Document Type and Number:
WIPO Patent Application WO/2012/133535
Kind Code:
A1
Abstract:
Provided is an energy-storing mechanism with a forcing mechanism which is inexpensive and simple and in which load torque is suppressed and stable operation is possible. Also provided is an on-load tap changing device provided with same. The forcing mechanism incorporated in the energy-storing mechanism is configured from a projection (8), a bearing (9), and an entry cam (17). Of these, the projection (8) is attached to the lower side of the eccentric cam (2), and the bearing (9) is attached to the tip of the projection (8). The entry cam (17) has the shape of an isosceles triangle with a vertex angle near 90° and is attached to the upper side of the energy-storing case (5). By making contact with the bearing (9), the entry cam (17) rotates the crank (6) via the energy-storing case (5) and sends the catch (7) to the standby position.
