Definitions
- Rotary connection with at least one rolling bearing and with an electric motor drive unit wherein the rolling bearing is ver ⁇ seen with at least one arranged around the axis of rotation of the rolling bearing rolling element in contact with at least one drivable by the drive unit career ver ⁇ .
- a rotary joint is described in DE 10210071 A1.
- Integrated and low-noise rotary joint systems can be used in a variety of applications and are generally used for driving, for connection and support and for position detection of the rotating masses and their coupling to static components.
- roller bearing slewing rings are used in computer tomographs. Furthermore, one finds the rolling bearing rotary joint in similar X-rayographic devices for examining luggage in the security area z. At airports. With the steady increase in the speeds of these applications with simultaneous requirement for reduced noise, low starting torque, small installation space, low weight and high running accuracy, known roller bearing slewing rings are unsuitable and no longer satisfy the requirements of this application.
- the task is to create a rotary joint that meets the requirements mentioned above.
- a measurable running noise on the electric motor driven Drehver ⁇ binding measured as airborne sound, total sound pressure level with values of at most 70 dB (A), preferably 67 dB (A).
- the noise measurement is carried out at a 1 m horizontal distance from the bearing plane on the theoretically continued line of the axis of rotation.
- the rolling bearing has at least one inner raceway and an outer raceway. Also conceivable are several of the raceways in the rolling bearing.
- the rolling elements are in contact, during operation of the rolling bearing in the rolling contact, with at least one inner race and an outer race, alternatively with axially aligned raceways.
- the rolling elements circulating in the rolling bearing cause noises in the form of structure-borne noise.
- a structure-borne sound insulation of the rolling bearing hinders the propagation of structure-borne noise into the conversion parts and thus reduces the noise.
- the material used for structure-borne sound insulation has an impedance ratio p of at least 3 in comparison to the material of the rolling bearing ring.
- the impedance ratio p is defined as follows:
- a further feature of the low-noise roller bearing is the surface area of the raceways, which is determined by a defined waviness and / or surface roughness.
- the roughness of the raceway is not greater than Ra 0.25.
- the indication Ra is a well-known and interna- Normalized value, which is defined as the arithmetic mean according to DIN EN 4287:
- the well-known concept of waviness is based on the following features:
- At least the surface of the raceway is described by any number of mutually parallel generatrices with circumferentially wavy, and thus deviating, from the imaginary about the Rotations ⁇ axis circulating perfectly circular formed ide ⁇ alverlauf, courses,
- the courses are respectively described by waves which alternate successively in the circumferential direction (about the axis of rotation) and repeatedly cut the respective ideal course
- the measuring range is determined by the arc length along the respective track between the respective contacts with the track of two circumferentially successive rolling elements of a row.
- a trained according to invention low-noise rotary connection system Rolling and drive unit is compact and takes up little Bau ⁇ space. It safely absorbs high radial, axial and moment loads.
- the direct drive is preferably an integral part of the Drehitatis ⁇ system and therefore requires no additional space.
- the rotating rotary connection system causes particularly low speeds in all speed ranges above 100 rpm (1 / min), preferably from 160 rpm through the integration of a particularly quiet running rolling bearing, optionally combined with the structure-borne sound insulation noise levels. Due to the small number of components used and their compactness, the rotary connection can be produced cost-effectively.
- the direct drive ensures that the drive forces of the direct drive without the interposition of other drive components (such as, for example, belts or gears, etc.), brake generator deflecting and tensioning rollers, are transferred to the rolling bearing slewing connection.
- other drive components such as, for example, belts or gears, etc.
- brake generator deflecting and tensioning rollers are transferred to the rolling bearing slewing connection.
- the electric motor drive unit which is preferably integrated as a direct drive into the rotary connection, is designed as a torque motor in ring or segment construction, wherein a static component of the rotary connection is connected to at least one stator consisting of iron cores and electrical windings.
- a static component of the rotary connection is connected to at least one stator consisting of iron cores and electrical windings.
- One of the rotating components of the Drehver ⁇ bond is equipped with permanent magnets.
- different engine outputs can be provided by assembling one or more individual segments up to a completely closed ring for driving with the aid of the torque motor in segment design or as a ring motor.
- Their total drive power depends on the number and size of the stator segments used. If only low rotational speeds and small torques are required, wide gaps can be left between the individual stator segments. The torque motor is too then still operable, if only a stator segment is arranged in the case of a lower required An ⁇ drive power. At high varnish ⁇ required for active rotation, acceleration or deceleration of Dreh ⁇ connection system is then to choose the ring motor design.
- a torque motor In contrast to the ring motor, a torque motor has to be operated in a segmented fashion in order to synchronize the magnetic forces of each individual segment, thus achieving the best possible efficiency and the lowest noise level.
- the required input signal of the frequency converter for controlling the Seg ⁇ elements is provided according to an embodiment of the invention by the integrated sensors for position detection. If very high rotational moments are required (for example in the case of a short start-up phase of the rotating components), efficient operation of the ring motor is likewise possible due to the controlled operation. Due to the controlled operation of the drive unit, high torques can be realized with a simultaneously lower power level of the frequency converter.
- a position measuring system can additionally be integrated into the rotary connection system with the sensor system.
- the sensor system has at least one sensor and a signal transmitter.
- the sensor is used for detecting signals of the signal transmitter (coding) or else several of the abovementioned components of any design.
- the coding is formed by an elastomeric belt which is offset by alternating polarized magnetized particles (alternately north and south poles).
- the sensor system can also have other electronic components, for example converters.
- the rolling bearings are single-row or multi-row.
- the rolling elements are balls or rollers that can be held in cages.
- the material of the rolling elements and the raceways is preferably steel or any other conceivable materials, such as the materials with a density that is less than 5 grams per cubic millimeter. Such materials are, for example, ceramic materials.
- the ratio of diameter pitch circle to the diameter of each of the rolling elements of a row is greater than 30: 1, preferably 40: 1 for such bearings, wherein the pitch circle is the imaginary circle, which is arranged concentrically to the axis of rotation and which, irrespective of possible changes in position of Wälz ⁇ body due to games in the rolling bearing which intersects parallel to the axis of rotation aligned center axes of the rolling elements
- the central axes are in roles the rotation or symmetry axes and spheres thought by the ball center and parallel to the axis of rotation Dreh ⁇ connection extending axes.
- the thin-ring four-point ball bearing is the simplest and most robust Lager ⁇ design. It is designed so that average axial, radial and moment loads can be safely absorbed.
- the thin ring bearing with its low intrinsic and dimensional stability is supported by the installation in the surrounding parts.
- wire web bearings angular contact ball bearings and roller bearings are used.
- a conversion part is, for example, a housing in which the rolling bearing, or at least one of the bearing rings or at least one of the raceways is integrated and / or a rotor or a shaft on the / the Rolling, or at least one of the bearing rings or at least one of the raceways is arranged.

- a structure-borne sound insulation 10 in the form of a vulcanized on the outer ring 8 insulating layer 11 made of an elastomer.
- the insulating layer 11 is alternatively an insert.
- a rotary motor of the drive unit 3 has permanent magnets 12 which sit directly on a rotor 13 of the rotary joint 1.
