  • Patent number: 10440883
    Abstract: A mower with a cutter bar including an elongated hollow casing, at least one bearing block mounted at the level of an orifice of the upper wall of the casing, at least one disk integral with a support shaft mounted in the bearing block, at least one cutter fixed with the ability to rotate freely on the disk, wherein each bearing block is made integral with the casing by at least one fastener assembly composed of at least two fastening elements assembled mutually by screwing. The mower wherein, for each fastener assembly, at least part of the zone or zones of engagement of the respectively female-threaded and male-threaded parts of the fastening elements is situated between the respective mutually opposite bracing surfaces of the fastening elements. Thus the fastening elements are less protruding and their connection zones are not subjected to the aggressions of the outside environment.

  • Patent number: 9759268
    Abstract: 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.

    Abstract: 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 driving the outlet baseplate. The bolt ensures driving of the intermediate baseplate and the inlet baseplate or the outlet baseplate. The intermediate baseplate includes a locking element by shape cooperation with a locking part of the bolt. The intermediate baseplate is formed by two plates pressed against one another, one of which is used for housing of the locking part of the bolt and the other of which is used for axial support of the locking part and housing of the screw rod. An agricultural machine can include such a device.
