Japanese Patent JP2013524544
Kind Code:
A
Abstract:
An indexing transmission for an on-load tap changer or a tap selector of a tapped transformer has a rotatable cam disk having an outer edge formed with a succession of convex and concave cam formations in regular succession and merging with one another, a crank transmission driving the cam disk, and a drive output disk acted on by the cam disk and having an outer edge. Engagement rollers rotatable on an end face of the drive output disk near the outer edge of the drive output disk roll on the outer edge of the cam disk. A switch shaft is rotationally fixed to the drive output disk such that the cam disk in cooperation with the engagement rollers of the drive output disk triggers a stepped rotation of the switch shaft through a defined step angle.
