摘要： A slip coupling for a work machine includes a main clutch in the form of a friction-based and spring-operated slip clutch. The slip coupling further includes an auxiliary clutch configured to maintain a pre-set spring-induced clamping force on friction plates of the slip clutch, when the slip coupling rotates in a forward direction, and further configured to be able to increase the spring-induced clamping force, when the slip coupling rotates in a reverse rotational direction. The increase of the clamping force is enabled by the fact that one of two auxiliary clutch parts is axially movable when the slip coupling rotates in the reverse rotational direction, the axial movement actuating an increase in pre-tension of mechanical spring or springs of the slip clutch. A work machine such as a combine harvester equipped with the slip coupling is also described.

摘要： An aviation actuator assembly for various aviation servo and/or autopilot applications can include an actuator having an output shaft and a mechanical fuse for joining to the output shaft and another rotating body. The mechanical fuse can include a fuse body having a first connection point for joining to the output shaft, a second connection point for joining to the rotating body, and at least one channel defined in the fuse body. The first connection point and the second connection point are configured to be disposed in a line generally parallel to a common axis of rotation of the output shaft and the rotating body. The fuse body has a generally flat cross-sectional profile along its length between the first connection point and the second connection point, and the channel extends generally perpendicular to the length of the fuse body and narrows the cross-sectional profile.

摘要： A coupling comprising a driven part and a driving part that is connected by a safety pin so as to drive the driven part together with the driving part in a travel direction, one of the parts having a male portion engaged in a female portion of the other part, the male and female portions respectively having a first guide surface and a second guide surface facing each other in such a manner that, in the event of the pin breaking, the driving part is capable of moving relative to the driven part in the travel direction, the pin extending perpendicularly to said direction through corresponding holes made in the male and female portions, the coupling being characterized in that the hole made in the male portion opens out in the bottom of a setback in the second guide surface.

摘要： A power transmission device includes a pulley constituting a driving-side rotor, an inner hub, a washer and a limiter which constitute a driven-side rotor, and a plate configured as a linking elastic member that connects the driving-side rotor and the driven-side rotor. A flat spring that elastically deforms in a direction along a rotation shaft is adopted as the plate. A distance in an axial direction between a pulley-side attachment portion of the plate which is attached to the pulley and a hub-side attachment portion of the plate which is attached to the inner hub is adjusted to fall within a predetermined standard range by interposing a shim as an adjustment member between the plate and the pulley.

摘要： The invention relates to a method for connecting in rotation an output member (5) of an electric motor (1) and an element (2) that is to be driven in rotation, comprising the use of at least one fusible pin (11) that links the output member and the element that is to be driven, and that has at least one section that is prone to fail in shear when a torque transmitted by the fusible pin exceeds a predetermined threshold. The method comprises the step of interposing, between the pin and either the output member or the element that is to be driven, at least one elastic member (20) comprising a first travel with a first stiffness followed by a second travel with a second stiffness greater than the first stiffness.

摘要： An Agricultural baler having a flywheel that is driven via a drive shaft. The flywheel is connected to a pressing component of the baler via a central shaft, wherein the flywheel is mounted over the central shaft via bearings. Further mounted on the central shaft is a shear pin flange which is connected via a shear pin to the flywheel for the purpose of transmitting a rotation movement of the flywheel to the central shaft, wherein the flywheel is held over the central shaft via first fixing component and wherein the shear pin flange is connected to the central shaft via second fixing component.

摘要： A torque-limiting device for secure transmission of a rotation between an inlet baseplate and an outlet baseplate, including at least one drive bolt that forms a breaking element by shearing in case of a torque exceeding a predetermined threshold, and an intermediate baseplate that is driven by the inlet baseplate and which in turn drives the outlet baseplate. The at least one bolt ensures driving of the intermediate baseplate and the inlet baseplate or the outlet baseplate. The intermediate baseplate includes at least one locking element by shape cooperation with a locking part of the bolt, and the torque-limiting device has a larger number of locking elements than of bolts. An agricultural machine can include such a torque-limiting device.

摘要： A shearing mechanism in which a male component mates into a female component, the male component having a first groove extending around the male component and the female component having a second groove extending around the female component, the first groove and the second groove cooperating when the male component is inserted into the female component to define an annular recess. A shearing component is provided within the annular recess, the shearing component having a shear load that is controlled by the material and size of the shearing component. An opening is provided within one or both of the male component and female component, the opening being aligned with the annular recess. Stress relief is provided.

摘要： In a power transmission device for a vehicle, a boss portion of a clutch guide, which is an input-side rotation member of a clutch unit, includes: a spline portion spline-connected to a small-diameter portion at one end of a center shaft which is an input shaft; and a fitting portion that extends further from the spline portion in an axial direction to contact the outer circumference of a medium-diameter portion of the center shaft. A recess functioning as a torque fuse is formed in the medium-diameter portion of the center shaft corresponding to the fitting portion. When the center shaft is severed or disconnected at the recess, the medium-diameter portion of the severed cut center shaft can still remain within the fitting portion, so that appropriate centering can be secured and stable self-propulsion of the vehicle can be secured without unwanted misalignment of the axis of rotation of the clutch.
