Special use of medium retaining rings

date:[2015-02-26]     pk_hits:

A medium-sized retaining ring is a separable ring inside a roller bearing with two or more rows of rollers, used to isolate and guide the two rows of rollers. The high hardness particles of the medium-sized retaining ring are distributed on a softer matrix, and together with the solid lubricant in the matrix and the lubricating oil in the pores, they form a special antifriction wear-resistant material, which increases its wear-resistant life by more than 9 times. Generally, the outer diameter is less than 200mm and the wall thickness is more than 2mm. The medium-sized retaining ring and spiral retaining ring have similarities in production, processing, and usage characteristics. They are both made of steel wire flattened and wound, and have undergone heat treatment and surface treatment, exhibiting good elasticity and toughness. The medium-sized retaining ring is divided into two types: shaft and hole, and there are various forms of tail ends to choose from. Powder Metallurgy Medium Retaining Ring: The series produced using powder metallurgy technology has replaced the steel medium retaining ring. The material structure of the medium-sized retaining ring is: pearlite+graphite+cementite+pores.

The characteristics of medium-sized retaining rings are: equal cross-section, uniform stress, reduced stress concentration, smooth and complete inner and outer circles, non-interference with the inner and outer diameters of the mating parts, and no burrs. They are easy to disassemble and assemble, and almost no corner waste is generated during the production process. They save materials and do not require the production of molds. By changing the thickness of the materials, they can be easily made into light load, medium load, and heavy load types. The production cycle is short, and a wide range of materials can be selected, including spring steel and stainless steel, Copper and other metal materials can be easily produced.
