Abstract
The utility model relates to a steel ball self-lubricating bearing, which comprises a bearing inner ring, a bearing outer ring and a steel ball arranged between the bearing inner ring and the bearing outer ring, wherein a sealing retainer ring is arranged between the bearing inner ring and the bearing outer ring, the sealing retainer ring comprises a sealing retainer ring main body and a sealing retainer ring fixing part connected with the sealing retainer ring main body, a liquid storage cavity is arranged in the middle of the steel ball, a liquid outlet hole communicated with the liquid storage cavity is formed in the steel ball, and lubricating oil is stored in the liquid storage cavity; when the steel ball rotates at a high speed, lubricating oil stored in the liquid storage cavity is guided out from the liquid outlet hole and enters the bearing, the steel ball is lubricated and cooled, the bearing has the lubricating and cooling functions by the aid of the structural design, and the problem that the traditional bearing is inconvenient to lubricate outside is solved.
Description
Technical Field
The utility model relates to the field of bearing structures, in particular to a steel ball self-lubricating bearing.
Background
The bearing is an important part in the modern mechanical equipment. Its main function is to support the mechanical rotator, reduce the friction coefficient in its motion process and ensure its rotation precision. The structure of bearing mainly includes bearing inner race, the retaining ring in steel ball and the steel ball outside, and the bearing is at the in-process that uses, needs regularly lubricate it, because retaining ring's existence, the in-process of actual lubrication, outside lubricating oil is difficult to contact with inside steel ball, and actual lubricated effect is not good, and this patent is based on current technical problem, improves the structure of bearing.
Disclosure of Invention
The utility model aims to overcome the defects in the prior art and provides a steel ball self-lubricating bearing.
In order to achieve the purpose, the technical scheme adopted by the utility model is as follows:
the utility model provides a steel ball self-lubricating's bearing, includes bearing inner race, bearing inner race and installs the steel ball between bearing inner race, be equipped with the sealing ring between bearing inner race, the sealing ring includes the sealing ring main part and the sealing ring fixed part of being connected with the sealing ring main part, the middle part of steel ball is equipped with the stock solution chamber, is equipped with the play liquid hole with the stock solution chamber intercommunication on the steel ball, stores lubricating oil in the stock solution chamber.
Furthermore, the diameter of the liquid outlet hole is 0.3-2 mm.
Further, the cross-section of the liquid storage cavity is circular.
Further, be equipped with the mounting groove on the medial surface of bearing inner race, in the sealing ring fixed part stretched into the mounting groove, be equipped with annular clamping ring in the mounting groove, annular clamping ring compresses tightly fixed sealing ring fixed part.
Further, the gasket main body and the gasket fixing portion are integrally formed.
The utility model has the beneficial effects that: the middle part of the steel ball of this bearing is equipped with the stock solution chamber, is equipped with the play liquid hole with stock solution chamber intercommunication on the steel ball, and the storage lubricating oil in the stock solution chamber, when the steel ball rotated at a high speed, inside the lubricating oil of storage in the stock solution chamber was derived out and entered into the bearing from going out the liquid hole, lubricated and the cooling to the steel ball, this structural design made bearing itself possess lubricated, the cooling function, had overcome the inconvenient problem of traditional bearing external lubrication.
Drawings
FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
As shown in figure 1, a steel ball self-lubricating bearing comprises a bearing inner ring 1, a bearing outer ring 2 and a steel ball 3 arranged between the bearing inner ring 1 and the bearing outer ring 2, wherein a sealing check ring is arranged between the bearing inner ring 1 and the bearing outer ring 2, the sealing check ring comprises a sealing check ring main body 4 and a sealing check ring fixing part 5 connected with the sealing check ring main body 4, a liquid storage cavity 6 is arranged in the middle of the steel ball 3, a liquid outlet hole 7 communicated with the liquid storage cavity 6 is formed in the steel ball 3, and lubricating oil is stored in the liquid storage cavity 6.
Furthermore, the diameter of the liquid outlet 7 is 0.3-2mm, and the section of the liquid storage cavity 6 is circular. Be equipped with mounting groove 8 on bearing inner race 2's the medial surface, sealing ring fixed part 5 is equipped with annular clamping ring 9 in stretching into mounting groove 8 in the mounting groove 8, and annular clamping ring 9 compresses tightly fixed sealing ring fixed part 5. The gasket body 4 is integrally formed with the gasket fixing portion 5.
The middle part of the steel ball 3 of this bearing is equipped with stock solution chamber 6, is equipped with the play liquid hole 7 with 6 intercommunications in stock solution chamber on the steel ball 3, stores lubricating oil in the stock solution chamber 6, and when 3 high-speed rotations of steel ball, inside lubricating oil that stores in the stock solution chamber 6 was derived out and entered into the bearing from going out the liquid hole, lubricated and the cooling to steel ball 3, this structural design makes bearing itself possess lubricated, the cooling function, has overcome the inconvenient problem of traditional bearing external lubrication.
The foregoing shows and describes the general principles, essential features, and advantages of the utility model. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the utility model, but that various changes and modifications may be made without departing from the spirit and scope of the utility model, which fall within the scope of the utility model as claimed. The scope of the utility model is defined by the appended claims and equivalents thereof.
