九十一、液压传动的优缺点如何?液压传动是用液压来传递能量和进行控制的一种传动方式。液压传动与机械、电气传动相比较有如下优缺点:优点:传动平稳、冲击和振动较少,反应灵敏、操作省力,易于吸收冲击力和自动防止过载;能进行较大范围(可达2000:1)的无级变速,能实现连续或间歇运动;能获得较大的传动力及功率;在相同功率的情况下,液压传动装置体积小、重量轻、结构简单、惯性小;能获得各种复杂的动作,与电气或压缩空气相配合,可以实现各种各样的自动循环控制;能自行润滑,磨损小、元件寿命长;易于实现标准化、系列化。
Ninety-one, the advantages and disadvantages of hydraulic transmission? Hydraulic transmission is a hydraulic transmission of energy and control of a transmission. Hydraulic transmission and mechanical, electrical transmission compared to the following advantages and disadvantages: Advantages: smooth transmission, less impact and vibration, responsive, easy operation, easy to absorb the impact and automatically prevent overload; can be a large range (up to 2000: 1), continuous or intermittent movement can be achieved; greater transmission power and power can be obtained; in the case of the same power, the hydraulic transmission has the advantages of small volume, light weight, simple structure and small inertia; Complex movements, with electrical or compressed air to match, can achieve a wide range of automatic cycle control; to self-lubricating, wear small, long component life; easy to achieve standardization, serialization.
