Patent number: 8732954Abstract: A typical dynamic bearing design comprises a ring shaped or circular thrust plate mounted at or near the end of a shaft, the shaft defining together with a surrounding sleeve a journal bearing by providing grooves on only one of the two surfaces facing the gap between the shaft and sleeve. On the ring shaped thrust plate supported by the shaft, the traditional upward thrust bearing defined between the lower face of the thrust plate and the facing surface of the sleeve is maintained; but no grooves are on the surface of the thrust plate distant from the shaft and a facing counterplate surface. Further, the journal bearing is defined to have an asymmetry so that a bias force pressure along the surface of the shaft toward the thrust plate is established.Type: GrantFiled: November 19, 2010Date of Patent: May 27, 2014Assignee: Seagate Technology LLCInventor: Anthony J.

Patent number: 8707537Abstract: A security lock assembly includes a channel blocking frame, deadbolt and a pin-lock assembly. The channel blocking frame defines a central opening along a first axis and a pair of opposing apertures along a second axis orthogonal to the first. The deadbolt also defines an aperture or bore extending therethrough for alignment with the frame's opposing apertures when positioned at least partially within the central opening of the channel blocking frame. The pin lock assembly has an elongated shaft dimensioned to extend through opposing apertures of the lock frame and deadbolt thereby entrapping the deadbolt within the channel blocking frame. Enlarged ends of the pin lock assembly prevent unauthorized removal of the pin-lock, the deadbolt, and thus the installed lock assembly from a detachable assembly (e.g., plow). The security lock assembly when secured within an attachment channel of a plow prevents unauthorized attachment without first removing the security lock assembly.Type: GrantFiled: December 27, 2011Date of Patent: April 29, 2014Inventor: Donald E.

Patent number: 8695196Abstract: A system and associated method for disengaging a shrink coupling that secures a shaft to a drive train component, such as a gearbox, includes a reaction plate erected around the shaft at a location displaced from the shrink coupling, with the reaction plate being anchored in place relative to the shaft. A plurality of jacking devices, such as hydraulic jacks, are operationally disposed between the reaction plate and shrink coupling and spaced circumferentially around the shaft. The jacking devices have a first end engaged against the reaction plate and a second opposite end mechanically fastened to the shrink coupling. To remove the shrink coupling from the drive train component, the shrink coupling is released from its clamped state and the jacking devices are activated to exert a pulling force on the shrink coupling, which causes the shrink coupling to be pulled off of the drive train component and moved axially along the shaft to a resting position on the shaft.Type: GrantFiled: November 22, 2010Date of Patent: April 15, 2014Assignee: General Electric CompanyInventor: Richard Arland Ohl, Jr.
