Abstract

A bearing arrangement of a helical spur gear which is non-rotatably arranged on a transmission shaft includes two conical sliding bearings configured for support of the transmission shaft. Each of the sliding bearings defines a cone angle, with the cone angle of one of the sliding bearings being different than the cone angle of the other one of the sliding bearings.

First claim

The invention is claimed is:

1. A bearing arrangement of a helical spur gear which is non-rotatably arranged on a transmission shaft, said bearing arrangement comprising two conical sliding bearings configured for support of the transmission shaft, each said sliding bearing defining a cone angle with the cone angle of one of the sliding bearings being different than the cone angle of the other one of the sliding bearings, wherein at least one of the sliding bearings comprises an inner bearing sleeve and an outer bearing sleeve with a lubrication gap formed therebetween, said inner bearing sleeve being arranged on the transmission shaft and having a radially outer circumferential face configured to form a cone-shaped sliding face, said outer bearing sleeve being configured to complement a configuration of the inner bearing sleeve.

2. The bearing arrangement of claim 1 , wherein the inner and outer bearing sleeves of the at least one of the conical sliding bearings define each a cone angle, with the cone angle of the inner bearing sleeve and the cone angle of the outer bearing sleeve being different.

3. The bearing arrangement of claim 1 , constructed in the form of a slew bearing.

4. The bearing arrangement of claim 1 , wherein the sliding bearings are arranged side by side on a same side of the spur gear and define tapered ends pointing toward each other.

5. The bearing arrangement of claim 4 , wherein the sliding bearings are arranged axially spaced apart from each other.

6. The bearing arrangement of claim 1 , wherein the sliding bearings are arranged on both sides of the spur gear, respectively, and define tapered ends pointing away from each other.

7. The bearing arrangement of claim 1 , further comprising an adjusting device operably connected to the at least one of the sliding bearings for adjusting the outer bearing sleeve in an axial direction in order to adjust the lubrication gap in a defined height.

8. The bearing arrangement of claim 1 , further comprising an adjusting device operably connected to only one of the sliding bearings for adjusting the outer bearing sleeve in an axial direction, said other one of the sliding bearings having an axially fixed position.

9. A transmission comprising
a transmission shaft;
a helical spur gear non-rotatably arranged on the transmission shaft; and
a bearing arrangement comprising two conical sliding bearings configured for support of the transmission shaft, each said sliding bearing defining a cone angle, with the cone angle of one of the sliding bearings being different than the cone angle of the other one of the sliding bearings, wherein at least one of the sliding bearings comprises an inner bearing sleeve and an outer bearing sleeve with a lubrication gap formed therebetween, said inner bearing sleeve being arranged on the transmission shaft and having a radially outer circumferential face configured to form a cone-shaped sliding face, said outer bearing sleeve being configured to complement a configuration of the inner bearing sleeve.

10. The transmission of claim 9 , wherein the inner and outer bearing sleeves of the at least one of the conical sliding bearings define each a cone angle, with the cone angle of the inner bearing sleeve and the cone angle of the outer bearing sleeve being different.

11. The transmission of claim 9 , wherein the bearing arrangement is constructed in the form of a slew bearing.

12. The transmission of claim 9 , wherein the sliding bearings are arranged side by side on a same side of the spur gear and define tapered ends pointing toward each other.

13. The transmission of claim 12 , wherein the sliding bearings are arranged axially spaced apart from each other.

14. The transmission of claim 9 , wherein the sliding bearings are arranged on both sides of the spur gear, respectively, and define tapered ends pointing away from each other.

15. The transmission of claim 9 , wherein the bearing arrangement comprises an adjusting device operably connected to the at least one of the sliding bearings for adjusting the outer bearing sleeve in an axial direction in order to adjust the lubrication gap in a defined height.

16. The transmission of claim 9 , wherein the bearing arrangement comprises an adjusting device operably connected to only one of the sliding bearings for adjusting the outer bearing sleeve in an axial direction, said other one of the sliding bearings having an axially fixed position.

17. The transmission of claim 9 , further comprising a member selected from the group consisting of a bearing cover and a housing, said outer bearing sleeve being a component of the member.
