Embodiment
As Fig. 1, shown in Fig. 2, the rotor assembly of small-power turbosupercharger peculiar to vessel, it comprises turbine 1, seal ring 2, floating bushing 3, axle 4, seal ring 5, shaft seal 6, pinch roller 7, turbine 1 is fixed on one end of axle 4, both are fixed by friction welding, axle 4 passes the other end and pinch roller 7 spline joint of turbine intermediate housing 10, floating bushing 3 by both sides between axle 4 with intermediate 10 coordinates, shaft seal 6 is fixed between pinch roller 7 and axle 4, seal ring 2 be located at the socket cap outer surface of turbine 1 and shaft seal 6 outer surface annular groove and in, the axle journal root of the connection spline sides of axle 4 and pinch roller 7 is located at by seal ring 5, pinch roller 7 side is fixed on shaft end by fastener assembly.
As shown in Figure 2, Figure 3, Figure 4, pinch roller 7 and axle 4 spline joint, axle 4 forms rotor with turbine 1 is fixing, and rotor is supported by two floating bushings 3 and is positioned at middle 10; Shaft seal 6 is located at the floating bushing outer end of pinch roller side, this shaft seal right side leans against on the step surface of axle 4, left side leans against in the plane of pinch roller 7 blade back side, fastener assembly comprises nut and pad, nut 9 is screwed to the left side of axle 4 to be fixed pinch roller 7 by internal thread, pad 8 is located between pinch roller 7 and nut 9, the step root of axle 4 is enclosed within the end face groove that seal ring 5 is located at shaft seal 6, this step root is axle journal root, axle journal root and seal ring joint are set to fillet 5a, and fillet 5a place is provided with seal ring 5 and leaks to external leakage to prevent the lubricant oil of bearing arrangement
As shown in Figure 1, turbine 1 is provided with cavity 1a with the joint of axle 4, and the thermal conductivity of this cavity 1a is significantly less than the material at high temperature alloy of axle 4, and the heat making turbine end conduct to floating bushing side greatly reduces.
As shown in Figure 2, the left end of axle 4 is provided with spline 4a, and the axle journal intermediate portion that axle 4 installs floating bushing 3 is set to the necking segment 3a that diameter reduces 1mm; Under normal circumstances, the tolerance arranging the axle journal of floating bushing is 0.008mm, and this undergauge section is without cooperation component, and tolerance is 0.1mm, this reduces the difficulty of processing of axle.
As shown in Figure 4, shaft seal 6 end face is provided with the counterbore 6a for embedding sealing circle, can arrange seal ring 5 to prevent the fluid of bearing lubrication system to external leakage.
As shown in Figure 5, floating bushing 3 end face is provided with oil film wedge face 3b, can bear radial load.
As Fig. 6, Fig. 7, Fig. 8 pad 8 is provided with splined hole 8a, can with the spline joint of axle 4, can't rotate relative to axle 4, this pad being also provided with being parallel to of two place's symmetries axially can to the locking plate 8b of flange perpendicular to axial direction; Nut 9 is provided with the straight trough 9a of two place's symmetries.During assembling, the end face 8c of pad 8 leans against on the end face 9b of nut 9, and cylindrical 8d is enclosed within the middle of the endoporus 9c of nut 9, and locking plate 8b aligns with the straight trough 1 of nut 9, and locking plate to the direction flange perpendicular to axis, can so just reach the effect that locking nut prevents from loosening.
