Three technological breakthroughs in cone rollers and friction rollers:
1. It was discovered that water and dust entering the labyrinth seal is a force principle.
Based on this principle, a labyrinth seal structure capable of cutting off this force is designed, so that water and dust can never enter the outer labyrinth seal, ensuring that the bearings in the tapered rollers and friction rollers are in a good lubrication state for a long time. Work 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).
2. 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 axial degrees ≤0.05mm, making the average rotation resistance of the roller ≤1N, which is more than double that of international standards.
3. Anti-corrosion and wear-resistant technology of the cone roller and friction roller tube.
