transmission is improved.

Description

A kind of speed changer input end bearing-lubricating mechanism
Technical field
The utility model relates to automotive transmission class, specifically a kind of speed changer input end bearing-lubricating mechanism.
Background technique
Automotive transmission is the key components and parts in automobile, each axle of general speed changer is all connected with housing by bearing, the inner normal lubricating oil splash formula that adopts of speed changer is in the market lubricated, lubricant oil has been got rid of by the rotation of gear, or formation mist of oil, other gears and bearing in speed changer are lubricated, and bearing place is general all without auxiliary lubricating structure.The bearing of speed changer input end, particularly output shaft bearing, it is generally arranged in the inner chamber of input shaft, lubricant oil is difficult to enter it is lubricated, due in speed changer work often in the state of running up, as insufficient lubrication, the fault such as will cause bearing wear, burn to death, will cause scrapping of speed changer when serious.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and a kind of rational in infrastructure, the obvious speed changer input end of lubrication effect bearing-lubricating mechanism is provided.
The utility model is achieved through the following technical solutions:
A kind of speed changer input end bearing-lubricating mechanism, comprise input shaft, oil sealing, housing, bearing of input shaft, output shaft bearing, output shaft, output shaft is connected to by output shaft bearing in the inner chamber of input shaft, coaxially arranged with input shaft, it is characterized in that: bearing of input shaft inner side is provided with an oil guide plate, on input shaft, be provided with a grease baffle, on input shaft, be provided with an annular oil groove at corresponding bearing of input shaft inner side place, on output shaft, be provided with an axial oilhole, axially oilhole one end is communicated with annular oil groove, and the other end is communicated with input shaft inner chamber.
In the course of the work, lubricant oil has been got rid of by gear, enters from bearing of input shaft outside, passes through oil guide plate, parts of lubricating oil is led is fed back into axle bearing, another part lubricant oil is directed in the annular oil groove arranging on input shaft, by axial oilhole, flows into input shaft inner chamber, output shaft bearing is lubricated, on input shaft, be provided with a grease baffle, the step cylindrical of its inner lip and output shaft leaves less gap, and lubricant oil is slowly flowed back in the oil circuit of speed changer inside.
The utlity model has following beneficial effect: pass through oil guide plate, make lubricant oil shunting, bearing of input shaft and output shaft bearing are lubricated, are provided with grease baffle on input shaft, the step cylindrical of its inner lip and output shaft leaves less gap, make lubricant oil slowly flow back to the oil circuit of speed changer inside, output shaft bearing is effectively lubricated, and structure is ingenious, high lubricating effect, greatly improve the working life of bearing, improved the reliability of speed changer.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In Fig. 1: 1-input shaft, 2-oil sealing, 3-housing, 4-oil guide plate, 5-bearing of input shaft, 6-output shaft bearing, 7-grease baffle, 8-output shaft, the axial oilhole of 11-, 12-annular oil groove, 13, input shaft inner chamber
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, the utility model comprises input shaft 1, oil sealing 2, housing 3, bearing of input shaft 5, output shaft bearing 8, output shaft 8, output shaft 8 is connected to by output shaft bearing 6 in the inner chamber of input shaft 1, coaxially arranged with input shaft 1, it is characterized in that: bearing of input shaft 5 inner sides are provided with an oil guide plate 4, on input shaft 1, be provided with a grease baffle 7, on input shaft 1, be provided with an annular oil groove 11 in corresponding bearing of input shaft 5 outsides, on output shaft, be also provided with an axial oilhole 12, one end is communicated with annular oil groove 11, and the other end is communicated with input shaft inner chamber 13.
The utility model working procedure is as follows: in work, lubricant oil has been got rid of by gear, enter from bearing of input shaft 5 outsides, by oil guide plate 4, parts of lubricating oil is led is fed back into axle bearing 5, another part lubricant oil is directed in the annular oil groove 11 arranging on input shaft 1, by axial oilhole 12, flow into input shaft inner chamber 13, output shaft bearing 6 is lubricated, on input shaft 1, be provided with a grease baffle 7, the step cylindrical of its inner lip and output shaft 8 leaves less gap, lubricant oil is slowly flowed back in the oil circuit of speed changer inside, output shaft bearing 6 is obtained effectively lubricated.
