摘要： A rotor adapter for connection between a drive shaft having eccentric motion and a driven shaft having circular motion within a downhole mud motor. The rotor adapter has two symmetrical ends on either end of a rotor adapter shaft. Each end includes a coupler defining a socket for receiving one end of the rotor adapter shaft. A thrust ball is located between the rotor adapter shaft and the coupler and seated in pockets that have radii larger than the thrust ball and depths shallower than the radius of the thrust ball. Circumferentially spaced pockets around the rotor adapter shaft near the end of the shaft fit steel balls which protrude into complementary pockets on the coupler. The coupler pockets are cylindrical and plugged from the outside with plugs. The plugs are secured in place with the steel balls in the complementary pockets. The pockets on the rotor adapter shaft are elongated in the axial direction of the rotor adapter shaft to allow tilting of the rotor adapter shaft. The coupler and rotor adapter shaft ends are oppositely tapered away from the pockets to alow for tilting of the rotor adapter shaft.

摘要： A constant velocity universal joint for transmitting driving torque between rotative members, including an outer race member with an axial annular recess therethrough, the annular recess in the outer race member being enlarged at one end to accommodate an inner race member that has a bulbous end with a plurality of radially aligned circumferentially spaced bores positioned in the bulbous end. The inner race member also has an axially positioned bore in the bulbous end. A pin is positioned in the bore within the bulbous end and a plurality of spherical balls are positioned in the bores so that each spherical ball rests against the outer surface of the pin. The inner race member and the spherical balls telescope into the outer race member and are restrained from axial separation by a restraining ring seated in the outer race member.

摘要： A universal joint of the type utilizing spherical roller balls to transmit torque or power between an inner joint member and an outer joint member. The balls roll in a recess in the inner joint member and each ball rolls in a rectilinear recess in the outer joint member, with such rolling action permitting and resulting from the articulation of the joint. Each recess in the outer joint member has at least a major portion that has a radial extent, from the central axis of the joint, that follows a curvilinear configuration to provide a maximum radial extent when the inner and outer joint members are aligned, through a gradually reducing radial extent as the joint is articulated, in order to provide a substantial constant depth of penetration of each ball into its outer joint member recess throughout the range of articulation of the joint. This helps to maintain the elements of the joint in contact with one another over a relatively wide range of joint articulation, to maintain free-play transmission of torque between the inner joint member and the outer joint member over this range of articulation. The joint also has complemental spherical surfaces on abutting portions of the inner and outer joint members to permit them to articulate at right angles to the axis of articulation through the outer joint recesses and to sustain end or compressive loads applied to the inner and outer joint members. The joint has particular utility as a two-ball joint in an automotive tilt-steering system.

摘要： A ball type universal joint construction where a ball member is rotatably received in a housing and a bearing structure interposed therebetween in a manner which limits the relative rotational degrees of freedom. The ball member has a spherical surface portion which includes axially extending bearing receiving slots and the housing has a cavity spherical surface portion which includes bearing receiving recesses in registry with the receiving slots. Ball type bearings disposed partially within the recesses and partially within the slots limit movement between the ball member and the housing to articulated movement relative to each other. The housing also includes an access opening at one end face having an enlargement through which the ball member can be passed when rotated 90 degrees to its nominal, functioning position. This allows the ball member to be inserted into the housing through the enlargement while at the same time accommodating passage of the bearings into the housing recesses. Thereafter, the ball member is further rotated such that the receiving slots also partially receive the bearings and thus capture the ball member in an articulating, non-rotatable relationship in the housing.

摘要： In an angularly movable universal joint, a ring of balls extends around the axis of rotation of the joint with the balls being radially movably supported in bores in the inner joint member and guided within grooves in the outer joint member. Adjacent balls are in contact with one another through intercommunicating openings between adjacent bores. The area of the material of the inner joint member in a plane extending perpendicularly of the axis of rotation and including the centers of the balls is greater than zero but less than the maximum area of the cross section remaining when the rectangular area of the bores plus areas defined between the inner ends of the rectangular areas of the bores and a circular arc having a radius of the bores is removed.
