Title:
MOTIVE-POWER TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/157276
Kind Code:
A1
Abstract:
Provided are a pulley (4) connected to a motive power source, and a rotating shaft positioned coaxially with respect to the pulley (4). Also provided are a hub (11) provided to the rotating shaft, and a ring plate (12) separably mated to the hub (11). Also provided is a leaf spring (16) for urging the ring plate (12) toward the hub (11) in the direction parallel to the axis of rotation. When the load on the rotating shaft is below a threshold, the hub (11) and ring plate (12) are caused to rotate as a single entity due to friction. When the load on the rotating shaft is equal to or higher than a threshold, the ring plate (12) rotates in relative fashion with respect to the hub (11) and moves parallel to the axis of rotation due to the spring force of the leaf spring (16), so that the ring plate (12) and the hub (11) separate. It is possible to provide a power transmission device in which power transmission is quickly interrupted after the load torque on a driven-side rotating element has increased.
