Embodiment Construction

[0020] Below in conjunction with accompanying drawing, specific embodiment of the present invention is described in further detail:

[0021] Such as figure 1 As shown, the floating oil seal with oil storage microporous wear-resistant surface designed by the present invention includes a pair of sealing ring bodies 1 with symmetrical upper and lower structures, and friction assemblies are respectively arranged on the two opposite end faces of the sealing ring body 1, The two friction assemblies form a pair of friction pairs 2 that match in position.

[0022] Such as figure 2 As shown, the friction surfaces of one or both of the friction components of the friction pair 2 of the present invention have undergone micro-pit or micro-groove texture treatment, and the surface has widely distributed micro-depressions 3, and the micro-depressions 3 are Micro-pits or micro-grooves are used to store lubricating oil, grease and other lubricating substances, so that an oil film can be for...

Abstract

The invention provides a floating oil seal with oil storage micropore abrasion-resistant faces. The floating oil seal comprises a pair of sealing ring bodies. The structures of the sealing ring bodies are vertically symmetrical. Friction-resistant assemblies are arranged on the two opposite end faces of the pair of sealing ring bodies respectively. The two friction-resistant assemblies form a friction pair which is oppositely matched. The friction-resistant working faces of one or two of the friction-resistant assemblies of the friction pair are of a micro-pit or micro-groove textured structure. Micro-concave-parts which are widely distributed are formed in the surfaces of the friction-resistant working faces, are micro-pits or micro-grooves and are sued for storing lubricating oil, lubricating grease and other lubricating substances, and oil films can be formed on the surfaces of the friction-resistant working faces respectively. By means of the floating oil seal, the friction resistance of the working faces can be effectively improved, the service life is prolonged, and sealing can be effectively ensured.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a floating oil seal with oil storage microporous wear-resistant surface used for sealing floating end faces in mechanical equipment. Background technique [0002] The floating oil seal is applied to the floating end face seal. It is a mechanical seal with a large amount of use and a wide range of applications (nearly 100 million pieces are needed annually in the country). The "O" type rubber sealing ring is assembled in the special sealing cavity - the floating seal seat. Its metal sealing surface has the characteristics of wear resistance, impact resistance, certain adaptability, long life, simple structure, low price, and convenient maintenance and replacement. It is widely used in mining, construction machinery, construction machinery, agricultural machinery, transportation machinery, deep well drilling rig , It is widely used in the sealing structure of underground mining machinery....
