20130148919 | ROLLING BEARING AND MANUFACTURING METHOD THEREOF - The present invention provides a rolling bearing which is excellent in strength, rigidity, heat resistance, and dimensional accuracy while being able to hold rolling elements in a stable manner and reduce manufacturing cost without degrading performance as a bearing and a manufacturing method for the rolling bearing. To achieve the object, the present invention adopts a rolling bearing including a cage provided with a plurality of pockets for housing and hold the rolling elements arranged at specific intervals in a circumferential direction in a peripheral wall of a cylindrical member. The cage is formed integrally by metal powder injection molding; and the cage includes a housing space for the rolling elements and a rolling-element fall-out prevention structure is formed by applying compressive working to an outer edge of the housing space in a direction from an outer circumferential surface toward a radial center of the cage. | 06-13-2013 |
20140155209 | CHAIN GUIDE AND CHAIN TRANSMISSION DEVICE - A chain guide includes a plurality of roller shafts provided on one side of a timing chain for torque transmission and spaced from each other in the longitudinal direction of a guide base facing the timing chain. The respective roller shafts rotatably support chain guiding rollers in the form of needle roller bearings. The rollers are cylindrical members having the same diameter over the entire axial direction such that the rollers are movable in the axial direction relative to the timing chain. The rollers are supported so as to be movable in the axial direction. When the rollers and the timing chain move relative to each other in the axial direction and the rollers move relative to the roller shafts in the axial direction, contact portions between the rollers and the roller shafts are displaced in the axial direction, so that radial loads are not locally applied. | 06-05-2014 |
20140378254 | CHAIN TENSIONER AND CHAIN TRANSMISSION DEVICE - A chain guide is provided which reduces moving resistance of a camshaft-driving, torque-transmitting timing chain. The chain guide includes a guide base ( | 12-25-2014 |
20150013420 | CAM FOLLOWER AND METHOD FOR PRODUCING CAM FOLLOWER - A cam follower is constituted by an outer ring which has an outer track surface in its inner circumference; a stud which has an inner track surface opposed to the outer track surface, a flange portion abutting on one side of the inner track surface, a side plate fitting portion and a mounting shaft portion abutting on another side of the inner track surface in this order, and a fiber flow formed continuously from the flange portion to the inner track surface along their outer circumferences; rolling elements which are arranged between the outer track surface and inner track surface; and an inner side plate which is pressed into the side plate fitting portion to work with the flange portion for limiting axial movement of the outer ring and the rolling elements. | 01-15-2015 |

20150049976 | ROLLING BEARING - An object of the present invention is to prevent abrasion powder from accumulating and stacking in pockets in a retainer of a roller bearing, thereby protecting the rollers from brinelling and loss of lubrication for extended life of the roller bearing. On an inner diameter surface of annular regions in the retainer, cutouts are formed from the retainer's axially outer side end surface toward an inner side. The cutout has an outer diametrical position on a more radially outer position than an outer diametrical end of the inner-side projection of the retainer. This improves an axial flow of lubricant oil from an inner diameter side of the retainer toward the cutout which is formed in the annular region, making it less likely that dust such as metal abrasion powder contained in the lubricant oil will stay at the inner-side projection of the pillar. | 02-19-2015 |
