Problems solved by technology
[0010] However, problems can arise when replacing the coaxial operating unit, especially if a pinion is used as the output element which meshes with the corresponding rack of the linear drive
Typically, complex adjustment work is required to ensure that the respective arrangement runs smoothly without backlash, especially due to the practical tolerances in the production of pinions and racks

Embodiment Construction
[0037] exist figure 1 shows a mounting device according to a particularly preferred embodiment of the invention and a coaxial operating unit mounted thereon. The mounting device is marked with 100 as a whole, and the coaxial operating unit is marked with 200 as a whole.
[0038] The mounting device 100 is fixed on the base unit 50 of the stage 1, referring to Figure 3A and 3B Describe the stage. The mounting device 100 comprises an inner shaft 110 located on the inside and a hollow shaft 120 surrounding the inner shaft coaxially. In the example shown, a support sleeve 130 is provided between the inner shaft 110 and the hollow shaft 120 . The support sleeve 130 is fixed in the base unit 50 of the stage in a relatively non-rotatable manner. The inner shaft 110 and the hollow shaft 120 are respectively arranged for rotation in and around the support sleeve 130 .
[0039] A first engagement formation 111 is formed on the inner shaft 110 , a second engagement formation 121 i...

The invention relates to an object stage, which comprises a mounting device (100) for a coaxial operating unit (200) and a coaxial operating unit (200) mounted on the mounting device (200). It is provided that the mounting device (100) has an inner shaft (110) coaxially located on the inside with a first engagement structure (111) and a second engagement structure (121) coaxially surrounding the inner shaft (110). ) hollow shaft (120); the coaxial operating unit (200) has an inner shaft (210) coaxially located inside with a first mating structure (211) and a coaxially surrounding inner shaft (210) A hollow shaft (220) with a second mating structure (221); a non-rotatable first clutch (310) that can be loosened by pulling is formed by the first engaging structure (111) and the first mating structure (211) ; and by the second engaging structure (121) and the second mating structure (221) constitute the non-rotatable second clutch (320) that cannot be loosened by pulling, the second clutch prevents the first clutch (310) from passing through Pull and loosen. The invention also relates to a corresponding stage (10) having one or more mounting devices (100) for mounting a coaxial operating unit (200) and a corresponding microscope (1).
Description
technical field [0001] The invention relates to a stage with one or more mounting means for a coaxial operating unit and a corresponding microscope according to the preambles of the independent claims. Background technique [0002] Stages, especially for microscopes, typically have a base unit that is immovable horizontally relative to the tripod and two slides that are each movable in the horizontal direction. For moving the slide, a coaxial transmission can be provided, which has a coaxially inner inner shaft and a hollow shaft coaxially surrounding the inner shaft. The inner shaft and the hollow shaft are each connected in a rotationally fixed manner to an operating element, in particular a knurled transmission knob, by means of which a rotational movement can be introduced into the inner shaft and the hollow shaft respectively. These rotational movements can be converted in the linear drive into linear movements for moving the carriage via output elements, such as pinio...
