Abstract

A housing for a gear unit includes a housing top part mounted on a housing bottom part, a first bearing mounting for a first bearing of a shaft being formed by a first bearing carrier of the housing top part and a first bearing carrier of the housing bottom part, a second bearing mounting for a second bearing of a shaft being formed by a second bearing carrier of the housing top part and a second bearing carrier of the housing bottom part, a first end area of a first bearing carrier of the housing bottom part and a first end area of a second bearing carrier of the housing bottom part being joined by two end plates set apart from each other.

First claim

What is claimed is:

1. A housing for a gear unit, comprising:
a housing top part mounted on a housing bottom part;
a first bearing mounting for a first bearing of a shaft being formed by a first bearing carrier of the housing top part and a first bearing carrier of the housing bottom part; and
a second bearing mounting for a second bearing of a shaft being formed by a second bearing carrier of the housing top part and a second bearing carrier of the housing bottom part;
wherein a first end area of the first bearing carrier of the housing bottom part and a first end area of the second bearing carrier of the housing bottom part are joined by two end plates set apart from each other.

2. The housing according to claim 1 , wherein a second end area of the first bearing carrier of the housing bottom part and a second end area of the second bearing carrier of the housing bottom part are joined by two end plates set apart from each other.

3. The housing according to claim 1 , wherein a first end area of a first bearing carrier of the housing top part and a first end area of the second bearing carrier of the housing top part are joined by two end plates set apart from each other, and a second end area of the first bearing carrier of the housing top part and a second end area of the second bearing carrier of the housing top part are joined by two end plates set apart from each other.

4. The housing according to claim 1 , wherein at least one of the end plates of the housing top part contacts one of the end plates of the housing bottom part.

5. The housing according to claim 1 , wherein between end plates of the housing top part, which are joined at the first end areas of the bearing carriers of the housing top part, spacers are disposed, and/or between end plates of the housing bottom part, which are joined at the first end areas of the bearing carriers of the housing bottom part, spacers are disposed.

6. The housing according to claim 1 , wherein the bearing carriers of the housing bottom part are joined by supporting bars and/or supporting sections to base plates of the housing bottom part, in order to dissipate a weight force of the bearing carriers.

7. The housing according to claim 1 , wherein the bearing carriers, end plates, spacers, supporting bars, supporting sections, and base plate of the housing bottom part are implemented integrally, in one piece, and/or as a steel casting.

8. The housing according to claim 1 , wherein the bearing carriers, end plates and spacers of the housing top part are implemented integrally, in one piece, and/or as a steel casting.

9. The housing according to claim 1 , wherein the end plates extend further in one direction that is aligned perpendicular to a direction corresponding to a furthest extension of the bearing carriers, and/or supporting bars and/or supporting sections extend mainly in a direction aligned perpendicular to the two directions.

10. The housing according to claim 1 , wherein the housing bottom part is arranged as a shell, remaining areas of the housing bottom part having a smaller wall thickness than a wall thickness of the end plate, the bearing carriers, supporting sections, and/or supporting bars.

11. The housing according to claim 2 , wherein a first end area of a first bearing carrier of the housing top part and a first end area of the second bearing carrier of the housing top part are joined by two end plates set apart from each other, and a second end area of the first bearing carrier of the housing top part and a second end area of the second bearing carrier of the housing top part are joined by two end plates set apart from each other.
