一、发展原则改进现有装置的性能以及如有可能还要降低装置的成本,这永远是设计者的新任务。机车动车传动技术中的特殊目标是轻的重量,因为重量是衡量成本的尺度。在传动技术中,尺寸的大小,与其说是要满足扭矩的要求,倒不如说主要是满足性能的要求。在一定的扭矩下,达到较高转速的机器,其性能就是较佳的。性能是用户最主要的选择依据。 First, the development of principles to improve the performance of existing devices and, if possible, reduce the cost of the device, it will always be a designer’s new task. A special goal in locomotive drivetrain technology is light weight, as weight is a measure of cost. In the transmission technology, the size of the size, not so much to meet the torque requirements, might as well mainly meet the performance requirements. Under a certain torque, to achieve a higher speed of the machine, its performance is better. Performance is the user’s most important choice.
