【技术实现步骤摘要】
本技术涉及液压加载领域,特别地,涉及一种推力轴承试验台液压加载装置。
技术介绍
目前,大型推力轴承试验台需要稳定和大推力的加载力,因此,对加载装置的要求比较高。以往的推力轴承试验台设计中由于被试主泵轴承加载时轴瓦与镜板间会产生一定的变形,从而产生轴向间隙,这种情况下加载装置便不能对主轴施加稳定与精确的轴向推力。现有技术中静压轴承靠主轴一侧高温润滑油无法快速流出会导致静压轴承温度过高,从而影响静压轴承的性能。
技术实现思路
本技术提供了一种推力轴承试验台液压加载装置,旨在补偿被试主泵轴承运行时产生的轴向间隙以及解决静压轴承流入主轴一侧的高温润滑油无法快速流出导致静压轴承温度过高的问题。为实现上述目的,本技术的实施例提供了一种推力轴承试验台液压加载装置,包括:推力盘、箱体、安装在箱体内的加载油缸和随动油缸,推力盘与主轴通过平键固定连接,加载油缸通过螺栓固定在箱体上,随动油缸可上下移动地套在加载油缸内,加载油缸与随动油缸配合形成密闭的加载油腔,加载油腔通过O型密封圈密封。进一步地,随动油缸底部开设环形油腔并与推力盘配合形成静压轴承。进一步地,加载油缸与静压轴承分别通过加载 ...
