Abstract
Provided is a power transmission apparatus including pulley having an outer circumferential surface forming a predetermined angle; a power transmission member that is provided to surround the driving shaft and the outer circumferential surface of the pulley and transmits a rotational force of the driving shaft; and a driven part provided outward in a radial direction of the pulley and forming a pair of catching ends respectively surrounding the power transmission member in a direction opposite to each other. The power transmission apparatus may increase spatial efficiency and form a high gear ratio by reducing an overall profile by the pulley that rotates with the driven shaft in parallel using a belt or a wire, and a block and tackle or a half-moon member provided outside the pulley.
Claims8
A power transmission apparatus for transmitting power from a driving shaft that rotates by receiving power to a driven shaft that rotates by receiving the power of the driving shaft, the power transmission apparatus comprising:
- a pulley having an outer circumferential surface forming a predetermined angle;
- a power transmission member that is provided to surround the driving shaft and the outer circumferential surface of the pulley and transmits a rotational force of the driving shaft;
- and
- a driven part provided outward in a radial direction of the pulley and forming a pair of catching ends respectively surrounding the power transmission member in a direction opposite to each other.
