Definitions
- the invention relates to an eccentric bearing sleeve, the two ends store in a roller gear housing, for, in this on both ends, eccentrically mounted roller supporting shafts with one on the outside of the bearing attachable roller ring and arranged between the shaft ends, through a circumferential recess of the bearing sleeve with a meshing drive wheel also mounted in the roller gear housing, splined shaft sections.
- this type of training requires those held by the supporting structure in the roller gear housing inner eccentric bearing sleeve section of this support structure to solve, and from the other eccentric bearing sleeve section as well subtract from the end of the roller supporting shaft facing away from the rolling ring. Then, after pulling off the rolling ring from the bearing outer end of the support shaft, this from the other, in the peripheral wall of the rolling gear housing eccentric bearing sleeve section be pulled out inside.
- the replacement the replacement roller shaft is carried out in the reverse order the described expansion steps.
- This inventive design of the eccentric bearing sleeve and the roller shaft allows a roller shaft after loosening the Axial displacement protection in the roller gear housing in the simplest way outwards from the eccentric bearing sleeve remaining in the roller gear housing pull out and the replacement roller shaft as well simply insert it from the outside into the eccentric bearing sleeve.
- the rolling ring located on each of the support shafts can be in its roll-adjusted position remain on the support shaft.
- the eccentric bearing sleeve can this form of training be formed in one piece.
- the eccentric bearing sleeve consists of the Sleeve sections 1a and 1b.
- the sleeve portion 1a is stored in the Outer wall 2a of the roller gear housing 2 and has an eccentric bearing 1a 'on.
- the eccentric bearing sleeve section 1a is the eccentric bearing sleeve section 1b scheduled; this has an eccentric bearing 1b 'and is supported by the support structure 2b of the roller gear housing 2 worn.
- the roller support shaft 4 with its ends 4a and 4b.
- the roller supporting shaft 4 can only be removed, when the eccentric sleeve portion 1b in the direction of arrow P from the end facing away from the rolling ring 5 4b after loosening the Axialverschiebeêt 3 from the end facing away from the rolling ring 5 4b of the roller support shaft 4 has been removed and the roller ring 5 itself was removed.
