ELASTIC ROLLER TYPE CLUTCH

摘要

The present invention relates to a power transmission clutch which transmits rotational power. The power transmission clutch includes a first clutch body (600) configured to receive rotational power from an input shaft to be rotated; and a second clutch body (700) configured to transmit the rotational power received from the first clutch body (600) to an output shaft. When a power transmission roller (630) touches clutch rotating pieces (750) as the first clutch body (600) is rotated, the clutch rotating pieces (750) are rotated to push an elastic roller (730); while the clutch rotating pieces (750) touch each other between the power transmission roller (630) and the elastic roller (730) to be compressed, the rotational power of the first clutch body (600) is transmitted to the second clutch body (700); when load that is more than a predetermined size is transmitted from the output shaft in a process of transmitting rotational power, the clutch rotating pieces (750) move back while pushing the elastic roller (730) to cause a slip effect that the power transmission roller (630) climbs over the clutch rotating pieces (750).
