Problems solved by technology

However, in the actual use of industrial sites, there are many structural forms of this kind of skeleton seal ring. On the one hand, there are missing and missing spare parts, and secondly, the pace of large industrial production sites is tight. Once the skeleton oil seal leaks, there is usually not enough time to replace it. , leading to the passiveness of mass production and the increase of fuel consumption and the pollution of the on-site environment

Embodiment Construction

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] see figure 1 — Figure 4 , the shaft seal structure claimed in the present invention includes a casing 10, a rotating shaft 20 that is arranged in the casing 10 and protrudes outward relative to the casing 10, wherein the rotating shaft 20 and the casing 10 are sealed with a skeleton The ring 30 is sealed.

[0020] The skeleton sealing ring 30 is provided with a dust-proof ring 31 , and the dust-proof ring 31 is attached to the rotating shaft 20 to form an oil seal. That is to say, the skeleton sealing ring 30 of this embodiment has a dustproof ring 31 , and an oil seal is formed between the dustproof ring 31 and the rotating shaft 20 to achieve sealing.

[0021] It can be understood that the rotating shaft 20 rotates at a high speed relative to the dustproof ring 31 during operation, and the dustproof ring 31 is attached to...

Abstract

The invention discloses a shaft seal structure which comprises a case and a rotary shaft arranged in the case and partially outwards stretching out relative to the case. The rotary shaft and the caseare sealed through a framework sealing ring. The shaft seal structure is characterized in that a dedusting ring is arranged on the framework sealing ring and attached to the rotary shaft to form an oil seal; an O-shaped sealing ring and an arc-shaped conical surface sleeve are sequentially arranged on the position, stretching out of the dedusting ring of the framework sealing ring, of the rotary shaft, the O-shaped sealing ring and the rotary shaft are in interference fit, the arc-shaped conical surface sleeve and the rotary shaft are in clearance fit, and limiting fixing is conducted througha plurality of bolts; and the end face of the side, facing the O-shaped sealing ring, of the arc-shaped conical surface sleeve is arranged to be an arc-shaped face, and the outer circle face of the O-shaped sealing ring is in abutting-fit with the dedusting ring and the arc-shaped face of the arc-shaped conical surface sleeve. According to the shaft seal structure, the sealing effect is good, andself-adjusting recovering sealing for the framework sealing ring with the dedusting ring is achieved.

Description

technical field [0001] The invention belongs to the technical field of sealing structures, and in particular relates to a shaft sealing structure. Background technique [0002] It can be understood that the skeleton sealing ring with dust-proof ring is widely used in industrial sites and has achieved good dynamic sealing effect. However, the skeleton sealing ring with a dust-proof ring is a consumable sealing material. During use or improper use, the oil seal lip is prone to wear and failure, or the sealing lip is torn, and the self-tightening spring falls off, resulting in oil product leakage. [0003] At present, in the prior art, the skeleton sealing ring with a dust-proof ring is directly replaced for maintenance after the above-mentioned phenomenon occurs. However, in the actual use of industrial sites, there are many structural forms of this kind of skeleton seal ring. On the one hand, there are missing and missing spare parts, and secondly, the pace of large industr...
