Abstract
The invention discloses a shaft sleeve with a helical oil groove of an excavating machine. The shaft sleeve with the helical oil groove of the excavating machine comprises the shaft sleeve and the helical oil groove and is characterized in that the helical oil groove is arranged in the inner wall of the shaft sleeve of a pin shaft to be convenient for the lubrication between the pin shaft and the shaft sleeve. Lubricating oil can quickly reach a lubrication part, the hidden danger of damaging the pin shaft and the shaft sleeve is eliminated, the abrasion between the shaft and the shaft sleeve is reduced, a contact surface is lubricated, and the service life of the shaft sleeve is prolonged. The shaft sleeve can be used on the pin shafts of various kinds of engineering machinery.
Description
Technical field
The present invention relates to a kind of axle sleeve of excavator band helical oil groove.
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 objective of the invention is to reduce the axle sleeve wearing and tearing, increase the service life, provide a kind of inwall at axle sleeve to open helical oil groove, can be good at making lubricant oil to arrive the lubricant housings, 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 present invention 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 axle sleeve of a kind of excavator band helical oil groove of too much influence to the rigidity of axle sleeve.
Technical solution of the present invention is such: a kind of axle sleeve of excavator band helical oil groove, comprise axle sleeve, helical oil groove, and it is characterized in that opening helical oil groove on the inwall of axle sleeve.
The helical oil groove of axle sleeve has more than the groove.
The helical oil groove oiler of axle sleeve is at the aperture of axle sleeve end face.
The present invention's advantage compared with prior art is: open helical oil groove at sleeve lining, 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 invention constitutes:
Fig. 1 installs the main sectional view of looking for overall structure of the present invention.
Fig. 2 presses the A-A sectional view of Fig. 1 for the present invention.
Reference character: axle sleeve (1), helical oil groove (2).
Embodiment
Below in conjunction with accompanying drawing the present invention is further described:
Embodiment `1 cuts out helical oil groove (2) at 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 at processing groove laterally or vertically on the sleeve lining.
Embodiment `2 at axle sleeve (1) endoporus limit wall processing vertical bar shaped oil groove, to improve flowability, reduces pressure, and right to use axle contacts with axle sleeve and has more lubricity.
Embodiment `3 bores an oilhole in axle sleeve (1) neutral position, lubricating oil between flowing into by oilhole oil reaches lubrication effect too.
The present invention only needs to cut helical oil groove (2) at 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 present invention 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 (3)
1. the axle sleeve of an excavator band helical oil groove comprises axle sleeve, helical oil groove, it is characterized in that opening helical oil groove (2) on the inwall of axle sleeve (1).
2. according to the axle sleeve of the described a kind of excavator band helical oil groove of claim 1, it is characterized in that the helical oil groove (2) of axle sleeve (1) has more than the groove.
3. according to the axle sleeve of the described a kind of excavator band helical oil groove of claim 1, it is characterized in that helical oil groove (2) oiler of axle sleeve (1) is at the aperture end face of axle sleeve (1).
