Title: INTERMITTENT TRANSMISSION MECHANISM
Abstract:
An intermittent transmission mechanism comprising a driving rotating body (6) adapted to rotate along with an input shaft (9) and a driven rotating body (3) adapted to rotate along with an output shaft (8). The driven rotating body (3) has arcuate recesses (1) and a gear (2). The driving rotating body (6) has a partial gear (4) adapted to mesh with the gear (2) of the driven rotating body (3) to drivingly rotate the driven rotating body (3) at predetermined angles in an intermittent manner, and a cam portion (5) provided with a rotation restricting surface (5a) which moves relatively along arcuate surfaces (1a) of the arcuate recesses (1). Provided around the cam portion (5) of the driving rotating body (6) are guide grooves (24) for guiding balls (24) in contact with the arcuate recesses (1) of the driven rotating body (3). The partial gear (4) and the cam portion (5) on the driving rotating body (6) are displaced along the axis of rotation, and the gear (2) and the recesses on the driven rotating body (3) are displaced along the axis of rotation.
