摘要： The outer peripheral surface (32) and the inner spherical peripheral surface (34) of a cage (30) of a double-offset constant velocity universal joint are cut after quenched. More specifically, to finish the outer peripheral surface (32) of the cage (30) made up of a spherical portion (32a) and tapered portions (32b, 32c), the spherical portion (32a) and the tapered portions (32b, 32c) are cut after quenched. Then, the spherical portion (32a) is cut at a cutting speed lower than that for the tapered portions (32b, 32c), thereby providing a better roughness to the cut surface of the spherical portion (32a) than to the cut surface of the tapered portions (32b, 32c).

摘要： The present invention provides a constant velocity universal joint component and a manufacturing method thereof capable of achieving increased strength without significant procedural changes, and that can contribute to size reduction and weight reduction. In the constant velocity universal joint component of the present invention, a sharp-angled portion 15 is formed by machining after cold plastic working is applied. A carburization process is then performed in which surface carbon concentration of 0.45mass% to less than 0.60mass% is obtained. Quenching is then performed. High-frequency induction hardening is subsequently performed.

The constant velocity universal joint is characterized in that the ratio of a ball diameter to an outer ring diameter is 0.21 - 0.25, the ratio of a ball pitch circle diameter to an outer ring outer diameter is 0.64 - 0.68, the contact angle of the ball grooves is 30 - 35°, the contact rate of the ball grooves is 1.02 - 1.08, and the ratio of a cage offset amount to the ball pitch circle diameter is 0.07 to 0.09.

摘要： A constant velocity joint (20) includes an outer member (26) defining a plurality of outer member ball tracks (32, 34) and an inner member (38) defining a plurality of inner member ball tracks (42, 44). The outer member ball tracks (32, 34) and the inner member ball tracks (42, 44) cooperate to define a plurality of uniform funnels (50) having a uniform width (W) along a longitudinal axis (L), and a plurality of diverging funnels (52) having a diverging width (W) along the longitudinal axis (L). A drive ball (48) is disposed within each of the uniform funnels (50) and the diverging funnels (52). A cage (56) is disposed between the outer member (26) and the inner member (38), and defines a plurality of windows (58) with one of the drive balls (48) disposed within each of the windows (58). The diverging funnels (52) urge the drive balls (48) along the longitudinal axis (L) to pre-load the cage (56), while the uniform funnels (50) do not urge the drive balls (48) along the longitudinal axis (L), thereby reducing the amount of heat generated between the cage (56) and the drive balls (48).

摘要： A fixed center constant velocity joint (20) includes a first group of funnels (48) and a second group of funnels (56) arranged radially about a longitudinal axis (L) in alternating relationship. The first group of funnels (48) diverges in a first direction (52) and the second group of funnels (56) diverges in a second direction (60) opposite the first direction (52) along the longitudinal axis (L). The first group of funnels (48) defines a first diverging width (50) increasing in value along the longitudinal axis (L) and the second group of funnels (56) defines a second diverging width (58) increasing in value at a different rate than the first diverging width (50) to bias the joint (20) in one of the first direction (52) and the second direction (60).

摘要： A fixed-center constant velocity joint (20) has a race (22) located concentrically to a rotational first axis (24), and a ring-shaped cage (26) located concentrically to a rotational second axis (27). Both the race and the cage are centered to a common center point lying on the first and second axes regardless of the angular state of the joint. A spherical surface (44) carried by the race radially opposes a spherical face (102) carried by the cage for angular movement with respect to the center point. The surface and face are in close or contacting relationship to prevent telescoping movement with respect to the first and second axes.

摘要： The invention relates to a ball cage for homokinetic joints. The aim of the invention is to produce such ball cages in shorter processing times using a more economic and simpler method. To this end, the ball cage that consists of a blank (1) is configured as a substantially annular spherical segment (2) with window-type ball pockets (4) located along the equator with substantially equator-parallel bearing surfaces (5) that interact with the bearing balls. Substantially annular functional zones (9) are located on the outer ring edges (6) and interact with a joint bell and with substantially annular functional zones (7) that are located on the inner ring zones and that interact with the joint spider. The inventive ball cage is especially characterized in that at least some of the functional zones of the blank are raised vis-à-vis the adjoining surfaces of the ball cage.

摘要： The invention relates to a homocinetic joint (11) which is in the form of a counter track joint. Said joint comprises an outer part (12) which comprises a first longitudinal axis (A12), in addition to a connection side and an opening side which are axially opposed to each other, and which comprises first outer ball tracks (18) and second outer ball tracks (20), an inner part (15) which comprises a second longitudinal axis (A22) and connection means for a shaft (22) for the opening side of the outer part (12) and which comprises first inner ball tracks (19) and second inner ball tracks (21). The first outer ball tracks (18) and the first inner ball tracks (19) together form first track pairs and the second outer ball tracks (20) and the second inner ball tracks (21) together form second track pairs, a torque transmitting ball (171, 172) is placed respectively in the track pairs. A ball cage (16) is arranged between the outer part (12) and the inner part (15) and comprises cage windows (241, 242) which are distributed on the periphery thereof, which respectively house at least one of the balls (171, 172). The opening angle (d1) of the first pair of tracks opens when the joint is pulled on the joint average plane (E) from the opening side to the connection side of the joint outer part (12), and the opening angle (d2) of the second pair of tracks opens when the joint is pulled on the joint average plane (E) from the connection side to the opening side of the joint outer side (12). The track average lines (L18, L19) of the first pair of tracks has an inflection point (T1-2) and the central point angle (ß) on the inflection point (T1-2) in relation to the joint average plane (E) is greater than 4°.
