Abstract

The invention discloses a idler roller prepared by glass / aluminum matrix composite, comprising two bearings, two bearing chocks, a roller and an axis, the bearing chock and the roller are prepared by glass / aluminum matrix composite, the components of the glass / aluminum matrix composite and the weight percentage of each component are that: glass 7-30%, Aluminum 64-90%, crystal silicon 3-6%, the sum of the three is 100%. The glass / aluminum matrix composite idler roller, which is processed by the preparation technology of secondary hot extrusion and drawing, has the advantages of good comprehensive properties, i.e. low density, good conductivity, higher intensity and stiffness than rubber and plastic idler rollers and good anti-wear properties, more wear-resistance than the rubber and plastic idler rollers, not only greatly saving the energy consumption, reducing the cost, but also avoiding the occurrence of safety accident.

Description

technical field [0001] The present invention relates to an idler roller, in particular to an idler roller made of glass / aluminum matrix composite material and its preparation process, especially to a glass / aluminum matrix composite material mainly composed of waste glass and waste aluminum Rollers made of material. Background technique [0002] Idler rollers are the main accessories and consumables of belt conveyors, which are required to be wear-resistant, light in weight and conductive. The existing idlers are made of seamless steel pipe, rubber or plastic, and the main disadvantages are as follows: 1) The steel idler consumes a lot of steel, and the weight of the steel idler is large, and the power consumption of the motor is large ;2) Rubber or plastic idlers, because these materials are insulated, the static charge generated by the long-term friction between the conveyor belt and the idler cannot be introduced into the ground, and sparks will be generated when the char...
