    摘要: A roller bearing retainer (13) includes a pair of annular ring parts (14) and a plurality of column parts (15) each including a column center part (16) provided in an axial center region so as to be positioned relatively on the radial inner side, a pair of column end parts (17) provided in axial end regions so as to be positioned relatively on the radial outer side, and a pair of column sloped parts (18) positioned between the column center part (16) and the pair of column end parts (17), and connecting the pair of ring parts to each other. A thickness of each part of the column center part, the pair of column end parts, and the pair of column sloped parts is smaller than a thickness of a boundary part between the adjacent parts.

    摘要: A needle roller bearing comprises an outer ring having a plurality of outer ring members split by a parting line extending in the axial direction of the bearing, and a plurality of needle rollers rotatably arranged on the raceway surface of the outer ring. Thus, a non-contact length “L” between the outer ring members and the needle roller at an abutment part of the adjacent outer ring members, and an effective length “w” of the needle roller has a relation such that L/w

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