AI Technical Summary

Problems solved by technology

In this way, serious problems will arise, and the cost of parts and assembly will have to increase
In addition, the use of a pump in the lubricating oil supply device causes a problem that the production cost is higher than that of a lubricating oil supply device using an insert due to its complicated structure.
Also, due to the large amount of machining required on the inner surface of the opening, there are also problems related to maintaining the strength of the rotating shaft (for example, the outer diameter of the shaft needs to be increased, or the corners of the inner surface need to be smoothed)

Abstract

An axially extending lubricating oil supply hole 21 is provided in a rotating shaft 20 rotatably supported on a case 10, and lubricating oil is supplied into the lubricating oil supply hole 21 from a lubricating oil path formed in the case 10 through a guide member 80. The guide member 80 has a pipe-shaped portion which protrudes into the lubricating oil supply hole 21, and a spiral structure is formed on an outer circumferential surface of the pipe-shaped portion for leading lubricating oil rotated by operating together with the rotation of the rotating shaft 20 deeper into the lubricating oil supply hole 21.

Description

technical field [0001] The present invention relates to a lubricating oil supply device for in-shaft lubrication for supplying lubricating oil from a lubricating oil path formed in a housing to a lubricating oil supply hole in the axial direction of a rotating shaft. Background technique [0002] An automotive gearbox is a device with a lubricating oil supply similar to that described. overall as Image 6 shown (see also figure 2 ) of the automobile gearbox has: a main shaft 20, which is rotatably supported on the gearbox housing 10, for receiving the rotational driving force transmitted from the engine; and an intermediate shaft 30, which is parallel to the main shaft 20. The gears 51 to 55, 61 to 66, which are constantly meshing with each other, are located on the main shaft 20 and the intermediate shaft 30. The main shaft 20 is then connected in a synchronous manner with a gear of a predetermined speed by any synchromesh mechanism 71 to 73 mounted thereon. . [0003] ...
