Abstract
A power tool gear device has at least one first and one second gear stage, and a switching element which may be moved by an operator using an actuating element. The switching element at least partially surrounds at least one gear stage in at least one operating position along a circumferential direction and is configured to switch between a first and a second operating position. The switching element includes at least one first component and one second component.
Claims16
A power tool gear device, comprising:
- a first gear stage;
- a second gear stage;
- and
- a switching element configured to be moved by an operator using an actuating element, wherein the switching element at least partially surrounds at least one of the first and second gear stages in at least one operating position along a circumferential direction, and wherein the switching element is configured to switch between a first operating position and a second operating position, and wherein the switching element includes a switching ring, and
- an elastic element,
- wherein the switching ring has a first locking element configured for non-rotatable connection of the switching ring to a housing in the first operating position, a second locking element configured for rotatable connection of the switching ring to a planetary carrier in the second operating position, and at least one supporting element projecting radially inwardly towards the ring gear,
- wherein the ring gear has an inner toothed structure and at least one supporting element projecting radially outwardly towards the switching ring,
- wherein the elastic element is supported on the at least one supporting element of the switching ring by one end and on the at least one supporting element of the ring gear by an opposite end
- such that the elastic element is configured to provide a relative movement between the switching ring and the ring gear.
