摘要： A fixed type constant velocity universal joint prevents heat generation when a high load is applied or during high-speed rotation to improve durability, and suppresses a contact resistance between a cage and inner and outer races to improve constant velocity performance. Curvature centers of track grooves of outer and inner joint members have an offset of 0 in an axial direction. Track grooves of the outer and inner joint members, which are tilted in opposite directions from each other with respect to an axis line, are alternately formed in a circumferential direction. An outer surface of the inner joint member is a spherical surface to be brought into sliding contact with an inner spherical surface of the cage. An inner surface of the outer joint member is a cylindrical surface.

摘要： A tripod type constant velocity universal joint comprises an outer joint member having three track grooves with roller-guiding surfaces opposing each other circumferentially, a tripod member with three trunnions protruding in a radial direction, a plurality of rollers each inserted into a corresponding track groove and a plurality of rings each fitted on the corresponding trunnion for supporting the roller rotatably. An outer surface of the trunnion is formed to take on a straight shape in a longitudinal section and an ellipse shape in a cross-section. A contact ellipse shape between the trunnion and the ring is modified so as to render the radius of curvature r smaller while keeping an aspect ratio b/a stable in comparison with a contact ellipse shape being defined to minimize contact pressure between a ring inner surface and a trunnion outer surface.

摘要： The tripod member has three trunnions which are projected radially. Each of the trunnions carries a roller, and this roller is accommodated in one of the track grooves in the outer joint member. The outer peripheries of the rollers and the roller guideways make angular contact with each other. Support rings are fitted onto the outer peripheries of the trunnions. These support rings and the rollers are assembled (unitized) via a plurality of needle rollers to constitute roller assemblies capable of relative rotations. In longitudinal sections, the outer peripheries of the trunnions have straight shapes parallel to the axes of the trunnions. In cross sections, the outer peripheries are elliptic in shape, with their respective major axes perpendicular to the axis of the joint. The inner peripheries of the support rings have arcuate convex sections.

摘要： In a no-flange type outer joint member, the amount of abrasion in a large inner diameter portion formed for a track groove is intended to be restrained. In a tripod type constant velocity universal joint including: a no-flange type outer joint member; and a roller assembly including a roller, being attached to a trunnion so as to be capable of oscillating, hardened layers are formed on portions of a large inner diameter portion of the outer joint member, which are in contact with an inclined roller assembly. In this case, a value of F/D is set equal to or less than 0.45, where a distance from a center of the track groove of the outer joint member to the ends of both the hardened layers on the side of the center of the track groove is F, and a diameter of an outer circumference of the roller assembly is D.

摘要： In a lamp for an automobile in which the front opening edge of a lamp housing is covered with front lenses or outer lenses to form lamp chambers for accommodating therein bulbs serving as light sources. An inner lens is provided inside the front lenses or the outer lenses, and a diffusion reflection layer fabricated by roughening processing or the like is formed particularly on a part of an outer peripheral surface of a flange portion of the inner lens or the entire outer peripheral surface thereof. Light emitted by the bulb is irregularly reflected by the diffusion/reflection layer so as to prevent a portion higher in brightness than other portion from appearing in the light emitting planes of the front lenses or the outer lenses.
