1.游车柴油机不能稳定在一定的转速下工作,即转速经常上下波动,且有明显的感觉,此种现象称为“游车”。经长期使用的调速器,各机构或元件都有不同程度的磨损,各处的磨损值迭加起来,便出现了松旷现象,也就是说,机构内部出现空行程,进而引起齿杆移动迟缓,反应迟钝。再者,某元件装配不当或被异物污染,移动阻滞,均会导致齿杆移动不灵活,这是产生游车的主要原因。下述几方面,应认真对待,以确保机件处于正常技术状态,进而达到消除游车的目的。 (1)凸轮轴轴向间隙应保证在0.03～0.15毫米之间。此间隙可通过凸轮轴两侧垫片加以调整,调整毕
1. Trains diesel engine can not be stable at a certain speed, that is, the speed often fluctuate, and there is a clear feeling, this phenomenon is called “travel ”. Long-term use of the governor, various agencies or components have different degrees of wear and tear, wear the value of the superposition together, they appeared loose Kuang phenomenon, that is, the agency has an empty travel, which in turn caused the gear rod movement Slow, unresponsive. Furthermore, a component improper assembly or foreign body contamination, block movement, will lead to gear rack movement is not flexible, which is to produce the main reason for the car. The following aspects should be taken seriously to ensure that the mechanical parts in the normal state of technology, and thus to eliminate the purpose of the car. (1) Camshaft axial clearance should be guaranteed between 0.03 ~ 0.15 mm. This gap can be adjusted by both sides of the camshaft shims, adjust completed
