A constant velocity universal joint is assembled as a crown ball meshed within a housing socket for rotation about respective rotational axes. The outside diameter of the crown ball is greater than the inside diameter of the socket. A plurality of channels, equally spaced around the crown ball perimeter are cut into the crown ball surface generally along or parallel with the crown ball drive axis. An arcuate cup is cut into each crown ball channel to confine a respective torque transfer element. A number, corresponding to the number of crown ball channels, of partial cylinder channels are cut into the inside surface of the housing socket. One of opposite side walls for each housing channel is given an arcuate radius corresponding to that of the force transfer elements. Ridges between adjacent crown ball channels mesh with ridges between adjacent housing socket channels. Torque transfer elements confined within said crown ball cups engage the partial cylinder wall of the housing channels to transfer drive forces between the crown ball and socket housing through a departure angle between the respective rotational axes.

A constant velocity joint for use in a prop shaft of an automotive vehicle includes an outer race. The constant velocity joint also includes an inner race arranged within the outer race and a rolling element arranged between the outer race and the inner race. A cage is arranged between the outer race and the inner race such that the cage positions the rolling element therebetween. The constant velocity joint also includes a flange contacting the outer race. A plurality of sleeves are arranged between the constant velocity joint outer race and the flange. A plurality of fasteners will secure the outer race to the flange.

A constant velocity universal joint for use with a propeller shaft which reduces its weight and size as well as facilitates assembling a stub shaft, thereby reducing the number of parts used and improving rotational balance. The universal joint, comprising: an outer ring with a cup-shaped enlarged diameter portion having track grooves formed on an inner peripheral surface and with a hollow reduced diameter portion integrated with the enlarged diameter portion; an inner ring having track grooves formed on an outer peripheral surface; balls, interposed between the track grooves of the inner and outer rings, for transmitting torque; a cage, accommodated in an annular space between the inner and outer rings, for holding the balls. The universal joint makes possible to form a unit provided with a stub shaft, having a shaft portion inserted from an open end portion of the enlarged diameter portion of the outer ring to mate with the inner ring to enable torque transmission and having an enlarged diameter portion on an end portion extending from the shaft portion, and provided with a boot, attached to the open end portion of the enlarged diameter portion of the outer ring and the shaft portion of the stub shaft, for sealing the joint.
摘要:
A constant velocity or homo-kinetic universal joint transferring torque through at least three ball members between inner and outer coupling members and held by a cage in a common plane bisecting the angle between the axes of thecoupling members. The radial dimension of the joint is kept at a minimum and the cage rides on spherical walls of the inner and outer coupling members and has circumferentially spaced, radial lugs increasing the guide surfaces of the cage windows. The cage is positioned normal to the open face of the outer coupling member, pushed into the coupling member, rotated circumferentially to align the lugs to fit into the grooves of the coupling member, and then rotated axially into the plane of the coupling member to hold the coupling members in fixed axial relation.

摘要:
An improved universal ball joint especially adapted to be used in the transmission of high torque, as in oil field use, includes a driving and driven shaft. One of the shafts, which may be the driving shaft includes a spherical ball received in a housing provided in the other shaft, which may be the driven shaft. The opposed surfaces of the ball and housing include axially extending grooves of essentially the same depth and length forming therebetween a plurality of chambers. Each chamber receives a pin which is tapered at each end and which forms the driving connection between the shafts. The shafts and the ball may include a bore for flow of fluid through the assembly, the ball being sealed in the ball chamber by seals to provide a sealed ball chamber which may be filled with lubricant, the ball being seated on a bearing and retained in the chamber by a retainer member which prevents relative axial movement between the shafts. Various forms are described including arrangements for flexible drill strings, reamer/stabilizer combination, mill tool combination and an arrangement for use in converting eccentric rotation to concentric rotation for use in a downhole motor.

A swivel joint for transmitting torque between a drive shaft and a driven shaft includes an outer joint member having an interior cavity connected with one of the shafts and an inner joint member carried within the cavity connected with the other shaft. A first plurality of ball receiving grooves are formed on the interior wall surface of the cavity and a second plurality of ball receiving grooves equal in number to the first plurality are formed on the exterior surface of the inner joint member. A ball is carried between at least one pair of corresponding ball receiving grooves of the first and second plurality of grooves for transmitting torque between the inner and outer joint members. A cage having circumferentially arranged window recesses is positioned between the inner and outer joint members and the balls are retained in the window recesses. A stop face is provided on the inside of the inner joint member and a cooperating bearing surface is provided on the cage for engaging the stop face at predetermined angular displacements of the inner joint member with respect to the outer joint member.
