苏联塔什干铁路运输工程师学院和中亚西亚铁路局研制了一种不拆卸机车牵引电动机轮对组的预检轴承和齿轮传动装置的试验台,其结构特点是,轮对以其轮箍的轮缘顶部支承在滚轮上,在运动中使其经受最小磨耗。试验台的结构如下:滚轮轴13的支座1(图1)沿周边焊在上板2上,它把轮对的负载从一侧经滚子21,而从另一侧经盘形弹簧叠片3传递给中板6。盘形弹簧叠片用螺栓5拉紧。中板6经辊子19支持在下板7上,而用焊在下板上的定位器20阻止辊子19轴向移动。在轴13上压装滚轮8、№62326双排球面滚柱轴承内圈10和各有12个余弦线型面凸轮的凸轮盘14。轴承用轴承盖9盖住,轴承盖用拧在螺柱
Tashkent Railway Transportation Engineering Institute of the Soviet Union and the Central Asia Railway Bureau developed a non-disassembly locomotive traction motor wheel set of pre-inspection bearings and gear transmission test stand, the structural features of the wheel is its wheel rim The top is supported on the roller and is subjected to minimal wear during motion. The structure of the test stand is as follows: The support 1 (FIG. 1) of the roller shaft 13 is welded circumferentially to the upper plate 2, which loads the wheelset from one side via the roller 21 and from the other side via the disc- Sheet 3 is passed to the middle plate 6. The disc spring was tensioned with bolts 5. The middle plate 6 is supported on the lower plate 7 via the roller 19 while the axial movement of the roller 19 is prevented by the retainer 20 welded to the lower plate. Roller 8, No. 62326 double-row spherical roller bearing inner ring 10, and cam plate 14 each having 12 cosine line type cam are press-fitted to shaft 13. Bearings with bearing cover 9 cover, bearing cap screwed to the stud
