一、概述随着社会主义工业的不断发展,对各种机床设备的自动化和减轻劳动强度方面提出了越来越高的要求。由于液压装置具有自润滑性能和防锈性,能以较少的体积而获得较大的作用力或扭矩,动作迅速而平稳,容易实现无级调速,能够实现力、速度或方向的自动控制和远距离控制以及设备的过载保护等。因此,目前在各种机床设备中正得到愈来愈广泛的应用。 First, an overview With the continuous development of socialist industry, a variety of machine tool automation and reduce labor intensity put forward higher and higher requirements. Due to its self-lubricating and anti-rust properties, the hydraulic unit can obtain a larger force or torque with less volume, with quick and smooth movements, easy stepless speed regulation and automatic control of force, speed or direction And remote control and equipment overload protection. Therefore, a variety of machine tools are now being more and more widely used.
