一、容积式液力传动的特点容积式液力传动,就其本身的性质而言,运动工况指标(如位移、速度等)与负荷工况指标(如力、转短等)无关,因此可将其用在各种控制系统里;譬如,要能承受变动疾风而将飞机稳定在固定航线上的自动驾驶操纵系统、不因外部负荷变化而引起既定的运动规律被破坏的机床仿型系统等,以达到对各种机器的手动或自动控制(本文不分析这方面的内容)。而另一方面,我们只要在液压系弦及元件的结构上采取适当措施,又可使其运动工况指标与负荷工况指标发生必要的联系,以满足各种调速系统的要求;这就是说,容积式液力传动又可以用在各种机器的传动机构中,譬如,要求充分利用原动机潜力的等功率调速的内燃机车或拖拉机的驱动机构中及等志矩调速的炮塔迴转机构中等。容积式液力传动具有上述性能,加以它能无级调
First, the characteristics of positive displacement hydraulic drive Positive displacement hydraulic drive, in terms of its own nature, sports conditions indicators (such as displacement, speed, etc.) and load conditions indicators (such as force, short turn, etc.) has nothing to do with It can be used in a variety of control systems; for example, an automatic piloting system that can withstand a fluctuating blast and stabilizes the aircraft on a fixed route, a machine tool profiling system that does not cause a predetermined pattern of motion to be destroyed due to changes in external loads Etc., in order to achieve the manual or automatic control of various machines (this article does not analyze this aspect). On the other hand, as long as we take appropriate measures in the structure of the hydraulic chords and components, we can make the necessary connection between the index of the working condition and the indicator of the load condition to meet the requirements of various speed governing systems; Said volumetric hydraulic transmission can also be used in a variety of machine transmission, for example, require full use of the potential of the prime mover and other power-speed diesel locomotive or tractor drive mechanism and the turret speed control turret Medium transfer agencies. Volumetric hydraulic transmission with the above performance, to be able to stepless it
