摘要:
The invention concerns a device comprising an element to be driven (10) and a driving element (250) designed to be urged into engagement with the element to be driven (10) and an actuating element (202) adapted to generate a reciprocating movement to move the driving element (250), the driving element (250) and the actuating element (202) being formed by etching in a semiconductor material block. The invention is characterized in that it is arranged such that: during a first alternation (a) of the movement generated by the actuating element (202), the driving element (250) is urged into engagement with the element to be driven (10) to pull the element to be driven (10), during a second alternation (b) in the opposite direction generated by the actuating element (202), the driving element (250) slides on the element to be driven (10), such that the element to be driven (10) is displaced in a step-by-step movement by the driving element (250).
摘要:
The invention relates to a drive device (10) formed by etching a wafer (11). Said drive device (10) comprises a drive element (250) that can sequentially mesh with a driven element (100, 104, 106) and comprises an actuating element (20, 40, 60) that can displace the drive element (250) according to a hysteresis movement whereby driving the driven element (100, 104, 106). The invention is characterized in the drive element (250, 270, 290) is placed on an outer edge of the wafer (11) whereby enabling an interfacing of the drive element with a driven element placed opposite therefrom. The invention also relates to a clockwork mechanism comprising a drive device of the aforementioned type and an input gear that can be rotationally driven by the drive device.
