英国铁路和 Vandervell 公司经过四年的试验,决定在车辆上装用薄壁轴瓦(图1)。这种轴瓦是在厚4毫米的钢背上挂一层3毫米厚的铅基白合金。轴颈的尺寸为9吋×4(1/2)时(228.6毫米×114.3毫米)。轴瓦端部有凸缘以承受推力。质量试验表明,这种轴瓦可以在80公里 After four years of trial by British Rail and Vandervell, it was decided to mount a thin-walled bush on the vehicle (Figure 1). This bearing is a 4 mm thick steel back hung a 3 mm thick lead-based white metal. The size of the journal is 9 "x 4 (1/2) (228.6 mm x 114.3 mm). The end of the pad has a flange to withstand the thrust. Quality tests show that such bearings can be up to 80 km
