Problems solved by technology

This type of idler roller has poor sealing performance, and its lubricant is easy to evaporate and flow, so that the bearing is easy to wear and has a short service life; this type of idler roller cooperates with the conveyor belt, and it will generate electrostatic effect during use to stick materials and wear the conveyor belt; The roller is not resistant to acid and alkali corrosion, and the magnetic roller is easily damaged. These two kinds of rollers are heavy, and it is very inconvenient to transport and install.

Embodiment Construction

[0009] An electric bakelite idler. The outer tube 1 and the bearing seats 3 installed at both ends of the bakelite roller are all bakelite material products composed of glass fiber cloth and glue made of epoxy resin and phenolic resin. The rotating shaft 5 is inserted on the central axis 00' of the bearing seats 3 at both ends. The inner ball bearing 4 and the outer labyrinth combined seal 2 are fitted between the bearing seat 3 and the rotating shaft 5. The combined seal is composed of two seal ring components. The longitudinal half cross-sectional shape of one sealing ring assembly 7 is shaped, and the longitudinal half cross-sectional shape of the other sealing ring assembly 8 is shaped. They are interspersed with each other in the tortuous enclosed space formed in the middle to contain lubricating oil 9. Between the bearing 4 and the outer labyrinth combined seal 2 there is a circlip 6 which isolates them and is sleeved on the rotating shaft 5.

Abstract

The present invention is bakelite idler and its making process. The bakelite idler includes outer pipe, bearing seats on two ends, rotating shaft in the center, inner ball bearings and outer sealing parts between the bearing seats and rotating shaft and clamping spring to separate bearing seats from rotating shaft. The present invention features that the outer pipe and the bearing seats are made of bakelite comprising glass fiber fabric and mixture of epoxy resin and phenolic resin. The making process of the bakelite idler includes mixing and heating epoxy resin in 60-80 wt% and phenolic resin in 20-40 wt% as well as proper amount of triethanolamine to form glue, gluing glass fiber fabric, stoving, winding to form pipe, heating inside mold to form, cooling, demolding, and machining. The present invention has the advantages of high wear resistance, anticorrosion, long service life, light weight, etc.

Description

Technical field [0001] The invention relates to an idler roller used for a transportation conveyor belt, and specifically relates to an electric bakelite idler roller and a manufacturing method thereof. Background technique [0002] The rollers used in the conveyor belts of the existing mining, metallurgical, chemical and other enterprises are iron rollers or magnetic rollers. This kind of roller has poor sealing performance, and its lubricant is easy to evaporate and flow, so that the bearing is easy to wear, and the service life is short; this kind of roller and the conveyor belt will produce electrostatic effect during use and stick to the material and wear the conveyor belt; The roller is not resistant to acid and alkali corrosion, and the magnetic roller is easily damaged. These two types of rollers are heavier and inconvenient to transport and install. Summary of the invention [0003] The purpose of the present invention is to provide enterprises with a kind of bakelite r...
