A drive hub includes a body and lugs that extend radially from the body and are engageable with a primemover of a primary power source. The lugs have a fastening lug that includes a radially extending bore. A hybrid, single piece setscrew extends within the bore and has a hemispherical portion configured to apply pressure to engage the drive hub to a shaft of a secondary power source.

An electrical submersible well pump assembly has shaft couplings. One of the couplings has a lower hub that rotates in unison with the motor shaft and an upper hub that rotates in unison with the pump shaft. A helical spring clutch engages both hubs when the motor shaft is being driven by the motor. Ceasing driving rotation of the motor shaft causes the spring clutch to disengage from the upper hub, enabling the pump shaft to rotate the upper hub without rotating the lower hub.

The Shaft Spring Cutch is an apparatus, used to drive fasteners, or the like, that is multi-directional, and non-ratcheting, comprised of two drive members, separated and held in an unengaged position by a return spring, that are axially retained within a guide housing. The first drive member is attached to a handle or input shaft. The second drive member is attached to a drive bit. When in an unengaged position, the handle, or input shaft, can rotate freely in either direction relative to the drive bit. The first and second drive members are engaged by applying axial force sufficient to overcome the return spring force, which locks the handle, or input shaft, and drive bit together. Once engaged, any rotational force applied to the handle, or input shaft, is transferred to the drive bit. Optionally, the apparatus may be locked together for continuous drive bit engagement using a locking mechanism and a fastener can be placed directly on the drive bit, then using a feature of the tool, the fastener can be spun by hand until set.

A shaft connection 1 for a longitudinal shaft assembly, has at least a first shaft having a first and second ends, and a second shaft, disposed so as to be coaxial with the first shaft, having first and second ends; the shafts extending axially. The first end forms a hollow portion. The first shaft end forms a first journal having a displacement portion. The first shaft end at least in an initial position of the shaft connection extends through the hollow portion which axially by the displacement portion forms a guide portion and circumferentially forms a form-fitting first connection. In the initial position a mutual axial displacement of the first and second shafts is prevented by an axial securing feature. In a crash the axial securing feature; is releasable by an axial release force. The first shaft is axially displaceable relative to the second shaft.

A universal joint assembly includes a yoke including a serration hole to receive an end portion of a steering column and a bolt-hole to receive a bolt which is used to restrict the steering column received in the serration hole, and a misassembly prevention member coupled to the yoke and elastically movable from a first position in which the bolt-hole is at least partially blocked to a second position in which the bolt-hole is opened, thereby preventing a misassembly of the steering column and improving safety and reliability of the universal joint assembly.

A torque transmitting system, a drive unit, and a drive assembly are provided. The torque transmitting system includes a torque transmitting element and a support element which supports it via rotary bearings. The torque transmitting element has a first connection device for coupling to a first assembly in a rotationally fixed manner and a second connection device for coupling to a second assembly. One of the two elements forms a substantially hollow cylindrical shoulder, and the respective other element forms the outer cylindrical face and, correspondingly thereto, the inner face of a hollow cylinder radially outwards. The shoulder is arranged between the outer face and the inner face in a radial direction. A first rotary bearing is arranged between the outer face and the shoulder, and a second rotary bearing is arranged between the shoulder and the inner face. By using the torque transmitting system, less axial installation space is.

A torque transmitting assembly including a first drum having a plurality of teeth formed at an end thereof and a sensor component annularly extending on an inner surface of the first drum. A gear assembly axially aligns with the first drum and has a plurality of teeth intermeshing with the plurality of teeth of the drum. The gear assembly includes an annular gear and a plate axially aligning with the gear.

A joint assembly includes a first member having splines formed therein. A second member includes splines formed thereon and is coupled to the first member. The splines of the first member engage the splines of the second member. An access window is formed on the first member. A ring retains the first member to the second member. A seal extends across a joint between the first member and the second member and covers the access window. A portion of the ring is accessible through the access window following removal of the seal, where the ring can be manipulated to release the first member from the second member.

The present invention relates to a method for the profile generation of involute-based toothed shaft connections, comprising: determination of a circle described by the reference diameter d.sub.B′, distance-based generation of the shaft top circle using the reference diameter distance A.sub.dB, the shaft top circle being the quasi first element of the shaft profile; distance-based generation the hub top circle using the effective touching height h.sub.w, distance-based determination of the touching point between the shaft tooth flank and the shaft root fillet using the shaft form oversize of the reference profile C.sub.FP1 or the shaft form oversize C.sub.FP1 generation of the shaft root fillet, the shaft reference profile being already completely generated by means of this step in the case of full filleting of the shaft; constant-tangent generation of the shaft root circle for shaft root filleting, this step being required only in the case of partial filleting; and obtainment of the shaft profile.

The present invention relates to a measuring device with a magnetic field sensor for detecting at least one operating parameter of an agricultural joint shaft for torque transmission between a power take-off shaft of a towing vehicle and a transmission of an agricultural appliance, which includes at least one journal cross, to the opposing journals of which a shaft body is connected, and a protective tube rotatably accommodating the shaft body therein, wherein the magnetic field sensor is adapted to measure a magnetic field emanating from the bare shaft body of the joint shaft.
