Spray Boom For An Agricultural Machine
The present invention is directed to a spray boom for an agricultural machine in which the boom is arranged as a truss with interior diagonal struts of the truss being configured to absorb tension and compression energy imparted by deflections over the length of the boom with such energy being dissipated as heat. In one aspect, the diagonal strut could comprise a rod moveable with respect to a tube with a polymer, such as an elastomeric material, arranged in the tube to dampen the movement. The tension and compression of the diagonal strut could subject the dampener to a shearing force which could be absorbed by the dampener rather than transferred to the machine.
IMPROVED INERTIAL UNIT WITH SUSPENDED INERTIAL DEVICE
Equipment including an inertial detector device provided with fastener studs enabling the inertial device to be fastened to a support frame. At least one of the fastener studs has two elements, one of which elements is fastened to the support frame and has a bearing surface that is in contact with a bearing surface of the support frame. The other element is fastened to the inertial device and has a bearing surface that is in contact with a bearing surface of the inertial device, which two elements are suspended relative to each other by means of a body made of elastically deformable material. At least one of the elements is fastened by at least one screw. The corresponding bearing surfaces is provided respectively with a centering portion and with a housing for receiving said centering portion with a fit that allows clearance of no more than 50 m.
Tuned Mass Absorber Assembly and System for Attenuating Frequency Specific Vibrational Energy
A tuned mass absorber assembly comprises a mass structure, and a flexure system comprising first and second flexure sections (e.g., cross bar flexures) supported by, and extending in opposing directions from, the mass structure. The flexure system can comprise flexure section mounts situated at distal ends of the first and second flexure sections, respectively, and that are operable to mount the tuned mass absorber assembly to a structure subject to induced vibrations therein. A mass of the mass structure and a stiffness of the flexure system can be tuned to attenuate vibrations at a specific input frequency generated in response to induced vibrations of the structure. A system can comprise a vibration isolator attached to a chassis (e.g., of an airplane), and supporting a payload (sensors(s)) and isolating the payload from vibrations. A tuned mass absorber assembly can be mounted to the vibration isolator for attenuating vibrations at a specific input frequency that may affect the payload.
BEARING BUSH
A bearing bush includes a core, an intermediate sleeve surrounding the core in a manner extending in a circumferential direction, an outer sleeve surrounding the intermediate sleeve in a manner extending in the circumferential direction, an elastomer body disposed between the intermediate sleeve and the outer sleeve, and a stop device. In embodiments, at axial ends of the core, the stop device protrudes from the core in a radial direction and limits a movement of the intermediate sleeve in an axial direction. The intermediate sleeve is mounted on the core and, relative to the stop device, in a circumferentially rotatable manner. The outer sleeve has several projections. The intermediate sleeve has at least one counter-projection which overlaps in the radial direction with the projections for limiting the axial deflection of the outer sleeve relative to the core.
