Document Type and Number:
Japanese Patent JP5074443
Kind Code:
B2
Abstract:
The invention provides a decelerator with an output pinion of a wind power generation system, which especially improves the bearing capability of the output shaft on one side opposite to the drive source side when dually supporting the output shaft of the decelerator with the output pinion of the wind power generation system. In the decelerator (G1) with the output pinion of the wind power generation system, the output shaft (32) is dually supported by a pair of bearings including an automatic aligning roller bearing (70) and a roller bearing (72); in the pair of bearings (70, 72), the roller(73) on one side opposite to the drive source side is composed of a plurality of rollers not only doing rotation but also doing revolution; and there has no roller (73) on the engaged window (74D) side.
