20090052824 | DEVICE ON A DRAFTING SYSTEM OF A DRAW FRAME FOR TEXTILE FIBRE SLIVERS - In a device on a drafting system for textile fibre slivers with weighting of the upper rolls of the drafting system which comprises roll pairs arranged one behind the other, the pairs having lower and upper rolls, the rotating journals at the ends of the upper roll are mounted by means of bearing elements and the bearing elements each have at least one rolling-element bearing having an immovable outer housing (outer ring) and an internal rotational body (inner ring). In order to provide a structurally simple way in which the bearing housings can be mounted on or removed from the presser roll in a simple, quick and reliable manner, the bearing elements are in the form of rolling-element bearings and there is a coupling between the journal and the rotational body. | 02-26-2009 |
20090097793 | RADIAL ROLLING BEARING, IN PARTICULAR SINGLE-ROW SPHERICAL-ROLLER BEARING - The radial rolling bearing has an outer bearing ring, an inner bearing ring, and spherical rollers arranged between bearing rings. The spherical rollers have two flat side faces arranged parallel to one another. The spherical rollers are retained with uniform spacing to one another in the peripheral direction by a bearing cage. The spherical rollers have a width between their side faces of approximately 70% of the diameter of their spherical basic shape. The running faces of the rollers roll in two groove-shaped raceways which are formed in the inner side of the outer bearing ring and in the outer side of the inner bearing ring. At least one of the axial rims which delimit the groove-shaped raceways is reduced in radial height such that the radial bearing can be equipped with an increased number of spherical rollers in an axial assembly process. | 04-16-2009 |
20090180724 | RADIAL ANTI-FRICTION BEARING, IN PARTICULAR, A SINGLE-ROW SPHERICAL ROLLER BEARING - A radial anti friction bearing ( | 07-16-2009 |
20110311173 | Rolling bearing - The present invention provides a rolling bearing which is excellent in high-temperatures and high-speed durability and quietness, is capable of effectively preventing hydrogen brittleness-caused peeling from occurring on a rolling surface thereof, and has a low environmental load. A rolling bearing ( | 12-22-2011 |
20110311174 | BALL ROLLER BEARING, IN PARTICULAR FOR ABSORBING COMBINED RADIAL AND AXIAL LOADS - A ball roller bearing, which has an outer and inner bearing ring with a groove-shaped raceways and ball rollers, which roll between the hearing rings in the raceways. The rollers are held at distances from each other in the circumferential direction by a hearing cage and which have a width that is dimensioned larger than the radial distance between the inside and the outside of the bearing rings. The raceways are divided into two segments by an axially centered annular groove such that a first ball roller rolls on two first diagonally opposed track segments and a second ball roller rolls on two second diagonally opposed track segments of the bearing rings. Both bearing rings are single-piece components, and the bearing cage is formed by two identical double prong-type cages acting independently of each other. The bearing is filled with the ball rollers by an axial tilt cam assembly method. | 12-22-2011 |
20150308499 | NOISE REDUCING STRUCTURE OF SPEED REDUCTION DEVICE FOR ELECTRIC CVVT - A noise reducing apparatus of a speed reduction device for electric continuous variable valve timing (CVVT), may include the speed reduction device having an inner tooth portion formed to be faced opposing an external wheel of a ball bearing in an interior diameter surface of a housing that may be integrally formed with a sprocket and rollers arranged through a cage between an inner tooth of the inner tooth portion and the external wheel of the ball bearing, wherein a coating layer may be formed to ease impact in exterior circumference portions of the rollers. | 10-29-2015 |
