Abstract
A flexible shaft arrangement is provided having a ductile shaft, a sleeve which surrounds the shaft as well as a jacket which surrounds the shaft and the sleeve. The sleeve extends within the jacket at least sectionally in arcuate form and thus produces a contact of the shaft at the inner contour of the sleeve point-wise. Vibrations or knocks of the shaft are thus effectively damped.
Claims13
A flexible shaft arrangement, comprising:
- a ductile rotating shaft,
- a non-rotating sleeve surrounding said ductile shaft and,
- a jacket surrounding the shaft and the sleeve, wherein the sleeve extends within the jacket along its length at least sectionally in arcuate shape differing from the longitudinal axis, axis of symmetry or center line of the jacket, and wherein the sleeve can move within the jacket, and wherein a plurality of individual spacers are formed of said sleeve in the radially outward direction, wherein directly mutually adjacent individual spacers are mutually offset angle-wise azimuthally about said sleeve from one another and are mutually axially spaced apart along the length of the sleeve from one another.
A flexible shaft arrangement, comprising:
- a ductile rotating shaft,
- a non-rotating sleeve surrounding said ductile shaft and,
- a jacket surrounding the shaft and the sleeve, wherein the sleeve extends within the jacket along its length at least sectionally in arcuate shape differing from the longitudinal axis, axis of symmetry or center line of the jacket, and wherein the sleeve can move within the jacket, and wherein a plurality of individual spacers are formed of said sleeve and are mutually axially spaced apart along the length of the sleeve from one another.
