近年来,有关机器—拖拉机組高速作业的科学研究結果指出:当机組工作速度提高到5—9公里/小时时,将大大提高生产率、降低金屬消耗、节約劳动力和生产費用。但机組工作速度若进一步提高,也将产生一些不良后果:机具作业质量下降,能量消耗增多,机組工作可靠性降低,劳动条件恶化和机組起步困难等。 本文的任务就是通过理論分析与試驗研究解决高速机組起步困难的問題。 拖拉机的起步不同于汽車,一般是接近于滿载,且在任何速档(包括高档)直接起步,因
In recent years, the scientific research on the high-speed operation of tractor-tractor units has pointed out that when the working speed of the generating units is increased to 5-9 km / h, the productivity will be greatly increased, the consumption of metal will be reduced, labor and production costs will be saved. However, if the working speed of the unit is to be further increased, there will be some adverse consequences: the quality of operation of the equipment is reduced, the energy consumption is increased, the reliability of the working of the unit is reduced, the working conditions are deteriorated and the starting of the unit is difficult. The task of this paper is to solve the problem of difficult start-up of high-speed units through theoretical analysis and experimental research. Tractor start different from the car, usually close to full load, and in any gear (including high-grade) direct start, because
