- the invention relates to a transmission with a housing, which has a lower part and a cover part.
- a bearing arrangement of a transmission is known from WO 2017/024646 A1.
- the invention is therefore based on the object of developing a transmission that is as small as possible for a given power and / or the same power.
- the object is achieved in the transmission according to the features specified in claim 1.
- the transmission has a housing which has a lower part and a cover part, in particular a cover part placed on the lower part, and a driving shaft and a driving shaft, the lower part having a first carrier, a second carrier, has a base plate, a bearing receiving part and side walls, each of the side walls being connected on the one hand to the first carrier and on the other hand to the second carrier, in particular being welded, the first carrier being a closed ring structure, in particular a closed ring, the second carrier being an open ring structure, in particular an open ring, is, wherein a first, in particular double, bearing for the rotatable mounting of the driven shaft is received in the base plate, a second bearing for the rotatable mounting of the driven shaft is received in the bearing receiving part, the base plate connected to the second carrier, in particular welded, is wherein the base plate is connected, in particular welded, to the bearing receiving part.
- the advantage here is that a transmission that is as small as possible can be designed for a given output. Because a high torque can be passed through the stiffening by means of the first and second carrier, although the housing can be made compact.
- the bearing of the driven shaft is carried out both in the cover part and in the lower part.
- the second bearing which can be designed as an axial bearing, is also provided.
- an axial force introduced on the load side can be diverted through the second bearing via the load-bearing part to the second carrier and from there via the footplates to a floor of a system within which the transmission is installed.
- the radial bearing can be carried out via the first bearing and the additional bearing accommodated in the cover part.
- the first carrier is spaced apart from the second carrier.
- the advantage here is that the intermediate side walls can be stiffened with ribs in such a way that the first carrier is rigidly connected to the second carrier and a stable housing can thus be provided.
- the axial force introduced can be diverted to the second carrier via the load-bearing part and the second bearing.
- foot plates are connected, in particular welded, to the side of the second carrier facing away from the first carrier.
- the distance between the opening of the open ring structure and the driving shaft is smaller than the distance between the opening and the driving shaft.
- the advantage here is that there is a reduced rigidity in the area of the driving shaft, in particular in the area of the bearing of the driving shaft received in the lower part, so that this area of the transmission is less susceptible to transverse forces from the driving shaft.
- a centering collar is provided on the gearbox for connecting the gearbox to an electric motor, the electric motor can be connected precisely and the introduction of transverse forces can thus be prevented.
- the first carrier is O-shaped and the second carrier is U-shaped.
- the cover part can be placed on the first carrier and can be connected tightly, in particular by means of a flat seal placed on the first carrier.
- the first carrier and the second carrier are each designed to be flat, in particular the plane containing the first carrier being aligned parallel to the plane containing the second carrier.
- the advantage here is that the side walls extend essentially perpendicular to the two planes.
- one or more ribs are connected, in particular welded, to a respective side wall, in particular on the outside of a respective side wall, the respective rib being connected, in particular welded, to both the first carrier and the second carrier.
- the advantage here is that increased rigidity can be achieved.
- the greatest distance on the rib to the respective side wall increases monotonically, in particular strictly monotonically.
- a viewing window is arranged in a recess of at least one of the side walls.
- the cover part is connected to the first carrier, in particular wherein the first carrier is designed circumferentially, i.e. without an opening, and the cover part by means of an edge region of the cover part protruding in the radial direction on the cover part in relation to the axis of rotation of the driven shaft the connection level provided by the first carrier is placed.
- the first carrier can be made widened and thus a support surface for the cover part can be formed.
- a further bearing for the rotatable mounting of the output shaft is received in the cover part.
- the second bearing is an axial bearing, in particular a roller bearing, in particular a spherical roller bearing or a barrel bearing. The advantage here is that high axial forces can be diverted into the second carrier.
- the second carrier has a greater wall thickness than the base plate and than each side wall.
- an oil pan is attached to the side of the base plate facing away from the first carrier.
- the oil pan and the base plate are arranged within the second carrier, in particular within the U, in particular within the legs of the U.
- the advantage here is that the oil pan is arranged in a protected manner.
- second ribs are connected, which are welded to the base plate and are also welded to the second carrier.
- the oil pan has welded third ribs on its bottom area facing the cover part, which are fastened, in particular welded, to a circumferential edge area of the oil pan, the direction of extent of the third ribs, in particular the direction of the longest extent of the third ribs , is arranged in a plane whose normal direction is parallel to the axis of rotation of the output shaft and is oriented at an angle to the plane which contains at least axes of rotation of at least two shafts of the transmission, the angle being a value between 10 ° and 80 ° .
- the advantage here is that on the one hand the oil pan is stiffened and on the other hand the oil foam is calmed and broken down with oil. Further advantages result from the subclaims.
- FIG. 1 the housing of a transmission according to the invention with a split housing is shown in an oblique view with the cover part 1 lifted off.
- FIG. 2 the transmission is shown from a different perspective in an oblique view, so that an oil pan 20 is visible, which is arranged on the underside of the lower part.
- the transmission is shown in an oblique view from a third angle.
- FIG. 4 the oil pan 20 is shown in an oblique view.
- FIG. 5 shows a cross section through a region of the transmission.
- the housing of the transmission has a cover part 1 which is placed on a lower part of the housing in the axial direction, that is, parallel to the direction of the axis of rotation of the output shaft 21 of the transmission.
- the lower part has a bearing seat for a first bearing 50 of the output shaft 21 and a further bearing seat for a second bearing 51 of the output shaft 21.
- the cover part 1 also has a bearing seat for a bearing of the output shaft 21.
- the output shaft 21 is acted upon by an axial force when the transmission is in operation.
- the second bearing 51 is therefore designed as an angular contact bearing, in particular a barrel bearing.
- the axial force introduced on the driven shaft 21, in particular by a driven load is transferred to the bearing receptacle.
- This bearing receptacle is implemented by means of a bearing seat that is formed on a bearing receptacle part 55 and finely machined.
- the second bearing 51 is therefore in the bearing receiving part 55 recorded, which is welded to the base plate and is connected to the base plate 7 on the side facing away from the cover part 1.
- the first bearing 50 is received in the base plate 7.
- a bearing seat is formed on the base plate 7, in particular finely machined.
- the second carrier 5 is welded to the base plate 7 of the lower part.
- the transmission is preferably oriented such that the axis of rotation of the output shaft 21 is oriented vertically.
- the second carrier 5 is U-shaped. It is therefore not completely circumferential on the edge of the base plate 7.
- the opening of the U-shape is directed towards the driving shaft.
- the opening of the U-shape is closer to the driving shaft 22 than to the driven shaft 21.
- the U-shape is flat.
- the normal of the plane containing the U-shape is aligned parallel to the axis of rotation of the output shaft 21.
- the second carrier 5 is welded to the base plate 7 and thus gives it a high degree of rigidity and / or stability.
- a first carrier 2 is O-shaped, in particular ring-shaped.
- the normal of the plane containing the O-shape is aligned parallel to the axis of rotation of the output shaft 21.
- the first carrier 2 and the second carrier 5 are therefore each designed to be flat and aligned parallel to one another.
- the first carrier 2 is welded to the side walls 3, the side walls 3 are welded to the second carrier 5 and the second carrier 5 is welded to the base plate 7.
- the lower part of the transmission is formed in this way.
- the four side walls 3 each have a thinner wall thickness than the base plate 7 and than the first carrier 2 and than the second carrier 5.
- first ribs 4 are arranged on the lower part to increase the rigidity and stability.
- the first ribs 4 are preferably designed in such a way that each of the first ribs 4 is connected to both the first carrier 2 and also to the second carrier 5 and to one of the side walls 3, in particular is welded.
- first carrier 2 and the second carrier 5 protrude towards the surroundings on the respective side wall 3, so that the respective first rib 4 can be attached to the outside of the side wall 3.
- the first ribs 4 are spaced from one another.
- 4 pockets are formed between the first ribs, which are delimited by the first carrier 2, by the second carrier 5, by the respective side wall 3 and by two first ribs 4 in each case.
- the foot plates 6 are connected, in particular welded, to the side facing away from the side walls 3, in particular the underside, of the second carrier 5.
- the second bearing 51 received in the bearing receiving part 55 transmits the axial force entered by the output shaft 21 via the bearing receiving part 55 to the base plate 7 and from there to the second carrier 5 and from there to the base plates 6, which are on the floor of a system or on a mounting surface of a machine are arranged.
- a portion of the transverse forces applied to the driven shaft 21 is diverted to the base plate 7 via the first bearing 50.
- the opening of the U of the second carrier 5 is further away from the second bearing 51 than the yoke of the U which connects the two legs of the U. In this way, the entry of the axial force is carried out at the stiffest point of the U.
- an oil pan 20 is attached, in which the oil sump of the transmission can be accommodated. This oil pan 20 is pressed against the base plate 7 by means of screws, in particular by means of screw heads of the screws.
- Both the oil pan 20 and / or the base plate 7 are arranged within the U, in particular within the legs of the U.
- the respective first rib 4 has a maximum distance, which increases monotonically with increasing distance from the first carrier 2, from that side wall 3 to which it is connected, in particular welded. In this way, the second carrier 5 is connected to the side wall 3 with improved rigidity.
- the first carrier 2 is circumferential, that is to say without an opening.
- the cover part 1 in particular by means of an edge region of the cover part 1 that protrudes on the cover part 1 in relation to the axis of rotation of the driven shaft in the radial direction on the cover part 1, is placed on the connection plane provided by the first carrier 2 and is tightly connected by means of an intermediate flat seal in that the cover part 1 is pressed against the first carrier 2 by screws screwed through the cover part 1 and into threaded bores of the first carrier 2, in particular their screw heads.
- a radial bore 54 made in the base plate 7 opens into the axial bore 53 and thus also enables oil to be led out, this axial bore 53 being closed during operation, in particular with a sealing plug.
- second ribs 23 are connected, which are welded to the base plate 7 and are also welded to the second carrier 5. The rigidity of the lower part is thus further increased.
- the second carrier 5 is thus stiffened on its side facing the cover part 1 and on its side facing the oil pan 20 by means of the first and second ribs (4, 23).
- the weight of an oil pan 20 filled with oil together with the weight of the base plate 7, together with the forces derived into the base plate 7 and the force flows supplied via the side walls 3, can be fed to the second carrier 5 without significant deformations of the lower part occurring.
- the oil pan 20 itself has on its bottom region 42 facing the cover part 1 welded third ribs 41 which are welded on a circumferential edge region 40 of the oil pan. These third ribs 41 serve to calm the oil collected in the oil pan 20.
- the direction of extent of the third ribs 41 in particular the direction of the longest extent of the third ribs 41, is arranged in a plane whose normal direction is aligned parallel to the axis of rotation of the driven shaft and is oriented at an angle to that plane which has at least two axes of rotation Contains shafts of the transmission, the angle being a value between 10 ° and 80 °.
- the ribs 41 therefore do not extend perpendicular, but rather obliquely to the plane containing the axes of rotation of the at least two shafts.
- a viewing window is arranged in a recess in the side wall 3 of the lower part.
