Description

Bearing assembly structure capable of preventing shaft and bearing from being abraded

Technical Field

The utility model relates to the technical field of bearing assembly, in particular to a bearing assembly structure capable of preventing a shaft and a bearing from being abraded.

Background

The rolling bearing is a transition carrier for bearing two states of motion and static, aiming at the use occasions that an outer ring of the rolling bearing is fixed and an inner ring of the rolling bearing rotates, the service life of a bearing structure is greatly influenced by the matching mode of the inner ring of the rolling bearing and a rotating shaft, if the inner ring of the rolling bearing and the rotating shaft are loosened, the contact surfaces of the inner ring and the rotating shaft are easily abraded, the whole service life of the rolling bearing is influenced, and noise is generated. In order to avoid abrasion of the rolling bearing and the rotating shaft, the inner ring of the rolling bearing and the rotating shaft need not to be loosened, the current common practice is to fix the inner ring of the rolling bearing and the rotating shaft by glue or to realize assembly of the inner ring of the rolling bearing and the rotating shaft by an interference press-in mode, the glue is adopted to fix the inner ring of the rolling bearing and the rotating shaft, the glue is easy to lose efficacy after high and low temperature impact, thermal expansion and cold contraction or severe vibration, and the interference press-in assembly mode is not suitable for many products due to the limitation of the process and has poor applicability.

Accordingly, the prior art is deficient and needs improvement.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects of the prior art and provide a bearing assembling structure capable of preventing a shaft and a bearing from being worn.

The technical scheme of the utility model is as follows: a bearing assembly structure capable of preventing a shaft from being worn by a bearing comprises the bearing and a rotating shaft; the rotation axis wears to locate the inner circle of bearing and with clearance fit is realized to the inner circle, just the rotation axis is arranged in some in the inner circle has been seted up a plurality of rings of adjustment tank from last to down in proper order, every circle all correspond in the adjustment tank and install an adjusting part, each the adjusting part all with the inner circle is laminated mutually, is used for the inner circle of bearing with provide a tensile force between the rotation axis and take place relative rotation with the rotation axis in order to prevent the inner circle of bearing.

Further, the number of the adjusting grooves is two, and correspondingly, the number of the adjusting pieces is two.

Further, each adjusting piece is a rubber ring.

By adopting the scheme, the utility model has the following beneficial effects:

according to the design of the utility model, the tension force is provided between the inner ring of the bearing and the rotating shaft through the plurality of adjusting parts, the inner ring of the bearing and the rotating shaft are effectively prevented from rotating relatively, the abrasion of the inner ring of the bearing and the rotating shaft is avoided, the service life of the bearing is long, the generation of noise can also be avoided, the structure is simple and ingenious, the bearing can adapt to high and low temperature impact, thermal expansion and cold contraction and vibration scenes, the stability is good, the applicability is strong, the design is exquisite, and the bearing is worthy of great social popularization.

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to the structures shown in the drawings without creative efforts.

FIG. 1 is a schematic structural diagram of the present invention.

The implementation, functional features and advantages of the objects of the present invention will be further explained with reference to the accompanying drawings.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the utility model and are not limiting of the utility model. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.

In the description of the present invention, unless expressly stated or limited otherwise, the terms "connected," "connected," and "fixed" are to be construed broadly, e.g., as meaning permanently connected, removably connected, or integral to one another; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

In the present invention, unless otherwise expressly stated or limited, "above" or "below" a first feature means that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact with each other via another feature therebetween. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.

In the description of the present embodiment, the terms "upper", "lower", "left", "right", and the like are used based on the orientations and positional relationships shown in the drawings only for convenience of description and simplification of operation, and do not indicate or imply that the referred device or element must have a specific orientation, be configured and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
