Patent number: 9958009Abstract: A roller bearing includes an inner ring having an inner-ring raceway surface on an outer periphery of the inner ring, an outer ring arranged concentric with and peripherally outside the inner ring and having, on an inner periphery of the outer ring, an outer-ring raceway surface that faces the inner-ring raceway surface, a plurality of rollers interposed between the inner-ring raceway surface and the outer-ring raceway surface in a rollable manner, and a cage that holds the rollers at predetermined intervals along a circumferential direction. Opposite end portions of the outer-ring raceway surface in an axial direction serve as guide surfaces or which rotation of the cage is guided. Or an outer periphery of the cage, slidable contact surfaces are formed which slidably contact the guide surfaces and which are arranged to face the respective guide surfaces across a labyrinth clearance.Type: GrantFiled: December 28, 2016Date of Patent: May 1, 2018Assignee: JTEKT CORPORATIONInventors: Yuki Shishihara, Shigeo Kamamoto, Junji Murata

Patent number: 9958010Abstract: A sliding component, which can seal and lubricate at the same time by reducing the amount of leakage of sealed fluid further while preventing torque increase and local wear, is characterized in that an extremely shallow step of circular shape is provided on a sealing face of one of a pair of sliding parts that slide against each other in such a way that the step is positioned on the low-pressure fluid side (atmosphere side) of this sealing face and also set lower than the sealing face, and that pumping grooves acting to push back toward the high-pressure fluid side (sealed fluid side) the fluid that tends to leak from the sealing face toward the low-pressure fluid side (atmosphere side) are provided on the surface of the extremely shallow step.Type: GrantFiled: July 31, 2013Date of Patent: May 1, 2018Assignee: EAGLE INDUSTRY CO., LTD.Inventor: Masatoshi Itadani

Patent number: 9958011Abstract: A bearing assembly has an outer race, which has an arcuate inner surface and an inner member that is partially disposed in the outer member and which has an arcuate outer surface. The inner member has one or more hubs that extend axially from the inner member. The one or more hubs each have one or more circumferentially extending surface depression that is positioned proximate the arcuate outer surface. The one or more hubs each have one or more circumferentially extending surface protrusion that is positioned axially outward beyond the at least one circumferentially extending surface depression.Type: GrantFiled: June 18, 2015Date of Patent: May 1, 2018Assignee: ROLLER BEARING COMPANY OF AMERICA, INC.Inventor: Moises Polanco

Patent number: 9958012Abstract: The second lip has an annular protrusion formed at one end portion in a thickness direction of a lip tip portion configured to be in sliding contact with the slinger and protruding in the thickness direction, and a thickness of the lip tip portion is formed thicker than a thickness of a lip part except for the protrusion. The protrusion is formed to be reduced in width toward the tip-side in the thickness direction and configures a sliding contact part configured to be in linearly sliding contact with the slinger. The circular plate part of the slinger is formed tilted toward the seal member in the axial direction, and the slinger has an annular flange part integrally formed therewith by bending a tip of the circular plate part so as to axially cover an area above the sliding contact part of the seal member.Type: GrantFiled: January 22, 2015Date of Patent: May 1, 2018Assignee: NSK LTD.Inventor: Takahisa Nakata

Patent number: 9958013Abstract: An assembly comprises a component and a spherical bearing mounted in a bore of the component. The spherical bearing comprises an outer race received within the component bore, an inner spherical member mounted for rotation within the outer race and a releasable retaining element for releasably retaining the outer race in the component bore. The outer race and the component comprise interengaging indexing formations whereby said outer race may be mounted within said component bore in a plurality of angular positions relative to the longitudinal axis (A) of the component bore.Type: GrantFiled: April 1, 2016Date of Patent: May 1, 2018Assignee: GOODRICH ACTUATION SYSTEMS SASInventors: Arnauld R. E. Hervieux, Gregory Y. Meignat

Patent number: 9958014Abstract: A coupling (1) for a shaft-end (2) having a square cross-section includes a front plate (6), a locking plate (7) and a rear plate (8) provided with square openings (9, 10, 11), in which the square shaft-end can be inserted. The locking plate can be rotated back and forth between an unlocked position (I), in which the square openings in the front plate, the rear plate and the locking plate coincide, and a locked position (II), in which the openings do not coincide. In the unlocked position the square shaft-end can be inserted through the coinciding square openings. Subsequently, the locking plate is rotated so that the shaft-end cannot be pulled out until the locking plate is returned into the unlocked position. The coupling can be used for easily interconnecting different types of parts, for example, applicable with exercise bicycles, bicycles, etc.Type: GrantFiled: December 2, 2013Date of Patent: May 1, 2018Assignee: Theodorus Cornelius Antonius SmetsInventor: Theodorus Cornelius Antonius Smets

Patent number: 9958015Abstract: A rolling-element telescoping shaft assembly for connecting a driveshaft and transmitting a torque includes an outer shaft member extending along a longitudinal axis and defines an interior bore and inner surface. An inner shaft member is at least partially disposed within the bore and telescopically moveable relative thereto along the axis and defines an outer surface. Rolling-element outer grooves are arranged in the inner surface, distributed around the axis, and functional (i.e., used for transmitting a torque). Outer recesses are defined between the outer grooves and define a shorter distance between adjacent torque-transmitting outer grooves. Rolling-element inner grooves are defined on the outer surface and distributed around the axis. Rolling elements are rollingly arranged in the outer and inner grooves and rollingly engage the outer and inner shaft members during telescoping movement of the shaft assembly to reduce friction therebetween.Type: GrantFiled: September 26, 2014Date of Patent: May 1, 2018Assignee: STEERING SOLUTIONS IP HOLDING CORPORATIONInventors: Eduardo Mondragon, William P.

Patent number: 9958017Abstract: A metering device for controlling an oil delivery rate for a wet-running clutch. The wet-running clutch has at least one pair of interacting friction surfaces and an actuation unit for actuating the wet-running clutch. The actuation unit has an axially supported support disk and an axially displaceable thrust disk, wherein the thrust disk and the support disk are rotatable relative to one another. The metering device has a first component which is connected fixedly with respect to a housing, and a second component which is connected to the thrust disk in a rotationally conjoint and axially relatively displaceable manner.Type: GrantFiled: March 24, 2014Date of Patent: May 1, 2018Assignee: Magna Powertrain AG & Co KGInventor: Stefan Leitgeb
