Embodiment Construction

[0030] The individual stated features, details, advantages and effects of the present invention emerge from the following description of preferred embodiments of the present invention in conjunction with the following drawings.

[0031] figure 2 A non-stepped contour or geometry 11 is shown, in particular a v-shaped or ramp-like contour in the bearing ring 6 opposite the distance sensor 4 . In this advantageous first embodiment of the invention, the sensing or detection end of the distance sensor 4 in the bearing ring is connected to the continuously changing contour or geometry in the axial direction in the opposite bearing ring 11" relative to each other.

[0032] figure 2 It also exemplifies the following design methods:

[0033] This non-stepped geometry is in figure 2 different from the prior art (see figure 1 ) in the form of a ramp 11". This has the particular advantage that when one bearing ring is offset in the axial direction relative to the other, the end A ...

Abstract

The invention relates to a moment or rolling bearing arrangement (1) or a rotary connection (1), having at least one distance sensor (4), which senses in a contactless manner, preferably measures or detects by an inductive method, alternatively measures or detects by means of a sound wave or eddy current method, where necessary measures or detects by means of a capacitive method, for the at least intermittent, but preferably constant, measurement or sensing or detection of the axial distance (As) or displacement and / or radial distance or displacement (Av) of at least two bearing rings (6; 7) relative to each other in the bearing gap (10) thereof, wherein the at least one distance sensor (4) is fixed or introduced into one of the bearing rings (6; 7) and in relation to a non-stepped contour or geometry (11) by a suitable means (9), preferably by one sensor bore per distance sensor (4), wherein the non-stepped contour or geometry (11) has either a v-shaped contour (11') or a ramp-shaped contour (11"), for example having a constant gradient, or a rounded contour (11"'), where necessary in a similar manner to a well, or a raised portion (11 *), which is formed for example by additional bodies (12).

Description

technical field [0001] The invention relates to a moment or rolling bearing arrangement, optionally also in the form of a large rolling bearing, alternatively a rotational connection, which has at least one non-contact sensing, preferably inductive A distance sensor for measuring or detecting by means of an acoustic method or an eddy current method, if necessary by means of a capacitive method, for at least temporarily, but preferably continuously, measuring or detecting at least Axial spacing or axial offset and / or radial spacing or radial offset of two bearing rings relative to each other in their bearing gap, wherein at least one spacing sensor is provided with suitable means, preferably each sensor bores, which are fixed or introduced into at least one of the bearing rings and are fixed or introduced facing a non-stepped profile or geometry, wherein the non-stepped profile or geometry either has a V-shaped profile or a ramp-like profile, For example with a continuous grad...
