Document Type and Number:
Japanese Patent JP7042176
Kind Code:
B2
Abstract:
This rotor blade support structure for an electrical generator rotatably supports a vertical axis type rotor blade (1) and transmits the rotation of the rotor blade (1) to an electrical generator (2) located below the rotor blade (1). A circular cylindrical bearing case (4) is rotatably mounted on the outer periphery of the case (5) of the electrical generator (2) through ring-shaped bearings (9, 9). The bearing case (4) is coaxially joined to the rotor blade (1) and is connected to the electrical generator shaft (2a) of the electrical generator (2). The bearing case (4) is provided with a circular cylindrical case body (4a) and an end plate (4b) which is provided at one axial end of the case body (4a) and to which the rotor blade (1) is joined.
