Wear-resistance oil slinger for high-speed wire rod mill

Abstract

The invention discloses a wear-resistance oil slinger for a high-speed wire rod mill. The wear-resistance oil slinger consists of an inner oil slinger and an outer oil slinger, wherein the outlines of the cross sections of the inner oil slinger and the outer oil slinger are respectively in an L shape, sealing grooves are formed in the bottom surfaces of the inner oil slinger and the outer oil slinger, the outline of the cross section is in a U shape after the inner oil slinger and the outer oil slinger are in split joint, and the inner walls of the inner oil slinger and the outer oil slinger are provided with wear-resistance coatings. The wear-resistance oil slinger has the advantages that the supersonic speed molybdenum spraying coatings are adopted at the inner walls of the inner oil slinger and the outer oil slinger, the wear-reducing performance of the product is greatly improved, the friction factor of the double-lip sealing of the rubber and the inner wall of the oil slinger is reduced to the minimum, the service life of the double-lip sealing is greatly prolonged, the product is subjected to high-temperature-resistance oil resin hole sealing treatment after the molybdenum spraying, the self lubricating performance of the product and the pasting performance of the product with the rubber are improved, water is prevented from entering a roller shaft, and oil is prevented from being leaked from an oil film bearing.

Description

technical field [0001] The invention relates to a wear-resistant oil flinger for a high-speed wire rolling mill. Background technique [0002] The roll box of high-speed wire rod mill is the core unit of high-speed wire rod production, which is very important to the quality and output of high-speed wire rod. The roller shaft and the roll box are sealed with a double-lip seal. This structure is composed of an inner oil throwing ring, a double-lip seal and an outer oil throwing ring. When in use, the inner and outer oil throwing rings rotate together with the roll shaft, and the double lip seal is integrated with the roll box. , relative to the roll shaft, the inner and outer oil throwing rings are stationary, and the speed of the roll shaft can reach 11,000 rpm when rotating at high speed. The inner surface of the inner and outer oil throwing rings rubs against the rubber double lip seal violently. When the grinding performance is not good, the double-lip seal will be damage...

Problems solved by technology

The roller shaft and the roll box are sealed with a double-lip seal. This structure is composed of an inner oil throwing ring, a double-lip seal and an outer oil throwing ring. When in use, the inner and outer oil throwing rings rotate together with the roll shaft, and the double lip seal is integrated with the roll box. , relative to the roll shaft, the inner and outer oil throwing rings are stationary, and the speed of the roll shaft can reach 11,000 rpm when the roll shaft rotates at high speed. When the grinding performance is not good, the double lip seal will be damaged, causing water leakage in the roll box, affecting the oil circuit system of the high-speed wire rod finishing mill, and in severe cases, shaft burning will occur
