Improvement of the Pulling Out Method for Inner Ring of Axle Bearing on the 300 Series Shinkanson Electric Car

介绍了 30 0系新干线电车车轴轴承的拔出方法及改进措施 ,采用中空车轴 ,对车轴进行冷却 ,改进感应加热器对轴承内圈加热 。

The pulling out method and improvement measures for the inner ring of axle bearing on the 300 series Shinkanson electric car are described.The hollow axle is applied,the axle is cooled,the improved induction heater is used to heat the bearing inner ring,so that it can be pulled out easily. Key words:bearing inner ring; pulling out; Japan颍澹恚澹欤? sensitive of late years,site vibration test method is accredited generally bec ause it can proffer comparable quantitat ive dates and qualitative description.A vibration test all over process of resid ential housing in the range of influence brought out by execution of a emphasize d engineering and assessment method is i ntroduced and some reasonable suggustion s to execution parameters through test a re put forward in this paper.
