Description
Technical Field
The utility model relates to a retarder with a housing part and a cover.
Background
It is known to arrange lubricating oil in the interior of the gear unit for lubricating the intermeshing teeth.
SUMMERY OF THE UTILITY MODEL
The object of the utility model is therefore to improve the reduction gear as compactly as possible.
According to the utility model, this object is achieved by a retarder according to the following features.
In the case of a gear unit having a housing part and a cover, an important feature of the utility model is that the housing part is formed with a bulge which protrudes, in particular, over the surface of the housing part and encloses a surface region of the housing part,
in particular, wherein the bulge is formed as a thickening of the housing part,
wherein a finished surface, in particular a flat surface, in particular a surface serving as a sealing surface, is formed on the bulge,
wherein the cover is connected with the shell component,
wherein a seal, in particular a planar seal, arranged on the face is arranged between the cover and the face,
wherein a spatial region or gap is defined by the cover and the surface region and the ridge,
wherein a bearing cap is arranged in the spatial region,
wherein the bearing cap is connected to the housing part and rests on a further surface which is formed on a further elevation, in particular as a flat and/or finished further surface,
wherein the other side is designed to be interrupted.
The advantage here is that the oil can be efficiently dissipated by collecting it in the spatial region serving as an intermediate buffer reservoir, since the spatial region is designed to be flat and the cover can be designed with cooling ribs. In this way a good heat transfer of the oil towards the surroundings can be provided. Furthermore, the delivered air flow flows along the cover and thereby improves the heat dissipation.
Thus, high power can be achieved with a small installation space of the reduction gear, i.e. the reduction gear can be designed compactly.
In an advantageous embodiment, the surface on which the cover rests, in particular the sealing surface, completely surrounds without interruption in the circumferential direction relative to the axis of rotation of the intermediate shaft. The advantage here is that the sealing is simple and effective. Furthermore, the spatial region is thus sealed off from the surroundings. Furthermore, the surface provides good support for the cover or seal, so that the connection can be made with a high level of protection.
In an advantageous embodiment, a threaded bore is formed in the surface, into which threaded bore a threaded part is screwed, the head of which presses the cover against the housing part. The advantage here is that a simple, cost-effective fastening can be achieved. The threaded bore is oriented parallel to the axis of rotation of the intermediate shaft, i.e. in particular parallel to the normal direction of the plane which is designed to be flat.
In an advantageous embodiment, the gear unit has an intermediate shaft which is rotatably mounted, wherein the other face is designed to be interrupted, in particular not completely surrounded, in the circumferential direction with respect to the rotational axis of the intermediate shaft. The advantage here is that the interruption region enables the oil to flow through. Since the bearing cover delimits the outer ring of the first bearing of the countershaft in the axial direction, i.e. in particular in the direction of the rotational axis of the countershaft, the oil flows through the interruption region to the first bearing of the countershaft of the gear reducer.
In particular, the other face is formed with two interruptions which are diametrically opposed to one another, in particular with reference to the axis of rotation of the intermediate shaft. Thus, the oil flows through the two interruption regions to the first bearing of the intermediate shaft and thus a further improved lubrication can be achieved.
In an advantageous embodiment, the recess of the housing part, which serves as the first oil channel, leads from the spatial region through the region of the other face, which is designed as a break, to the first bearing of the intermediate shaft. The advantage here is that the lubrication of the first bearing of the intermediate shaft is improved. The bearing can therefore also be arranged above the oil level and can nevertheless be supplied with oil at least during operation of the gear unit. The second bearing of the intermediate shaft is arranged in the oil sump of the gear unit.
In an advantageous embodiment, a recess is formed in the housing part as a further oil channel, which leads from the spatial region to the first bearing of the output shaft. The advantage here is that the lubrication of the first bearing of the output shaft is improved. The first bearing can therefore also be arranged above the oil level and can nevertheless be supplied with oil at least during operation of the gear unit. The second bearing of the output shaft is arranged in the oil sump of the gear unit.
In an advantageous embodiment, a recess serving as a third oil duct is formed in the housing part, which recess leads from the spatial region to the first bearing of the input shaft, in particular wherein the first bearing is designed as a double bearing, in particular wherein the recess serving as the third oil duct leads centrally between two bearings of the double bearing of the input shaft. The advantage here is that the bearing can be received in a pot-shaped bearing seat which can be inserted in a prefabricated manner with adjusted bearing stress into a recess of the housing part. Although the bearing is inaccessible for oil from the oil sump, the oil is well supplied by the supply via the third oil channel according to the utility model.
In an advantageous embodiment, the recess serving as the third oil duct has a branch formed in the housing part, which branch leads between the first bearing and the second bearing of the input shaft. The advantage here is that a sufficient supply of all bearings of the input shaft can be ensured.
In an advantageous embodiment, the intermediate shaft drives a suction pump which delivers oil into the spatial region via an oil line and/or via a channel which is formed in the housing part. The advantage here is that the suction pump is driven passively.
In an advantageous embodiment, the suction pump is arranged on the side of the second bearing of the intermediate shaft facing away from the first bearing of the intermediate shaft. The advantage here is that the suction pump is arranged in the oil sump of the gear unit and can thus achieve suction with low effort.
In an advantageous embodiment, the first bearing of the intermediate shaft and the first bearing of the output shaft are arranged above the oil level when the gear unit is permanently at rest/is not operating. The advantage here is that a sufficient supply of lubricating oil can be achieved by means of the oil channel formed in the housing part, i.e. inside the housing part.
In an advantageous embodiment, the input shaft is connected to the fan in a rotationally fixed manner, wherein the air flow delivered by the fan is guided along the cooling ribs of the cover. The advantage here is that cooling can be carried out efficiently and thus high power can be achieved with a small installation space of the gear unit, i.e. the gear unit can be designed compactly.
In an advantageous embodiment, a fan guard surrounding the fan is detachably connected to the housing part, in particular wherein the fan guard guides the air flow conveyed by the fan along the cooling ribs of the cover. This has the advantage that heat dissipation can be carried out efficiently.
In an advantageous embodiment, the cooling ribs are oriented parallel to the axis of rotation of the input shaft. The advantage here is that effective heat dissipation can be achieved.
In an advantageous embodiment, a seating region is formed on the housing part, which seating region is arranged on the side of the housing part facing away from the cover. The advantage here is that the output shaft can project, in particular, be vertically oriented, on the side facing away from the base part when the base part is standing on a horizontal ground.
The utility model is not limited to the combination of features described above. The above-described combinations of features and/or other possible combinations of features described individually and/or of features described below and/or of features of the drawings may be made available to the person skilled in the art, in particular as a result of the objects set forth and/or by comparison with the prior art.

Detailed Description
As shown in the figures, the gear unit according to the utility model has an input shaft 12, the bearing of which is received in a bearing flange, which is connected to the housing part 1 by means of screws.
An input shaft 12 designed as a toothed pinion meshes with a gear wheel 9, which is connected in a rotationally fixed manner to the intermediate shaft 5.
The intermediate shaft 5 is preferably vertically oriented.
The input shaft 12 is oriented perpendicularly to the countershaft 5, in particular because the input gear stage of the reduction gear is a bevel gear stage.
A further toothed segment is machined directly on the intermediate shaft 5 or on a gear wheel connected in a rotationally fixed manner to the intermediate shaft 5, which further toothed segment meshes with a further gear wheel connected in a rotationally fixed manner to the output shaft 8.
The output shaft 8 is oriented parallel to the intermediate shaft 5.
At least one of the bearings of the output shaft is received in the housing part 1.
The bearing 2 of the intermediate shaft 5 is likewise received in the housing part.
On the housing part 1, in particular on the upper side of the housing part 1 as viewed in the vertical direction, a bulge protruding in particular in the vertical direction is formed which encloses or extends along the periphery of a surface area of the housing part 1, on which a finished surface serving as a sealing surface 31 is provided, on which the cover 3 is placed, wherein a sealing element, in particular a flat sealing element, arranged between the cover 3 and the sealing surface 31 seals off a spatial region covered by the cover 3 and designed between the cover 3 and the housing part 1.
A suction pump 20 driven by the intermediate shaft 5 sucks oil arranged in the interior of the gear unit, in particular from an oil sump, and delivers the oil via an oil line 21 which leads to a channel arranged in the housing part 1.
The channel preferably consists of radial bores 22, 24 and an axial bore 23, which are referenced to the axis of rotation of the intermediate shaft, and opens into the space region.
This spatial region thus forms an oil reservoir, in particular an intermediate buffer reservoir. From this space region, the bearings of the output shaft 8 on the one hand and the bearings of the intermediate shaft 5 and also the bearings of the input shaft 12 are then fed through further channels.
The cover 3 has cooling ribs on its outer side, so that the oil located in the space region efficiently dissipates heat towards the surroundings.
The bearing cap 4 is placed on a further sealing surface 30 of the housing part 1, which is likewise arranged on a further bead formed on the housing part 1, which bead in particular projects in the vertical direction and encloses a partial region of the surface region of the housing part 1. The further sealing surface 30 is finished. The bearing cap 4 is placed on the further sealing surface 30 and is fixed to the housing part 1 by means of a screw which penetrates the bearing cap 4 and is screwed into a threaded hole which is machined in the further sealing surface.
A seal, in particular a flat seal, can optionally be arranged between the bearing cap 4 and the further sealing surface 30. However, the leaktightness at the other sealing surface is not harmful, since the leaked oil flows down to the bearing of the intermediate shaft 5 and thus contributes to the lubrication and cooling of this bearing.
On the one hand, a control bearing 6 is received in the bearing cover 4, which is permeable to oil and thus enables an oil flow from the spatial region through the control bearing 6 to the bearing 2 axially below the control bearing in the direction of the axis of rotation of the intermediate shaft 5. Lubrication and cooling of the bearing 2 can thereby be ensured.
Alternatively or additionally, a further oil flow from the space region to the bearing 2 can be achieved in that the further sealing surface 30 is not designed to completely surround in the circumferential direction of the rotational axis of the intermediate shaft 5, but rather is designed to be interrupted. In this interruption region, a distance is produced between the bearing cap 4 and the housing part 1, so that oil can enter there and can penetrate in particular through the bearing cap 4 to the bearing 2 of the intermediate shaft 5. A first oil channel is formed here, which leads from the spatial region through the interruption region to the bearing 2 of the intermediate shaft 5.
A threaded bore is also machined in the sealing surface 31, into which a screw is screwed, the screw head of which presses the lid 3 against the sealing surface 31 and which protrudes through the lid 3.
A recess serving as a further oil channel 16 is formed in the housing part 1, which recess leads from the spatial region to the bearing of the output shaft 8.
A third oil channel for lubricating oil is provided in the housing part 1, which preferably consists of radial bores 13, 15 and an axial bore 14 with reference to the rotational axis of the input shaft. This third oil channel opens on the one hand into the space region and on the other hand into a region which is arranged centrally between the two bearings of the first bearing of the input shaft 12, which is designed as a double bearing 17. Improved lubrication of the double bearing can thus be achieved.
The double bearing 17 is preferably received in a pot-shaped bearing seat, which is connected to the housing part 1 by means of a screw. However, the bearing seat protrudes from the housing part 1 towards the surroundings, so that the double bearing 17 is insufficiently supplied with lubricant for the lubricating oil from the oil sump without the lubrication provided by the third oil channel.
The perpendicular projection of the double bearing 17 in a plane containing the axis of rotation of the input shaft 12 and having its normal direction oriented parallel to the axis of rotation of the intermediate shaft 5 is arranged outside the perpendicular projection of the housing part 1 in this plane or overlaps the perpendicular projection of the housing part 1 in this plane. Therefore, the lubricating oil is difficult to enter the double bearing 17 from the oil sump. However, the third oil channel can convey the lubricating oil directly from the space region and thus ensure the lubrication of the double bearing 17. Furthermore, the third oil duct can also have a branch formed in the housing part, which branch leads between the first bearing and a second bearing of the input shaft 12, which second bearing is configured as a double bearing 18.
The sealing surface 31 on which the cover 3 rests completely runs around the circumference of the intermediate shaft 5 without interruption. A high level of protection can thus be achieved.
The fan 11 is connected to the input shaft 12 in a rotationally fixed manner in the region of the input shaft 12 that protrudes toward the surroundings. The fan guard 10 surrounds the fan 11 and is detachably connected to the housing part 1.
The air flow delivered by the fan wheel is deflected by the fan guard 10 in such a way that it flows along cooling ribs which are formed on the cover 3 and project toward the environment and extend parallel to the rotational axis of the input shaft.
In this way, improved heat dissipation can be achieved and thus the oil located in the space region can be dissipated.
The spatial region is designed to be as flat as possible, so that almost the entire length of the cover 3 is available for cooling oil.
In particular, the extent of the spatial region in the direction of the axis of rotation of the input shaft is at least ten times greater than the extent in the direction of the axis of rotation of the intermediate shaft 5, in particular the extent in the direction of the axis of rotation of the intermediate shaft 5.
The housing part 1 also has outwardly projecting cooling ribs on its outer surface, so that the heat dissipation of the gear unit is improved.
Furthermore, a cover element covers a cutout of the side wall on at least one side wall of the housing part 1, wherein the cover element also has cooling ribs on its outer surface.
The housing part 1 is preferably manufactured in two parts, namely from a lower part and an upper part placed thereon.
In other exemplary embodiments according to the utility model, instead of the adjusting bearing 6, which is designed as a rolling bearing, in particular as a cylindrical roller bearing, no bearing is provided in the bearing cap 4, but only one through-opening is provided, in particular in order to allow oil to flow from the spatial region to the bearing 2.
