Problems solved by technology

In actual use, since the oil seal will inevitably be tilted and deflected during installation, the lip 24 of the oil seal lip will be eccentric to the shaft, causing the contact sealing surface to be unable to effectively hold the shaft tightly and the holding force will be wea...

Embodiment Construction

[0030] The sealing ring assembly for a rotary sealing lip type rotating shaft of the present invention includes a rotating sealing lip assembly 1 and a sealing ring skeleton assembly 2 . In the present invention Figure 2 to Figure 5 It is an example of different structures of the sealing ring skeleton assembly 2, Figure 7 to Figure 10 It is an example of different structures of the rotary sealing lip assembly 1 in the present invention. The structural composition of each component and different examples will be described in detail below.

[0031] see figure 2 As shown, the sealing ring frame assembly 2 has an outer diameter portion 12 , a front side 13 , a rear side 14 and an inner wall 18 , and the rear side 14 has a flange 25 bent upward. A concave structure with an opening 31 is formed between the outer diameter portion 12 , the front side 13 and the rear side 14 .

[0032] figure 2 , image 3 and Figure 4 It is a split-type sealing ring skeleton assembly, which...

Abstract

The invention provides a rotary seal lip type seal ring assembly for a rotating shaft. The rotary seal lip type seal ring assembly for the rotating shaft comprises a seal ring framework assembly and a rotating shaft seal lip assembly. The rotating shaft seal lip assembly comprises a steel-iron framework and a sealing lip, the inner side of the steel-iron framework is tightly matched with the rotating shaft and rotates along with the rotating shaft, and the sealing lip is fixedly arranged on the other side of the steel-iron framework and matched with the inner side wall of the seal ring framework assembly. The design differs from the prior art, the steel-iron framework is arranged tightly attached to the rotating shaft side, the sealing lip is arranged on the other side of the steel-iron framework, and thus the problem of oil leakage on-site generation caused by enclasping force weakening brought when the sealing lip rotates along with the rotating shaft can be effectively prevented, an effective seal effect can be kept for a long time, occurrence of an oil leakage phenomenon is avoided, the oil leakage phenomenon is greatly reduced or eliminated, energy resources are saved, cost performance is high, and a hope for thoroughly solving dynamic seal oil leakage is brought.

Description

technical field [0001] The invention relates to a sealing device, in particular to a new type of sealing structure capable of providing a rotary dynamic seal of a rotary sealing lip, and is a new rotary sealing lip type rotary shaft sealing ring assembly with excellent dynamic sealing effect. Background technique [0002] Before the present invention, the sealing ring assembly in the prior art, commonly known as the oil seal, was a static seal of the sealing lip, that is, when the rotating shaft rotated, the sealing lip was tightly attached to the rotating shaft, and the sealing was performed by the sealing lip holding the shaft radially. Sealing, if the radial holding force of the sealing lip on the shaft changes and the oil medium is weakened, it will rotate along the shaft surface of the rotating shaft and leak out. [0003] see Figure 14 and Figure 15 As shown, the oil sealing lip 26 (seal lip) and the dust-proof lip 6 are closely attached to the rotating shaft 7, and...
