Embodiment Construction

[0013] The present invention will now be described in further detail with reference to the drawings. These drawings are all simplified schematic diagrams, which merely illustrate the basic structure of the present invention in a schematic manner, so they only show the structures related to the present invention.

[0014] Such as figure 1 with figure 2 An easy-to-lubricate spline shaft shown includes a shaft body 1, a spline section 2 is provided at the lower end of the shaft body 1, an annular groove 3 is formed on the proximal end of the side wall of the shaft body 1, and the wall of the groove 3 is provided with five and The bottom end of the shaft body 1 is connected with an oil hole 4, the side wall of the spline section 2 is provided with an annular oil guide groove 5 for guiding the lubricating oil flowing down from the oil hole 4 to the entire surface of the spline section 2. The groove 3 is sleeved There is a sealing ring 6 used to maintain the surface flatness of the s...

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 [0001] The invention relates to an easy lubrication spline shaft. Background technique [0002] At present, most of the spline shafts on the market have simple structure and single function. When oiling the spline shaft, the spline shaft is added on the surface, but the effect of this addition is very slow, and the area of ​​the bottom spline section is very different. Even, oil injection is very difficult. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide an easy-lubricated spline shaft to solve the above-mentioned existing problems, and solve the problems of uneven oil filling and troublesome oil filling of ordinary spline shafts. [0004] The technical solution adopted by the present invention to solve the technical problem is: an easy-lubricating spline shaft, comprising a shaft body, the lower end of the shaft body has a spline section, the proximal end of the side wall of the shaft body is provided with...
