Description

Technical Field

[0001] The utility model relates to the technical field of bearing bushes, and more specifically, the utility model relates to an adjustable bearing bush. Background Art

[0002] The existing bearing bush can protect and lubricate the sliding bearing. When the sliding bearing works, a very thin oil film is required between the bearing bush and the rotating shaft for lubrication. However, the existing bearing bush is not easy to adjust and cannot control the amount of the internal lubricating liquid, resulting in poor lubrication. As a result, there is direct friction between the bearing bush and the rotating shaft, and the friction will generate a very high temperature. Although the bearing bush is made of a special high-temperature resistant alloy material, the high temperature generated by the direct friction is still sufficient to burn it out, reducing the service life of the bearing bush and the bearing.

[0003] Among them, the patent with the publication number CN211501351U discloses an adjustable bearing bush, which includes a bearing seat, a fixed bearing bush and a lubrication mechanism. The inner end face of the bearing seat is fixedly clamped with a fixed bearing bush for support, and the bearing seat includes a bearing seat housing, a positioning groove, a fixing plate and a connecting hole. The inner end face of the bearing seat housing is symmetrically provided with positioning grooves for positioning;

[0004] When this structure is in use, the outside of the bearing can be in contact with the lubricating block inside the lubrication mechanism. The lubricating block can quickly lubricate the outside of the bearing. At the same time, the bearing can axially elastically extrude the lubricating block through a spring. At this time, since the inside of the bearing bush housing is filled with lubricating liquid, the excess lubricating liquid can overflow through the oil injection hole, improving the lubrication efficiency. However, this structure is not easy to adjust to an appropriate position during use, resulting in the device being unable to adapt to bearings of different sizes during use, and the adaptability of the device during use is low. Summary of the Utility Model

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides an adjustable bearing bush, aiming to solve the problems raised in the above background art.

[0006] The utility model provides the following technical solutions: an adjustable bearing bush, including a limiting cylinder, and limiting components are arranged at both ends of the limiting cylinder;

[0007] The limiting component includes an elastic support plate arranged at one end of the limiting cylinder. A plurality of positioning clamping plates for limiting are distributed in the middle of the elastic support plate, and a dislocation cavity is formed between two adjacent positioning clamping plates. Absorbent cotton is sleeved outside each of the plurality of positioning clamping plates;

[0008] One side of the positioning clamping plate is provided with an adaptation groove, a plurality of positioning holes are arranged on the inner wall of the adaptation groove, and support ball sockets are arranged in each of the positioning holes;

[0009] It can be seen that in the above technical solution, when the positioning clamping plates approach each other, they will squeeze the dislocation cavity, making it easy for the positioning clamping plates to approach each other, facilitating the clamping of the bearing. At the same time, by adjusting the positioning clamping plates to approach and spread towards the locking sleeve, bearings of different sizes can be accommodated. And when the positioning clamping plates clamp the bearing, the supporting ball holder can abut against the outer side of the bearing, which can not only ensure the stability of the bearing installation but also prevent the positioning clamping plates from contacting the bearing and causing the bearing to be unable to rotate, realizing the function of reducing friction;

[0010] On one side of the surface of the adaptation groove, a dislocation arc groove is opened. The vertical cross-sectional shape of the dislocation arc groove is set as an arc, and one end of the dislocation arc groove extends to the end of the positioning clamping plate. Elastic support plates are arranged at one ends of the plurality of positioning clamping plates. The elastic support plates are all inclined, and one ends of the support plates all extend to the end of the limiting cylinder. The vertical cross-sectional shape of the locking sleeve is set as a cone. A locking sleeve is arranged on the outer side of the positioning clamping plate, and one end of the locking sleeve extends to the end of the positioning clamping plate. The vertical cross-sectional shapes of the positioning hole and the supporting ball holder are both set as hemispherical. The supporting ball holder is rotationally connected with the positioning hole. An internal thread sleeve is arranged on the inner wall of the positioning clamping plate, and the internal thread sleeve is threadedly connected with the positioning clamping plate;

[0011] It can be seen that in the above technical solution, by rotating the locking sleeve, when the locking sleeve rotates, it drives the internal thread sleeve to rotate. The internal thread sleeve is threadedly connected with the positioning clamping plate and cooperates with the conical cross-section of the locking sleeve, so that when the locking sleeve displaces, it pulls each positioning clamping plate towards the center point of the locking sleeve, and then makes each positioning clamping plate approach each other to clamp the bearing.

[0012] The technical effects and advantages of the present utility model:

[0013] By setting the limiting component, compared with the prior art, the overall design is simple and the structure is reasonable. Through the corresponding cooperation of each structure, the internal thread sleeve is threadedly connected with the positioning clamping plate and cooperates with the conical cross-section of the locking sleeve, so that when the locking sleeve displaces, it pulls each positioning clamping plate towards the center point of the locking sleeve, and then makes each positioning clamping plate approach each other to clamp the bearing;

[0014] By adjusting the positioning clamping plates to approach and spread towards the locking sleeve, bearings of different sizes can be accommodated. And when the positioning clamping plates clamp the bearing, the supporting ball holder can abut against the outer side of the bearing, which can not only ensure the stability of the bearing installation but also prevent the positioning clamping plates from contacting the bearing and causing the bearing to be unable to rotate, realizing the function of reducing friction.

Specific embodiments

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] As shown in the attached Figures 1-4An adjustable bearing bush shown, through the limiting component arranged on the limiting cylinder, through the threaded connection between the internal thread sleeve and the positioning clamping plate and the conical section of the locking sleeve, when the locking sleeve displaces, it pulls each positioning clamping plate to gather towards the center point of the locking sleeve, and then makes each positioning clamping plate approach each other to clamp the bearing. At the same time, when each positioning clamping plate approaches each other, it will squeeze the dislocation cavity, which is easy for the positioning clamping plates to approach each other, convenient for clamping the bearing. At the same time, it can be adjusted by the way that each positioning clamping plate approaches and spreads towards the locking sleeve, and can adapt to bearings of different sizes. And when the positioning clamping plate clamps the bearing, the supporting ball holder can abut against the outside of the bearing, which can not only ensure the stability of the bearing installation but also avoid the contact between the positioning clamping plate and the bearing causing the bearing unable to rotate, realizing the function of reducing friction, and the specific structure of the component is as follows;

[0023] The limiting component includes an elastic support plate arranged at one end of the limiting cylinder. A number of positioning clamping plates for limiting are distributed in the middle of the elastic support plate, and a dislocation cavity is formed between each adjacent two positioning clamping plates. Absorbent cotton sleeves are sleeved on the outer sides of the multiple positioning clamping plates;

[0024] One side of the positioning clamping plate is provided with an adaptation groove. A number of positioning holes are arranged on the inner wall of the adaptation groove, and a supporting ball holder is arranged in each positioning hole.

[0025] One side of the surface of the adaptation groove is provided with a dislocation arc groove. The vertical cross-sectional shape of the dislocation arc groove is set as an arc, and one end of the dislocation arc groove extends to the end of the positioning clamping plate. Elastic support plates are arranged at one ends of the multiple positioning clamping plates. The elastic support plates are all inclined, and one end of each support plate extends to the end of the limiting cylinder. The vertical cross-sectional shape of the locking sleeve is set as a cone. The locking sleeve covers the outside of the positioning clamping plate, and one end of the locking sleeve extends to the end of the positioning clamping plate. The vertical cross-sectional shapes of the positioning hole and the supporting ball holder are both set as hemispherical. The supporting ball holder is rotationally connected with the positioning hole. An internal thread sleeve is arranged on the inner wall of the positioning clamping plate, and the internal thread sleeve is threadedly connected with the positioning clamping plate.

[0026] When in use according to the above structure, the staff installs the device at the designated position. When supporting the bearing, the bearing is placed between each positioning clamping plate. By rotating the locking sleeve, when the locking sleeve rotates, it drives the internal thread sleeve to rotate. The internal thread sleeve is threadedly connected with the positioning clamping plate and the conical section of the locking sleeve is combined, so that when the locking sleeve displaces, it pulls each positioning clamping plate to gather towards the center point of the locking sleeve, and then makes each positioning clamping plate approach each other to clamp the bearing;

[0027] At the same time, when each positioning clamping plate approaches each other, it will squeeze the dislocation cavity, which is easy for the positioning clamping plates to approach each other, convenient for clamping the bearing. At the same time, it can be adjusted by the way that each positioning clamping plate approaches and spreads towards the locking sleeve, and can adapt to bearings of different sizes;

[0028] And when the positioning clamp plate clamps the bearing, the supporting ball holder can abut against the outer side of the bearing, which can not only ensure the stability of the bearing installation but also prevent the positioning clamp plate from contacting the bearing and causing the bearing to be unable to rotate, thus realizing the function of reducing friction.

[0029] Different from the prior art, the present application discloses an adjustable bearing bush. By the threaded connection between the internal thread sleeve and the positioning clamp plate and in cooperation with the conical cross-section of the locking sleeve, when the locking sleeve displaces, it pulls each positioning clamp plate to gather towards the center point of the locking sleeve, and then makes each positioning clamp plate approach each other to clamp the bearing. At the same time, when each positioning clamp plate approaches each other, it will squeeze the dislocation cavity, which is conducive to the mutual approach of the positioning clamp plates and convenient for clamping the bearing. At the same time, by adjusting the way that each positioning clamp plate approaches and spreads towards the locking sleeve, it can adapt to bearings of different sizes. And when the positioning clamp plate clamps the bearing, the supporting ball holder can abut against the outer side of the bearing, which can not only ensure the stability of the bearing installation but also prevent the positioning clamp plate from contacting the bearing and causing the bearing to be unable to rotate, thus realizing the function of reducing friction.

[0030] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
