Abstract
The utility model belongs to engineering machinery, and relates to a shaft sleeve of a pin shaft of a mini-excavator. The inner wall of the shaft sleeve of the pin shaft is provided with a spiral oil groove, accordingly the lubrication between the pin shaft and the shaft sleeve is facilitated, lubricating oil is enabled to quickly reach the lubrication portion, and the hazards which damage the pin shaft and the shaft sleeve are eliminated. The shaft sleeve of the pin shaft of the mini-excavator can be used for pin shafts of various engineering machinery.
Description
Technical field
The utility model relates to a kind of bearing pin axle sleeve of excavator.
Background technique
The axle sleeve of excavator bearing pin is for the wearing and tearing that reduce bearing pin, and play an important role the working life that prolongs bearing pin, and the sleeve lining of existing bearing pin axle sleeve does not have tank structure, so can not make lubricant oil better arrive the lubricant housings.
Summary of the invention
The purpose of this utility model is, provides a kind of and open helical oil groove on the inwall of axle sleeve, can be good at making lubricant oil to arrive the lubricant housings, has eliminated because oil lubrication is not in place, and the dry friction that causes, damages the hidden danger of bearing pin and axle sleeve rapidly.Can improve the working life of axle and axle sleeve greatly.The utility model is just at a kind of helical oil groove of inwall cutting of axle sleeve, and is simple in structure, is convenient to processing.And can not cause the bearing pin axle sleeve of a kind of excavator of too much influence to the rigidity of axle sleeve.
Technical solution of the present utility model is such: a kind of bearing pin axle sleeve of excavator, comprise axle sleeve, and it is characterized in that opening helical oil groove on the inwall of axle sleeve.
The helical oil groove of axle sleeve has one or more.
The utility model has the advantages that at sleeve lining and open helical oil groove, can make lubricant oil arrive the lubricant housings smoothly, remove a hidden danger, can be fine prolongation bearing pin working life, and simple in structure, the axle sleeve that processing cost is low.
Description of drawings
It is such that structure of the present utility model constitutes;
Fig. 1 installs the main sectional view of looking for overall structure of the present utility model.
Fig. 2 presses the A-A sectional view of Fig. 1 for the utility model.
Among Fig. 1～Fig. 2, axle sleeve (1), helical oil groove (2).
Embodiment
Most preferred embodiment of the present utility model is such, referring to Fig. 1, Fig. 2, cuts out helical oil groove (2) on the ring inwall of axle sleeve (1), processes with boring, hook, sharp method.Helical oil groove (2) has more than the circle.But also can be on the sleeve lining at processing groove laterally or vertically.
The utility model only needs to cut helical oil groove (2) on inwall and gets final product on the basis of original axle sleeve.Realized that easily lubricant oil arrives the purpose of lubricant housings fast and effectively.
The utility model does not limit use on the bearing pin of hydraulic shovel, may also extend on the bearing pin of all kinds of engineering machinery.
Claims (2)
1. an excavator bearing pin axle sleeve comprises axle sleeve, it is characterized in that opening helical oil groove (2) on the inwall of axle sleeve (1).
2. according to the described a kind of excavator bearing pin axle sleeve of claim 1, it is characterized in that the helical oil groove (2) of axle sleeve (1) has one or more.
