Description

Technical field

[0001] The present invention relates to an arrangement for assembling and disassembling two components, the components being a first component and a second component, wherein the second component can be mounted on or disassembled from the first component. The invention further relates to a method for assembling and disassembling the two components. State of the art

[0002] It is known from the prior art to establish and monitor a relative mounting alignment of components to be assembled in order to prevent damage to the components. This may require determining and monitoring the relative mounting alignment metrologically. Furthermore, it may be necessary to control the relative mounting alignment using actuators.

[0003] However, such measurement and control processes known from the state of the art may, due to the high labor costs involved in the assembly and disassembly of components, provide insufficient solutions to avoid assembly damage.

[0004] DE 10 2008 061 826 A1 discloses a method for joining components, wherein a section of the first component is inserted into a section of the second component by moving one component relative to the other component in a predetermined direction of movement, and wherein at least one of the two components is tempered before the joining process. A first guide body is arranged on the first component and / or a second guide body on the second component, wherein these guide bodies are arranged on the components such that the guide bodies contact their guide part during the joining process before the components or their joining surfaces make contact. Description of the invention

[0005] The present invention relates, in one aspect, to an arrangement for assembling and disassembling two subassemblies. Each subassembly can be a group of components. These subassemblies can be components of a machine, a transmission, or a power unit. The components can therefore be parts of a machine, a transmission, or a power unit.

[0006] The arrangement comprises a first assembly, which includes a first component. The arrangement also comprises a second assembly, which includes a second component. The first and second assemblies can be corresponding subassemblies of a machine, a transmission, or a power unit. The first and second components can be corresponding components of the machine, transmission, or power unit.

[0007] The second assembly can be mounted on or removed from the first assembly. The first component can be arranged or mounted on the second component, or detachable or removable from the first component. The components must be aligned relative to each other for the assembly and disassembly of the subassemblies. Assembly and disassembly may require alignment and a specific arrangement of the components relative to each other, whereby the subassemblies can be assembled and disassembled as intended if the components are aligned relative to each other. For example, the components must be aligned orthogonally to an assembly and disassembly direction for the assembly and disassembly of the subassemblies. The assembly and disassembly direction can be an axial extension direction of the subassemblies and components, or a longitudinal extension direction of the subassemblies and components. The assembly and disassembly direction can be spatially inclined.

[0008] The assembly includes a guide device for aligning the components. The aligned arrangement of the components can be a mutually exclusive arrangement that allows for impact-free assembly and disassembly. The guide device can predefine the alignment of the components and bring about the aligned arrangement. The guide device is predefined on the first assembly. The guide device can be predefined on the first assembly with respect to an axial direction of the first assembly. The axial direction of the first assembly can be spatially inclined. The second assembly is movably guided on the guide device. The second assembly can be movably guided on the guide device along the axial direction of the first assembly.The second assembly can be predefined on the guide device. The second assembly can be predefined on the guide device with respect to an axial direction of extension of the second assembly. The axial direction of extension of the second assembly can also be spatially inclined.

[0009] The second component is connected to the guide device via a support tool, which supports the second assembly at its center of gravity. The support tool can be movably guided on the guide device.

[0010] This arrangement allows the components of the assemblies to be passively or indirectly aligned, with the components being aligned relative to each other via the guide device. The arrangement enables the components of the assemblies to be aligned without having to position or attach the support device to the housing components of the second assembly. Due to the predefined arrangement of the first assembly and the guiding of the second assembly at its center of gravity by means of the guide device, the assemblies can be reliably assembled and disassembled even with a spatially inclined assembly and disassembly direction. The components of the assemblies can be aligned relative to each other depending on the predefined arrangement of the first assembly and the guiding of the second assembly at its center of gravity.

[0011] According to one embodiment of the arrangement, the guide device can have a guide rail on which the second assembly is slidably mounted. The second assembly can be slidably mounted on the guide rail along the axial direction of extension of the first assembly. Alternatively, the second assembly can be slidably mounted on the guide rail. In this way, the components can be efficiently aligned in the radial direction of extension of the first assembly.

[0012] According to a further embodiment of the arrangement, a central axis of the first component can be spatially inclined. The central axis of the first component can be a central axis or an axis of symmetry. A central axis of the second component can be inclined relative to the central axis of the first component. The central axis of the second component can be a central axis or an axis of symmetry. The center of gravity of the second component can be spatially offset from the central axis of the first component. This spatial offset can be vertical. Alternatively or additionally, the spatial offset can be horizontal. The components to be aligned can therefore be arranged radially relative to their axial directions in an inclined arrangement.The axial extension directions of the components can correspond to the axial extension directions of the assemblies.

[0013] According to a further embodiment of the arrangement, the support tool can engage with the second component. The engagement of the support tool with the second component can predefine the center of gravity of the second assembly. The support tool can be designed such that its engagement with the second component occurs at the center of gravity of the second assembly. For this purpose, the support tool can be dimensioned accordingly. The engagement area of ​​the support tool with the second component can be spaced apart from a region of the second component that is to be aligned with the first component. Therefore, the engagement area where the support tool engages with the second component can be different from or facing away from a region of the second component that is to be aligned with the first component.

[0014] According to a further embodiment of the arrangement, the support tool can have an adjustment device via which the second component is connected to the guide device. The adjustment device can be configured to set a support force acting on the second component. The adjustment device can be configured to set a relative position of the second component to the first component. If the weight of the second assembly acts on the guide device when it is mounted on the guide device, this weight force can result in deformation of the guide device. The adjustment device can be configured to compensate for this deformation by means of the support force. The deformation can take the form of a deflection of the guide device. In this way, a relative alignment error of the components to be aligned, which can result from the deformation of the guide device, can be eliminated.If the components to be aligned are in contact, the support force can be adjusted in such a way that damaging friction between the components can be minimized or avoided.

[0015] According to a further embodiment of the arrangement, the adjusting device can have an acting element that acts on the second component to at least partially compensate for the gravitational force exerted on the second assembly in the vertical direction. The acting element can, for example, be a spring. The acting element can also be an actuator. The acting element can be configured to completely compensate for the gravitational force exerted on the second assembly. The acting element can be configured to maintain a relative position of the second component with respect to the guide device. The acting element can be configured to maintain the relative position of the second component regardless of the weight of the second assembly. The relative position can be predefined such that the components are aligned with each other.

[0016] According to another embodiment of the arrangement, the first component can be a first gear component and the second component a second gear component. For example, the first gear component comprises planet gears of a planetary gear set and the second gear component a sun gear of the planetary gear set. The planet gears and the sun gear can be the components to be aligned. In another example, the first gear component comprises a ring gear of a planetary gear set and the second gear component a gear set consisting of planet gears and a sun gear of the planetary gear set. The ring gear and the gear set can be the components to be aligned.

[0017] According to a further embodiment of the arrangement, the first assembly can comprise a gear stage of a planetary gearbox of a wind turbine. The second assembly can comprise a further gear stage of the planetary gearbox of the wind turbine. An axial extension direction of the gear stage of the first assembly can be inclined on a nacelle of the wind turbine. The first component can therefore be a gear component of the gear stage. The second component can therefore be a gear component of the further gear stage.

[0018] The present invention relates in a further aspect to a method for assembling and disassembling two subassemblies. The arrangement according to the preceding aspect can be used to carry out the method. The subassemblies can be those described in the preceding aspect.

[0019] The process includes, as one step, a predefined arrangement of a guide device on a first assembly, which comprises a first component. The guide device, the first assembly, and the first component can be the same as those described in the previous section.

[0020] The process includes, as a further step, the arrangement of a second assembly, which can be mounted on or removed from the first assembly and which comprises a second component, on the guide device. The second assembly and the second component can be the same as those described in the previous section. The components must be aligned relative to each other for assembly and disassembly. The second component is connected to the guide device via a support tool, which supports the second assembly at its center of gravity. This support tool can be the same as those described in the previous section.

[0021] The method includes, as a further step, guiding the second assembly along the guide device to align the components. According to one embodiment of the method, a further step involves adjusting a support force acting on the second component. During this adjustment step, the relative position of the second component to the first component can be set.

The second assembly 20 comprises a second component 21, which, according to the embodiment, is a sun gear of the further gear stage of the second assembly 20. The ring gear and the sun gear can be gear components of a planetary gear set. The arrangement 100 is configured to align the ring gear and the sun gear relative to each other during assembly of the second assembly 20 onto the first assembly 10 and during disassembly of the second assembly 20 from the first assembly 10.

[0025] The arrangement 100 includes a guide device 30, which is arranged and configured to align the components 11, 21 radially with respect to each other.

If the guide device 30 has two guide rails 32, these are oriented substantially parallel to each other.

[0026] The second assembly 20 is guided translationally along the guide rail 32 by means of a guide slide 34. The second component 21 is connected to the guide device 30 via a support tool 40, which supports the second assembly 20 at its center of gravity 22. The support tool 40 has a cone 44 that engages in the second assembly 20 and supports it at its center of gravity 22.

[0027] The cone 44 is also attached to the second assembly (though not shown). According to one embodiment, the cone 44 engages a predefined component 23 of the second assembly 20, which is either the second component 21 or another transmission component of the second assembly 20. In one embodiment, the predefined component 23 is a transmission bearing arranged coaxially with the second component 21. The support tool 40 is dimensioned such that the translational guidance along the guide rail 32 and the engagement with the predefined component 23 at the center of gravity 22 of the second assembly 20 ensure the radial alignment of components 11 and 21 during assembly and disassembly.

[0028] The support tool 40 also has an adjusting device 42 with which the relative position of the second assembly 20 to the guide rail 32 can be adjusted. The adjusting device 42 has an active element 43 which is configured to compensate for the gravitational force of the second assembly 20.

[0029] Fig. Figure 2 shows a flowchart with steps for carrying out a procedure for assembling and disassembling the assemblies 10, 20 in a temporal sequence according to an embodiment.

[0030] In a first step S1, the guide device 30 is predefined and positioned on the first assembly 10 as described. In a second step S2, the second assembly 20 is positioned on the guide device 30, with the second component 21 being connected to the guide device 30 via the support tool 40.

[0031] In a third step S3, the second assembly 20 is guided along the guide device 30, with the second assembly 20 being supported at its center of gravity 22. This step aligns the second component 21 with the first component 11. In a further optional step S4, the relative position of the second component 21 to the guide device 30 is adjusted.
