无铰轴向柱塞泵是一个空间五杆机构,由主轴、连杆、柱塞、缸体和泵壳五个杆件组成。在油泵设计中,连杆副(包括柱塞和连杆)是无铰机构的关键,其送动和受力都比较复杂,它既是一对摩擦副,又是一对传动副。在实际使用中,油泵的失效往往发生于连杆的折断。为此,必须高度重视连杆副的设计。一、连杆副的运动分析在油泵的五杆机构中,连杆对活塞有摆动和自转,这是相对运动。同时连杆和柱塞一起
Hingeless axial piston pump is a space five-bar mechanism, the spindle, connecting rod, plunger, cylinder and pump shell composed of five bars. In the oil pump design, the connecting rod pair (including the plunger and connecting rod) is the key of the hingeless mechanism. Its transmission and force are more complicated. It is not only a pair of friction pair but also a pair of transmission pair. In actual use, the pump failure often occurs in the connecting rod break. To this end, we must attach great importance to the design of connecting rod. First, the link deputy motion analysis In the pump five-bar mechanism, connecting rod swing and rotation of the piston, which is the relative movement. At the same time connecting rod and plunger together
