Abstract
The invention relates to a spline shaft easy to lubricate. The spline shaft comprises a shaft body. The lower end of the shaft body is provided with a spline section. An annular groove is formed in the portion, close to the upper end, of the side wall of the shaft body. A plurality of oil injection holes communicated with the bottom end of the shaft body are formed in the wall of the groove. An annular oil guide groove used for guiding lubricating oil flowing from the oil injection holes to the whole surface of the spline section is formed in the side wall of the spline section. A sealing ring is arranged in the groove in a sleeving mode, and the sealing ring is used for keeping the flatness of the surface of the shaft body and preventing the lubricating oil in the oil injection holes from flowing backwards out. No gap exists between the sealing ring and the inner wall of the groove. The outer surface of the sealing ring and the outer surface of the shaft body are located on the same arc face. According to the spline shaft easy to lubricate, by forming the oil injection holes communicated with the spline section in the oil injection groove and then by guiding the lubricating oil to the whole spline section through the oil guide groove, the oil injection efficiency is greatly improved, and oil injection is easier and more convenient.
Description
Technical field
The present invention relates to one and easily lubricate splined shaft.
Background technique
The current most structure of splined shaft is on the market simple; function singleness, when carrying out oiling to splined shaft by adding splined shaft on surface, but the effect of adding like this is slowly; and the area of bottom surface spline segment oiling is very uneven, oiling degree of difficulty is very large.
Summary of the invention
The technical problem to be solved in the present invention is: for solving above-mentioned Problems existing, provide one easily to lubricate splined shaft, solves the uneven and troublesome problem of oiling of common splined shaft oiling.
The technical solution adopted for the present invention to solve the technical problems is: one easily lubricates splined shaft, comprise axis body, axis body lower end has spline segment, the nearly upper end of axis body sidewall offers annular groove, groove walls offers the oil hole that several are connected with axis body bottom, spline segment sidewall offers the annular oil guide groove for the lubricant oil flowed down in oil hole being imported to whole spline segment surface, groove inner sleeve has for retainer shaft surface flatness and the seal ring that prevents from lubricant oil in oil hole from flowing backwards, very close to each other between seal ring and groove inner wall, seal ring outer surface and axis body outer surface are positioned at same cambered surface.
Further, in order to promote oil injecting speed, between axis body lower end and spline segment, there is compartmented.
Further, in order to spline segment largest outer diameter is identical with axis body outer diameter.
Further, conveniently oiling, spline segment minimum exterior diameter is identical with compartmented outer diameter.
The invention has the beneficial effects as follows, the oil hole that easy lubrication splined shaft of the present invention is connected by being provided with spline segment in oiling groove, then by oil guide slot, lubricant oil is directed to whole spline segment, greatly promote oiling efficiency, make oiling more simple and convenient.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation after the present invention installs seal ring.
1. axis bodies, 2. spline segment, 3. groove, 4. oil hole, 5. oil guide slot, 6. seal ring in figure.
Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
One as depicted in figs. 1 and 2 easily lubricates splined shaft, comprise axis body 1, axis body 1 lower end has spline segment 2, the nearly upper end of axis body 1 sidewall offers annular groove 3, groove 3 wall offers five oil holes 4 be connected with axis body 1 bottom, spline segment 2 sidewall offers the annular oil guide groove 5 for the lubricant oil flowed down in oil hole 4 being imported to whole spline segment 2 surface, groove 3 inner sleeve has for retainer shaft body 1 surface smoothness and the seal ring 6 that prevents from lubricant oil in oil hole 4 from flowing backwards, very close to each other between seal ring 6 and groove 3 inwall, seal ring 6 outer surface and axis body 1 outer surface are positioned at same cambered surface.
Further, in order to promote oil injecting speed, between axis body 1 lower end and spline segment 2, there is compartmented, further, in order to spline segment 2 largest outer diameter is identical with axis body 1 outer diameter, further, conveniently oiling, spline segment 2 minimum exterior diameter is identical with compartmented outer diameter, the oil hole 4 that easy lubrication splined shaft of the present invention is connected by being provided with spline segment 2 in oiling groove, by oil guide slot 5, lubricant oil is directed to whole spline segment 2 again, greatly promotes oiling efficiency, make oiling more simple and convenient.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to right.
