摘要： A thrust needle roller bearing and a method for manufacturing the bearing with improved lubricant circulating ability, reduced drilling abrasion of the cage, and improved durability of the bearing has a plurality of needle rollers and two annular cages. Each of the cages is formed with a plurality of pockets. Each pocket has a radial length longer than the height of the roller. The two annular cages hold the needle rollers by sandwiching them between the cages within roller holding portions formed in the pockets. The radial length of each of the roller holding portions of the cages is formed shorter than the height of the roller. The two cages are assembled by folding them as a unit so that both the portions of the unit on either radially outer and inner side of the roller holding portions have their axial thickness smaller than that of the roller holding portions. The two cages are secured to one another at both their radially outermost and innermost end portions.

摘要： The present invention is to suppress wear of outer diameter surfaces of chain guiding rollers (41) in a chain guide and extend the life. Respective shaft ends of a plurality of roller shafts (31) are supported by pairs of facing side plate portions (22) of guide bases (21) arranged to face each other in a one-side part of a timing chain (5) for transmitting torque. Each of the rollers (41) formed by a plurality of chain guiding roller bearings is rotatably supported by each of the plurality of roller shafts (31). Rollers whose surface hardness is greater than surface hardness of the timing chain (5) by 4 points or more of Rockwell hardness are used as the rollers (41), so as to prevent earlier wear of the outer diameter surfaces of the rollers (41) due to contact with the timing chain (5).

摘要： A timing chain (5) is looped over a driving sprocket (2) attached to a crankshaft (1) and driven sprockets (4) attached to camshafts (3). A pivotable chain guide (A1) having a plurality of rotatable rollers (41) for guiding movements of the timing chain (5) is provided on one side of the slack side of the timing chain (5). Adjustment force of a chain tensioner is applied to a remote end of the chain guide remote from the center of pivoting movement of the chain guide, thereby pressing the rollers (41) against the timing chain (5). The ratio (D1/D2) between the pitch circle diameter D1 of the driving sprocket (2) and the outer diameter D2 of the rollers (41) is determined within the range of 5/3 to 5/1. This prevents insufficient lubrication of the chain guiding rollers (41), makes it easy to lay out the engine.
