【摘要】 为使大型三轴试验机横梁实现大行程升降,提出一种新型光杠自锁升降装置,其原理是通过与立柱相联结的可涨开过盈弹性套和可锁紧开口弹性套与提升油缸的交替运动实现横梁的"无限"导程;并使用增压器解决过盈弹性套所需的高压。更多还原

【Abstract】 A new-style slick pole self-lock up-down setting was designed to realize large size up-down of crossbeam of 3-axial test machine,its principle was that crossbeam’s limitless pass was realized by alternate motion of overtop elastic cannula and ringent elastic cannula connected with poles.High pressure was realized by turbocharger.更多还原
