Embodiment 1

[0023] Such as Figure 1-2 As shown, the outer ring of the tapered roller bearing includes a cylindrical outer ring body 1, and the outer ring body 1 is respectively provided with two mutually symmetrically arranged tapered holes 11, the diameter of the inner end of the tapered hole 11 extends to the outer end The diameter gradually increases, and a cylindrical hole 12 is formed between the two tapered holes 11. The outer ring body 1 is provided with an inward groove and an annular groove 13 located between the two tapered holes 11 in the circumferential outer side. The annular groove 13 is provided with a number of mounting holes 14 that penetrate the outer ring body 1 and are connected to the cylindrical hole 12. In the mounting holes 14, the mounting structure 2 is provided with a fixing pin 3 that runs through the entire mounting hole 14. The fixing pin 3 It is a hollow structure with an inner cavity 31 for storing lubricating oil, and the inner end of the fixed pin 3 is c...

Embodiment 2

[0027] Such as image 3 As shown, the structure, principle and implementation steps of this embodiment are similar to those of Embodiment 1, the difference lies in that the drive assembly in this embodiment includes a drive rod 43 that passes through the fixed pin 3 and is connected to the piston body 41 , the drive rod 43 has an external thread 44 on the outside of the circumference, and the fixed pin 3 has an internal thread 45 matching the external thread 44 on the inside of the circumference, and the drive rod 43 is screwed to the fixed pin 3, that is, by rotating the drive rod 43 in the circumferential direction so that The piston body 41 moves.

Abstract

The invention relates to an outer ring of a tapered roller bearing. The outer ring solves the technical problems that the strength of the outer ring of a conventional tapered roller bearing is low and the like. The outer ring comprises an outer ring body, two tapered holes and a column-shaped hole, wherein annular grooves are formed in the outer side in the circumferential direction of the outer ring body, and a plurality of mounting holes penetrating through the outer ring body and are communicated with the column-shaped hole are formed in the annular grooves; fixing pins penetrating through the whole mounting holes are arranged in the mounting holes through a mounting structure, each fixing pin adopts a hollow structure with an inner cavity for accommodating lubricating oil, the inner ends of the fixing pins are closed and extend to the inner side in the circumferential direction of the outer ring body, the outer ends of the fixing pins are opened, a plurality of liquid outlet holes communicated with the inner cavity are formed in the outer sides in the circumferential directions of the inner ends of the fixing pins, and liquid outlet controlling mechanisms are arranged in the fixing pins. The outer ring has the following advantages of simple structure, good stability and high strength, a lubricating oil adding structure is arranged, so that the lubrication effect of a finished bearing product is good, and wear and tear do not easy to generate.

Description

technical field [0001] The invention belongs to the technical field of auto parts, in particular to an outer ring of a tapered roller bearing. Background technique [0002] Tapered roller bearings are separable bearings, and the inner and outer rings of the bearing have tapered raceways. This type of bearing is divided into different structural types such as single row, double row and four row tapered roller bearings according to the number of rows of rollers installed. Tapered roller bearings are widely used in automobiles, rolling mills and other fields. Because the bearings often work in Under harsh working conditions such as impact, high temperature, high speed, and heavy load, it is easy to deform, and the outer ring of the existing tapered roller bearing has the problems of inconvenient processing and high cost, and for tapered roller bearings with more than double rows As far as the bearing is concerned, it is very easy to cause the bearing sealing effect to deterior...
