  • Patent number: 11813801
    Abstract: A method may produce an axially movable connection between two components with a plastic as a sliding material arranged therebetween. The method may involve providing the two components and either at least one of the two components has a plastic coating or a plastic sleeve is provided between the components, joining the two components to form a unit via a pressing force in an axial direction, clamping the unit in a device in which the two components are clampable and subjectable to a displacement force in the axial direction, pressing a sonotrode against an outer of the two components and bracing the outer component against a counter-holder, injecting an ultrasound signal into the sonotrode and moving the two components back and forth in the axial direction until a displacement force or a displacement velocity reaches a target, and ending the ultrasound signal and removing the unit from the device.

  • Patent number: 11072128
    Abstract: A method for producing an axially movable connection between two tubular components with a plastic as a sliding material therebetween may involve providing the components to be joined where either at least one of the two components has a plastic coating or a plastic sleeve is provided between the components, joining the components to form a unit via a pressing force in an axial direction, clamping the unit in a device in which the components can be clamped and subjected to a displacement force in the axial direction, pressing a sonotrode against an outer of the two components, injecting an ultrasound signal into the sonotrode at a frequency close to the resonance frequency of one of the components, and moving the tubular components back and forth in the axial direction until the displacement force or the displacement velocity reaches a target, and ending the ultrasound signal.
