Product Description

The Tapered Roller is divided into conical centering roller and conical centering roller group. The Tapered Roller has wear resistance and long service life. Light weight and small rotation inertia. Reasonable structure and reliable sealing. Excellent corrosion resistance.
Characteristic
Tapered Roller has extremely high wear resistance and low friction coefficient, which is not easy to wear the belt;
Superior self lubrication, no oil injection, and it is not easy to get stuck under bad conditions;
Anti static, anti combustion, anti-aging, acid, alkali and organic solvent corrosion;
Can withstand repeated impact and vibration; Ambient temperature range: - 40 ºC - 90 ºC;
Excellent mechanical performance, light weight, easy installation, no maintenance;
Stable operation and long service life.
Scope of application
Tapered roller is widely used in various transportation industries, such as steel mills, power plants, wharves and coal mines. It has abrasion resistance, impact resistance, anti-aging, no noise, anti static electricity, self lubrication does not tear the conveyor belt, reduces resistance and is suitable for long distance transportation to reduce energy consumption.
Processing and production technology
1, The bearing seat is made of cast iron. The step holes are processed at both ends of the roller steel pipe, and then the bearing seat is press fit.
Its main defects are:
1. Unreasonable labyrinth structure and poor sealing performance;
2. The manufacturing accuracy is poor. After processing, the roundness of the inner step holes at both ends of the roller steel pipe meets the requirements, but the original out of roundness of the steel pipe cannot be eliminated;
3. The weight of the rotating part of the roller is large, resulting in the increase of the moment of inertia of the roller;
4. High labor intensity.
2, The bearing seat is formed by stamping with steel plate material, and then welded to both ends of the steel pipe by carbon dioxide gas shielded welding process.
Its main defects are:
1. The sealing performance can not achieve the most ideal effect;
2. The irregular deformation during welding will affect the coaxiality of the bearings at both ends.
In order to solve the disadvantages of the above-mentioned traditional roller, the new bearing seat of the roller is used to press the "nylon alloy" bearing seat and support ring directly with the roller steel pipe based on the good linear accuracy of the special high-frequency electric welding steel pipe for the roller (the bending degree of the 6m long steel pipe does not exceed 3mm) and the consistency of the circumferential wall thickness, The new roller production process without machining and welding is realized. The main advantages of this method are:
1. The coaxiality of the bearing positions at both ends of the roller is ensured, and the error is ≤ 0.05mm;
2. The interference press fitting of bearing seat and support ring can eliminate the out of roundness of steel pipe by about 60%, and the radial runout of outer circle is ≤ 0.3mm
3. Rotation resistance ≤ 1n;
4. Noise (at 1000r / min) ≤ 30dB;
5. The manufacturing accuracy of roller is effectively guaranteed, and the assembly qualification rate reaches 100%;
6. The mass of the rotating part is reduced by 1 / 3 and the moment of inertia is greatly reduced;
7. The production process is simplified, the labor intensity is reduced and the work efficiency is improved;
8. It changes the traditional sealing structure and realizes zero pollution and long-term normal operation in various harsh environments.
