  • Patent number: 11873859
    Abstract: A clamper mechanism for a motion guide device includes a clamper block having tapered faces, clamper rolling elements arranged between the tapered faces and both left and right side faces of a track member, and a clamper rolling element holder attached to the clamper block with an interposition of an elastic member. When an elastic force exerted by the elastic member acts in a direction in which the clamper block and the clamper rolling element holder are separated from each other, the clamper rolling elements bite the tapered faces to bring the clamper block into a state restrained to the track member. When an external force against the elastic force exerted by the elastic member acts, the clamper rolling elements are brought into a free state within the tapered faces to bring the clamper block into a state not restrained to the track member to exert a stable clamping force.

  • Patent number: 11867236
    Abstract: A device for damping a rolling bearing includes a support and a radially flexible cage. The cage includes a ring provided in order to be mounted on the periphery of a rolling bearing. The radial flexibility of this cage results from the structure thereof which is perforated by oblique posts connecting the ring to an attachment annulus of this cage. The support includes a plurality of teeth each extending radially through a respective inter-post opening of the cage. The ring and the support form, radially between one another, a fluid damping cavity suitable for forming a compressed fluid film. The device allows a controlled radial movement of the ring, the latter being radially limited by the support, while having a limited footprint.
