Description

Caster wheel sleeve

Technical Field

The utility model relates to the technical field of sleeves, in particular to a caster sleeve.

Background

The caster is a common product, and is usually installed at the bottom of furniture, a cart or a lathe, so that the furniture can be flexibly and conveniently moved. The roller part of the caster is generally provided with important parts such as a bearing, a sleeve, a rotating shaft and the like, and the rotating shaft can be protected by the sleeve; since the rotating shaft and the sleeve are in continuous friction rotation in the process of matching use, sufficient lubrication needs to be ensured between the sleeve and the rotating shaft.

In the prior art, lubricating oil is added between a sleeve and a rotating shaft generally. Because need add lubricating oil on the internal contact surface between pivot and the sleeve pipe, need to add to inside again after separating pivot and sleeve pipe when adding, whole process procedure is loaded down with trivial details, brings very big inconvenience for the user.

SUMMERY OF THE UTILITY MODEL

The present invention is directed to a caster bushing, which solves one or more of the problems of the related art.

In order to achieve the purpose, the utility model adopts the following scheme: the caster casing comprises a cylindrical casing body, wherein outer grooves are symmetrically arranged on the outer wall surface of the casing body at intervals, inner grooves are symmetrically arranged on the inner wall surface of the casing body at intervals, an oil groove is formed in the outer wall surface of the casing body along the axis direction of the casing body, one end of the oil groove extends to the end face of the casing body, the other end of the oil groove is communicated with the outer grooves, and through holes communicated with the inner grooves are formed in the oil groove.

According to the caster bushing, the outer grooves and the inner grooves are arranged in a staggered mode at intervals.

According to the caster bushing, two oil grooves are symmetrically arranged at intervals.

According to the caster casing, the outer end corners of the outer groove and the inner groove are chamfered to form an oblique angle structure or a round angle structure.

According to the caster bushing, the inner walls of the two ends of the bushing body are provided with the annular grooves, and the annular grooves are internally provided with the gasket rings.

The caster bushing as described above, the inner bore diameter of the gasket ring is smaller than the inner bore diameter of the bushing body by a difference of 1mm to 2 mm.

The caster bushing is characterized in that the outer edge of the inner hole of the gasket ring is chamfered to form an oblique angle structure or a round angle structure.

In conclusion, the beneficial effects of the utility model are as follows: lubricating oil is injected from the oil groove, then through the arrangement of the outer groove, the inner groove and the through hole, the lubricating oil can be used for self-lubricating the whole sleeve body, the convenience of adding the lubricating oil is improved, and the service life of the sleeve can be greatly prolonged.

Detailed Description

The following detailed description provides many different embodiments or examples for implementing the utility model. Of course, these are merely embodiments or examples and are not intended to be limiting. In addition, repeated reference numbers, such as repeated numbers and/or letters, may be used in various embodiments. These iterations are for simplicity and clarity of describing the present invention and are not intended to represent a particular relationship between the various embodiments and/or configurations discussed.

The utility model is further described in the following description of the drawings and the detailed description: as shown in fig. 1 to 3, the caster casing comprises a cylindrical casing body 1, wherein outer grooves 2 are symmetrically arranged on the outer wall surface of the casing body 1 at intervals, inner grooves 3 are symmetrically arranged on the inner wall surface of the casing body 1 at intervals, an oil groove 4 is arranged on the outer wall surface of the casing body 1 along the axis direction of the casing body 1, one end of the oil groove 4 extends to the end surface of the casing body 1, the other end of the oil groove is communicated with the outer grooves 2, and a through hole 5 communicated with the inner grooves 3 is arranged on the oil groove 4; lubricating oil is injected from the oil groove 4, and then through the setting of outer groove 2, inner groove 3 and through-hole 5, lubricating oil can be made to carry out the self-lubricating to whole sleeve pipe body 1, the convenience of additional lubrication oil has been improved to can improve sheathed tube life greatly.

Further, outer slot 2 staggers the setting with interior slot 3 interval, avoids outer slot 2 and interior slot 3 on same position to can not cause the wall thickness of position department between outer slot 2 and the interior slot 3 to be thinner, can ensure sleeve pipe body 1's intensity.

Preferably, the oil grooves 4 are symmetrically arranged at intervals, so that the sleeve body 1 can be more uniformly filled with lubricating oil for lubrication.

Furthermore, the outer end corners of the outer groove 2 and the inner groove 3 are respectively provided with an oblique angle structure or a fillet structure, so that lubricating oil in the outer groove 2 and the inner groove 3 can flow out for lubrication.

In this embodiment, be equipped with annular 51 on the inner wall at the both ends of sleeve pipe body 1 liner ring 52 is equipped with in the annular 51, liner ring 52's hole diameter is less than sleeve pipe body 1's hole diameter, and the difference is 1mm-2mm to through liner ring 52's setting, can alleviate the friction between pivot and the 1 inner wall of sleeve pipe body, and can be in a bit gap between sleeve pipe body 1 inner wall and the pivot, be convenient for lubricating oil lubricates both.

Further, the outer edge of the inner hole of the gasket ring 52 is chamfered with an oblique angle structure or a round angle structure, so that the installation of the rotating shaft can be facilitated.

While the principles and features of this invention and its advantages have been shown and described in detail in the drawings and foregoing description, it will be understood by those skilled in the art that the utility model is not limited to the details of the embodiments illustrated, and that various changes and modifications may be made therein without departing from the spirit and scope of the utility model. The scope of the utility model is defined by the appended claims and equivalents thereof.
