<p>The proposed converting mechanism is provided with a stepping wheel (1) of annular shape that is provided in its upper portion with teeth (2) running during rotation of the stepping wheel (1) by their tips to a rest position (5.2) and incentive surface (5.1) of a first run-on disk (5) being coupled with the shaft (4) of a pendulum (10). Owing to this, a displacement motion in one direction is imparted to the shaft (4) and the pendulum (10). The teeth (2) further run to a rest position (6.2) and incentive surface (6.1) of a second run-on disk (6) being arranged reversely and therefore the shaft (4) and the pendulum (10) perform displacement motion in opposite direction. So a swing of pendulum (10) without reversing motion is achieved. In order to achieve easier and slower run of a tooth (2) tip onto the rest position (5.2) and incentive surface (5.1), the teeth (2) are provided with leading edges with radius (R).</p> |
