旅客运输的舒适性,在许多情况下,与单车供电,包括车轴发电机传动装置的工作情况有关。因此,提高传动装置的可靠性具有很重要的意义。车轴发电机的三角皮带-变速箱-万向轴传动装置经受各种载荷的作用,首先是承受齿轮变速箱反力矩的作用(即皮带拉力加大或减小)、交变的扭矩作用和皮带轮的松动作用等。车辆运行中传动装置两皮带轮中心距和皮带拉力的周期性变化会引起皮带的横向松动,结果在皮带上产生交变符号的附加应力,导致皮带的过早破裂。关于三角皮带寿命的现行规定自相矛盾。譬如,按车辆段的运用数据,一辆车每年需要皮带5副(20根),而现有定额却只有2副。皮带不足必然会导致客车设备技术保养细则(Ty 104 )中规定的配套要求不能执行。传动装置经常处在皮带不整套
Passenger transport comfort, in many cases, relates to the cycling power supply, including the operation of the axle generator drive. Therefore, it is very important to improve the reliability of the transmission. The V-belt drive of the axle generator-gearbox-cardan shaft is subjected to a variety of loads. The first is to withstand the reaction of the gearbox (ie, increase or decrease of the belt tension), the alternating torque action and the pulley The role of loose and so on. Periodic changes in center distance between pulleys and belt tension in the running gear of the vehicle can cause lateral loosening of the belt, resulting in an additional sign of alternating sign on the belt, resulting in premature rupture of the belt. The current rules regarding the life of the V-belts are self-contradictory. For example, according to the depot usage data, a car needs five belts (20) a year, while the current quota is only two. Insufficient belts will inevitably lead to the implementation of the matching requirements specified in the Technical Instructions for the Maintenance of Bus Equipment (Ty 104). Transmission often in the belt is not the whole set
