Document Type and Number:
Japanese Patent JP3614694
Kind Code:
B2
Abstract:
A crankshaft directly connected to an electric motor and operably connected to a drive load is supported at two locations with bearings that are respectively subject to different amount of bearing loads. A resilient member is interposed between the inner race of one or both of the bearings and the crankshaft for applying an axial pre-load to the bearings. The weight of the crankshaft and the rotor, and/or a magnetic attractive force generated in the electric motor is/are applied to the bearing as an axial pre-load in addition to the pre-load by the resilient member.
