Definitions
- the invention relates to a transmission with a housing.
- a gearbox has shafts that are rotatably mounted by means of bearings.
- a machine brake is known as the closest prior art from US 2021/0 071 727 A1.
- a gearbox is known from US 2021/0 041 017 A1.
- a lubricating device for a multi-stage transmission is known from EP 1 010 923 A2.
- a parallel shaft transmission is known from CN 1 01 799 069 A1.
- the invention is therefore based on the object of further developing the supply of the bearings of a transmission with lubricating oil.
- the object is achieved in the transmission according to the features specified in claim 1.
- Important features of the invention in the transmission are that the transmission with a
- Housing is formed, which has a lower part and an upper part connected to the lower part, bearing receptacles, in particular bearing receptacles designed as through bores, in particular for bearings of shafts of the transmission, being formed in the upper part, the lower part having an intermediate wall in which bearing receptacles, in particular, bearing receptacles designed as through bores, in particular for bearings of shafts of the transmission, are designed, the intermediate wall having plateaus (8, 9, 10), wherein a respective one of the bearing receptacles is arranged and/or inserted in a respective one of the plateaus, the Plateaus are delimited and/or spaced apart from each other by and/or outstanding storage edges (5, 6, 7) which rise in particular from the respective plateau towards the upper part.
- the advantage here is that the oil that drips down or flows along the inner walls is collected in the plateaus and fed to the bearings. This even makes it possible for the oil to build up on the plateau, meaning that the inclination of the plateau can be made negligible.
- the plateau can be designed to be flat, in particular horizontally aligned and flat. Nevertheless, the oil is supplied to the bearings, thus ensuring the supply of lubricant.
- An oil pump supplies the bearings located in the upper part.
- the bearings accommodated in the lower part do not require a special oil line; it is sufficient that the oil flowing or dripping down slides to the respective plateau and then supplies the respective bearing.
- the housing has cascade-like plateaus that function as an oil reservoir with a descending height, in particular with a descending distance from the upper part, which have storage edges that act as overflow edges and each at least one respective bearing receptacle, in particular for a respective one of the shafts rotatably mounted by means of bearings accommodated in the bearing receptacles of the upper part, in particular wherein the axes of rotation of the shafts rotatably mounted by means of the bearing receptacles and bearings accommodated therein are aligned parallel to one another and aligned parallel to the direction of the normal of the contact plane are.
- the advantage here is that the oil that drips down or flows along the inner walls is collected in the plateaus and fed to the bearings. This even makes it possible for the oil to build up on the plateau, meaning that the inclination of the plateau can be made negligible.
- the plateau can be designed to be flat, in particular horizontally aligned and flat. Nevertheless, the oil is supplied to the bearings, thus ensuring the supply of lubricant.
- An oil pump supplies the bearings located in the upper part.
- the bearings accommodated in the lower part do not require a special oil line; it is sufficient that the oil flowing or dripping down slides to the respective plateau and then supplies the respective bearing.
- the plateaus are inclined towards the bearing holder arranged in the respective plateau, in particular with an angle of inclination of less than 5°.
- each of the plateaus is aligned parallel to the split plane of the housing, in particular neglecting the inclinations of the plateau relative to the split plane, and in particular parallel to the contact plane between the upper part and the lower part.
- the plateaus have different distances from the split plane.
- the advantage here is that from a first plateau arranged closest to the split plane there is a further plateau with and dammed up in the first plateau overflowing oil can be supplied. Since a smaller bearing is arranged in the first plateau than in the further plateau, the corresponding bearing requires more oil than the smaller bearing. This applies accordingly to the third and/or additional warehouses.
- a respective hole is made in each plateau through the intermediate wall.
- an annular dam edge protruding from the upper part of the respective plateau delimits the respective bore from the respective plateau.
- the advantage here is that a maximum oil level is possible when the oil is dammed up.
- the ring-shaped dam edge protrudes further from the plateau to the split plane than the dam edge of the plateau.
- a respective plateau has a greater distance from the split plane than a plateau closest to the respective plateau.
- an oil sump of the transmission is arranged on the side of the intermediate wall facing away from the upper part.
- an oil pump of the transmission conveys oil, in particular from the oil sump, to bearings accommodated in the bearing receptacles of the upper part, in particular so that this oil drips down from the bearings accommodated in the bearing receptacles of the upper part to respective plateaus.
- the intermediate wall is the outer wall of the transmission.
- the plateaus can also be installed on the inside of an outer wall Gearbox housing can be formed.
- the bearings accommodated in the outer wall must then be covered from the outside by means of bearing caps, which are applied to the outside of the outer wall, and the oil must be drained away from the areas in the oil sump covered by the bearing caps, in particular by corresponding ones in the gearbox housing arranged and/or integrated channels or external pipelines, which, however, require additional installation space.
- each plateau is convexly curved.
- no tangential plane of the plateau is inclined more than 5° to the split plane of the housing.
- the axes of rotational symmetry of the bearing receptacles in particular the axes of rotation of the shafts rotatably mounted by means of the bearings accommodated in the bearing receptacles, are aligned vertically and/or perpendicular to the split plane.
- a cut transmission housing is shown in an oblique view in a first viewing direction, with the cutting plane aligned parallel to the split plane of the transmission housing.
- the cut transmission housing is shown in an oblique view in a second viewing direction.
- Shafts of the transmission can be rotatably mounted by means of bearings that can be accommodated in bearing receptacles (11, 12, 13, 14) of the lower part 1 and upper part 15.
- Gear parts can be connected to the shafts in a rotationally fixed manner and are in engagement with each other.
- an oil pump is provided, which supplies the bearings accommodated in the bearing receptacles of the upper part 15 with oil pumped by the oil pump, which then drips down to the lower part 1 or flows down the inner wall of the upper part 15.
- the bearing receptacles (11, 12, 13, 14) of the lower part 1 are installed in an intermediate wall, which has its longest extension essentially parallel to the split plane, i.e. to the contact plane between the lower part 1 and the upper part 15.
- the oil sump of the transmission from which the oil pump delivers the oil, is arranged on the side of the partition wall facing away from the upper part 15.
- the bearing receptacles (11, 12, 13, 14) are made as bores in a respective plateau (8, 9, 10) and pass through the intermediate wall.
- a first plateau 8 of these plateaus (8, 9, 10) is arranged closer to the split plane than a second plateau 9, which in turn is preferably arranged closer to the split plane than a third plateau 10.
- first bearing receptacle 11 In the first plateau 8 a first bearing receptacle 11 is introduced, in the second plateau 9 a second bearing receptacle 12 is introduced and in the third plateau 10 a third bearing receptacle 13 is introduced.
- the plateaus (8, 9, 10) are aligned essentially parallel to the split plane, and are preferably designed to slope slightly towards the bore made in them as a respective bearing holder (11, 12, 13).
- the angle of inclination to the split plane is always smaller than 5°.
- the first plateau 8 is delimited from the second plateau 9 by means of a storage edge 5, in particular an elevation, with the storage edge 5 rising towards the upper part 15.
- a shoulder is formed on the side of the storage edge 5 facing the second plateau 9.
- the second plateau 9 is delimited from the third plateau 10 by means of a storage edge 6, in particular an elevation, with the storage edge 6 rising towards the upper part 15.
- a shoulder is formed on the side of the storage edge 6 facing the third plateau 10.
- the third plateau 10 also has a storage edge 7 for the fourth bearing holder 14.
- the limitation of the oil collected in the first plateau is achieved by the side walls of the lower part and the storage edge 5.
- the oil reaches the first plateau 8 by dripping and/or falling and/or flowing down the inner walls of the lower part 1. Only that portion of the oil that flows over and/or spills over the first reservoir edge 5 reaches the second plateau 9.
- the limitation of the oil collected in the second plateau 9 is also determined by the
- the limitation of the oil collected in the third plateau 10 is also achieved by the side walls of the lower part and the storage edge 7 as well as the shoulder arranged on the first storage edge 6.
- these ring-shaped and/or the storage edges protrude from the respective plateau (8, 9, 10).
- the split plane is aligned horizontally and/or the axes of rotation of the shafts supported by the bearings accommodated in the bearing receptacles (11, 12, 13, 14) are aligned vertically.
- the first bearing receptacle 11 has a smaller clear inner diameter than the second bearing receptacle 12.
- the second bearing receptacle 12 is the closest bearing receptacle to the first bearing receptacle 11.
- the second bearing receptacle 12 has a smaller clear inner diameter than the third bearing receptacle 13, which is adjacent to the second bearing receptacle 12.
- the third bearing receptacle 13 has a smaller clear inner diameter than the fourth bearing receptacle 14, which is adjacent to the third bearing receptacle 13.
- the intermediate wall is designed as an outer wall of the transmission and thus the supply of oil to the bearings according to the invention is carried out via the plateaus of different heights on the outer wall.
- the holes (2, 3, 4) and their storage edges are omitted and the oil pump is supplied from the oil sump that forms around the fourth bearing receptacle 14.
