Description

Technical field The following descriptions relate to an assembly device for positioning a gap seal in a gap of a bearing, in particular a blade bearing, which enables simple, quick, and reliable assembly. Furthermore, the following descriptions relate to a method for positioning a gap seal on a bearing. Technical background From the DE 20 2012 104 057 U1 A bicycle tire lever is known to assist in removing and installing bicycle tires or inner tubes on/off rims. The printed text DE 10 2006 053 832 A1 This concerns an element for sealing a rolling bearing, in particular a blade bearing for wind turbines. The publication DE 10 2011 109 605 A1 deals with an assembly tool and method for attaching an elastic seal to the frame of a vehicle door. From the EP 2 672 133 B1 A large rolling bearing with a gap seal that seals the gap between the bearing rings is known. The object of the invention is to provide an assembly device for improving the ease of mounting gap seals on large slewing bearings, in particular blade bearings of wind turbines. Such large slewing bearings often have diameters of several meters. Accordingly, the gap seals also have a diameter of several meters. Based on this situation, the task at hand is to propose an assembly device that simplifies the assembly of a gap seal and reduces the required assembly time. Description - Technical Solution The present problem is solved by the features of the independent claim. Advantageous embodiments are specified in the dependent claims, the description, and the drawings. Where technically feasible, the teachings of the dependent claims can be combined arbitrarily with those of the main and dependent claims. In particular, the problem is solved by an assembly device for arranging a gap seal at least partially in a gap of a bearing, in particular a blade bearing, extending axially and circumferentially between an inner bearing ring and an outer bearing ring, wherein the gap seal has a circumferentially extending first sealing lip with at least one first sealing edge, which forms an assembly groove open towards the gap for at least partial reception of the assembly device, wherein the first sealing lip is further designed for positioning within a sealing groove open towards the gap and extending circumferentially along the inner or outer bearing ring, wherein the assembly device has a curved base body for screwing the first sealing lip into the sealing groove and a first end section arranged on the base body with a receiving edge for positive and/or force-fit arrangement in the assembly groove of the gap seal, wherein the assembly device further has a handle element arranged on a second end section for handling and guiding the assembly device during assembly, and wherein the assembly device has a drive element extending from the base body for positive locking The contacting of a sealing foot of the gap seal which can be positioned within an anchor groove, wherein the driving element is designed for positive engagement of a sealing foot of the gap seal which can be positioned within an anchor groove in the direction of the gap. The mounting device allows the gap seal to be easily and cost-effectively positioned on the bearing. In particular, the first sealing lip can be screwed into the sealing groove over the gap. This is made possible primarily by the curved base body of the mounting device, which has a substantially convex-concave cross-section. The following sections explain advantageous aspects and subsequently describe preferred modified embodiments. Explanations, particularly regarding advantages and definitions of features, are essentially descriptive and preferred, but not limiting, examples. If an explanation is limiting, this will be explicitly stated. It is preferred that the sequence of process steps can be varied, unless a specific sequence is technically required. However, the aforementioned sequence of process steps is particularly preferred. Insofar as ordinal numbers, for example "first", "second", etc., are used, for instance to designate a component, an element, a process step or a procedural action, these ordinal numbers are purely for the purpose of Differentiation is provided in the designation and does not indicate dependencies or sequences. This means, in particular, that a device does not need to have a "first component" to have a "second component." A device can also have a "first component" and a "third component" without necessarily having a "second component." Multiple units with the same ordinal number are also possible, for example, multiple "first components." Alternatively or additionally, the assembly device may include a drive element extending from the base body for positive-locking contact with a sealing foot of the gap seal that can be positioned within an anchor groove. In particular, the drive element is designed to positively engage a sealing foot of the gap seal, which can be positioned within an anchor groove, in the d
