| Abstract: | Based on the general situation of metro vehicle axle box bearing in China,combined with the structural characteristics of axle box bearings,the bearing for type standardization is selected.This paper presents the advantages of type standardization bearing,that is a compact tapered bearing with a dimension of 130 mm (inner diameter)× 230 mm (outer diameter)×150 mm (width).With sufficient theoretic calculation,experimental validation and running service,the type standardization bearing has been applied in domestic type A metro vehicle,type B metro vehicle and overseas multiple units,covering the speed grade from 80 km/h to 160 km/h and the axle load from 14 t to 19 t. |
