Embodiment Construction

[0032] Specific embodiments of the present invention are described in further detail below:

[0033] The ceramic powder dispersion-enhanced floating oil seal designed in the present invention includes a pair of sealing rings with symmetrical upper and lower structures. The sealing rings are mainly made of metal materials, and the metal materials are doped with ceramic materials. , the added amount of the ceramic material does not exceed 5% of the total mass of the metal material, and the ceramic material is in the form of a powder and is distributed in the metal material in the form of a dispersed phase.

[0034] The amount of the ceramic material added is preferably 0.05% to 1.2% of the total mass of the metal material, most preferably 0.6% to 0.8% of the total mass of the metal material.

[0035] The particle size of the ceramic material is preferably no more than 60nm, preferably 10-30nm.

[0036] The ceramic material is preferably A1 2 o 3 , ThO 2 , Y 2 o 3 Ceramic p...

Abstract

The invention provides a ceramic powder dispersion-reinforced floating oil seal. The floating oil seal comprises a pair of seal rings with upper and lower symmetrical structures. The seal ring is prepared mainly from a metal material. The metal material contains a ceramic material. A use amount of the ceramic material is less than or equal to 5% total mass of the metal material. The ceramic material is powder and is distributed in the metal material in a dispersed phase form. The invention also provides a method for preparing a floating oil seal blank through a forging method. The method effectively improves a work surface wear-resistant degree, increases a service life, has simple processes and has a low production cost.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a ceramic powder dispersion-enhanced floating oil seal used for floating end face seals in mechanical equipment and a method for preparing a forged blank thereof. 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 wide application (the national annual demand exceeds ten million pieces). This seal is composed of two metal floating end face seal rings (referred to as floating oil seal) and "O" type rubber sealing ring is installed on the central shaft. It 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 the sealing structure. Due to the special environment in which the floating oil seal is used, it is a vulnerable part. The exposed installation locatio...
