Abstract
PURPOSE:To prevent the abrasion and the burning of the seal section, by providing an axial oil supply groove in the outer-circumferential face of a rotor shaft to be supported by a sliding bearing then performing the lubrication of said bearing and the control of the cooling and the vane back pressure reliably thereby reducing the gap of the bearing. CONSTITUTION:An oil supply groove 29 are made axially such that it will bevel the outer-circumferences of rotor shafts 4a, 4b. Consequently the lubrication to the sliding bearing is improved while the flow path resistance of the lubrication oil passing through the bearing gap can be varied thereby the vane back pressure functioning on the vane bottom chamber 9 can be controlled. Said oil sup- ply groove 29 can be formed easily in the outer circumferential faces of the rotor shafts 4a, 4b through the surface grinding where the depth (H) is finished accurately with micron order to enable the improvement of the control accuracy of the flow path resistance. Consequently the gap of the sliding bearing 5 can be reduced resulting in the prevention of the abrasion and the burning of the tangent seal section.
