Description

Rolling bearing

Technical Field

The utility model relates to a antifriction bearing especially relates to a antifriction bearing convenient to just be convenient for quick assembly disassembly through screw thread and hub connection.

Background

A rolling bearing is a precise mechanical element that reduces friction loss by changing sliding friction between a running shaft and a shaft seat into rolling friction. The rolling bearing generally comprises four parts, namely an inner ring, an outer ring, a rolling body and a retainer, wherein the inner ring is used for being matched with a shaft and rotating together with the shaft; the outer ring is matched with the bearing seat to play a supporting role; the rolling bodies are uniformly distributed between the inner ring and the outer ring by virtue of the retainer, and the shape, size and number of the rolling bodies directly influence the service performance and service life of the rolling bearing; the retainer can enable the rolling bodies to be uniformly distributed and guide the rolling bodies to rotate to play a lubricating role.

The terminal surface of traditional antifriction bearing is the plane, and the inner wall of its inner circle is smooth, and direct interference connection between with the axle, and the biggest problem of this kind of structure is that the dismouting is inconvenient, wastes time and energy, and in the limited occasion of operating space especially, the dismouting especially dismantles very troublesome, leads to the reuse difficulty of bearing, has improved the product acquisition cost.

In order to solve the above problems, the inner ring and the shaft are connected by screw threads, for example, the utility model patent with the patent number "Z L00264340.5" discloses a novel rolling bearing, one end of the inner ring is longer, the outer surface of the longer part of the inner ring is provided with mutually parallel planes for loading and unloading the bearing by a wrench, the inner surface of the inner ring is provided with screw threads, the outer ring is provided with a circular ring for limiting the depth of the bearing to be loaded into a workpiece on the outer surface of the same longer end of the inner ring, and the problem of convenient assembly and disassembly can be solved by screw thread connection and disassembly by a wrench.

However, the above patent presents a new problem of directly providing a flat surface on an extension of one end of the inner ring for engagement with the wrench, and this structure has a length of the flat surface that can be engaged with the wrench only when the thickness of the inner ring is large enough and does not slip. However, in general, the thickness of the inner ring cannot be too large, because the too thick inner ring not only increases the rotation load but also wastes material cost except for matching with a wrench, more importantly, the structure can only change the structure of the inner ring during production, and cannot modify the finished product which is processed, and because the thickness of the inner ring cannot be increased by a modification mode, the application effect is reduced, and the application range is narrowed.

SUMMERY OF THE UTILITY MODEL

The utility model provides a need not increase inner circle thickness, can cooperate and be convenient for carry out the antifriction bearing that reequips to the finished product that has processed well with the spanner well, solve the inner circle too thick be unfavorable for rotatory and reduce cost, can not carry out the problem of reequiping to the finished product that has processed.

In order to achieve the above object, the utility model adopts the following technical scheme:

the rolling bearing comprises an inner ring, an outer ring, a rolling body and a retainer, wherein the rolling body and the retainer are arranged between the inner ring and the outer ring, an internal thread is arranged on the hole wall of an inner ring through hole of the inner ring, one end of the inner ring is connected with six linear strip-shaped blocks with rectangular or square radial sections, the six strip-shaped blocks are uniformly distributed on the annular surface of one end of the inner ring, the six strip-shaped blocks are arranged on the inner side of the circular center, the inner side surface of each strip-shaped block is flush with the inner side edge of the inner ring or is closer to the outer side of the inner ring.

Preferably, the length of the strip-shaped blocks can be longer or shorter as required, for example, a gap is reserved between two adjacent strip-shaped blocks and the two adjacent strip-shaped blocks are close to each other as much as possible, the strip-shaped blocks are welded with the inner ring, the strip-shaped blocks of the structure are longer in length and more convenient to be matched with a wrench for use, but the parts of the two ends of the strip-shaped blocks, which are arranged between the inner ring and the outer ring, are longer, so that the installation of the retainer is influenced, and the welding is required after the retainer is installed; or the length of the strip-shaped blocks meets the following requirements: the two ends of the strip-shaped block are arranged in the inner ring and the part between the outer rings does not influence the installation of the retainer, the strip-shaped block and the inner ring are integrally formed or welded, the length of the strip-shaped block is short, the length of the strip-shaped block does not influence the installation of the retainer and the installation of the rolling body on the premise of ensuring the matching use with a wrench, and therefore the strip-shaped block and the inner ring can be integrally formed when the inner ring is machined to increase the strength.

Preferably, in order to completely avoid the normal use of the strip-shaped blocks for the retainer and other accessories, one end of the inner ring connected with the strip-shaped blocks extends out of the end face of the corresponding end of the outer ring by 1-10 mm. This makes it possible to provide a sufficient space for mounting fittings such as retainers at both ends of the rolling bearing.

Compared with the prior art, the utility model discloses following beneficial effect has:

the utility model discloses a connect six bar pieces that evenly distribute in the circumference at the inner circle one end of antifriction bearing, the surface of the outside of six bar pieces and extension face constitute the regular hexagon surface in the outside jointly, the surface of the inside of six bar pieces and extension face constitute the regular hexagon surface in the inboard jointly, can fully cooperate with interior hexagonal spanner, outer hexagonal spanner and ordinary open-ended spanner respectively and use; meanwhile, the thickness of the strip-shaped block does not influence the use effect, and the thickening treatment of the inner ring is not needed, so that a processed finished product can be modified, and the use range is enlarged.
