Specific examples of the present invention will be described in further detail below. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.

As shown in fig. 1 to fig. 3, it is a schematic structural diagram of a steel shaft sleeve with an oil groove arrangement structure suitable for reciprocating translation provided by the present invention. The steel bushing with an oil groove arrangement adapted for reciprocating translation comprises a first bushing segment 10, a second bushing segment 20 arranged at one end of the first bushing segment 10, and a third bushing segment 30 arranged at the other end of the first bushing segment 10. The steel shaft sleeve with the oil groove arrangement structure suitable for reciprocating translation is made of steel, such as 45 steel. In addition, the thickness and diameter of the steel bushing having the oil groove arrangement structure adapted for the reciprocating translation should be designed according to the application, and thus, in the present embodiment, the thickness and diameter are not particularly limited. It is contemplated that the steel sleeve having the oil groove arrangement adapted for reciprocating translation may also include other functional structures, such as inner and outer chamfers, etc., which are well known to those skilled in the art and will not be described herein.

The first shaft sleeve section 10 comprises an annular oil storage groove 11 formed in the inner wall of the first shaft sleeve section 10 and at least two oil filling holes 12 formed in the annular oil storage groove 11. The annular oil storage groove 11 is arranged on the inner wall of the first shaft sleeve 10 and is used for storing lubricating oil injected from the two oil injection holes 11 and receiving surplus lubricating oil in the using process so as to achieve the purposes of fully lubricating and saving the lubricating oil. The number of the oil holes 11 may be more, such as four. In the present embodiment, only two of the oil holes 12 are provided as an example. The diameter of the two oil holes 12 can be between 5 mm and 8 mm. The two oil holes 12 are symmetrically arranged in a plane passing through the central axis of the first sleeve 10, and the central axes of the two oil holes 12 are aligned, so that the annular oil storage tank 11 can be filled with the injected lubricating oil more quickly.

The second sleeve section 20 includes a body 21, a first oil reservoir 22 formed in an inner wall of the body 21, and a second oil reservoir 23 formed in an inner wall of the body 21. The second sleeve portion 20 is formed integrally with the first sleeve portion 10. The body 21 is a hollow cylinder structure, one end of which is connected to the first sleeve section 10, and specifically, the body 21 and the second sleeve 20 are integrally formed. First oil storage tank 22 with the one end intersection of second oil storage tank 23 and intercommunication, the other end with annular oil storage tank 11 intercommunication has thereby realized being linked together between annular oil storage tank 11, first oil storage tank 22 to and the second oil storage tank 23, to do benefit to lubricating oil and flow in first, second

oil storage tank

22, 23. In the unfolded state of the steel bushing, the first oil storage tank 22 and the second oil storage tank 23 are distributed in a splayed shape and are arranged on the inner wall of the body 21, and the opening direction of the first oil storage tank is towards the first bushing 10, so that the oil in the annular oil storage tank 11 can flow from the opening ends of the first oil storage tank 22 and the second oil storage tank 23 to the closing ends of the first oil storage tank 22 and the second oil storage tank 23 or reversely flow. In the expanded view of the second sleeve section 20, an included angle α between the first oil storage groove 22 and the second oil storage groove 23 is an obtuse angle and is in arc transition, and the obtuse angle is smaller than 140 degrees and larger than 110 degrees, so that the lubricating oil is uniformly distributed on the inner side wall of the second sleeve section 20. In the expanded view of the second sleeve section 20, an included angle β between the extending directions of the first oil storage groove 22 and the second oil storage groove 23 and the annular oil storage groove 11 of the first sleeve section 10 is an acute angle, which is smaller than 50 degrees and larger than 30 degrees, so that when the shaft is translated in the second sleeve section 20 in a reciprocating manner, the lubricating oil stored in the annular oil storage groove 11 can be sequentially introduced into the first oil storage groove 22 and the second oil storage groove 23, so that when the shaft is moved in the second sleeve section 20 in a reciprocating manner, the lubricating oil can flow along the first oil storage groove 22 and the second oil storage groove 23 under the driving of the shaft, thereby achieving sufficient lubrication of the shaft and the sleeve. The cross sections of the first oil storage groove 22 and the second oil storage groove 23 are semicircular, so that the stress concentration phenomenon at the bottoms of the first oil storage groove 22 and the second oil storage groove 23 is avoided.

The third bearing sleeve section 30 has the same structure, size and function as the second bearing sleeve section 20, and is integrally formed with the first bearing section 10. The third bearing segment 30 is provided with third and fourth

oil storage grooves

32, 33, but the third and fourth

oil storage grooves

oil storage grooves

22 and 23, so as to squeeze the lubricating oil from the lower part of the shaft to the upper part of the shaft, thereby achieving the purpose of fully lubricating the shaft and the second bearing section 20, meanwhile, the shaft will drive the lubricating oil to flow along the closed ends to the open ends of the third and fourth

oil storage grooves

32 and 33, and in the flowing process, the shaft and the third bearing section 30 will be lubricated. The flow direction of the lubricating oil is exactly opposite when the shaft moves towards the third bearing segment 30, so that a sufficient lubrication effect is achieved when the shaft reciprocates in the steel bearing.

Compared with the prior art, the utility model provides a pair of steel axle sleeve with oil groove structure of arranging suitable for reciprocal translation is through the design first oil storage tank 22 and second oil storage tank 23's structure in second axle sleeve section 20, specifically under the expansion state of steel axle sleeve first oil storage tank 22 with second oil storage tank 23 is the splayed and distributes and sets up 21 inner walls of body and opening direction orientation first axle sleeve 10, the closed end setting of first, second

oil storage tank
