Conical rollers are divided into tapered upper self-aligning rollers and tapered lower self-aligning rollers. The tapered rollers have wear resistance and long service life. Light weight and low rotational inertia. Reasonable structure and reliable sealing. Excellent corrosion resistance.
Features of conical rollers:
The tapered idler has abrasion resistance, extremely low coefficient of friction, and it is not easy to wear the belt;
Excellent self-lubrication, no need for oil injection, not easy to be stuck under severe conditions;
With antistatic, anti-combustion resistance, aging resistance, acid, alkali and organic solvent corrosion resistance;
Able to withstand repeated shocks and vibrations; Operating temperature range: -40 ℃ -90 ℃;
Excellent mechanical performance, light weight, easy installation, no maintenance required;
Stable operation and long life.
Application range of conical roller:
Conical rollers are widely used in various transportation industries such as steel mills, power plants, docks, coal mines, etc. It has wear resistance, impact resistance, noiseless, antistatic, self-lubricating and not tearing conveyor belts, reducing resistance and suitable for long distance Conveying reduces energy consumption.
Three technological breakthroughs in cone rollers and friction rollers:
First, it was discovered that water and dust entering the labyrinth seal are a force principle.
Based on this principle, a labyrinth seal structure capable of cutting off such forces is designed to prevent water and dust from entering the outside. A labyrinth seal is used to ensure that the bearings in the cone rollers and friction rollers work in a good lubrication state for a long time. To reach its normal service life (calculated according to the bearing life formula, the normal service life of the bearing in the idler should be more than 150,000 hours).
, Break through the production and assembly technology of conical rollers and friction rollers.
It adopts the production technology that the two ends of the pipe body are not processed or welded, and the bearing seat is directly press-fitted with interference by taking the straightness of the pipe body and the inner diameter of the pipe as the reference. This production process is an unreasonable process in mechanical processing, but it is used in the production of idlers, which not only reduces the production process, reduces labor intensity, especially avoids the error of repeated clamping processing and welding deformation, Effectively ensure the consistency of the bearing positions at both ends of the roller, different axiality ≤0.05mm, so that the average rotation resistance of the roller is ≤1N, which is more than double the standard.
Third, the anti-corrosion and wear-resistant technology of the cone roller and friction roller tube.
1. The scrapped automobile tires are wrapped on the roller body without changing their physical properties, which changes the mechanism of friction and wear. The thickness of the adhesive layer is 14.5—38 (mm). It can be used for more than 60 months at the position where the steel tube idler is worn out for two months, which is dozens of times higher than the wear resistance of the steel tube idler. Especially the buffer idler produced by automobile tire rubber, the service life is also increased by more than ten times. 2. Moulded ultra-high molecular weight polyethylene idler roller with good accuracy, small resistance, light weight and high purity. Especially the wear-resistant, corrosion-resistant, flame-retardant, anti-static, non-sparking collision, and the prominent feature of avoiding gas explosion, it can be called a special roller in coal mine; In environments with severe wear and corrosion, as the shape rollers and friction rollers keep rotating flexibly, the tube body life can reach 50,000 hours, and in cement, mines, power plants, and docks can reach more than 100,000 hours.
