Description

[0001] The invention relates to a geared motor.

[0002] From US 2 596 794 A a transmission is known which can be driven by an electric motor by means of a clutch.

[0003] A general-purpose transmission with a motor is known from US 3 029 661 A.

[0004] From DE 10 2009 017 017 A1 an arrangement with heavy plates for a supporting structure is known.

[0005] A drive and a fan are known from DE 10 2005 031 197 A1.

[0006] From DE 10 2011 012 641 A1 a drive device with holding means, in particular a motor swing arm or foundation frame, and a use of a motor swing arm are known.

[0007] The invention is therefore based on the object of developing a geared motor, whereby environmental protection and operational safety are to be improved.

[0008] According to the invention, the object is achieved in the geared motor according to the features specified in claim 1.

[0009] The axis of rotation of the motor’s rotor shaft, i.e. the rotor shaft axis direction, defines the axial direction.

[0010] The advantage is that the geared motor with the motor support unit can be designed safely and compactly. The motor support unit is suitable for bevel gear units and spur gear units, as it can be attached to any side surface of the gear housing.

[0011] The material requirements for the engine support unit are significantly lower than in the prior art, as the engine support unit only supports the engine and braces it against the transmission. This improves environmental protection.

[0012] Motors of various sizes can be connected to the gearbox housing using the motor support unit. Motors with a footplate that connects to the base of the motor support unit are advantageous. This allows for heavier motors to be mounted than, for example, with a flange connection between the motor and the gearbox housing, since the load-bearing capacity of the motor support unit is greater than that of a flange.

[0013] In an advantageous embodiment, the motor support unit at least partially surrounds a coupling, in particular a fluid coupling, arranged between the transmission and the motor, forming a housing. Advantageously, the coupling connects the input shaft of the transmission and the rotor shaft of the motor in a rotationally fixed manner. The coupling rotates at least partially with the rotor shaft and / or the input shaft.

[0014] The engine support unit at least partially encloses the clutch and thus the rotating parts of the clutch. This eliminates the need for an additional clutch housing, thereby improving environmental protection.

[0015] In an advantageous embodiment, the motor support unit comprises at least one housing part. The advantage here is that the housing part can be made lighter and thinner than the side parts or the connecting part. This improves environmental protection because material can be saved.

[0016] In an advantageous embodiment, the connecting part has a recess through which an input shaft of the gear unit is passed, in particular, wherein the coupling can be passed through the recess. This advantageously allows the geared motor to be designed compactly. The ability to pass the coupling through the recess enables simplified assembly, since the coupling is first mounted on the input shaft and then the motor support unit is guided over the coupling and partially over the input shaft. This simplifies the assembly of the coupling compared to the reverse assembly sequence.

[0017] In an advantageous embodiment, the connecting part is designed in one piece, in particular in one part, and has two spaced-apart leg sections and a base section connecting the leg sections, wherein the two respective free ends of the leg sections are connected to one another by means of a yoke part, in particular wherein each leg section is welded to the yoke part, wherein the gear housing has a cover part, in particular a bearing cover part, which is tightly connected, in particular oil-tight and / or airtight, to the gear housing part, wherein the leg sections touch the gear housing part and the contact surfaces of the leg sections with the gear housing part span a plane whose normal vector is parallel to the axial direction,The cover part extends into this plane between the leg sections and / or the axially overlapping area of ​​the cover part at least partially overlaps the axially overlapping area of ​​the plane, the axial projection of the cover part being completely overlapped by the axial projection of the yoke part in at least one direction transverse to the axial direction. This advantageously allows the geared motor to be designed compactly. The connecting part surrounds the input shaft of the gear unit and can be connected to the gear housing part by means of at least four connecting means, in particular screw parts, that can be arranged uniformly in the circumferential direction of the connecting part. The connecting part contacts the housing part. The load-bearing capacity of the connecting part is advantageously improved by means of the yoke part.

[0018] In an advantageous embodiment, the yoke part extends further toward the motor in the axial direction than the cover part. This is advantageous because the cover part can be bridged by the yoke part. The connecting part contacts the transmission housing part. Advantageously, the contact surface of the connecting part with the transmission housing part is further away from the motor than the cover part.

[0019] In an advantageous embodiment, the yoke part is designed such that it bridges the cover part. This advantageously allows the two free ends of the leg sections to be connected by means of the yoke part, thus improving the load-bearing capacity of the connecting part.

[0020] In an advantageous embodiment, the yoke part is arranged on a side surface of the connecting part, in particular the leg sections, facing away from the transmission. This is advantageous in that the yoke part can be easily connected, in particular welded, to the connecting part. The yoke part can be spaced apart from the contact surface of the connecting part with the transmission housing part.

[0021] In an advantageous embodiment, the yoke part is designed as a bent part. This is advantageous because the yoke part can be used to bridge various contours of the cover part. This allows for a bent part to be manufactured easily.

[0022] In an advantageous embodiment, the base part has motor support surfaces facing the motor, which are flat and contact the motor, in particular the base part of the motor, in particular of the assembled motor, wherein the motor support surfaces span a common plane whose normal vector is substantially perpendicular to the rotor shaft axis of the motor, wherein the connecting part has alignment surfaces facing the gearbox housing part, which are flat and contact the gearbox housing, wherein the alignment surfaces span a common plane whose normal vector is substantially parallel to the rotor shaft axis of the motor. The advantage here is that the motor can be aligned to the input shaft of the gearbox by means of the motor support surfaces. The motor support surfaces can be easily adapted to the shaft geometry by means of grinding and / or milling.In addition, sheet metal parts can be inserted between the motor support surfaces and the base part to increase the distance between the base part and the floor part and / or to align the motor relative to the gearbox.

[0023] In an advantageous embodiment, the engine support unit has at least one side part, which is connected, in particular welded, to the connecting part and the base part, wherein the side part has a first bracing section extending from the connecting part to the base part. The advantage here is that the torsional rigidity and thus the load-bearing capacity of the engine support unit are improved by means of the side part. The side part with the bracing section has a lower mass than a solid side part.

[0024] In an advantageous embodiment, the first bracing section forms an angle of 30° to 60°, in particular 40° to 50°, with the normal vector of the plane of the motor support surfaces. In particular, the first bracing section forms an angle of 30° to 60°, in particular 40° to 50°, with the normal vector of the plane of the alignment surfaces. This is advantageous in that the motor support unit is compact and lightweight.

[0025] In an advantageous embodiment, the side part has a second bracing section that connects the first bracing section to the connecting part, wherein the first bracing section is connected to the second bracing section at an axial distance from the connecting part, in particular wherein the second bracing section extends in the axial direction from the connecting part to the first bracing section and is firmly connected to the base part. The advantage here is that the load of the motor can be distributed over the surface of the side part, thus the connection between the connecting part and the base part can be relieved by means of the side parts. The load-bearing capacity of the motor support unit is thus also improved.

[0026] In an advantageous embodiment, at least one recess in the engine support unit is bordered by the first bracing section, the second bracing section, and the connecting part. This advantageously reduces the mass of the engine support unit. This saves material and improves environmental protection.

[0027] In an advantageous embodiment, a respective cover part covers the respective recess. Advantageously, the coupling arranged within the motor support unit is enclosed in a housing formed by the motor support unit, the cover part, the motor, and the gear housing. This improves the operational reliability of the geared motor, as the coupling is protected from foreign objects that could be trapped by the rotating parts of the coupling.

[0028] In an advantageous embodiment, a through bore is formed in at least one alignment surface, wherein the alignment surfaces project from and / or are raised from the connecting part, in particular wherein the alignment surfaces are formed integrally with the connecting part. Advantageously, the motor can be aligned relative to the input shaft of the gear unit by means of the alignment surfaces. The alignment surfaces can be easily adapted to the shaft geometry of the gear motor by means of grinding and / or milling.

[0029] In an advantageous embodiment, a plate part is connected, in particular welded, to the connecting part as the respective alignment surface. This is advantageous because the engine support unit can be assembled from stamped and / or flame-cut parts, with the stamped and / or flame-cut parts being weldable. This allows the engine support unit to be manufactured cost-effectively.

[0030] According to the invention, the motor support unit comprises a pan, in particular an oil pan. This is advantageous in that the fluid arranged in a fluid coupling for coupling the shafts can be drained into the pan. This allows the shafts to be decoupled in an emergency by draining the fluid from the fluid coupling. The operational reliability of the geared motor is thus improved. Environmental protection is also improved because the fluid can be collected by the oil pan and thus does not escape uncontrolled into the environment.

[0031] In an advantageous embodiment, the pan has an oil drain, in particular a hole for the oil drain is provided in the base part. This is advantageous because the pan can be drained in a controlled manner. Advantageously, the pan can be drained with the engine installed.

[0032] According to the invention, the base part is designed as a bent part and functions as the bottom of the pan, with a bent section of the base part functioning as at least part of the pan wall. This is advantageous because a single part serves as the bottom of the engine support unit and pan, which can be constructed in one piece and thus free of predetermined breaking points. This saves on components and improves environmental protection.

[0033] In an advantageous embodiment, the connecting piece and two side pieces each function as an additional part of the tub wall. The advantage here is that the tub can be integrated into the engine support unit. This saves on components and improves environmental protection.

[0034] In an advantageous embodiment, the at least one housing part is connected, in particular detachably connected, to at least one side part of the motor support unit. Advantageously, the coupling, in particular the rotating parts of the coupling, can be enclosed by the motor support unit and the housing part, forming a housing. The housing part is removable, allowing for easy maintenance or replacement of the motor.

[0035] In an advantageous embodiment, the at least one side part is connected, in particular firmly connected, in particular riveted and / or welded, to at least one fastening part for fastening the housing part. It is advantageous that the side parts can be manufactured from simple plate parts. The thickness of the plate can be increased by means of the fastening parts, so that the housing part can be arranged perpendicular to the side parts.

[0036] In an advantageous embodiment, the housing part is designed as a sheet metal part, particularly a perforated sheet metal part. This is advantageous because a fan impeller can be integrated into the motor support unit, which redirects outside air, i.e., air from outside the motor support unit, to the motor. This improves motor cooling and increases the operational reliability of the geared motor.

[0037] In an advantageous embodiment, the housing part extends from one of the side parts to the other side part and / or is arranged between the side parts. This advantageously protects the clutch arranged in the motor support unit from foreign objects that could become trapped between the rotating parts of the clutch.

[0038] In an advantageous embodiment, a web connects the two side parts of the motor support unit to one another, in particular, wherein the web connects two respective first bracing sections of the side parts, in particular, wherein the web extends transversely to the rotor axis direction from one side part to the other side part, in particular, wherein the web is arranged on a side surface of the side part facing the respective other side part. This is advantageous in that the torsional rigidity of the motor support unit is improved.

[0039] In an advantageous embodiment, at least one through-bore is formed in at least one motor support surface, in particular extending through the base part. The motor support surfaces project from and / or are raised from the base part, in particular the motor support surfaces are formed integrally with the base part, in particular by being designed as finely machined thickened portions of the base part. Advantageously, the motor can be aligned with the input shaft of the transmission by means of the motor support surfaces.

[0040] In an advantageous embodiment, a plate part is connected, in particular welded, to the base part as the respective motor support surface. This is advantageous because the base part can be manufactured as a stamped and bent part, whereby shape tolerances can be easily compensated for using the plate parts.

[0041] In an advantageous embodiment, a fan wheel is arranged between the motor and the gearbox, in particular, the fan wheel being non-rotatably connected to the input shaft of the gearbox and / or to the rotor shaft of the motor. This advantageously allows the geared motor to be designed compactly. This eliminates the need for an additional fan housing. This reduces the number of components and improves environmental protection.

[0042] In an advantageous embodiment, a torque support part is connected to the transmission housing, wherein the torque support part is spaced apart from the motor support unit, in particular wherein the torque support part is suitable for transmitting torque from the transmission housing to a foundation. Advantageously, the motor and the motor support unit are decoupled from the torque support. This makes the motor support unit lighter, thus saving material and improving environmental protection.

[0043] Further advantages arise from the subclaims.

[0044] The invention will now be explained in more detail with the aid of illustrations: In the Fig. 1 shows an oblique view of a geared motor with a motor support unit according to the invention. Fig. 2 shows the gear motor according to the invention with the motor support unit in a partially exploded oblique view. In Fig. Figure 3 shows an exploded view of the gear motor according to the invention. In Fig. 4 shows the engine support unit in an oblique view. Fig. 5 shows the engine support unit in another oblique view.

[0045] The Fig. The geared motor shown in Figure 1 comprises a gearbox with a gearbox housing 1, a motor 6, and a motor support unit. The motor 6 is connected to a gearbox housing part of the gearbox housing 1 by means of the motor support unit.

[0046] In the Fig. In the embodiment shown in Figures 1 to 3, the transmission is designed as a spur gear transmission, so that the input shaft 33 is arranged parallel to the output shaft and the shafts of the gear stages, i.e. intermediate shafts, in particular wherein the shaft axes are parallel.

[0047] The transmission housing 1 comprises at least one transmission housing part and at least one cover part (3, 23, 29). The cover part (3, 23, 29) functions as a bearing cover part. A bore in the transmission housing part for accommodating a bearing for supporting a shaft can thus be closed, in particular tightly closed, by means of the cover part (3, 23, 29). Preferably, several bores can be closed by means of a single first cover part 29.

[0048] In the Fig. 2 and Fig. A bearing for supporting an input shaft 33 of the transmission is arranged in the first cover part 29 shown in Figure 3. A non-contact seal, in particular a labyrinth seal and / or gap seal, seals the input shaft 33 from the first cover part 29. A grease line 17 is arranged on the first cover part 29 for the seal. Lubricant can be supplied to the seal via the grease line 17. The grease line 17 has an inlet opening arranged outside the spatial area of ​​the motor support unit. The first cover part 29 is arranged at least partially in the spatial area of ​​the motor support unit.

[0049] The motor support unit comprises a housing part 4 and two cover parts (11, 22). The housing part 4 and the cover parts (11, 22) are each detachably connected to the motor support unit, in particular by screwing. The motor support unit, together with the housing part 4 and the cover parts (11, 22), at least partially forms the housing for a coupling 25, which connects the input shaft 33 of the gearbox to the rotor shaft 30 of the motor 6. The housing part 4 and the cover parts (11, 22) are each designed as sheet metal parts, preferably made of perforated sheet metal.

[0050] The coupling 25 has rotating parts that are non-rotatably connected to the rotor shaft 30 and / or the input shaft 33 of the gearbox, thus rotating with the respective shaft. The maximum diameter of the coupling 25 is larger than the outer diameter of the input shaft 33 and larger than the diameter of the rotor shaft 30. The rotating parts of the coupling 25 are thus at least partially enclosed by the motor support unit, forming a housing.

[0051] The transmission housing 1 has bores that function as inspection openings. For example, a sensor (not shown), in particular a temperature sensor or oil level sensor, can be inserted into the transmission housing 1 through the bores. The bores can be closed and / or sealed using screw plugs (2, 24).

[0052] On the application side, the gearbox has at least one flange part 19. The output shaft of the gearbox (not shown) is arranged radially within the flange part 19. An application to be driven can be connected to the flange part 19.

[0053] A torque support part 12 is detachably connected to the transmission housing 1. The torque support part 12 has a bore for connecting a torque support to the torque support part 12. The torque support part 12 is screw-connected to the transmission housing 1 by means of two intermediate plate parts (13, 14). The motor support unit with the motor 6 is arranged at a distance from the torque support part 12. Preferably, the motor support unit is arranged on a different side surface of the transmission housing 1 than the torque support part 12.

[0054] The Fig. 4 and Fig.The engine support unit shown in detail in Figure 5 comprises a base part 7, a connecting part 15, two side parts (5, 10), and a web 28. These parts are firmly connected to one another, in particular welded. Preferably, the base part 7, the connecting part 15, the side parts (5, 10), and / or the web 28 are designed as stamped and / or flame-cut parts, in particular as stamped and bent parts.

[0055] The connecting part 15 touches the transmission housing part. It has bores (34, 35) and is detachably connected, in particular screw-connected, to the transmission housing part by means of connecting means (16, 18) that can be passed through the bores (34, 35). At least one alignment surface 50 is arranged on the side of the connecting part 15 facing the transmission housing 1. The bore 34 extends through the alignment surface 50. The alignment surface 50 protrudes from the connecting part 15, in particular with the side surface of the connecting part 15 facing the transmission housing 1 being substantially flat. The alignment surface 50 is preferably designed as a plate part that is firmly connected, in particular welded, to the connecting part 15. Alternatively, the alignment surface 50 is designed as a single piece with the connecting part 15.

[0056] The alignment surface 50 is thus designed as a flat surface section of the connecting part 15, which is designed such that the connecting part 15 can be aligned relative to the transmission housing part. The alignment surface 50 contacts the transmission housing part when the motor support unit is connected to the transmission housing part.

[0057] The alignment surface 50 protrudes from the connecting part 15 at least far enough that the transmission housing part connected to the motor support unit only touches the alignment surface 50 or the alignment surfaces 50. Preferably, a plurality of alignment surfaces 50 are arranged evenly distributed in the circumferential direction of the connecting part 15. The surfaces of the alignment surfaces 50 facing the transmission housing part are arranged in a common plane. In particular, the alignment surfaces 50 are machined by grinding and / or milling such that the surfaces of the alignment surfaces 50 facing the transmission housing part are arranged in a common plane.

[0058] The connecting part 15 has a recess through which the input shaft 33 of the transmission can be passed. The recess is preferably designed such that a coupling 25 arranged on the input shaft 33 can be passed through the recess. The first cover part 29 preferably projects into the recess. The recess is therefore larger than the first cover part 29. Thus, the connecting part 15 at least partially surrounds the first cover part 29.

[0059] Preferably, the connecting part 15 is designed as a single piece in a U-shape with two spaced-apart leg sections and a base section connecting the leg sections. A yoke part 20 connects the two free leg ends of the connecting part 15. The yoke part 20 is arranged on the side facing away from the transmission housing 1 and is firmly connected, in particular welded, to the connecting part 15. Preferably, the yoke part 20 is designed as a bent part, wherein the yoke part 20 has a curvature. This curvature is designed such that the curvature extends further in the axial direction toward the motor 6 than the connecting part 15.

[0060] The yoke part 20 is preferably designed such that a cover part 23 projecting into the axial space area of ​​the connecting part 15, in particular between the leg sections of the connecting part 15, is spanned and / or bridged by the yoke part 20.

[0061] The leg sections thus touch the gear housing part. The contact surfaces of the leg sections with the gear housing part span a plane whose normal vector is parallel to the axial direction. The cover part 23 protrudes between the leg sections into this plane, with the axially overlapped area of ​​the cover part 23 at least partially overlapping the axially overlapped area of ​​the plane. The axial projection of the cover part 23 is completely overlapped by the axial projection of the yoke part 20 in at least one direction transverse to the axial direction.

[0062] An axial projection is defined here as an orthogonal projection, where the normal of each image point to the projection plane is parallel to the axial direction.

[0063] The cover part 23 functions as a bearing cover part for a bearing accommodating an intermediate shaft. The intermediate shaft is arranged parallel to the input shaft 33 of the transmission and spaced apart from the input shaft 33.

[0064] The side parts (5, 10) each have a first bracing section extending from the connecting part (15) to the base part (7). Preferably, the first bracing section forms an angle of 30° to 60°, in particular 40° to 50°, with the normal vector of the plane of the base part (7). The first bracing section forms an angle of 30° to 60°, in particular 40° to 50°, with the normal vector of the plane of the connecting part (15).

[0065] Preferably, the first bracing section is designed at an angle. A first section of each first bracing section extends axially from the connecting part 15. A second section of each first bracing section is arranged at an angle of 30° to 60°, in particular 40° to 50°, to the first section and connects the first section to the base plate 7.

[0066] Preferably, each side part (5, 10) has a second bracing section that extends axially from the connecting part 15 to the first bracing section. The first bracing section is thus connected to the second bracing section at an axial distance from the connecting part 15. The second bracing section is firmly connected to the base part 7 and delimits the base part 7 in the transverse direction. The base part 7 is thus arranged between the two side parts (5, 10). Each side part (5, 10) is thus substantially V-shaped.

[0067] The engine support unit thus has at least one recess which is bordered by the respective first strut section, the respective second strut section and the connecting part 15. The recess is covered by one of the cover parts (11, 22).

[0068] The web 28 connects the two side parts (5, 10) transversely to the rotor shaft axis. Preferably, the web 28 is arranged in the transition area between the first and second sections of the respective first bracing section. The web 28 thus extends transversely from one side part 5 to the other side part 10. The web 28 is spaced apart from the base plate 7.

[0069] The side parts (5, 10) have holes 40 for detachably connecting the cover parts (11, 22) to the side parts (5, 10). The holes 40 are designed as continuous threaded holes. Thus, screw parts that can be passed through holes in the cover parts (11, 22) can be screwed to the side parts (5, 10).

[0070] The side parts (5, 10) have fastening parts 21 for detachably connecting the housing part 4 to the side parts (5, 10). The fastening parts 21 are arranged on the mutually facing side surfaces of the side parts (5, 10). They are essentially cuboid-shaped and firmly connected to the side parts (5, 10), preferably welded and / or riveted. The fastening parts 21 each have a threaded hole. Thus, screw parts that can be passed through holes in the housing part 4 can be screwed to the fastening parts 21. The housing part 4 and the side parts (5, 10) enclose a non-zero angle, which is preferably between 70° and 110°, in particular a right angle.

[0071] Preferably, the housing part 4 has a bend, i.e., it is angled. The assembled housing part 4 extends axially parallel to the angled first bracing sections of the side parts (5, 10). In the transverse direction, the housing part connects the side parts (5, 10).

[0072] Thus, the clutch 25 is surrounded by the motor support unit with the housing part 4, the cover parts (11, 22), the gear housing 1 and the motor 6.

[0073] The base part 7 is designed as a bent part. It has two sections: a pan section 26 and a motor mounting section 42. Preferably, the pan section 26 is arranged further down in the direction of gravity than the motor mounting section 42. For this purpose, the base part 7 has a rounded, step-like transition area between the pan section 26 and the motor mounting section 42. The transition area functions as at least part of the pan wall 51. The pan section 26 has a bore that functions as an oil drain 27. A valve is preferably arranged in the bore.

[0074] The pan section 26 functions as the pan bottom and at least partially as the pan wall of a pan, in particular an oil pan. The pan is delimited laterally by the side parts (5, 10) and the connecting part 15, which function as the pan wall.

[0075] The clutch 25 has a fusible link (not shown). The solder core of the fusible link melts when the clutch 25 overheats, causing the clutch fluid to escape from the clutch 25 and be collected in the sump.

[0076] The motor mounting section 42 has a first motor support surface 8 and a second motor support surface 31. The motor support surfaces (8, 31) protrude from the motor mounting section 42. They are formed integrally with the base part 7 or are firmly connected to the base part 7, preferably by welding. The motor support surfaces (8, 31) are preferably designed as plate parts.

[0077] The motor support surfaces (8, 31) are machined by grinding and / or milling such that the motor support surfaces (8, 31) that contact the mounted motor 6, in particular the base part 41 for securing the motor 6 to the floor, i.e., the contact areas of the motor 6 with the base part 7, are arranged in a common plane. The normal vector of this plane is preferably oriented perpendicular to the normal vector of the plane of the connecting surfaces.

[0078] At least one bore 32 is formed in the first motor support surface 8, which extends through the base part 7. At least one bore 43 is formed in the second motor support surface 31, which extends through the base part 7. By means of connecting means 9, in particular screw parts, which can be passed through the bores (32, 43), the base part 41 of the motor 6 can be connected to the base part 7 of the motor support unit.

[0079] In a further embodiment, a fan impeller (not shown) is arranged in the motor support unit. The fan impeller is rotationally fixedly connected to the input shaft 33 of the gearbox and / or the rotor shaft 30 of the motor 6. The fan impeller is arranged between the clutch 25 and the gearbox housing 1 or between the clutch 25 and the motor 6.

[0080] In a further embodiment, a brake (not shown) is arranged in the motor support unit.

[0081] In further embodiments not shown, the transmission is designed as an angular transmission or epicyclic transmission, in particular a planetary transmission.

[0082] In a further embodiment, centering pins (not shown) are provided between the transmission housing part and the connecting part 15. These centering pins can be inserted into bores in the alignment surfaces 50 and in the transmission housing part for positioning the engine rocker relative to the transmission housing 1.
