  • Patent number: 10408261
    Abstract: A linear motion guide unit restrains fluctuations in sliding friction and generation of heat by correcting the postures of rollers having been inclined in a no-load area such that their axes become orthogonal to a guide surface of a carriage to thereby introduce the rollers in proper postures into a load area. A retainer plate of the guide unit has a guide surface for guiding end surfaces of the rollers and has protrusions protruding from the guide surface at its opposite end portions facing crownings of the carriage. The rollers rolling from a turnaround passage to a load-carrying race are pressed by the protrusions toward the guide surface of the carriage so as to be arrayed in such a posture that the axes of the rollers become orthogonal to the guide surface on the inlet side of the crowning of the carriage, whereby the occurrence of roller skew is prevented.

  • Patent number: 10400630
    Abstract: Squeeze film damping systems and methods therefore are provided that include features for optimizing the damping response to vibrational loads experienced by a rotary component of a gas turbine engine. In one exemplary aspect, a damping system actively controls a dynamic sleeve to adjust the damping response. In particular, the dynamic sleeve is disposed within a chamber defined by a damper housing. The damping system controls the damper gap by translating the dynamic sleeve. When the dynamic sleeve is translated, a variable damper gap is varied, allowing for fluid to squeeze into or out of the damper gap, thereby adjusting the damping response to the vibration of the rotary component.
