20110018526 | MEASURING DEVICE FOR MEASURING RELATIVE ROTATIONAL SPEEDS USING WIRELESS SIGNAL TRANSFER - A measuring device for measuring the relative rotational speed of a rotor which rotates with respect to a stator, having at least one inductive pulse generator which is supported by the stator and comprises at least one induction coil in which an electrical voltage which represents a rotational speed measurement signal for the rotational speed is induced by the rotation of the rotor provided with circumferential markings. | 01-27-2011 |
20110260713 | IMPULSE TRANSMITTER AND METHOD FOR PRODUCING SAME - A pulse-type rotation speed transducer and a method for manufacturing the same are described. The pulse-type rotation speed transducer has, as inductive components, a central pole pin, a coil coaxially disposed as a pickup winding around the pole pin and measurement leads, a permanent magnet that is in effective connection with the pole pin, and a sleeve disposed coaxially around the pole pin and the coil. Spacers of an intermediate product ensure coaxial disposition in the context of testing cycles and measurement cycles, cavities within the sleeve being filled with a plastic compound in the context of the final product, accompanied by embedding of the components. | 10-27-2011 |
20110260717 | DEVICE FOR SELF-ADJUSTING AND METHOD FOR ARRANGING AN IMPULSE TRANSMITTER IN RELATION TO A ROTOR - An apparatus for self-adjustment of, and a method for disposing, a pulse-type rotation speed transducer in relation to a rotor are described. The pulse-type rotation speed transducer has a cylindrical sensor head and an adapter to a measurement and power supply cable. An elastic clamping sleeve that radially encompasses the cylindrical sensor head is disposed in frictionally engaged fashion in a bore of a holder, the clamping sleeve forming a press fit for the sensor head in the bore. The press fit enables a rotation and an axial displacement between the holder and sensor head. The pulse-type rotation speed transducer has an active, orientation-dependent, cylindrical sensor head, and the clamping sleeve or the pulse-type rotation speed transducer has a twist prevention system in relation to the holder. The twist prevention system enables an axial displacement of the sensor head in the clamping sleeve with respect to the rotor, for self-adjustment, while maintaining the radial alignment or orientation of the sensor head with respect to the rotor. | 10-27-2011 |

20150176651 | SEAL UNIT FOR ROLLING-ELEMENT BEARING AND ROLLING-ELEMENT BEARING INCLUDING THE SEAL UNIT - A seal unit for a rolling-element bearing having an inner bearing ring and an outer bearing ring. The seal unit includes an at least part-ring shaped element having a seal lip, the at least part-ring shaped element is configured for attachment to the inner bearing ring, and the outer bearing ring is tiltable through a limited angle with respect to the inner bearing ring. Also a rolling-element bearing having such a seal unit. | 06-25-2015 |
20150176652 | ROLLING-ELEMENT BEARING INCLUDING SEAL UNIT - A rolling-element bearing includes a first bearing ring, a second bearing ring, and a seal unit formed in a multiple-piece manner, the seal unit including an at least part-ring shaped main element which is freely rotatable with respect to the first bearing ring and the second bearing ring and at least one seal lip. In addition, the main element and the seal lip are exchangeably connectable to each other. | 06-25-2015 |
20150176654 | ROLLING-ELEMENT BEARING INCLUDING SEAL UNIT - A rolling-element bearing including a seal unit, the rolling-element bearing having at least one bearing ring and a further bearing ring tiltable with respect to the at least one bearing ring by a limited angle, and the seal unit having an at least part-ring shaped element attached to the bearing ring. The at least part-ring shaped element delimits a labyrinthine seal gap and corresponds to a first delimiting element, the rolling-element bearing further includes a second delimiting element and a third delimiting element, the third delimiting element being attached to a bearing cage, and the seal gap extends at least partially between the first delimiting element, the second delimiting element and the third delimiting element. | 06-25-2015 |
