Abstract
Official abstract text for this publication.
A handheld power tool gearbox unit, including at least one planetary gear stage, which includes at least one planet carrier, at least one planetary wheel, which is rotatably supported in relation to the planet carrier, and at least one bearing unit, which is provided to rotatably support the planetary wheel in relation to the planet carrier. The planetary wheel includes a pin, which rotatably supports the bearing unit in the planet carrier.
First claim
Opening claim text (preview).
1 - 10 . (canceled) 11 . A handheld power tool gearbox unit, comprising: at least one planetary gear stage which includes at least one planet carrier, at least one planetary wheel rotatably supported in relation to the planet carrier, and at least one bearing unit to rotatably support the planetary wheel in relation to the planet carrier; wherein the planetary wheel includes a pin which rotatably supports the bearing unit in the planet carrier. 12 . The handheld power tool gearbox unit as recited in claim 11 , wherein the at least one bearing unit is a roller bearing. 13 . The handheld power tool gearbox unit as recited in claim 11 , wherein the planetary wheel includes a base body and a pin element, which forms the pin. 14 . The handheld power tool gearbox unit as recited in claim 13 , wherein the base body and the pin element are at least rotatably fixedly connected to one another in one of a force-locked and a form-fitted manner. 15 . The handheld power tool gearbox unit as recited in claim 11 , wherein the at least one bearing unit includes an inner ring which is formed as one piece with the pin. 16 . The handheld power tool gearbox unit as recited in claim 11 , wherein the at least one bearing unit includes an outer ring which is formed as one piece with the planet carrier. 17 . The handheld power tool gearbox unit as recited in claim 11 , wherein the at least one bearing unit is a needle bearing. 18 . The handheld power tool gearbox unit as recited in claim 11 , wherein the at least one bearing unit is a ball bearing. 19 . The handheld power tool gearbox unit as recited in claim 11 , wherein the planetary wheel is a gearwheel and has a root diameter and the bearing unit includes at least one of a circular runway and a slideway, whose diameter is at least 50% of the root diameter of the planetary wheel. 20 . An electric handheld power tool device, comprising: at least one handheld power tool gearbox unit which includes at least two planetary gear stages, each of the at least two planetary gear stages including at least one planet carrier, at least one planetary wheel rotatably supported in relation to the planet carrier, and at least one bearing unit to rotatably support the planetary wheel in relation to the planet carrier, wherein the planetary wheel includes a pin which rotatably supports the bearing unit in the planet carrier.
