20150143948 | Cam Follower Device - The cam follower roller device comprises a body | 05-28-2015 |
20150143947 | CAM FOLLOWER ROLLER DEVICE - The cam follower roller device comprises a body, a shaft mounted on the body, a roller mounted on the shaft and able to rotate, and a plain bearing interposed radially between the shaft and the roller. An outer surface and/or an inner surface of the plain bearing comprise a plurality of cavities. The ratio of the sum of the surfaces areas of the cavities to the total surface area of the outer surface, or of the inner surface, in which the cavities are formed is between 2% and 40%. The cavities have a depth between 0.5 μm and 5 μm. | 05-28-2015 |
20150141185 | PULLEY DEVICE FOR A CHAIN OR BELT AND MOTOR VEHICLE EQUIPPED WITH SUCH A DEVICE - The inventive pulley device for one of a chain and belt provides an inner ring, an outer ring, at least one row of rolling elements mounted in a rolling chamber defined between the inner ring and the outer ring, a pulley secured in rotation with the outer ring and provided with an outer radial surface for engagement with one of a chain and a belt. A screw for mounting on a support is housed radially inside the inner ring and a mounting support element is provided with a passage opening for the screw. The opening is tapped, with a complementary tapping of a thread arranged on the screw, the screw is provided with a groove, offset relative to the thread along a longitudinal axis (X40) of the screw and in which the tapping of the opening is received. | 05-21-2015 |
20150139584 | BEARING ASSEMBLY - A bearing assembly includes first and second rolling-element bearings each having an inner ring with a running surface for rolling elements and a guide flange that extends radially outwardly beyond the running surface for limiting axial movement of the rolling elements. The inner rings are configured such that they are in contact with each other exclusively within a contact surface diameter that is smaller than an average value of a maximum diameter of the running surface of one of the inner rings and a maximum outer diameter of that inner ring. The guide flanges are disposed on sides of the inner ring of the first rolling-element bearing and of the second rolling-element bearing that face each other axially. | 05-21-2015 |
20150139583 | BEARING UNIT FOR FLUID MACHINERY APPLICATION - A bearing unit for a fluid machinery application having a double-row bearing, the double-row bearing comprising: a first angular self-aligning contact bearing arranged next to a second angular self-aligning contact bearing for locating and rotatably support a shaft; each angular self-aligning contact bearing having a respective set of rolling elements formed of rollers arranged in a row and interposed between an associated curved inner raceway and a curved outer raceway. Each roller is a symmetrical cylindrically shaped roller having a curved raceway-contacting surface engaging with the curved inner and outer raceways. Each roller is inclined in relation to the axial direction of the shaft by a respective first or second contact angle. The rollers are arranged to cooperate with the associated curved inner and raceways for supporting an axial force and a radial force. Examples of fluid machinery applications include: wind turbine, water turbine or propulsion turbine arrangements. | 05-21-2015 |
20150125104 | BEARING ARRANGEMENT FOR FLUID MACHINERY APPLICATION - A bearing arrangement for a fluid machinery application employing an axially locating bearing. The axially locating bearing includes: a first angular self-aligning contact bearing arranged next to a second angular self-aligning contact bearing. Each of the first angular self-aligning contact bearing and the second angular self-aligning contact bearing includes a set of rolling elements arranged in a row and interposed between a respective curved inner raceway and an associated curved outer raceway. Each roller is a symmetrical cylindrically-shaped roller having a curved raceway-contacting surface. Each roller is inclined respective to the axial direction of the shaft by a respective contact angle. The rollers support an axial force and a radial force. The axially non-locating bearing position is arranged spaced apart from the axially locating bearing position, as seen in the axial direction. Examples of fluid machinery applications include: a wind turbine, water turbine or a propulsion turbine. | 05-07-2015 |
20150125103 | PULLEY-BEARING ASSEMBLY - A pulley-bearing assembly provided with a pulley and a rolling bearing confined by respective coupling surfaces co-axial to each other and defining a groove there between; the rolling bearing being provided with two rows of rolling bodies having pitch diameters (D, Di) of different size, and a metallic ring being pressed into the groove and deformed so as to join the pulley with the bearing. | 05-07-2015 |
