Problems solved by technology

[0002] At present, the structure of the oil seal is mostly composed of three parts: spring, skeleton and rubber (such as figure 1 As shown), the spring is assembled to the sealing lip of the oil seal, the production process control is more complicated, and after the spring is assembled, the inner diameter of the product is not easy to control, and the size fluctuates greatly, which affects the stability of the sealing performance. Although it can meet the requirements of general sealing The system is used, but there are still some hidden dangers that need to be improved and breakthroughs; there are also some oil seal structures that omit the structure of the spring (such as figure 2 shown), but the sealing performance and function used under the same service conditions, the effect is far inferior to the oil seal with spring structure

Embodiment Construction

[0011] refer to image 3 , an oil seal with a threaded lip structure, consisting of an annular rubber body 2 and a skeleton 1 placed in the rubber body through vulcanization, the outer wall 5 of the oil seal of the annular rubber body 2 is in sealing fit with the inner wall of the cavity 6, so The inner wall of the ring-shaped rubber body 2 is a threaded lip 4 with more than 2 teeth, and the threaded lip and the working shaft 9 are tightly fitted, and the rotation structure of the threaded lip 4 is opposite to the rotating direction of the working shaft 9 .

[0012] The present invention is composed of two main body skeletons 1 and an annular rubber body 2, which is the same structure as the traditional oil seal, but without a spring structure, vulcanized and bonded by a vulcanization mold, and the sealing lip is designed as a threaded structure after molding. The crest radius, pitch and depth of the thread structure are the key structures of this oil seal. The mating surface...

Abstract

The invention discloses a threaded lip structural oil seal. The oil seal consists of an annular rubber body and a framework which is vulcanized in the rubber body, wherein the outer side wall of the annular rubber body is in seal fit with the inner wall of a cavity body, the inner side wall of the annular rubber body is of a threaded lip structure with more than 2 teeth, and a threaded lip is in interference fit with a working shaft. The rotation direction of a rotary structure of the threaded lip is opposite to the rotation direction of the working shaft. A traditional oil seal lip structure is changed into a threaded multi-lip structure, a sealing contact part is added, so that the oil seal has the characteristics of high pressure resistance and high speed resistance, the threaded lip structure can play a function of returning oil, the stability of a whole sealing system is ensured, the oil seal does not have a spring structure and is safe and convenient to product, and the production efficiency is effectively increased.

Description

technical field [0001] The invention relates to a lip structure oil seal, in particular to a threaded lip structure oil seal. Background technique [0002] At present, the structure of the oil seal is mostly composed of three parts: spring, skeleton and rubber (such as figure 1 As shown), the spring is assembled to the sealing lip of the oil seal, the production process control is more complicated, and after the spring is assembled, the inner diameter of the product is not easy to control, and the size fluctuates greatly, which affects the stability of the sealing performance. Although it can meet the requirements of general sealing The system is used, but there are still some hidden dangers that need to be improved and breakthroughs; there are also some oil seal structures that omit the structure of the spring (such as figure 2 Shown), but the sealing performance and effect used under the same service conditions, the effect is far inferior to the oil seal with spring stru...
