Abstract
The invention relates to a drive rod for driving a movable contact element of a high-voltage switching device, wherein said drive rod comprises a first section for connecting said drive rod to a drive mechanism, a second section for connecting said drive rod to said movable contact element, and an intermediate section between said first section and said second section, characterized in that said intermediate section comprises coupling means for rotatably coupling said first section to said second section.
Claims13
A drive rod for driving a movable contact element of a high-voltage switching device, wherein the drive rod comprises a first section for connecting the drive rod to a drive mechanism, a second section for connecting the drive rod to the movable contact element, and an intermediate section between the first section and the second section, wherein the intermediate section comprises coupling means for rotatably coupling the first section to the second section so that the first section freely rotates with respect to the second section,
- wherein the coupling means comprise a bearing assembly having a bearing carrier, a first axial bearing arranged on the bearing carrier, and a second axial bearing arranged on the bearing carrier, wherein the first axial bearing and/or the second axial bearing is an axial ball bearing.
A method of manufacturing a drive rod for driving a movable contact element of a high-voltage switching device, wherein the drive rod comprises a first section for connecting the drive rod to a drive mechanism, a second section for connecting the drive rod to the movable contact element, and an intermediate section between the first section and the second section, wherein the following steps:
- providing the first section providing the second section, and coupling the first section to the second section with coupling means that are configured for rotatably coupling the first section to the second section so that the first section freely rotates with respect to the second section, providing the coupling means which comprise a bearing assembly having a bearing carrier, providing a first axial bearing arranged on the bearing carrier, providing a second axial bearing arranged on the bearing carrier, and wherein the first axial bearing and/or the second axial bearing is an axial ball bearing.
