Abstract
The utility model discloses a pin shaft sleeve of an excavator, which comprises a shaft sleeve main body and a cylindrical section at one end of the shaft sleeve main body, wherein a spiral groove is formed in the surface of the shaft sleeve main body, and an oil inlet is formed in the spiral groove; the novel oil-saving type shaft sleeve is characterized in that an oil outlet structure communicated with the spiral groove is arranged inside the shaft sleeve main body, and a plurality of oil outlets are formed in the oil outlet structure. The beneficial effects of the utility model are as follows: the problem of the too concentrated lubrication that leads to of oil yield is solved, the design of arc indent and oil-out is adopted for it is even to get the oil point dispersion, can lubricate fast.
Description
Technical Field
The utility model relates to the technical field of excavator accessories, in particular to an excavator pin shaft sleeve.
Background
The shaft sleeve is one of common accessories in industrial production, and has wide application, and is also commonly found in accessories of an excavator, and Chinese patent publication No. CN202012571U discloses a 'pin shaft sleeve of an excavator', which is provided with a spiral oil groove on the inner wall of the pin shaft sleeve, so that lubrication between the pin shaft and the shaft sleeve is facilitated, lubricating oil can well reach lubrication parts rapidly, and hidden danger of damaging the pin shaft and the shaft sleeve is eliminated.
However, the above patent also has a problem that the lubrication oil is too concentrated at one point, resulting in insufficient lubrication efficiency and insufficient lubrication uniformity.
Disclosure of Invention
The utility model aims to provide an excavator pin shaft sleeve which solves the problems in the background art.
In order to achieve the above purpose, the present utility model provides the following technical solutions:
the pin shaft sleeve of the excavator comprises a shaft sleeve main body and a cylindrical section at one end of the shaft sleeve main body, wherein a spiral groove is formed in the surface of the shaft sleeve main body, and an oil inlet is formed in the spiral groove;
the novel oil-saving type shaft sleeve is characterized in that an oil outlet structure communicated with the spiral groove is arranged inside the shaft sleeve main body, and a plurality of oil outlets are formed in the oil outlet structure.
Further, the oil outlet structure comprises an arc-shaped indent and an oil inlet channel, the arc-shaped indent is formed in the inner wall of the shaft sleeve main body, the oil inlet channel is formed in the arc end of the arc-shaped indent, the oil inlet channel is connected with the oil inlet, and the oil outlet is formed in the arc-shaped indent.
Further, at least six arc-shaped concave parts are arranged.
Further, at least two spiral grooves are formed.
The beneficial effects of the utility model are as follows:
the problem of the too concentrated lubrication that leads to of oil yield is solved, the design of arc indent and oil-out is adopted for it is even to get the oil point dispersion, can lubricate fast.
Drawings
FIG. 1 is a schematic diagram of the structure of the present utility model;
FIG. 2 is a schematic view of an arcuate concave shape according to the present utility model;
fig. 3 is a schematic view of an oil outlet of the present utility model.
Detailed Description
The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.
Example 1, please refer to fig. 1:
the utility model provides an excavator round pin axle sleeve, includes axle sleeve main part 2 and the cylinder section 1 of one end thereof, has seted up two spiral groove 3 on axle sleeve main part 2 surface, in order to be convenient for advance oil, sets up oil inlet 4 at spiral groove 3.
As shown in fig. 2-3:
in order to facilitate more uniform oil discharge, an oil discharge structure communicated with the spiral groove 3 is arranged inside the shaft sleeve main body 2;
the oil outlet structure comprises arc-shaped concave parts 5 and oil inlet channels 6, wherein the arc-shaped concave parts 5 are formed in the inner wall of the shaft sleeve main body 2, at least six arc-shaped concave parts 5 are formed in annular arrangement, the oil inlet channels 6 are formed in the arc ends of the arc-shaped concave parts 5, the oil inlet channels 6 are connected with the oil inlet 4, and the oil outlet 501 is formed in the arc-shaped concave parts 5.
The use principle is as follows:
lubricating oil enters through the oil inlet 4, passes through the oil inlet channel 6 and finally is dispersed through the oil outlet 501, so that the oil outlet is more uniform.
Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
