20080207377 | Oscillating internally meshing planetary gear system and method for manufacturing eccentric body shaft - The oscillating internally meshing planetary gear system has the configuration of rotating external gears inside an internal gear oscillatingly through the intermediary of eccentric bodies so that a relative rotation between the internal gear and the external gears is taken out through a pair of first and second carriers arranged on both axial sides of the external gears. In this configuration, eccentric body shafts are supported by the first and second carriers through needles. Thrust receiving means for restricting axial movement of the eccentric body shafts are arranged between step portions formed on the eccentric body shafts and the first and second carriers. | 08-28-2008 |
20110265593 | REDUCTION GEAR FOR WIND POWER GENERATION EQUIPMENT AND INSTALLATION METHOD THEREOF - A reduction gear for wind power generation equipment includes a motor, an orthogonal cogwheel mechanism, a final-stage reduction mechanism, and an output pinion that are disposed on a power transmission path in this order; and a casing that accommodates the orthogonal cogwheel mechanism and the final-stage reduction mechanism and is capable of being separated into a high-speed casing body and a low-speed casing body between the orthogonal cogwheel mechanism and the final-stage reduction mechanism while confining a lubricant therein. | 11-03-2011 |
20110269554 | POWER TRANSMISSION DEVICE AND JOINT UNIT OF POWER TRANSMISSION DEVICE - A power transmission device which transmits power between a first member and a second member, the first member has a hollow portion, the first member and the second member are fitted to each other by interference fitting by setting the external diameter of the second member so as to have a slightly larger size than the internal diameter of the hollow portion of the first member, and the surface of at least one of an inner periphery of the hollow portion of the first member and an outer periphery of the second member is subjected to a surface treatment in which slipping occurs when an excessive torque exceeding a predetermined value is applied, and the slipping stops and the original torque transmission to be performed in the power transmission device is performed again between the first member and the second member when the excessive torque is eliminated. | 11-03-2011 |
