Abstract

A hydraulic pump includes a pump mechanism (12) having a driven shaft (16). The driven shaft (16) is connected to an input shaft (50) by a flexible coupling such as a splined connection. A housing (30) extends completely around the driven shaft (16), and a high-pressure seal (74) is disposed between the housing (30) and the input shaft (50). A thrust bearing (72) carries hydraulic axial forces on the input shaft (50) to the housing (30). This arrangement provides balanced hydraulic forces on both ends (18, 20) of the driven shaft (16), thereby reducing friction and wear.
