Abstract

A gear unit is provided having a housing, that has a pot-like lower part and a cover plate mounted on it, the lower part having a bottom plate, the bottom plate having a bearing cross that accommodates bearings, especially the bearings of the shafts of the gear unit, the cover plate having a further bearing cross that accommodates bearings, especially the other bearings of the shafts of the gear unit.

First claim

1 .- 12 . (canceled)

13 . A gear unit, comprising:
a housing that includes a pot-like lower part and a cover plate mounted on the lower part, wherein:
the lower part includes a bottom plate,
the bottom plate includes a bearing cross that accommodates bearings, and
the cover plate includes a further bearing cross that accommodates further bearings.

14 . The gear unit as recited in claim 13 , wherein the bearings are of shafts of the gear unit, and wherein the further bearings are of the shafts of the gear unit.

15 . The gear unit as recited in claim 13 , wherein at least one of the bearings are disposed in one line and the bearings are disposed in a main trunk of the bearing cross.

16 . The gear unit as recited in claim 13 , further comprising:
a frame, wherein the bottom plate includes fins that are joined at a first end of each fin to a frame and with another end of each fin each fin is joined to the bearing cross of the bottom plate

17 . The gear unit as recited in claim 16 , wherein the fins are aligned parallel to each other.

18 . The gear unit as recited in claim 16 , wherein the frame includes a U-shaped frame.

19 . The gear unit as recited claim 13 , wherein the bottom plate includes a plurality of base plates joined to a frame of the bottom plate, wherein the gear unit is able to be erected on an installation surface with the base plates.

20 . The gear unit as recited in claim 13 , wherein the lower part includes U- shaped plates which join the bottom plate to a flange frame facing away from the bottom plate, the cover plate being mounted on and joined to the flange frame.

21 . The gear unit as recited in claim 20 , wherein the cover plate includes wall sections situated between the bearing cross of the cover plate and a flange frame of the cover plate.

22 . The gear unit as recited in claim 21 , wherein the wall sections are thinner- walled than the bearing cross of the cover plate.

23 . The gear unit as recited in claim 20 , wherein the lower part includes side-wall sections that on one side are joined to the flange frame of the lower part, and on another side, to at least one of the bottom plate and the U-shaped plates.

24 . The gear unit as recited in claim 13 , wherein a window is provided in a cutout in a side-wall section of the lower part, and covers the cutout.

25 . The gear unit as recited in claim 13 , further comprising a window frame delimiting a cutout in a side-wall section of the lower part and welded to the side-wall section, wherein an adhesive agent is provided between the side-wall section and the window frame.

26 . The gear unit as recited in claim 25 , further comprising a window at least one of screwed onto the window frame and tightly joined to the window frame with a sealing device located in between, wherein the window is made of steel and is not transparent.

27 . The gear unit as recited in claim 20 , further comprising a pin disposed on at least one of a connecting section and the flange frame, wherein a safety bracket for a carrying cable is located on the pin.

28 . The gear unit as recited in claim 23 , wherein at least one of the U-shaped plates is disposed outside of at least one of the side-wall sections.

29 . The gear unit as recited in claim 20 , wherein lateral sides of two of the U- shaped plates are at least one of transverse and perpendicular to each other.

30 . The gear unit as recited in claim 29 , wherein a first of the two U-shaped plates is disposed on a front side of the gear unit, and wherein another of the two U-shaped plates is disposed on a side of the gear unit.
