Definitions
- the invention relates to a moment or roller bearing assembly, also iff as.
- a moment or roller bearing assembly also iff as.
- a rotary joint having at least one contactless sensing, preferably by inductive method measuring or detecting, alternatively by means of sound waves or eddy current method measuring or detecting, optionally measuring by means of capacitive method or detecting, distance sensor for at least temporary, but preferably continuous, measurement or detection of the axial distance or the axial displacement and / or the radial distance or the radial displacement of at least two bearing rings relative to each other in the bearing gap, wherein the at least one distance sensor via suitable Means, preferably via a respective sensor bore has, which is fixed or introduced at least in one of the bearing rings and against a non-stepped contour or geometry, wherein the non-stepped contour or Geometry either a V-shaped contour or a ramp-shaped contour, for example, with a continuous slope, or a rounded contour, possibly similar to a Kuhle, or a survey, for example, which is formed
- each rolling bearing or each slewing bearing as well as a rotary joint and / or a moment bearing, calculated and designed for a certain life.
- the aforementioned damage or destruction begins, for example, with the formation of material breaks and / or depressions in the raceway, since the track is often designed in lower hardness than the cooperating with them rolling elements. These depressions can become larger with increasing operating time and lead to breakouts in the career. With continued use of the rolling bearing these breaks sometimes lead to even larger material outbreaks, which can then cause a sudden blocking of the bearing, which can lead to failure of the entire machine or the vehicle, used in or in the camp or the rotary joint becomes. In addition, by means of the aforementioned outbreaks, spacers or cage segments possibly present in the storage system can be damaged,
- probes or sensors which are electrically supplied or coupled with electrical leads, are frequently used, which as a rule work without contact, ie.
- emit waves such as mechanical waves such as sound waves or electromagnetic waves. 1 shows such a large-diameter rolling bearing according to the conventional art.
- the sensor or the probe of the wear measuring device is not installed flush with the diameter of the inner ring, this can be damaged or even destroyed due to breakages or shavings of metallic material located in the raceway system.
- this groove will very likely accumulate with lubricant, especially grease, as well as with metal particles of the aforementioned bursts or breaks. These particles can significantly influence or disturb the sensor signal or the transmitted waves. The quality of the sensed or measured or detected signal suffers due to these influences or disturbances partly considerable. Frequently, the quality of the sensor becomes so bad that the entire result of the sensing must be called into question.
- this groove and the position of the sensor or probe must be aligned in such a way that radial wear or tilting of the bearing can be detected by the sensor or the wear measuring device.
- this is only possible if the sensor tip or probe tip precisely "points" at the groove, which is the case when the bearing is loaded only in the radial direction and does not experience any tilting in the axial direction
- tilting of the bearing in the axial direction almost always occurs, as a result of which the groove is moved in the axial direction or, at least as a result of the torque, is rotated by a certain angular offset in the axial direction
- Probe tip can "aim” at axial tilting or tilting of the bearing, or in general at axial displacement of the bearing, then on the edge or edge region of the groove.As the edge region of a groove is always bounded by a step formation, that of the sensor tip or the Probe tip sensed value thereby change abruptly.
- the solution to the problem is achieved by mounting in the axial and / or radial direction measuring or detecting distance sensors at defined locations of the bearing ring or the bearing rings, wherein such a distance sensor respectively the distance or the relative movement between the body (bearing ring) and measuring device (distance sensor ) is capable of sensation.
- This relative movement can either result from the wear of bearing components, or - possibly in superimposing manner - from the action of loads on the bearing or the rotary joint, ie due to externally applied forces and / or moments originate.
- At least one contactless sensing preferably a measuring or detecting by inductive method, alternatively by means of ultrasonic or eddy current method measuring or detecting, possibly by means of capacitive method measuring or detecting, distance sensor for at least temporary, but preferably continuous, measurement or detection of the axial distance (As) or the axial displacement and / or radial displacement ( ⁇ ) or the radial distance of at least two bearing rings is used relative to each other.
- This at least one distance sensor is preferably introduced by suitable means in the bearing gap between the respective mutually rotatable bearing rings, preferably via a sensor bore in one of the bearing rings that compared to the distance sensor is given a non-step-like contour or geometry, this non-stepped contour or geometry in is located opposite the distance sensor bearing ring and about the width of the bearing gap, preferably at least 0.20 mm, ideally between 0.20 and 9.5 mm or even between 1.0 mm and 4.0 mm, optionally spaced by the width of the bearing gap +/- 0.2 to 3.5 mm from the distance sensor is.
- the non-stepped contour or geometry in this case has either a V-shaped contour or a ramp-shaped contour or a rounded contour.
- this non-stepped contour or geometry may be through or from one Additional body are formed, which is introduced or fixed in those bearing ring, which is opposite to the distance sensor.
- the invention relates not only to the use in rolling or moment bearings, but also to all types of slewing and slewing bearings, ideally for use in machines and equipment and vehicles such as: tunnel boring machines, stackers, construction machinery, agricultural machinery, cranes , Mobile cranes, aerial work platforms, wind turbines, tidal power plants, medical apparatus, for rotatably adjusting carriages in military vehicles or for adjusting water cannons on fire engines, for rotary storage of turbines and / or rotors in power plants, in solar systems, rides in amusement parks, et cetera.
- the invention is also used in rotary joints of rotary actuators, also called “swivel drives", and associated with associated worm gear systems.
- torque or roller bearings or slewing bearings and or rotary joints can be designed as a barrel roller bearing, cylindrical roller bearings, needle roller bearings, tapered roller bearings or even as ball bearings, with at least one row of rolling elements. Alternatively, even as a cross roller bearing or combination bearing or even in the design of a four-point ball bearing.

- this non-stepped geometry 1 1 is separated by a separate body, the so-called auxiliary body 12, into the moment or (large) rolling bearing 1 or in the rotary joint 1.
- This additional body 12 may be approximately a circumferential ring, as described below.
- this vertex S is designed as a tip. This results in an analytical discontinuity of the non-step-like contour 1 1 in the apex S.
- this vertex S is shown as the highest point on a curve contour 1 1, in which case the analytic continuity at the apex S given is.
- the vertex S thus serves as a kind of zero position or as a kind of reference position for the measured values or measurement results of a non-contact distance sensor 4. According to the hitherto conventional technique in the sense of FIG. 1, this is clearly not possible, since even with axial displacement of the large rolling bearing G. the sensor 4 always points to a groove 5, said groove along its foot always has an equally high penetration depth.
- a dedicated information about the displacement path in the axial direction As is not given in a slewing bearing according to Fig. 1.
- the vertex S of the non-step-like contour or geometry 1 1 in the sense of the invention indicates the location of the maximum elevation - or alternatively the location of the maximum notch as shown in Fig. 2 - the non-stepped contour or geometry 1 1 with respect to this contour. 1 1 accommodating bearing ring 6 and thus provides feed for an evaluable path information in the axial direction As, the conventional art, see. Fig. 1, without.
