Abstract
A wobble drive mechanism for a translationally moving structural part includes a wobble rod which is moved by way of a crank drive mechanism. The wobble rod includes a spherical section at one end thereof that is seated in a bearing bush of a crank. At its opposite end, the wobble rod includes a second spherical section that is seated in a stationary structural part. A third spherical section is positioned between the two ends of the wobble rod and is seated in the translationally moving structural part. The spherical sections are supported in hemispherical articulation sockets located in the manner of a mirror image in the two structural parts. A spring device can be provided to ensure full contact of the spherical sections in their respective articulation sockets.
Claims4
A wobble drive for a structural part moving in translation and being maintained relative to a stationary structural part in a predetermined angular relationship, said stationary structural part having a bearing bush and said translationally moving structural part having a hub, said wobble drive comprising:
- a wobble rod;
- a crank drive mechanism for driving said wobble rod, said crank drive mechanism having an axis and a bearing bush;
- said wobble rod having a first spherical section mounted in the bearing bush of the crank drive mechanism;
- said wobble rod having a second spherical section mounted coaxially relative to the crank drive mechanism in an articulation socket of the bearing bush of the stationary structural part;
- said wobble rod having a third spherical section located between opposite ends thereof, said third spherical section being supported rotatingly and pivotingly in an articulation socket of a bearing bush in the hub of the translationally moving structural part;
- said bearing bushes for the second and third spherical sections being hemispherical articulation sockets located in the manner of a mirror image in the two structural parts;
- spring means for ensuring full contact of the second and third spherical section in their respective articulation sockets.
