摘要
在轴向柱塞泵中,滑靴的设计广泛的采用静压支承理论,从阻尼观点建立的流动模型来看,阻尼管型滑靴是靠液流经过固定阻尼和可变阻尼串联的油膜流动来实现静压支承的。为保证柱塞泵中滑靴副的静压支承设计的合理,必须对滑靴阻尼孔的结构尺寸选取合理的参数。文章在建立滑靴副的数学模型的基础上,通过采用改变滑靴阻尼孔结构尺寸,分析了阻尼孔直径和长度对滑靴的静压油膜和泄漏量的影响,提出了滑靴阻尼孔的设计方法。
Hydraulic static bearing technology has been widely adopted in design of slippers within the axial piston pump,from a flow model that establishing in the eyes of damping,hydraulic static bearing is realize using variable damping and constant damping series connection by the slipper of dampingtube type.In order to ensure reasonable design of hydraulic static bearing of the slipper,the structure size of damping hole in the slipper must select reasonable.Based on the establishment of mathematic model of the slipper,and by means of changeed size of the damping hole,this paper analyses the effect of diameter or length of the damping hole on the oil film and leakage,proposed design method of the damping hole.
