摘要:
A needle roller bearing (21) as a roller bearing comprises an outer ring (22) having a plurality of outer ring members (22a) and (22b) split by a split line extending in the axial direction of the bearing, and a plurality of needle rollers (23) arranged along the track surface of the outer ring (22). The outer ring member (22a) is in the form of a semicircular shape having a center angle of 180° and has an engagement click (22c) bent from one circumferential side end to the radial outer side. The two outer ring members (22a) and (22b) are connected in the circumferential direction to form the annular outer ring (22).

A roller bearing includes an outer ring formed by connecting a plurality of arc-shaped outer ring members in a circumferential direction and a plurality of rollers arranged along an inner diameter surface of the outer ring. A slope surface (22i) is provided at one or each circumferential end on an inner diameter surface of the outer ring member (22a), and a contour line of the slope surface (22i) is along a direction perpendicular to a revolution direction of the roller.

A needle bearing (11), comprising an outer ring (13) having a plurality of outer ring members (12) divided by a parting line extending in the axial direction of the bearing, a plurality of needle rollers (14) rollingly disposed on the raceway surface of the outer ring (13), and a retainer (15) holding the intervals of the needle rollers (14). Each of the outer ring members (12) comprises a projection (12a) as a positioning engagement part for positioning the outer ring (13) on a housing at a position displaced from the circumferential center part of its outer peripheral surface and an engagement claw (12b) projecting from the axial end part of the outer ring member (12) to the radial inner side to restrict the axial movement of the retainer (15).

A needle roller bearing has an outer ring (13) having a split section in the circumferential direction, rollers (14) rollable along the inner circumferential surface of the outer ring (13), and a retainer (15) for retaining the rollers (14). The outer ring (13) has an engagement claw (12b) projecting radially inward at an end in the width direction of the outer ring and restricting the movement in the axial direction of the retainer (15).
摘要:
A roller bearing comprises an outer ring formed by continuously arranging circular arc-shaped outer ring members in the circumferential direction and rollers disposed along the inner diameter surface of the outer ring. A slope surface (22i) is formed on the inner diameter surface of the outer ring member (22a) at at least one end in the circumferential direction, and the contour line of the slope surface (22i) is directed in the direction orthogonal to the revolution direction of the rollers.

A needle roller bearing (21) as a roller bearing comprises an outer ring (22) formed by connecting a plurality of arc-shaped outer ring members in a circumferential direction, and a plurality of needle rollers (23) arranged along the inner diameter surface of the outer ring (22), and an oil groove (22i) extending in a circumferential direction so as to contain a position opposed to an opening (13e) of an oil path of a housing is formed in the outer diameter surface of the outer ring member.
摘要:
A needle roller bearing comprises an outer ring having a plurality of outer ring members split by split lines extending in an axial direction of the bearing, a plurality of needle rollers arranged on an orbit surface of said outer ring so that they can roll thereon, and a cage holding the needle rollers at intervals. The outer ring member has a projection serving as a positioning engaging part which engages with a housing for positioning, and an engaging click protruding from an axial end of the outer ring member inward along a diameter to prevent the cage from moving in an axial direction, in positions shifted from its circumferential center.

摘要:
A variable stroke characteristic engine in which a piston (11) and a crankshaft (30) are linked to a control shaft (65) via a variable stroke link mechanism (LV), and the variable stroke link mechanism (LV) is operated by a hydraulic actuator (AC) that drives the control shaft (65) to thus make the stroke travel of the piston (11) variable, in which the hydraulic actuator (AC) is formed from a housing (HU), a cover member covering an aperture of the housing (HU), a vane case provided integrally within the housing (HU), and a vane shaft (66) housed within the vane case, and the vane shaft (66) is formed integrally with the control shaft (65). The number of components of the actuator (AC) can be decreased, and its ease of assembly can be improved.
