SHAFT ARRANGEMENT, AND SHAFT SUPPORTING METHOD

摘要

FIELD: machine building.SUBSTANCE: invention refers to the shaft that includes rotating shaft (4) that has hole (9) passing through it in longitudinal direction. In addition, the device includes bar (10) passing in longitudinal direction of shaft (4) through hole (9) from one end of shaft (4) to the other one. Bar (10) is provided on one end with radially directed supporting element (14). Supporting element (14) is located in axial direction after the end of shaft (4) and passes in radial direction beyond outer diameter of shaft (4) at the end. Supporting element has an axial inner surface with radially external part (142) and radially internal part (143). Radially external part (142) is offset in axial direction to shaft (4) relative to radially internal part (143). The invention also refers to the method of supporting shaft (4) by means of the above device.EFFECT: implementation of the shaft supporting so that the problems occurring from various thermal expansion coefficients of the shaft and the support structure can be eliminated or minimised.16 cl, 2 dwg
