Abstract
Official abstract text for this publication.
A hand power tool device includes at least one drive unit, which has at least one drive shaft. The hand power tool device also includes at least one transmission unit which has at least one transmission element that is directly connected to the drive shaft. The hand power tool device also includes at least one cooling unit which has a fan element. The fan element is at least substantially directly connected to the at least one transmission element of the at least one transmission unit.
First claim
Opening claim text (preview).
What is claimed is: 1. A hand power tool device comprising: at least one drive unit including at least one drive shaft; at least one transmission unit including at least one transmission element that is directly and fixedly connected to the at least one drive shaft; and at least one cooling unit including at least one fan element, wherein the at least one fan element is at least substantially directly connected to the at least one transmission element of the at least one transmission unit. 2. The hand power tool device according to claim 1 , wherein the at least one transmission element is pressed on to the at least one drive shaft. 3. The hand power tool device according to claim 1 , wherein the at least one fan element is pressed on to the at least one transmission element. 4. The hand power tool device according to claim 1 , wherein the at least one transmission element has at least one toothing. 5. The hand power tool device according to claim 4 , wherein: the at least one transmission element includes at least one region which at least partially includes the at least one toothing, and the at least one transmission element includes at least one at least substantially cylindrical region. 6. The hand power tool device according to claim 5 , wherein the at least one fan element is at least partially disposed in the at least one at least substantially cylindrical region. 7. The hand power tool device according to claim 1 , wherein the at least one fan element is composed at least substantially of a plastic. 8. The hand power tool device according to claim 1 , wherein the at least one fan element has at least one stop element at least substantially configured to at least substantially prevent a relative motion between the at least one fan element and the at least one transmission element in at least one of an axial direction and a circumferential direction. 9. A method for producing a hand power tool device comprising: connecting a transmission element of a transmission unit directly to a drive shaft of a drive unit; and connecting a fan element of a cooling unit to the transmission element. 10. A hand power tool comprising: a hand power tool device including: at least one drive unit having at least one drive shaft; at least one transmission unit having at least one transmission element that is directly connected to the at least one drive shaft; and at least one cooling unit having at least one fan element, wherein the at least one fan element is at least substantially directly connected to the at least one transmission element of the at least one transmission unit. 11. A hand power tool device comprising: at least one drive unit including at least one drive shaft; at least one transmission unit including at least one transmission element that is directly connected to the at least one drive shaft; and at least one cooling unit including at least one fan element, wherein the at least one fan element is at least substantially directly connected to the at least one transmission element of the at least one transmission unit, wherein the at least one transmission element is pressed on to the at least one drive shaft. 12. A hand power tool device comprising: at least one drive unit including at least one drive shaft; at least one transmission unit including at least one transmission element that is directly connected to the at least one drive shaft; and at least one cooling unit including at least one fan element, wherein the at least one fan element is at least substantially directly connected to the at least one transmission element of the at least one transmission unit, wherein the at least one fan element has at least one stop element at least substantially configured to at least substantially prevent a relative motion between the at least one fan element and the at least one transmission element in at least one of an axial direction and a circumferential direction.
