At least a portion of the first joint member is drivingly connected to at least a portion of a first shaft and at least a portion of the second joint member is drivingly connected to at least a portion of a second shaft. One or more first joint member tool grooves circumferentially extends along the outer surface of the first joint member. The joint assembly further includes a nut that drivingly connects at least a portion of a third shaft to at least a portion of the second shaft. The nut includes one or more nut tool grooves circumferentially extending along the outer surface of the nut.

Abstract: A constant velocity fixed joint. The center line (M22) of the outer ball tracks (22) towards a first side (S1) departs, radially inwardly, a reference radius centered in the point of intersection between a perpendicular line on tangents (T22) at the center line (M22), and the longitudinal axis (L12). The center line (M23) of the inner ball tracks (23) towards a second side (S2) departs, radially inwardly, a reference radius centered in the point of intersection of a perpendicular line on the tangent at the center line (M23), and the longitudinal axis (L13). In the outer joint part, from the joint center plane (EM) to the second side (S2), the center line (M22) moves beyond the reference radius radially outwardly. In the inner joint part (13), from the joint center plane (EM) to the first side (S1), the center line (M23) moves beyond the reference radius, radially outwardly.

Abstract: A constant velocity joint includes a first rotation body and a second rotation body. The first rotation body includes a cup unit, a shaft, and ribs that project from the cup unit and connect the cup unit to the shaft. One of the first rotation body and the second rotation body transmits a rotational driving force to other one of the first rotation body and the second rotation body through balls. The first rotation body is so formed that the cup unit and the shaft are formed into one piece using resin material. Moreover, the rib is so formed into one piece with the cup unit and the shaft using resin material.

Abstract: A constant velocity joint includes an outer member defining an interior opening and a plurality comprising at least four grooves disposed within the interior opening and extending along a first longitudinal axis with each of the grooves being parallel to the other grooves and the first longitudinal axis, and an inner member disposed within the interior opening having a second longitudinal axis and defining a plurality of pockets corresponding to the grooves disposed radially about the second longitudinal axis with each of the plurality of pockets opposing one of the plurality of grooves. The joint further includes a plurality of drive balls corresponding to the grooves, each drive ball having a spherical shape and rotatably disposed within one of the plurality of pockets and moveably disposed within one of the plurality of grooves, wherein the outer member, inner member and plurality of drive balls comprise a constant velocity joint.

Abstract: A shaft member (72) includes a plurality of shaft splines (166) and a shaft preloading portion (170). The assembly also includes a collar member (80) adjustably coupled to the shaft member and having a collar member groove (214) and a preloading portion formed (226) therein; a first member (126) having a first member groove (242)and a plurality of first member splines (238) formed therein; and a retaining member (122) selectively at least partially interposed within both the collar member groove and the first member groove for restraining axial movement between the shaft member and the collar member. At least a portion of the first member groove and at least a portion of the collar member groove are selectively aligned when the shaft member is at least partially interposed within the first member to permit the retaining member to be at least partially positioned within both the first member groove and the collar member groove.

Abstract: A process for assembling to a knuckle member a bearing unit for driving wheels including a hub, a bearing, and a constant velocity universal joint is simplified. In order to achieve this, a hub (10) and an outer joint member (31) of an out-board side constant velocity universal joint (30) are plastically joined together. An outer peripheral surface (26a) of an outer member (26) is press-fitted into an inner peripheral surface of the knuckle member, and a maximum diameter dimension (D1) of the out-board side constant velocity universal joint (30) is set smaller than a minimum diameter dimension (Dn) of the knuckle member (6). Also, a maximum diameter dimension (D2) of an in-board side constant velocity universal joint (40) is set smaller than the minimum diameter dimension (Dn) of the knuckle member (6).

Abstract: A support system for the mounting/suspension/elevation of a commercial projector is disclosed. The projector support grasps the projector to be mounted at one of its surfaces (typically, the bottom surface) through the use of two support arms. The support arms are affixed to the projector surface though mounting screws or other equivalent fastening mechanisms. The support arms each feature an adjustment slot which runs substantially the entire length of the arms. The presence of the two slotted arms allows for a countless array of scissoring arrangements for the support arms. This allows for interconnection with/mounting of the vast majority of commercial projectors (which invariably feature differing constellations of mounting holes). The projector support also employs a primary mount to facilitate swiveling/positioning of the projector so that the unit is effectually oriented for projection.

Abstract: A non-stroking constant velocity universal joint including an inner joint member, an outer joint member, and a plurality of torque transferring bearing spheres in facing pairs of ball grooves in the inner and outer joint members. The bearing spheres are maintained in a common plane bisecting the angle of articulation between the inner and outer joint members by a cage consisting of a pair of hollow hemispherical segments (“hemi-segments”) clamped radially against each other by the outer joint member. Interlocking lugs and notches on the hemi-segments prevent relative linear translation therebetween. The hemi-segments are made from flat blanks which are perforated for the cage windows and then plastically deformed to the shape of the hemi-segments. The cage is assembled around the inner joint member and may, therefore, have dimensions which reduce unit stresses in the cage and preclude assembly of the inner joint member into the cage through a circular open end of the cage.

Abstract: In a constant-velocity universal joint, the rotary motion to be transmitted from the driving shaft to the driven shaft through the medium of rotary members disposed between the opposed lateral contact surfaces of the adjacent yokes of the driving shaft and the driven shaft is made to act on the rotary members in the tangential direction of the pitch circle of the rotary members when the lateral contact surfaces of the adjacent yokes are formed parallel to the normal axes, thereby enabling the rotary motion to be transmitted with high efficiency without entailing any loss due to occurrence of resultant force. The retainer for holding in position the rotary members can be positively kept in the plane perpendicular to the bisector of the intersecting angle of the axes of the two shafts when the surfaces formed in the retainer for guiding the yokes are curved, thereby allowing the constancy of the angular-velocity of transmission of the rotary motion to be secured.

Abstract: A universal joint has two shafts, axially restrained, but pivotable from a common point. One shaft end is in the form of a thick-walled hollow sphere. Two axially extending grooves are cut into the wall facing each other in a circumferentially opposed relationship to form a first set. The other shaft end is in the form of a spherical bowl having a central ball. The inside surface of the bowl and the surface of the ball define an annular spherical cavity into which the hollow sphere nests. Two axially extending grooves are cut, one in each surface, in a radially opposed relationship to form a second set. Each set of grooves positively determines the line path that the center of an enclosed ball will travel. In the assembled joint, the line paths are in mirror image relationship and always intersect in the homokinetic plane. The ball, being enclosed by each set is forced to occupy the intersection. The number of balls used can be any number, odd or even.
