Abstract
A planetary gearing for a robot gearing arrangement includes a sun gear, a ring gear, and a planet carrier with at least three planetary gears rotatably mounted thereon. The planetary gears are arranged on planet pins arranged perpendicular to the planet carrier and are in meshing engagement with the sun gear and the ring gear. At least one first planetary gear is biased in a first circumferential direction and/or at least one second planetary gear is biased in a second circumferential direction. A first planet pin of the first planetary gear is at least partially elastically deformable in the second circumferential direction and/or the second planet pin of the second planetary gear is at least partially elastically deformable in the first circumferential direction.
Claims17
A planetary gearing for a robot gearing arrangement, comprising a sun gear, a ring gear, and a planet carrier with at least three planetary gears rotatably mounted thereon, each planetary gear arranged on respective planet pins arranged perpendicularly to the planet carrier, each planetary gear in meshing engagement with the sun gear and the ring gear, wherein at least one first planetary gear of the at least three planetary gears is biased in a first circumferential direction wherein a planet pin of the first planetary gear is at least partially elastically deformable in a second circumferential direction, and wherein the first and second circumferential directions are arranged opposite one another.
The planetary gearing according to claim 9, wherein at least one third planetary gear is provided which is not biased.
The planetary gearing according to claim 9, wherein each of the planetary gears is biased in either the first circumferential direction or in the second circumferential direction.
A planetary gearing, comprising:
- a sun gear;
- a ring gear;
- a planet carrier;
- and
- first, second, and third planet gears rotatably mounted on planet pins fixed to the planet carrier, each of the first, second, and third planet gears meshing with the sun gear and the ring gear;
- wherein
- the planet pins are unequally spaced circumferentially and the planet pin supporting the first planet gear is deformable such that the first planet gear is biased in a first circumferential direction to reduce lash between the planet gears and the sun and ring gears.
