Problems solved by technology

If the two iron rings are not tightly fitted, the fitting surface is loosened, and the gap expands, oil seepage occurs and the oil leaks, causing the seal to fail and must be stopped for replacement.

Abstract

The invention provides an iron-plastic combined super-wear-resistant high-strength floating oil seal ring and a manufacturing method thereof. The iron-plastic combined super-wear-resistant high-strength floating oil seal ring is characterized in that an iron sheet ring is arranged on the working surface of a plastic ring body, the iron sheet ring comprises an annular groove with a U-shaped cross section, a wear-resistant material layer is filled in the annular groove, an opened groove allowing an O-shaped rubber ring to be placed is formed in the plastic ring body, the working surface of the plastic ring body is provided with an iron sheet ring mounting groove for allowing the iron sheet ring to be mounted, the inner side wall of the iron sheet ring mounting groove is provided with clamping pin inserting grooves which allow fixing clamping pins to be conveniently inserted thereinto, the lower edges of the iron sheet ring mounting grooves are provided with clamping jaw mounting grooveswhich allow fixing clamping jaws to be conveniently installed, and the tops of the clamping jaw mounting grooves are provided with flanging edge insertion grooves which allow flanging edges to be conveniently inserted thereinto. Due to the fact that wear-resistant materials which are filled into the U-shaped annular groove are few, the effects of being more economical and optimized are achieved, the material are sufficient for use, and are not excess, and waste is avoided; and the high-strength super-wear-resistant floating oil seal ring is ingeniously combined through a mode of using plasticto replace steel.

Description

technical field [0001] The invention relates to the field of machinery, in particular to an iron-plastic composite super wear-resistant high-strength floating oil seal ring and a manufacturing method thereof. Background technique [0002] The core quality of the metal ring of the floating oil seal lies in the sealing performance of the bright band on the working surface, which is reflected in the length of the wear-resistant working life. According to the size of the iron ring, the width of the bright band on the working surface is 3-5mm, which is a limited point. If the bright band is too wide, the adhesive force of the bonding surface of the two rings will be too large, and the tightness will be too tight, and the lubricating oil will not seep in, which will easily cause the two iron rings to lock and cause the apron to slip and rotate. ; At the same time, after the wear amount of the bright belt on the working surface of an iron ring of the floating oil seal reaches 2mm,...
