Description

Anti-centrifugal mechanical bearing

Technical Field

The utility model relates to the technical field of bearings, in particular to an anti-centrifugal mechanical bearing.

Background

Bearings (Bearing) are components that act to fix and reduce the coefficient of friction of the load during mechanical transmission. It can also be said that the member for reducing the friction coefficient during power transmission and keeping the center position of the shaft fixed when the other members are moved relative to each other on the shaft. The bearing is a lightweight part in modern mechanical equipment. Its main function is to support the mechanical rotating body to reduce the friction coefficient of mechanical load of equipment in the transmission process. The bearings can be classified into rolling bearings and sliding bearings according to the frictional properties of the moving elements.

In order to reduce the abrasion of the rolling body in the bearing, lubricating oil is usually arranged in the bearing, but because the outer ring and the inner ring of the bearing can continuously rotate when the bearing works, the lubricating oil can be intensively distributed on one side close to the outer ring of the bearing under the action of centrifugal force, so that the abrasion of the bearing is rapidly increased, the service life is shortened, and how to solve the problems has positive significance for promoting the technical development in the field.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide an anti-centrifugal mechanical bearing to solve the problems in the background art.

The bearing outer ring and the bearing inner ring are arranged between the bearing outer ring and the bearing inner ring to form a rolling pair, the side surfaces of the bearing outer ring and the bearing inner ring are provided with sealing layers for sealing the bearing outer ring and the bearing inner ring, a lubricating oil layer is filled in a space formed by the bearing outer ring, the bearing inner ring and the sealing layers, the opening is arranged on the inner side of the bearing outer ring, the sliding block is arranged in the opening to form a moving pair, the sliding block and the rolling body are mutually attracted, and one end of the connecting spring is connected with the bearing outer ring while the other end is connected with the sliding block.

Preferably, the rolling elements are spherical.

Preferably, the opening is formed in the inner side of the bearing outer ring and is not in contact with the rolling body.

Preferably, the openings are arranged in two rows and separately arranged on the inner side of the bearing outer ring and are not in contact with the rolling bodies.

Preferably, the sliding block is strip-shaped and points to the circle center of the bearing outer ring.

From the above description of the structure of the present invention, compared with the prior art, the present invention has the following advantages:

the utility model provides an anti-centrifugal mechanical bearing, wherein a bearing outer ring and a bearing inner ring can rotate relatively when the bearing works, a lubricating oil layer can be intensively distributed at one side close to the bearing outer ring under the action of centrifugal force, and because a sliding block and a rolling body are mutually attracted, when the rolling body rolls to be close to a hole, the sliding block in the hole can slide out along the hole, so that the disorder of the lubricating oil layer is increased, the lubricating oil layer cannot be intensively distributed at one side close to the bearing outer ring, and then when the hole is formed according to the principle of the rolling body, the sliding block returns to the hole under the elastic action of a connecting spring.

The utility model utilizes the continuous rotation of the bearing inner ring and the bearing outer ring when the bearing works to lead the sliding block to extend and retract to open the hole in a reciprocating way, can improve the disorder of the lubricating oil and avoid the phenomenon that the abrasion of the bearing is increased sharply to cause the shortening of the service life because the lubricating oil is intensively distributed at one side close to the bearing outer ring, has practical significance and popularization value, and can generate good economic benefit in expectation.

FIG. 1 is a schematic cross-sectional configuration of the present invention;

FIG. 2 is a schematic view of the structure of the portion A in FIG. 1;

in the figure: the bearing comprises a bearing outer ring 1, a sealing layer 11, a bearing inner ring 2, a rolling body 3, an opening 4, a sliding block 5 and a connecting spring 6.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Examples

With reference to fig. 1-2, an anti-centrifugal mechanical bearing includes a bearing outer ring 1, a bearing inner ring 2, rolling elements 3, openings 4, a slider 5 and a connecting spring 6, wherein the rolling elements 3 are disposed between the bearing outer ring 1 and the bearing inner ring 2 to form a rolling pair, sealing layers 11 for sealing the bearing outer ring 1 and the bearing inner ring 2 are disposed on the side surfaces of the bearing outer ring 1 and the bearing inner ring 2, a lubricating oil layer is filled in a space formed by the bearing outer ring 1, the bearing inner ring 2 and the sealing layers 11, the openings 4 are disposed in two rows and separately disposed on the inner side of the bearing outer ring 1 and have no contact with the rolling elements 3, the slider 5 is disposed in the openings 4 to form a sliding pair, the slider 5 and the rolling elements 3 are attracted to each other, the slider 5 is in a strip shape and points to the center of the bearing outer ring 1, and one end of the connecting spring 6 is connected with the bearing outer ring 1 and the other end is connected with the slider 5.

The rolling elements 3 are particles capable of rolling, and convert sliding friction into rolling friction, and in a specific embodiment, the rolling elements are spherical.

The slider 5 is a slidable block member, and is made of a material having magnetic properties capable of attracting the rolling elements.

The working principle of the utility model is as follows: bearing during operation bearing inner race 1 and bearing inner race 2 will produce relative rotation, lubricated oil reservoir will concentrate under the effect of centrifugal force to distribute in being close to bearing inner race 1 one side, because slider 5 and rolling element 3 inter attraction, consequently when rolling element 3 rolls and is close to trompil 4, slider 5 in the trompil 4 will follow the unordered increase that trompil 4 roll-off made lubricated oil reservoir make it can't concentrate to distribute in being close to bearing inner race 1 one side, later when 3 principle trompils of rolling element, in the trompil is returned again to slider 5 under coupling spring 6's elastic action in the trompil.
