Title:
HELICAL GEAR SUPPORT STRUCTURE, SPEED INCREASER FOR WIND POWER GENERATION PLANT, AND VERTICAL SHAFT SUPPORT STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2006/080127
Kind Code:
A1
Abstract:
A helical gear support structure, a speed increaser for a wind power generation plant, and a vertical shaft support structure. In the support structure supporting the shaft of a helical gear, the shaft of the speed increaser for wind power generation plant with the helical gear, or a vertical shaft by a double row rolling bearing, the double row rolling bearing is so formed that load capacities on the bearing in the right and left rows are different from each other so that the load capacity on the bearing in the row where the rolling bearing receives a large axial load can be increased.
