With the rapid development of numerical control technology, machine tool industry is becoming more and more high to the requirement of precision bearing, mainly reflected in the high precision, high speed, high rigidity, high reliability, high adaptability, low noise, long life and so on.
Therefore, ZYS precision machine tool bearings made improvements and improve in the following aspects: 1, product design, finite element analysis method to the design and analysis method together, promote the best design technology;
Using simulation and all kinds of transient dynamics analysis model, steady-state analysis methods, optimize the bearing design;
According to different working conditions, the structure of bearing was improved, so as to adapt to different needs.
2 material using ZYS high-speed precision machine tool bearing ring usually selects the high quality, low oxygen content, non-metallic inclusion, organization, less fine electroslag remelting bearing steel, in order to improve the service life of the bearing;
Rolling material has high carbon chromium bearing steel and ceramic two kinds;
Cage material with phenolic resin, polyamide, high quality brass and non-ferrous metals, etc.
3 manufacturing process: heat treatment by quenching, washing and tempering temperature and time on the adjustment of process parameters, control, reduce the content of residual austenite in bearing ring;
Using the mesh belt furnace structure characteristics, through the quenching temperature and oil temperature adjustment, control, reduce the thermal stress when the bearing ring parts quenching, can greatly reduce the thin wall, deformation of large size model bearing ring parts;
Using carburizing, carbonitriding, cold treatment, ion implantation, surface coating, intermediate frequency quenching, bainite isothermal quenching and other advanced heat treatment process, can significantly improve the bearing ring parts impact toughness, microhardness, contact fatigue life, wear resistance and service life.
Parts processing: key control each link of the machining accuracy, efficiency and stability.
Anyhow, ZYS have professional complete bearing comprehensive technology supporting capacity, has bearing development, process design, equipment manufacturing, special testing method and instrument design, special bearing materials, rust, lubrication, failure analysis, noise analysis on bearing design, production and use of the whole process of comprehensive development ability, has the domestic leading level and in a number of key disciplines, to be able to solve the problem of bearing application under complicated conditions.
Take a number of national key projects supporting bearing task, all the year round for the country's important decision-making departments to provide bearing industry comprehensive technical advisory services.
