  • Patent number: 11784539
    Abstract: The disclosure relates to an assembly comprising a component rotatable about a rotary axis for an actuating drive comprising a sensor element attached to the rotatable component. The rotatable component has a support surface from which a fixing element protrudes in parallel to the rotary axis. The sensor element includes an opening. The sensor element is arranged on the support surface in such a manner that the fixing element penetrates the opening. A surface of the sensor element adjacent to the opening has a structure. A top portion of the fixing element is in interlocking engagement with the structure so that the attached sensor element is connected to the component in a torque-resistant manner.
    Type: Grant

  • Patent number: 10424992
    Abstract: The invention relates to a fluid-dynamic bearing system, in particular for the rotary support of a spindle motor, the bearing system comprising: a first conical bearing and a second conical bearing counteracting the first conical bearing, a fixed shaft along which the two conical bearings are arranged, a sleeve, a first and a second conical bearing component, which together with the sleeve form the first and second conical bearings, bearing structures applied to the sleeve and/or the conical bearing components, a bearing gap filled with a bearing fluid extending between the sleeve and the shaft and between the sleeve and the conical bearing components and sealed at each of its ends by a conical capillary seal, and a hub which rotates together with the sleeve about a rotation axis. The invention is characterized in that a pump seal is arranged between the first conical bearing and the adjacent capillary seal.
