A clutch assembly includes a journal bracket having a center shaft, a drive feature rotatably supported on the center shaft of the journal bracket and configured to accept a torque input to the clutch assembly, a clutch pack that is controllable to selectively transmit torque between an input and an output, a housing attached to the clutch pack that includes a stub shaft, a removable connection engaged between the drive feature and the stub shaft such that torque is transmittable through the removable connection during operation of the clutch assembly, and one or more perpendicular engagement features on the stub shaft configured to accept a tool to engage and disengage the removable connection. At least one of the perpendicular engagement features is exposed to line-of-sight access from a location substantially perpendicular to an axis of rotation of the clutch pack.

A clamping hub includes a body and an aperture, defined by the body, configured to receive a shaft. The clamping hub also includes a clamp configured to secure the shaft in the aperture. the clamp includes a first deformable component that defines a first portion of the aperture and configured to, when deformed, change a size of the aperture and a second deformable component that defines a second portion of the aperture opposite from the first portion of the aperture and configured to, when deformed, change the size of the aperture.

A charging device for the heat treatment of workpieces being provided with a hub, comprising a charging support, a shaft and at least one auxiliary hub, wherein the workpiece can be vertically supported on the shaft by auxiliary hub(s) precisely fitted into the hub, and the shaft being supported by the charging support as well as use of auxiliary hubs for the dimensionally stable hardening of gear-wheels in vertical position.

A method includes disposing a first shaft and a second shaft in an end to end arrangement, positioning a sleeve over the end to end arrangement, coupling the sleeve to the first shaft via a first set of fasteners extending through a first set of radial holes in the sleeve and into the first shaft, coupling the sleeve to the second shaft via a second set of fasteners extending through a second set of radial holes in the sleeve and into the second shaft, and allowing the sleeve to self adjust the alignment between the first shaft and the second shaft while transmitting torsional, translational, or torsional and translational loading through the first set of fasteners and the second set of fasteners.

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.

A flywheel coupling assembly for transmitting torque between a shaft and a flywheel includes a clamp ring assembly and a flywheel attachment flange assembly. The clamp ring assembly includes a first clamp ring adapted to be coupled to the shaft, a second clamp ring coupled to a coupling hub of the flywheel attachment flange assembly, and an elastomeric center element coupling the first and second clamp rings. A planer plate element of the flywheel attachment flange assembly is adapted to be coupled with the flywheel. Also disclosed are a method of forming a flywheel coupling assembly and a method of coupling a flywheel to a shaft.

A coupler for operatively interconnecting an externally splined power take off (PTO) shaft of a prime mover and a driveline of an implement that is configured to be driven by the prime mover so as to operate the implement comprises a smooth bore arranged to receive the splined PTO shaft and at least one spline-forming member which is movable in a radial direction relative to the bore between a working position for mating with a respective spline of the PTO shaft and a retracted position in which the spline-forming member is free of mating engagement with the splined shaft. There is also provided at least one locking member which is radially movable in a similar fashion to the spline-forming member between matingly-engaging and non-matingly engaging positions relative to a circumferential groove in the PTO shaft. The locking member is coincident with the spline-forming member circumferentially of the bore.

A coupling includes a shaft at least partially inserted into a hollow shaft and a ring part, in particular of a clamping ring, slipped onto the hollow shaft. The ring part is axially restricted by a collar provided on the shaft, in particular a radially projecting collar, and/or the ring part is resting against a collar, or the collar, of the shaft, in particular against a collar provided on the shaft, in particular a radially projecting collar. The hollow shaft has slots, in particular axial slots, which are set apart from the collar. The ring part has a chamfer, in particular on its inner side and/or at its ring opening and/or in particular in its axial end region facing the collar, so that the inner diameter of the ring part in the axial region covered by the chamfer is greater than the inner diameter in the particular axial region in which the ring part is in contact with the hollow shaft. The ring part has a radially uninterrupted threaded bore into which a screw part, in particular a set screw and/or a threaded pin, is screwed, which exerts pressure on the hollow shaft.

Embodiments of clamping hub are disclosed. In one embodiment, the clamping hub includes a non-circular aperture with a portion of the non-circular aperture being formed so as to be substantially flat. The clamping hub also includes a shaft securer aperture that is formed in a substantially flat wall that contributes to the substantially flat portion of the non-circular aperture.

A clamping connection includes a hollow shaft region, a shaft at least partially introduced into the hollow shaft region, a screw, and a clamping ring. The hollow shaft region has an axial slot radially extending through the hollow shaft region. The screw has a screw thread and a screw head, which is larger than the largest diameter of the screw thread. The hollow shaft region has a flattening, the screw rests at least partially against the flattening, and the screw is set apart from the shaft.
