Abstract

(57) [Summary] [Purpose] Removing contaminants from the lubricating oil supplied to the bearings,
Improve bearing life. [Structure] An oil sump 2 for collecting lubricating oil picked up by gears is installed in a housing 1, and lubricating oil flowing out from the oil sump 2 to an oil hole 3 is guided by an oil channel 5 and provided on a shaft 4. The hollow passage 6 supplies the bearing. By incorporating a filter material 7 in the oil sump 2, removing contaminants of lubricating oil by the filter material 7, and supplying clean lubricating oil to the bearing, the life of the bearing is improved.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a lubricating oil supply device, and more particularly to a device for supplying lubricating oil to a shaft supporting bearing in a transmission of an automobile.

[0002]

[Prior Art]

 A conventional supply device for supplying lubricating oil to a needle bearing for a transmission gear in a transmission of an automobile will be described with reference to FIG. 1 showing the present invention. The housing 1 stores the lubricating oil lifted by a gear. The oil reservoir 2 is provided, and the lubricating oil in the oil reservoir 2 passes from the oil hole 3 formed in the housing 1 to the outside of the oil channel 5 installed at the end of the shaft 4, and then to the inside of the oil channel 5. Through the hollow passage 6 of the shaft 4 to lubricate a speed change gear needle bearing (not shown).

[0003]

[Problems to be solved by the device]

 By the way, the lubricating oil in the transmission contains dirt and wear powder of gears.In the above-mentioned conventional supply device, dirt and wear powder of gears flow to the needle bearing together with the lubricating oil, and the bearing life is shortened. There is a problem of having an adverse effect.

In view of this, the present invention provides a lubricating oil supply device capable of supplying to the bearing in a state in which contaminants such as dirt and abrasion powder of gears mixed in the lubricating oil have been removed, thereby extending the life of the bearing. The task is to do.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention proposes a method in which the lubricating oil picked up by gears is collected in an oil sump, and the lubricating oil in this oil sump is supplied to the bearing through an oil supply passage. In the oil supply device, a structure in which a filter material is incorporated in the oil sump is adopted.

[0006]

[Action]

 Lubricating oil picked up by gears and stored in the oil sump is filtered by a filter material to remove mixed dirt and wear particles of gears, thus not affecting bearing life. Lubricating oil can be supplied.

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in the figure, an oil sump 2 for accommodating the lubricating oil lifted up by gears is provided inside the housing 1 of the transmission, and a filter material 7 is incorporated in the bottom of this oil sump 2. Has been.

The oil channel 3 formed between the oil hole 3 formed in the housing 1 so as to communicate with the oil sump 2 and the middle air passage 6 of the shaft 4 is fixed to the outer ring of the bearing 8 that supports the shaft 4 and the bearing. 8 has a cross-sectional shape in which a cylindrical portion 5b that fits into the hollow passage 6 of the shaft 4 is provided continuously on the inner periphery of the annular plate 5a that closes one end surface of the annular plate 5a, and is formed between the opposed faces of the annular plate 5a and the housing 1. The lubricating oil is guided from the oil hole 3 to the hollow passage 6 at the inner periphery of the passage 9 and the cylindrical portion 5b.

In the illustrated case, a filter seal 10 is attached to the other end of the bearing 8 so that the lubricating oil splashed by a gear is supplied into the bearing 8 through the filter seal 10.

The filter material 7 incorporated in the oil sump 2 is made of any material as long as it has a function of filtering the lubricating oil and removing dirt and gear abrasion powder mixed in the lubricating oil. Can be freely selected.

The lubricating oil supply device of the present invention is configured as described above, and when the lubricating oil scraped up by the gears is collected in the oil sump 2 during operation of the transmission, this oil sump 2 Filtered by the filter material 7 incorporated in the filter, mixed contaminants and tooth wear powder are removed by this filter material 7, and only lubricating oil that does not adversely affect the bearing flows out from the oil hole 3, It is guided in the channel 5 and fed into the needle bearing through the hollow passage 6 of the shaft 4. Lubricating oil is also supplied to the bearing 8 through the gap 11 between the shaft inner diameter and the cylindrical portion 5b of the oil channel 5.

As described above, by incorporating the filter material 7 into the oil sump 2, the dirt mixed with the lubricating oil, the abrasion powder of the gears, etc. are surely removed, and the needle bearing and the shaft support bearing are supported. Therefore, clean lubricating oil can be supplied, and premature separation of the bearing can be prevented.

[0014]

【effect】

 As described above, according to the present invention, since the filter material is incorporated in the oil sump that collects the lubricating oil picked up by the gears, it is possible to remove dirt mixed with the lubricating oil, wear powder of the gears, etc. The bearing life can be improved by cleaning the lubricating oil supplied to the bearing.
