车辆减速器是驼峰调车场的重要调速设备,通过对被溜放车辆的速度进行调节,最终实现与编组线上的停留车安全连挂。根据传动方式及工作原理,车辆减速器基本功能的实现体现为曲拐的偏心距l(mm)与传动压力(简称气压)P(MPa)和车重之间的关系。因此,作为车辆减速器的关键部件,曲拐的 Vehicle reducer hump yard is an important speed control equipment, by being put on the speed of the vehicle to be adjusted, and finally realize the line with the car on the car safety linked. According to the transmission mode and working principle, the realization of the basic function of the vehicle reducer is embodied as the relationship between the eccentricity l (mm) of the crank and the driving pressure (P) and the weight of the vehicle. Therefore, as a key component of the vehicle reducer, crank
