POWER TRANSMISSION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/156361
Kind Code:
A1
Abstract:
The present invention relates to a power transmission apparatus. The power transmission apparatus (10) according to the present invention is provided with a drive unit (100) for providing a rotational force. A power transmission unit (200) is connected, with a weight (M) fixed thereto, with the drive unit (100). The power transmission unit (200) reciprocates the weight linearly in the direction of the drive unit (100) as the length thereof increases and decreases according to the rotation directions of the drive unit (100). A weight restoration unit (300) is provided between the power transmission unit (200) and the weight (M). The weight restoration unit (300) moves the weight (M) away from the drive unit (100) if the power transmission unit (300) is restored to the original state. The drive unit (100) is connected to a control unit. The control unit plays the role of driving the power transmission unit (200) by controlling the drive unit (100). Configured as such, the present invention has a high driving force and, at the same time, allows the volume and weight thereof to be minimized and can have a simple structure.
