| 要旨 | We have developed an angular contact ball bearing and a cylindrical roller bearing which are superior in low temperature-rise and high-speed performance for machine tool main spindles. By optimizing the internal design, temperature rise of both bearings has been reduced to approximately half compared with normal types. These bearings can reduce power consumption for cooling machine tools, which is effective for energy saving. And also, the developed bearings are expected to improve machining accuracy by reducing thermal expansion and improve machining effi ciency by increasing high-speed performance of spindles. |
