Leveling equipment

Abstract

The invention relates to a leveling device (100) with a housing (110) having an upper part (120) on which a signal unit (150) for generating an optical signal (152) is arranged, wherein , the upper part (120) is rotatably configured relative to the lower part (130) connected to at least one support foot (132, 134, 136), and wherein the signal unit (150) is configured for self-levelling radiation of an optical signal (152 ), a floating ring (180) for sealing and radial clearance reduction is arranged between the lower part (130) and the upper part (120).

Description

technical field [0001] The invention relates to a leveling device with a housing having an upper part on which a signal unit for generating an optical signal is arranged, wherein the upper part is rotatable relative to a lower part connected to at least one support foot ground, and wherein the signal unit can be designed for self-leveling radiation of the optical signal. Background technique [0002] Many leveling devices are known from the prior art, in which a laser beam generated by means of a laser source is projected, for example, onto a wall. Such leveling devices are often subjected to relatively harsh conditions of use, as they are found on construction sites inside or outside buildings. Correspondingly sensitive, precision mechanical and optical components of the leveling device must therefore be reliably protected against the penetration of liquids and foreign particles, in particular water and dust. Housing parts that are immovable relative to each other can be ...

Problems solved by technology

However, conventional sealing by means of O-rings produces too high a friction at the required rotational speed and / or the required rotational precision, and overlapping housing edges must be avoided in order to avoid parasitic grinding effects and to ensure a smooth and precise rotatability with such a high gap size that an adequate sealing effect is no longer obtained

Conversely, sealing by means of multi-stage labyrinth seals would require prohibitively high production costs due to the tight tolerances to be observed.
