Description

[0001] The present invention relates to a transport and handling device for a transmission part according to claim 1. The transport and handling device is particularly designed to secure a transmission part for transport and handling purposes and to protect sensitive functional surfaces of the transmission part from environmental influences, in particular mechanical impacts. The invention further relates to a method for transporting and handling transmission parts according to claim 8.

[0002] Such transport devices typically have a volume with walls to accommodate the transmission components. The transmission components can strike a wall(s) within this volume when subjected to accelerations acting on the transport device, resulting in damage.

[0003] From JP 2011 016 586 A a transport container for workpieces is known in which the workpieces are fixed inside the transport container to protect them from damage during transport.

[0004] DE 19 508 500 A1 discloses a transport packaging for machine parts. Each machine part is mounted on its own frame and provided with its own self-supporting and stackable cover, allowing even bulky machine parts, such as motor vehicles' engines and transmissions, to be transported in bundles.

[0005] From DE 6 806 220 U, a multi-part drum-shaped packaging container intended for yarn carriers is already known, with a tubular drum shell enclosing the packaged goods on the outside, which can be closed at both ends by a cover designed as a cover with a recessed base and lid and drawn axially into the drum shell.

[0006] The object of the invention is to provide a device for transporting and handling transmission parts which enables reliable, damage-free transport and safe handling of transmission parts with simple design measures.

[0007] A further object of the invention is to provide a method for transporting and handling transmission parts. The method according to the invention is intended to minimize the risk of damage to transmission parts during transport or handling, particularly to their functional surfaces.

[0008] This object is achieved by a transport and handling device having the features of claim 1. The subclaims form advantageous developments of the disclosure.

[0009] Subject matter of the subclaims can be combined with one another in a technologically useful manner. Features of the entire disclosure can be combined with one another in a technologically useful manner.

[0010] The description, particularly in connection with the figures, further characterizes and specifies the disclosure.

[0011] The object is further achieved by a method according to the invention according to claim 8.

[0012] Accordingly, a transport and handling device is provided for a gear part having functional surfaces, wherein the transport and handling device comprises at least one wall, wherein the transport and handling device comprises at least one clamping device, in particular a tie rod, wherein the gear part can be clamped by means of the clamping device, in particular a tie rod, such that the gear part and preferably the functional surfaces of the gear part are arranged at a distance from the at least one wall, in particular when accelerations act on the transport and handling device.

[0013] The wall(s) is / are present and configured to provide at least partial shielding from the transmission part to protect the transmission part or functional surfaces of the transmission part from damage. The wall(s) can be one or more inner walls and / or one or more outer walls. A wall(s) can be continuous, i.e., uninterrupted. A wall(s) can have one or more interruptions.

[0014] In the sense of the invention, bracing can be understood as fixing or fastening.

[0015] The invention can be understood, described and represented in such a way that a gear part can be clamped or fixed or fastened by means of the clamping device, in particular tension rods in the transport and handling device, for example in the sense of within the transport and handling device or in a volume of the transport and handling device, and / or on or with or on the transport and handling device.

[0016] It is preferably provided that the gear part can be clamped in the transport and handling device or in a volume of the transport and handling device by means of the clamping device, in particular tension rods, in such a way that the gear part, preferably functional surfaces of the gear part, is or are arranged at a distance from the at least one wall, in particular when accelerations act on the transport and handling device.

[0017] Within the meaning of the invention, a functional surface of a transmission part can be a toothing. Within the meaning of the invention, tooth-free surfaces of a transmission part can also be functional surfaces of the transmission part.

[0018] Within the scope of the invention, a transmission part can be a gear. In particular, a transmission part can be a planetary gear, a sun gear, or a ring gear carrier. Furthermore, it is possible for a transmission part to be a combination of identical or different transmission parts. Within the scope of the invention, a transmission part can also be made up of multiple parts.

[0019] Handling within the meaning of the invention can take place at least by inserting and removing the gear part from the transport and handling device. Furthermore, handling can be seen in the fact that the gear part can be moved or is movable at least close to a processing device without the gear part itself or functional surfaces having to be touched.

[0020] For this purpose, the transport and handling device has a clamping device, in particular a tension rod, with which a gear part, for example a gear wheel, can be moved or is movable before or after transport.

[0021] Gearbox components, especially functional surfaces of gearbox components, are sensitive to environmental influences, especially mechanical impacts. Accordingly, the invention provides for shielding the functional surfaces or the gearbox component from mechanical influences by at least one wall or walls.

[0022] An orientation of the wall or walls relative to the gear part can result, for example, from a position of the gear part or the functional surfaces on the gear part.

[0023] For example, a gear part designed as a sun gear has functional surfaces on its inner and outer circumference. A radially inner peripheral functional surface can serve to accommodate a shaft-hub connection. A radially outer peripheral functional surface can be defined by a toothing. The gear part is planar in sections on an axial base and cover surface. Axial base and / or cover surface(s) can also comprise, have or be designed as functional surface(s). The gear part designed as a sun gear is clamped axially in the transport and handling device at the base and cover surface so that functional surfaces, in particular radially outer peripheral functional surfaces, do not necessarily have to be touched.

[0024] A gear component designed as a planetary gear also has functional surfaces on its inner and outer circumference. An inner functional surface can accommodate a rotary bearing, such as a rolling bearing. A radial outer functional surface can be defined by a toothing that meshes with the toothing on the sun gear.

[0025] Analogous to the sun gear, the gear component designed as a planetary gear is partially planar on an axial base and / or cover surface. Axial base and / or cover surface(s) can also include, have, or be designed as functional surfaces. The gear component designed as a planetary gear is clamped axially in the transport and handling device at the base and / or cover surface, so that functional surfaces do not necessarily have to be in contact.

[0026] Overall, the combination of clamping device and wall(s) represents a simple constructive option for providing a transport and handling device for the safe transport and handling of gear components, with which damage to the gear component or functional surfaces can be avoided.

[0027] According to the invention, the at least one wall is provided as a cylindrical wall on a centering mandrel, which can be penetrated essentially centrally by the at least one clamping device, in particular a tie rod. The centering mandrel fixes the transmission part primarily in the radial direction. This prevents damage to the transmission part during transport and handling.

[0028] Preferably, the centering mandrel is shorter than the gear part when viewed in an axial direction.

[0029] It's also possible that the centering pin is longer than the gear component in an axial direction. This can provide additional axial fixation of the gear component and thus offer a way to prevent damage to the gear component.

[0030] It may also be possible for the centering pin to be substantially the same length in an axial direction as the gear component in the axial direction. Thus, the centering pin can alternatively or additionally fix or limit the gear component in the axial direction.

[0031] The centering pin is preferably made of plastic or comprises at least one plastic. If the transmission part is made of a metallic material or comprises at least one metallic material, such a centering pin can prevent damage when the transmission part comes into contact with the centering pin, since the centering pin is flexible relative to the metallic functional surface on the transmission part.

[0032] The centering mandrel can also have means for centering a preferably bell-shaped cover for covering a transmission part or for covering functional surfaces of a transmission part, which can be formed at least from a sleeve and a cover plate.

[0033] The cover may provide a volume of the transport and handling device.

[0034] The cover can be considered a sleeve or can include a sleeve.

[0035] In a further embodiment, it can be provided that the at least one clamping device, in particular tension rod, has at least one threaded bolt and at least one threaded sleeve that can be screwed to the threaded bolt, wherein the at least one threaded bolt is connected to the centering mandrel, wherein the at least one threaded sleeve extends through a cover plate and wherein the at least one threaded sleeve rests positively on a cover plate, in particular with a circumferential collar.

[0036] The threaded bolt is connected to the centering mandrel. The clamping device, especially the tie rod, is completed when the cover is closed over the transmission part by connecting the threaded bolt to the threaded sleeve.

[0037] This also creates a preload along the axial direction, clamping the gear component relative to the transport and handling device. This prevents the gear component(s) from accidentally slipping within the transport and handling device, which could result in potential damage.

[0038] It may therefore also be possible for the tension anchor to be formed from a threaded bolt and a threaded sleeve that can be screwed to the threaded bolt.

[0039] The tensioning device, in particular the tension rod, can have other components in addition to the threaded bolt and the threaded sleeve, such as a hook or an eyelet.

[0040] In a further embodiment, the centering mandrel may have at least one centering cone tapering conically toward the top surface on an upper side facing the at least one clamping device, in particular the tie rod. This can significantly facilitate the insertion of the centering mandrel into the transmission part. Furthermore, it can facilitate the placement of the transmission part on the centering mandrel.

[0041] To mount the gear part on a base plate or a plate, for example a spacer plate or on the centering mandrel, the gear part is brought close to the top of the centering mandrel until it is aligned with the centering mandrel and then pushed on.

[0042] According to the invention, the at least one clamping device, in particular a tie rod, penetrates a cover plate and rests against it in a form-fitting manner in an axial direction, absorbing force. The cover plate can be positioned relative to the centering mandrel via guide pins. This further improves the securing of a transmission part during transport and handling.

[0043] According to the invention, it is provided that guide pins have expandable, spreadable or similarly expandable sleeve sections, wherein for expanding the sleeve sections, expansion means preferably designed as screws or similarly designed spreading means are provided, which expansion means or similarly designed spreading means are arranged so as to penetrate the cover plate and connect the guide pins to the cover plate, wherein the expandable sleeve sections penetrate or can be penetrated into corresponding bores on the upper side of the centering mandrel and wherein the centering mandrel and cover plate are connected or can be connected to one another in a frictionally engaged manner.

[0044] Accordingly, it can be provided that the guide pins have expandable sleeve sections which are expanded by screwing in screws, wherein the screws penetrate the cover plate and connect the guide pins to the cover plate, wherein the sleeve sections penetrate into corresponding bores on the top side of the centering mandrel and a frictional connection is created between the centering mandrel and the cover plate when the screws are screwed in due to the expansion.

[0045] This allows the centering mandrel to be secured to the cover plate at its top. The gear component secured with the centering mandrel can thus be moved freely without touching the sensitive functional surfaces. This may be necessary, for example, to initiate machining steps such as cleaning, milling, hardening, nitriding, and deburring. Furthermore, the gear component can also be aligned relative to the planetary gear using the cover plate and the centering mandrel for assembly.

[0046] In a further embodiment, it can be provided that the at least one clamping device, in particular a tension rod, is non-positively connected to a base plate at a distal end, with the gear part being clamped axially between a cover plate and the base plate. This can increase the stability of the transport and handling device. The clamped gear part can thus be transported and handled without damage.

[0047] Thus, an increase in the stability of the transport and handling device can be achieved by the fact that the at least one tensioning device, in particular tension rod, is non-positively connected to a base plate at a distal end.

[0048] The base plate thus holds the gear component axially. In an alternative description, the base plate represents a support surface for a gear component or a plate onto which a gear component can be placed.

[0049] The base plate can therefore also be regarded as the base plate of the transport and handling device, without necessarily having to be limited to this.

[0050] In one embodiment, the wall can be arranged on a sleeve surrounding the gear part. The sleeve can, in particular, protect the outer peripheral functional surfaces of the gear part from damage. The protective effect of the transport and handling device can thus be further increased or improved.

[0051] In a further development of the invention, it can be provided that the transport and handling device further comprises at least one base plate and a cover plate, wherein at least one plate is further comprised which is connected to the base plate and wherein a further plate is comprised which is connected to the cover plate, or wherein the base plate and / or the cover plate is / are designed in a step-like manner, wherein at least one centering mandrel is further comprised which is arranged on the base plate or the plate and wherein a sleeve is further comprised which is designed to be able to envelop a gear part at least in sections on the base plate and / or to be placed on the plate.

[0052] This enables particularly safe transport and handling of transmission parts.

[0053] For the purposes of the invention, "connected" can also mean "contacted" and can be replaced accordingly. For the purposes of the invention, "contacted" can be understood as meaning that individual components, component groups, or components, thus features of the disclosure, are in contact. Conversely, "contacting" for the purposes of the invention can also mean "connecting" or "connected." A flat contact can also be understood and described as "contacting."

[0054] For machining purposes, a plate with a smaller radial diameter can be used if necessary, which does not extend radially outward over an edge of the gear part, so that the sleeve can also be omitted and the gearing remains accessible for machining.

[0055] In a further development of the invention, it can be provided that the base plate and / or plate and / or centering mandrel comprises or comprise at least one recess, wherein at least one desiccant is present in the at least one recess.

[0056] By incorporating a desiccant, damage to the transmission component, such as corrosion, can be counteracted, thus increasing its longevity.

[0057] Desiccants, also known as drying agents, are substances that remove water or other solvents. Water can be chemically bound, for example, with sulfuric acid, calcium chloride, or phosphorus pentoxide. Drying of components can be achieved alternatively or additionally through adsorption, as with molecular sieves or bentonite.

[0058] Silica is an example of a desiccant, but this should not be considered limiting. Experts know how to use suitable desiccants.

[0059] The desiccant can preferably be enclosed in a storage container. This allows for easy replacement.

[0060] The at least one recess can be designed as a channel. This allows for more efficient air circulation and thus better protection for the transmission component.

[0061] The invention further relates to a method for transporting and handling a transmission part, comprising the following steps: a) Placing the gear part on a base plate or a plate of a transport and handling device which comprises at least one wall and slipping the gear part over a centering mandrel which is arranged in contact with the base plate or the plate and which comprises bores, wherein the centering mandrel is penetrated by a clamping device, in particular by a tension rod, b) Slipping a unit comprising a cover plate, a sleeve, guide bolts and a threaded sleeve over the gear part until the guide bolts preferably completely penetrate the bores and the sleeve is flush with the base plate and c) Clamping the clamping device.

[0062] This enables efficient protection of transmission components against damage during transport and handling using simple design measures.

[0063] It may be possible for the centering mandrel to be penetrated essentially centrally by a clamping device, in particular by a tension rod.

[0064] It may be possible for the sleeve to be flush with the base plate in some sections.

[0065] Instead of the term bracing device, the term clamping device can also be used and vice versa.

[0066] In a particularly preferred embodiment, it can be provided that the threaded sleeve is screwed or is screwed onto the threaded bolt, wherein the threaded bolt is connected to the centering mandrel and the threaded sleeve extends through the cover plate and wherein the threaded sleeve rests positively on the cover plate, preferably with a circumferential collar, wherein by screwing the threaded sleeve onto the threaded bolt, the clamping device, in particular the tie rod in the transport and handling device, is clamped relative to the sleeve and the gear part is clamped axially via the guide bolts and the cover plate.

[0067] As a result, it can be ensured that the gear part does not touch the walls due to a mass inertia i2 of the gear part when accelerations act on the transport and handling device and thus cannot be damaged.

[0068] The invention is further described below with reference to the drawings. The scope of the present disclosure is not intended to be limited in any way by the following description. It shows: Figure 1 : schematically in a plan view a planet gear carrier with gears arranged thereon; Figure 2 : schematically shows a transport and handling device for a transmission part; Figure 3 : schematically an open transport and handling device for a transmission part; Figure 4 : a sectional view of a transport and handling device for a transmission part; and Figure 5 : a transport and handling device for a gear part with a sleeve surrounding the gear part.

[0069] The following description of the drawings is merely illustrative in nature. For clarity, the same reference numerals are used throughout the drawings to identify similar elements. It should be appreciated that steps within a method may be performed in a different order without altering the principles of the present disclosure.

[0070] For the sake of clarity, not all combinations of nuts, bolts, and arrangements for transmitting moments and tensile forces can be disclosed. Which part is clamped against which is irrelevant and is covered by the scope of the independent claims as a kinematic reversal.

[0071] In the description of the present disclosure, it is to be understood that orientation or positional relationships may be denoted by the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "top," "bottom," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inside," "outside," "right," "counterclockwise."

[0072] Orientation or position designations are used solely to facilitate and simplify the description of the present disclosure. Orientation or position designations do not imply that the mentioned devices or elements have specific orientations and should be constructed and operated in particular orientations.

[0073] Figure 2 shows a transport and handling device 1 for a gear part 2. The gear part 2 is, for example, a gear of a planetary gear 20, which in Figure 1is shown schematically. The gear part 2 or gearwheel has functional surfaces 71, 74.

[0074] Functional surfaces 71, 74 can assume a function during the intended operation of the transmission part 2, for example a technical interaction with an adjacent component, such as another transmission part 2 or a bearing.

[0075] The entire gear part 2 or the functional surfaces 71, 74 of the gear part 2 can be sensitive to chemical and mechanical environmental influences. Accordingly, the invention provides for shielding the functional surfaces 71, 74 or the entire gear part 2 from mechanical influences and thus protecting them from possible damage.

[0076] One of the functional surfaces 71 can be a double helical gear 11, which, in the case of a sun gear 24 and a planetary gear 25, is arranged on the outer circumference of the gear 2, and, in the case of a ring gear 26, is arranged on the inner circumference. For example, planetary gears for aircraft turbines weigh up to 100 kg, and individual gears are correspondingly heavy. Handling and transporting the gears is made more difficult by the fact that the gears are easily damaged if an attempt is made to grip them externally.

[0077] However, interference with the gear part 2 can also lead to damage, because one of the sensitive functional surfaces 74 can be located centrally in the gear part 2. In the case of the sun gear 24, a shaft-hub connection 14 can be provided on this functional surface 74, which can be designed as a spline. The functional surface 74 on the planet gears 25 corresponds to a machined surface for receiving rolling elements (not shown) of a rolling bearing or an outer sleeve of a rolling bearing 27.

[0078] Referring to Figure 2 comprises the transport and handling device 1 for a gear part having functional surfaces ( Figure 1 ) at least one wall 3, 8. Furthermore, the transport and handling device 1 comprises at least one clamping device, wherein the gear part 2 can be clamped by means of the clamping device, in particular tension rod 9, in such a way that the gear part 2, preferably functional surfaces 71, 74 ( Figure 1 ) of the transmission part 2 is or are arranged at a distance from the at least one wall 3, 8, in particular when accelerations a act on the transport and handling device 1.

[0079] It is particularly preferred that the gear part 2, preferably functional surfaces 71, 74 of the gear part, is / are arranged at a distance from the at least one wall 3, 8, without contact, particularly during accelerations a acting on the transport and handling device 1. This allows for very efficient protection for the gear part with minimal design effort.

[0080] Since functional surfaces 71, 74 are sensitive to environmental influences, particularly to mechanical effects, the invention also provides for shielding the functional surfaces from mechanical influences by at least one wall or walls 3, 8. This can apply analogously to the transmission part 2.

[0081] The at least one wall 3, 8 is designed as a cylindrical wall.

[0082] It is possible, but by no means restrictive, for the tensioning device to be designed as a tie rod 9. It is also possible for the tensioning device to comprise at least one tie rod 9.

[0083] The invention can also be understood and described in such a way that the gear part 2 and the at least one wall 3, 8 are braced relative to one another by tie rods 9 in the transport and handling device 1 in such a way that the gear part 2 does not touch the wall 3, 8 due to a mass inertia i2 of the gear part 2 when accelerations a act on the transport and handling device 1.

[0084] In the embodiment shown, the tie rod 9 has an eyelet 95 or a hook which lies on an axis A9 which extends through a center of gravity S of the transport and handling device 1 and the gear part 2.

[0085] The eyelet is mounted on an axis that also runs through the center of gravity of the device, including the gear unit. This allows the device, including the gear unit, to be lifted without tipping over.

[0086] A wall 8 is provided or present on a centering mandrel 15, which is positioned centrally in a substantially hollow cylindrical gear part 2.

[0087] The centering mandrel 15 is penetrated centrally by the tension rod 9. The centering mandrel 15 has a threaded bolt 91 and a threaded sleeve 92 that can be screwed to the threaded bolt 91. The threaded bolt 91 is connected to the centering mandrel 15, and the threaded sleeve 92 extends along the axis A9 through the cover plate 13. The threaded sleeve 92 bears positively against the cover plate 13 with a circumferential collar 19, so that a preload force F can be applied to the cover plate 13. The preload force F is generated by tightening the threaded sleeve 92 relative to the threaded bolt 91.

[0088] The threaded bolt 91 is counter-locked to the centering mandrel 15 via two nuts 96.

[0089] To increase the contact surface between the nuts 96 and corresponding support surfaces on the centering mandrel 15, washers can optionally be provided.

[0090] The centering mandrel 15 can be arranged to connect and / or contact a base plate 23. The centering mandrel 15 can be arranged to connect and / or contact a plate 44.

[0091] The base plate 23 has an internal thread 97 for receiving the threaded bolt 91. The base plate 23 can thus be screwed onto the transport and handling device 1 from below.

[0092] The base plate 23 is in this case in two parts, the actual axial support of the gear part 2 takes place on a plate 44 arranged between the base plate 23 and the gear part 2, which plate 44 is smaller than the base plate 23 when viewed in the radial direction R. This forms a step between the base plate 23 and the plate 44 and, if a gear part is present, also a gap 99 between the gear part and the base plate 23.

[0093] The threaded sleeve 92 can be tightened or screwed in using a corresponding torque-transmitting area (not shown) on the collar 19. The threaded sleeve 92 can also be tightened or screwed in using the eyelet 95.

[0094] The centering pin 15 has a centering cone 17 on an upper side 16 facing the cover plate 13, which tapers conically towards the upper side 16. The centering cone 17 facilitates, if necessary, the insertion of the centering pin 15 into the gear part 2 according to the Figure 3 .

[0095] Furthermore, the centering cone 29 allows access to an upper nut 96, with which the centering mandrel 15 is fastened to the threaded bolt 91 of the clamping device, in particular the tension rod 9.

[0096] When the cover plate 13, on which a sleeve 12 is optionally arranged, is brought closer to the gear part 2 or the centering mandrel 15 in order to clamp the cover plate 13 relative to the centering mandrel 15, the cover plate 13 obscures the view of the threaded bolt 91. Accordingly, the threaded bolt 91 extends from an inner cone 29, which can facilitate insertion of the threaded sleeve 92 and access to the upper nut 96.

[0097] The cover plate 13 can also be positioned relative to the centering mandrel 15 via guide pins 18. The guide pins 18 extend counter to the axial direction A toward the centering mandrel 15. The guide pins 18 are fastened to the cover plate 13 via screws 22.

[0098] An embodiment with a gear part 2 that is partially accessible from the outside is shown in Figure 4The clamping device or tie rod 9 is non-positively connected at a distal end 93 to a plate 44 that holds the gear part 2 and supports the gear part 2 in the axial direction A.

[0099] For this purpose, the threaded bolt 91 is axially fixed with a nut 98 on the side of the plate 44 facing away from the gear part 2. The gear part 2 is clamped between the cover plate 13 and a base plate 23 in the axial direction A or opposite to the axial direction A.

[0100] The plate 44 seals the gear part 2 at the bottom, preventing media and dirt from reaching the inner functional surface 74. The nut 98 can be removed and replaced with a base plate 23, if necessary, while simultaneously attaching the sleeve 12 to the cover plate 13.

[0101] The plate 44 can be regarded as a cover plate which is arranged on the base plate 23 ( Figure 5). The plate 44 or cover plate can represent a support surface for a gear part, whereby it can be made possible that the gear part can be arranged without contact with the base plate 23 by providing a gap 99 between the gear part arranged on plate 44 and the base plate 23.

[0102] The formed gap 99 enables functional surfaces 71, 74 of the gear part 2 to be arranged without contact with the base plate 23, whereby damage during transport and handling of the gear part 2 can be prevented.

[0103] It may be provided that base plate 23 and plate 44 are formed as a single piece. In this case, base plate 23 is designed in a stepped manner to provide a gap 99. It may also be possible for base plate 23 and plate 44 to be designed as separate components. In this case, plate 44 has a smaller diameter than base plate 23 to provide a gap 99.

[0104] It may also be possible for the base plate 23 to comprise a plate 44. It may also be possible for the plate 44 to comprise a base plate 23.

[0105] In an analogous manner, a plate 54 may be present ( Figure 4), which is arranged on the cover plate 13. The plate 54 or cover plate can represent a support surface for a gear part 2, whereby it can be made possible that the gear part 2 can be arranged without contact with the cover plate 13 by providing a gap 100 between the gear part 2 arranged on plate 54 and the cover plate 13.

[0106] It may be provided that cover plate 13 and plate 54 are formed as a single piece. In this case, cover plate 13 is designed in a stepped manner to provide a gap 100.

[0107] It may also be possible for cover plate 13 and plate 54 to be designed as separate components. In this case, plate 54 has a smaller diameter than base plate 13 to provide a gap 100.

[0108] It may also be possible for the cover plate 13 to include a plate 54. It may also be possible for the plate 54 to include a base plate 13.

[0109] The guide pins 18 point accordingly Figure 4 optionally expandable sleeve sections 21, which are expanded by screwing in the screws 22, wherein the expandable sleeve sections 21 penetrate into corresponding bores 28 on the upper side 16 of the centering mandrel 15 and, when the screws 22 are screwed in, a frictional connection is created between the centering mandrel 15 and the cover plate 13 by expanding apart.

[0110] This allows the centering mandrel 15 to be secured to the cover plate 13 on its upper side 16. The gear part 2, secured or fixed with the centering mandrel 15, can thus be moved freely without having to touch sensitive functional surfaces 71, 74. This may be necessary, for example, to initiate machining steps. Furthermore, the gear part can also be aligned with the cover plate 13 and the centering mandrel 15 relative to, for example, a planetary gear 20 for assembly.

[0111] An embodiment with a gear part 2 that is not accessible or protected from damage is shown in Figure 5 The tensioning device or tie rod 9 is non-positively connected to a base plate 23 at a distal end 93, wherein the gear part 2 is clamped between the cover plate 13 and the base plate 23 in the axial direction A.

[0112] Additionally or alternatively, it may also be possible for the clamping device, in particular the tension rod 9, to be connected or connected to a plate 44 in a force-locking manner.

[0113] The cover plate 23 has a chamfer 30 on its outer circumference, which facilitates centering of the sleeve 12 relative to the base plate 23. A chamfer 31 facing the base plate 23 is also arranged on the sleeve 12. When the chamfer 31 of the sleeve 12 is located close to the chamfer 30 on the base plate 23, the guide pins 18 are already located in the bores 28 on the centering mandrel 15, so that an inclined position of the sleeve 12 relative to the base plate 23 is minimized. Accordingly, it can be ruled out that the sleeve 12, of all things, touches the double helical gear 11 and damages it.
