Abstract
An adjustable power transmitting device comprising a rotary input shaft mounted for rotation about a first axis and an output shaft mounted for rotation about a second axis. The output shaft is also mounted for pivotal movement about at least two non-parallel axes so that the position of the output shaft can be adjusted about both of these axes. The input shaft is drivingly coupled to the output shaft so that the input shaft can rotate the output shaft in all positions of the output shaft about the two non-parallel axes.
Claims16
An adjustable power transmitting device for rotary motion comprising:
- a rotary input shaft;
- means for mounting the input shaft for rotation about a first rotational axis;
- a rotary output shaft;
- means for mounting the output shaft for rotation about a second rotational axis;
- second means for mounting the output shaft for pivotal movement about at least two non-parallel adjustment axes whereby the position of the output shaft can be adjusted;
- means for fixing said output shaft in any one of a plurality of positions about said adjustment axes;
- means for drivingly coupling the input shaft to the output shaft whereby the input shaft can rotate the output shaft in all positions of the output shaft about the two adjustment axes;
- said coupling means includes an input gear coupled to said input shaft, an output gear coupled to said output shaft and an intermediate gear drivingly engaging said input gear and said output gear, and means for mounting said intermediate gear for rotation;
- and
- said intermediate gear being a first intermediate gear and said coupling means includes a second intermediate gear drivingly engaging said input gear and said output gear, means for mounting said second intermediate gear for rotation, a first of said adjustment axes being perpendicular to said first rotational axis, and said two intermediate gears holding the output shaft against pivotal movement about said first adjustment axis.
