一、车轴用滚柱轴承的设计 1.轴承形式在让本,货车用密封型圆锥滚子轴承(图1),客车用圆柱滚子+球轴承(图2)、带挡边的圆柱滚子轴承(图3)和密封式圆柱滚子轴承(图4)。最新设计的电动车、内燃动车都采用密封式圆柱滚子轴承,因为它适合于车辆所要求的省力、轻量、可靠性高以及高速的特点。但国外其他国家的货车或电动车都采用与上述特点相同的密封式圆锥滚子轴 First, the design of the axle with roller bearings 1. Bearing the form Let the truck with sealed tapered roller bearings (Figure 1), the bus with cylindrical roller + ball bearings (Figure 2), with cylindrical roller Bearings (Figure 3) and sealed cylindrical roller bearings (Figure 4). The latest design of electric vehicles, diesel powered vehicles are used sealed cylindrical roller bearings, because it is suitable for the required vehicle effort, light weight, high reliability and high speed characteristics. However, other countries in the truck or electric vehicles are used with the same characteristics of the sealed tapered roller shaft
