The thrust roller bearing cage (11) includes: a first cylindrical portion (36) extending in a direction of a rotation axis (12); a first disc portion (31) continuous with the first cylindrical portion (36) and extending in a radially outward direction; and a second cylindrical portion (37) continuous with the first disc portion (31) and extending in the direction of the rotation axis (12). The first cylindrical portion (36), the first disc portion (31), and the second cylindrical portion (37) are formed in an area located radially inside the pockets (21). The first disc portion (31) has a through hole (53).
THRUST ROLLER BEARING CAGE AND METHOD FOR MANUFACTURING THE SAME
A thrust roller bearing cage (11) of the present invention is included in a thrust roller bearing (20) and includes a plurality of pockets (21) accommodating rollers (13). The thrust roller bearing cage (11) includes: a first cylindrical portion (36) extending in a direction of a rotation axis (12); a first disc portion (31) continuous with the first cylindrical portion (36) and extending in a radially outward direction; and a second cylindrical portion (37) continuous with the first disc portion (31) and extending in the direction of the rotation axis (12). The first cylindrical portion (36), the first disc portion (31), and the second cylindrical portion (37) are formed in an area located radially inside the pockets (21). The height (H36) of the first cylindrical portion (36) in the direction of the rotation axis is smaller than the height (H37) of the second cylindrical portion (37) in the direction of the rotation axis.
THRUST ROLLER BEARING CAGE AND METHOD FOR MANUFACTURING THE SAME
A thrust roller bearing cage (11) of the present invention is included in a thrust roller bearing (20) and includes a plurality of pockets (21) accommodating rollers (13). The thrust roller bearing cage (11) includes: a radially outer area bent portion (41) formed by bending an area located radially outside the pockets (21) inward in a radial direction; and projecting portions (44) that are formed in a tip end of the radially outer area bent portion (41) at positions aligned with the pockets (21) and project inward in the radial direction beyond radially outer edges of the pockets (21) so as to contact end faces (16) of the rollers (13) accommodated in the pockets (21). The projecting portions (44) have a width that is or more and or less of the width of the pockets (21).
THRUST ROLLER BEARING CAGE AND METHOD FOR MANUFACTURING THE SAME
A thrust roller bearing cage (11) of the present invention is included in a thrust roller bearing (20) and includes a plurality of pockets (21) accommodating rollers (13). The thrust roller bearing cage (11) includes: a radially outer area bent portion (41) formed by bending the cage (11) inward in a radial direction along an annular groove formed at a position radially outside the pockets (21); and projecting portions (44) that are formed in a tip end of the radially outer area bent portion (41) at positions aligned with the pockets (21) and project inward in the radial direction beyond radially outer edges of the pockets (21) so as to contact end faces (16) of the rollers (13) accommodated in the pockets (21). A trace (29) of the groove is left at a position along which the cage is bent.
THRUST ROLLER BEARING CAGE AND METHOD FOR MANUFACTURING THE SAME
A thrust roller bearing cage (11) of the present invention is included in a thrust roller bearing (20) and includes a plurality of pockets (21) accommodating rollers (13). The thrust roller bearing cage (11) includes: a radially outer area bent portion (41) formed by bending an area located radially outside the pockets (21) inward in a radial direction to a tilt angle of less than 45; and projecting portions (44) that are formed in a tip end of the radially outer area bent portion (41) at positions aligned with the pockets (21) and project inward in the radial direction beyond radially outer edges of the pockets (21) so as to contact end faces (16) of the rollers (13) accommodated in the pockets (21).
TWO LIP SEAL
A seal for a bearing assembly, including: a longitudinal axis; a first portion arranged to engage an outer ring for the bearing assembly; and a second portion extending radially inward and in a first axial direction from the first portion. The second portion includes: a first lip arranged to contact a rotatable shaft passing through the bearing assembly; and a second lip located past the first lip in a second axial direction, opposite the first axial direction, and arranged to be separated, in a radial direction, from the rotatable shaft by a first distance.
Method and apparatus for broadcasting scan patterns in a scan-based integrated circuit
A broadcaster, system, and method for reducing test data volume and test application time in an ATE (automatic test equipment) in a scan-based integrated circuit. The scan-based integrated circuit contains multiple scan chains, each scan chain comprising multiple scan cells coupled in series. The broadcaster is a combinational logic network coupled to an optional virtual scan controller and an optional scan connector. The virtual scan controller controls the operation of the broadcaster. The system transmits virtual scan patterns stored in the ATE and generates broadcast scan patterns through the broadcaster for testing manufacturing faults in the scan-based integrated circuit. The number of scan chains that can be supported by the ATE is significantly increased. Methods are further proposed to reorder scan cells in selected scan chains, to generate the broadcast scan patterns and virtual scan patterns, and to synthesize the broadcaster and a compactor in the scan-based integrated circuit.
Axial needle roller bearing with self-aligning washers
An axial needle roller bearing assembly is provided having first and second axial end washers, each with a radial body having a concave outer profile and a convex inner profile in radial cross-section and each including an axial flange on one of a radially inner or outer side. First and second intermediate washers having respective intermediate radial bodies with first and second axial sides are provided with the first axial sides defining first and second bearing races and the second axial sides defining contact surfaces for the respective first and second axial end washers. A cage and roller assembly is located between the first and second bearing races, and includes a cage with a plurality of radially extending needle roller pockets, and a plurality of needle rollers received in at least some of the pockets.
