Abstract
The utility model relates to an oil-retaining bearing, comprising: the middle part of the shaft sleeve is provided with an inner ring for the rotating shaft to pass through; the first oil storage tank is arranged on the outer wall of the shaft sleeve along the top of the shaft sleeve; the second oil storage tank is rotatably arranged with the first oil storage tank and is arranged on the outer wall of the shaft sleeve; the first oil storage tank and the second oil storage tank are consistent in structure and are provided with arc-shaped lower concave parts; the shaft sleeve in the scheme needs to be vertically installed, namely the axis of the shaft sleeve is parallel to a vertical line, but in the rotating process of the rotating shaft, thrown lubricating liquid can enter a concave part of the first oil storage tank or the second oil storage tank and then wets the shaft sleeve again; thereby reducing the loss of the lubricating liquid and prolonging the service life of the bearing.
Description
Technical Field
The utility model relates to a bearing, in particular to an oil-retaining bearing.
Background
The shaft sleeve is an important element in mechanical design, the shaft sleeve is usually sleeved on the rotating shaft to play a role in protecting the rotating shaft, lubricating and replacing liquid can be thrown out from a gap between the rotating shaft and an inner ring of the shaft sleeve in the using process of the shaft sleeve, and the lubricating liquid can be slowly reduced in the long-term using process, so that the lubricating performance between the rotating shaft and the shaft sleeve is influenced;
in conclusion, how to reduce the loss of the lubricating fluid and prolong the service life of the bearing becomes a problem which needs to be solved urgently by researchers in the field.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the utility model is as follows: how to reduce the loss of the lubricating liquid and prolong the service life of the bearing;
in order to solve the technical problems, the utility model adopts the following technical scheme:
the present invention is an oil-impregnated bearing comprising: the middle part of the shaft sleeve is provided with an inner ring for the rotating shaft to pass through; the first oil storage tank is arranged on the outer wall of the shaft sleeve along the top of the shaft sleeve; the second oil storage tank is rotatably arranged with the first oil storage tank and is arranged on the outer wall of the shaft sleeve; the first oil storage tank and the second oil storage tank are consistent in structure and are provided with arc-shaped lower concave parts;
the shaft sleeve in the scheme needs to be vertically installed, namely the axis of the shaft sleeve is parallel to a vertical line, but in the rotating process of the rotating shaft, thrown lubricating liquid can enter a concave part of the first oil storage tank or the second oil storage tank and then wets the shaft sleeve again;
it should be noted that the shaft sleeve is of a rotational symmetric structure, and only one oil storage groove plays a role in storing oil in the use process of the shaft sleeve.
In order to further collect thrown lubricating liquid, the top and the bottom of the inner ring are both flared;
thus, the thrown lubricating liquid can reenter into the gap between the transmission shaft and the bearing from the flaring part.
In order to limit the shaft sleeve during installation, the bottom of the outer wall of the shaft sleeve is provided with an outer chamfer; a limiting plane is arranged on the outer chamfer angle line in an extending mode, and the limiting plane and the outer chamfer angle are arranged in an obtuse angle mode;
in this scheme, the installation of bearing of being convenient for is set up outer chamfer, sets up spacing plane when locating part and spacing plane offset, has restricted the axial motion of axle sleeve.
The utility model has the beneficial effects that: the utility model relates to an oil-retaining bearing.A shaft sleeve in the scheme needs to be vertically installed, namely the axis of the shaft sleeve is parallel to a vertical line, but in the rotating process of a rotating shaft, thrown lubricating liquid can enter a concave part of a first oil storage tank or a second oil storage tank and then re-infiltrate the shaft sleeve; thereby reducing the loss of the lubricating liquid and prolonging the service life of the bearing.

The utility model is further illustrated with reference to the following figures and examples.
FIG. 1 is a cross-sectional view of the present invention;
FIG. 2 is a top view of the present invention;
FIG. 3 is an enlarged view of FIG. 1A;
in the figure: 1-shaft sleeve, 2-inner ring, 3-first oil storage tank, 4-second oil storage tank, 5-lower concave part, 6-flaring arrangement, 8-outer chamfer and 9-limiting plane.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.
As shown in fig. 1-2, the present invention is an oil-impregnated bearing comprising: the middle part of the shaft sleeve 1 is provided with an inner ring 2 for the rotating shaft to pass through; the first oil storage tank 3 is arranged on the outer wall of the shaft sleeve 1 along the top of the shaft sleeve downwards; a second oil storage tank 4 which is rotatably arranged with the first oil storage tank 3 and is opened on the outer wall of the shaft sleeve 1; wherein, the first and second oil storage tanks 3, 4 have the same structure and are provided with an arc-shaped lower concave part 5;
the shaft sleeve in the scheme needs to be vertically installed, namely the axis of the shaft sleeve is parallel to a vertical line, but in the rotating process of the rotating shaft, thrown lubricating liquid can enter a concave part of the first oil storage tank or the second oil storage tank and then wets the shaft sleeve again;
it should be noted that the shaft sleeve is of a rotational symmetric structure, and only one oil storage groove plays a role in storing oil in the use process of the shaft sleeve.
As shown in fig. 1, in order to further collect thrown lubricating liquid, the top and bottom of the inner ring 2 are both flared openings 6;
thus, the thrown lubricating liquid can reenter into the gap between the transmission shaft and the bearing from the flaring part.
As shown in fig. 3, in order to limit the shaft sleeve during installation, the bottom of the outer wall of the shaft sleeve 1 is provided with an outer chamfer 8; a limiting plane 9 extends on the line of the outer chamfer 8, and the limiting plane 9 and the outer chamfer 8 are arranged in an obtuse angle;
in this scheme, the installation of bearing of being convenient for is set up outer chamfer, sets up spacing plane when locating part and spacing plane offset, has restricted the axial motion of axle sleeve.
The utility model relates to an oil-retaining bearing.A shaft sleeve in the scheme needs to be vertically installed, namely the axis of the shaft sleeve is parallel to a vertical line, but in the rotating process of a rotating shaft, thrown lubricating liquid can enter a concave part of a first oil storage tank or a second oil storage tank and then re-infiltrate the shaft sleeve; thereby reducing the loss of the lubricating liquid and prolonging the service life of the bearing.
In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations can be made by the worker in the light of the above teachings without departing from the spirit of the utility model. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
