ABSTRACT:
This specification discloses a bearing mounting device in which while the hydraulic pressure in a hydraulic mechanism for applying a preload to a bearing is being adjusted in a state in which the fixing sleeve of a fixing mechanism for fixing the bearing to a shaft has been expanded by hydraulic pressure, a predetermined preload is applied to the bearing through a spacer provided between the fixing mechanism and the hydraulic mechanism and through the fixing mechansim. The hydraulic pressure in the fixing mechanism is released with the predetermined preload being applied and the fixing sleeve is fixed to the shaft, whereby the bearing is fixed in its appropriately preloaded state.
