Rockwell sealing ring and production method thereof

Abstract

The invention discloses a Rockwell sealing ring comprising a main sealing ring and a secondary sealing ring which are parallel to each other, wherein the main sealing ring is connected with the secondary sealing ring in an embedding mode. A groove is disposed at the outer peripheral surface of the main sealing ring, and an elastic ring is embedded in the groove. A sealing main lip is arranged on the inner peripheral surface of the main sealing ring. The invention also discloses a production method of the Rockwell sealing ring. With the advantages of simple structure and convenient processing, the Rockwell sealing ring can enhance processing efficiency and reduce processing cost.

Description

technical field [0001] The invention relates to the sealing technology of rotating shafts in industrial production, such as sealing products used in bearing housings or reducers, in particular to a Rockwell sealing ring and a preparation method thereof. Background technique [0002] The disadvantage of the commonly used rotary shaft skeleton seal ring at present is that the installation and replacement requires equipment shutdown, and all the installation parts around the skeleton seal ring are removed. The work intensity is high and the efficiency is low, especially the disassembly and installation of large equipment is very troublesome. In some equipment, the installation position of the skeleton sealing ring is small, or it is blocked by other parts, making it difficult to disassemble. [0003] In addition, in order to solve the difficult problem of disassembly and assembly, some sealing rings adopt the method of cutting the sealing ring. However, the single-split cut bri...

AI Technical Summary

Problems solved by technology

[0002] The disadvantage of the commonly used rotary shaft skeleton seal ring at present is that the installation and replacement requires equipment shutdown, and all the installation parts around the skeleton seal ring are removed. The work intensity is high and the efficiency is low, especially the disassembly and installation of large equipment is very troublesome.

In some equipment, the installation position of the skeleton sealing ring is small, or it is blocked by other parts, so it is difficult to disassemble and assemble

[0003] In addition, in order to solve the difficult problem of disassembly and assembly, some sealing rings adopt the method of cutting the sealing ring. However, the single-split cut brings the problem of leakage, and the split opening is easy to dislocate and the overall rigidity is poor. Therefore, the split technology of the sealing ring has become a difficult problem in the sealing industry

[0004] The utility model with the patent number "200620132713.4" discloses a double-ring split bearing protector with a clamping mechanism. Although it solves the problems of difficulty in disassembly and assembly and leakage, if Figure 4 As shown, its complex structure leads to complicated processing and production and high production cost

In addition, if Figure 5 As shown, the cutout of the outer ring is complex, and an insert-type joint is used. The insert-type joint is composed of an insertion part protruding in the circumferential direction and bulging to both sides at one end of the outer ring and an insertion part at the other end of the outer ring. Matching groove-shaped accommodating part constitutes, in fact, this complex incision shape is unnecessary, which will lead to complex processing and low processing production efficiency
