| 摘要 |
The invention relates to a device for translating a rotational motion into a rotationally oscillating motion. The device comprises A) a drive shaft (2) having a longitudinal axis (3), a rear end that can be linked with a drive unit, a front end (22) and a pin (6), disposed off-set on the front end (22) and having an axis (7) that is parallel to the longitudinal axis (3); B) a second, rotationally oscillating shaft (5) having a front end (23) that can be linked with a tool or an instrument, and a rear end (24); C) a transmission (1), disposed between the front end (22) of the drive shaft (2) and the rear end (24) of the second shaft (5), for translating the rotational motion of t he drive shaft (2) into the rotationally oscillating motion of the second shaft (5); and D) a housing (4) in which the drive shaft (2) and the second shaft (5) are mounted so as to rotate about the longitudinal axis (3); whereby E) the transmission (1) comprises a movable lever (9) which is movably mounted on the follower (12), on the housing (4) and on the pin (6), and whereby F) the lever (9) is disposed at an angle to the longitudinal axis (3). |
