One embodiment of the present invention provides an actuator comprising: a housing having a mounting space part formed therein; a motor part provided inside the housing and generating power; a reduction gear part of which a plurality of gears respectively having an internal gear and an external gear sequentially engage with each other so as to transmit the power generated in the motor part; and a rod part engaging with the gear disposed at the last position, and linearly moving according to the rotation of the gear, wherein one of the plurality of gears is formed such that the internal gear and the external gear can rotate together or rotate independently.

An electric power generation system according to one embodiment is characterized by converting, and storing as potential energy, renewable energy such as wind power and wave power, and thereafter driving an electric power generation device with the released energy. Specifically, a storage device 3 of an electric power generation system 1 is provided with a plurality of sets of weights 30 and pulleys 36, and a wire 37 is hung on the pulleys 36. When the renewable energy rotates a winder 35 in a winding direction, potential energy is stored according to the weight of the weights 30 and the rising distance of the weights 30. When the winder 35 becomes rotatable in a direction opposite to the winding direction, the stored potential energy is released, becomes continuous power according to gravity and acceleration of the weights 30, and turns a generator connected to the winder 35. According to the present invention, a large amount of power can be obtained for stably driving the electric power generation device, even in an unstable and intermittent renewable energy environment.

A gear wheel for a transmission includes a first member having a body for receiving a shaft and gear teeth for engagement with a further gear wheel, and a second member having a ring-shaped portion and teeth for engagement with a rotating component. The first member and the second member are rotationally locked relative to each other by means of an engagement means for transferring torque between the first member and the second member. The ring-shaped portion has a protrusion protruding in an axial direction in parallel with a rotational axis of the gear wheel and the body has an undercut receiving the protrusion. At least one part of the engagement means is arranged on the protrusion and inside the undercut.

A planetary transmission includes first and second ring gears and a double planet with first and second gears rotatably disposed about a common shaft and arranged such that the gear teeth of the first gear of the double planet engage into the gear teeth of the first ring gear, and the gear teeth of the second gear of the double planet engage into the gear teeth of the second ring gear. The first gear of the double planet is preloaded in a clockwise direction such that the gear teeth of the first gear of the double planet are in contact with the gear teeth of the first ring gear, and the second gear of the double planet is preloaded in a counterclockwise direction such that the gear teeth of the second gear of the double planet are in contact with the gear teeth of the second ring gear.

A transmission that suppresses a tilt of a slider in an axial direction and reduces a dimension of the slider in the axial direction for downsizing is provided. A transmission includes a fifth-speed driven gear disposed on a counter shaft, a fifth-speed driving gear that always meshes with the fifth-speed driven gear and disposed on a main shaft, and a first slider disposed on the counter shaft to be movable in the axial direction in accordance with a shift operation. The first slider includes first dog recesses. The fifth-speed driven gear includes fifth-speed dog projections configured to mesh with the first dog recesses. The fifth-speed driven gear includes a fifth-speed driven gear protrusion only on a location closer to a radially outer peripheral end thereof than the counter shaft. The fifth-speed driven gear protrusion protrudes in the axial direction so as to contact the first slider when the first slider falls in the axial direction. The protrusion length of the fifth-speed driven gear protrusion is smaller than that of the fifth-speed dog projections.

A clutch carrier assembly for a transmission is disclosed that comprises a clutch carrier and a ring gear carrier. The clutch carrier includes a plurality of tabs and the ring gear carrier includes a plurality of openings defined in, and extending through, an outer surface. The ring gear carrier is disposed within the clutch carrier. Each of the tabs is received within a corresponding one of the openings such that the ring gear carrier and the clutch carrier are held together.
