Abstract
The utility model discloses a lubricated axle sleeve belongs to machine parts technical field, aims at providing the better axle sleeve of lubricated effect, and it has the lubrication hole to open on the axle sleeve, and the lubrication hole communicates with the axle sleeve, is equipped with the graphite cake in the lubrication hole and promotes the end cap, promotes the end cap and can push into in the axle sleeve with the graphite cake.
Description
Technical Field
The utility model relates to a machine parts, more specifically says that it relates to a lubricated axle sleeve.
Background
The shaft sleeve is a cylindrical mechanical part sleeved on the rotating shaft and is a component of the sliding bearing. The existing shaft sleeve is usually a tubular metal cylinder, the shaft is arranged in the shaft sleeve in a penetrating mode, lubricating oil is filled in front of the shaft and the shaft sleeve, and therefore friction between the shaft and the shaft sleeve is reduced, and the friction is reduced only through the lubricating oil and is far from insufficient.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model aims to provide a lubricated better axle sleeve of effect.
In order to achieve the above purpose, the utility model provides a following technical scheme:
a lubricating hole is formed in the shaft sleeve and communicated with the shaft sleeve, a graphite block and a pushing plug are arranged in the lubricating hole, and the pushing plug can push the graphite block into the shaft sleeve.
Furthermore, the lubricating hole is composed of a first hole body and a second hole body which are communicated with each other, the graphite block is arranged in the first hole body, the inner wall of the second hole body is provided with internal threads, the pushing plug is composed of a thread section and a rotating cap, the rotating cap is provided with a rotating groove, and the thread section is matched with the internal threads.
Furthermore, an extrusion sheet is arranged in the first hole body and is arranged between the graphite block and the threaded section.
Furthermore, the lubricating holes are provided with a plurality of lubricating holes which are arranged in the axial direction of the shaft sleeve in a staggered mode.
Further, the pressing sheet is made of a metal material.
By adopting the technical scheme, the beneficial effects of the utility model are that:
when the shaft sleeve is arranged on the shaft rod, the graphite block in the lubricating hole is pressed against the shaft rod under the extrusion of the pushing plug, so that the shaft rod and the shaft sleeve are lubricated; and a plurality of lubrication holes of evenly arranging are arranged in the length direction of axle sleeve for the lubricated area increase of axle sleeve and axostylus axostyle realizes more comprehensive lubrication, further promotes lubricated effect.

Fig. 2 is a schematic sectional view of the shaft sleeve.
Fig. 3 is an exploded view of the bushing.
Detailed Description
Embodiments of the present invention are further described with reference to fig. 1 to 3.
The utility model provides a following technical scheme: the shaft sleeve 1 is provided with a lubricating hole 2, the lubricating hole 2 is communicated with the shaft sleeve 1, a graphite block 3 and a pushing plug 4 are arranged in the lubricating hole 2, and the pushing plug 4 can push the graphite block 3 into the shaft sleeve 1; the lubricating hole 2 is composed of a first hole body 201 and a second hole body 202 which are communicated with each other, the graphite block 3 is arranged in the first hole body 201, an internal thread 203 is arranged on the inner wall of the second hole body 202, the pushing plug 4 is composed of a thread section 401 and a rotating cap 402, a rotating groove 403 is formed in the rotating cap 402, and the thread section 401 is matched with the internal thread 203; an extrusion sheet 5 is arranged in the first hole body 201, the extrusion sheet 5 is made of metal materials, and the extrusion sheet 5 is arranged between the graphite block 3 and the threaded section 401; the lubricating holes 2 are provided with a plurality of lubricating holes which are arranged in the axial direction of the shaft sleeve 1 in a staggered way.
The working principle is as follows: the graphite has a good lubricating effect on the space between the shaft lever and the shaft sleeve 1, and the graphite block 3 can be pushed to move towards the direction of the shaft lever and abut against the shaft lever by rotating the pushing plug 4; the shaft lever rubs against the graphite block 3 when rotating, and the graphite block 3 can realize the lubrication between the shaft lever and the shaft sleeve 1; after the shaft rod works for a long time and is rubbed with the graphite block 3, and the graphite block 3 is worn, the shaft rod continues to rotate to push the plug 4, and the graphite block 3 is pushed to be abutted against the shaft rod again, so that the lubrication of the shaft rod and the shaft sleeve 1 is continuously realized, and the service lives of the shaft sleeve 1 and the shaft rod are prolonged;
a screwdriver or other works are inserted into the rotating groove 403, and the work rotates to drive the rotating cap 402 to rotate, so that the threaded section 401 moves towards the graphite block 3, the threaded section 401 pushes the extrusion sheet 5, and the extrusion sheet 5 pushes the graphite block 3 to move towards the shaft sleeve 1;
the arrangement of the extrusion piece 5 ensures that the graphite block 3 is not easily damaged when the plug 4 is pushed to rotate and the graphite block 3 is pushed.
The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and the skilled in the art can carry out the common changes and replacements within the technical solution of the present invention.
Claims (2)
