no. 1 Embodiment approach

[0019] A rotating shaft portion for inputting a driving force for driving a movable part of the power generator is inserted into a through hole formed in a drive gear meshing with a driven gear provided on the movable part of the power generator. In many cases, the through hole is formed to be larger than the cross section of the rotating shaft in order to easily insert the rotating shaft into the through hole. This is due to play between the drive gear and the rotating shaft portion. The play between the drive gear and the rotary shaft portion generates inclination of the drive gear about an orthogonal axis orthogonal to the rotation axis of the rotary shaft portion. The inventors of the present invention have found that the inclination of the drive gear around the orthogonal axis can cause wear and other damage to the drive gear and / or the driven gear. In the first embodiment, a technique for reducing the inclination of the drive gear around the orthogonal axis will be desc...

Abstract

The present application discloses a driving device for driving a driven gear provided on a movable part of a power generating device that generates power in response to changes in the flow direction of fluid. The driving device includes: a driving gear meshing with the driven gear; and a driving portion having a rotating shaft portion penetrating through a through hole formed in the driving gear. The drive gear has an inner wall surface that forms an outline of the through hole. The rotation shaft portion is in pressure contact with a first virtual plane perpendicular to the rotation axis of the rotation shaft portion and a second virtual plane separated from the first virtual plane in a direction in which the rotation axis extends. the inner wall surface.

Description

technical field [0001] The invention relates to a drive device for driving a power generating device. Background technique [0002] A wide variety of power generating devices are known for converting the kinetic energy of a fluid into electrical energy. For example, windmill equipment converts kinetic energy of air into electric energy (see JP-A-2013-209991 and JP-A-2005-233055). Japanese Patent Laid-Open No. 2013-209991 and Japanese Patent Laid-Open No. 2005-233055 disclose a spline coupling structure between a pinion gear meshing with a ring gear of windmill equipment and a shaft of a speed reducer. [0003] Since the power generating device needs to continuously generate electric power (for example, for a period of 20 years or more), the power generating device is desired to have a maintenance-free structure compared with ordinary mechanical equipment. When a normal spline coupling structure is used for driving a power generator, misalignment between the pinion gear and...
