This utility model relates to the field of civil engineering technology, and in particular to a vibration-damping tenon structure, comprising: two pre-embedded mechanisms, each with an identical structure, including an externally connected mounting plate, a sleeve assembly fixedly connected to the mounting plate, and a pressure plate fixed at the opening of the sleeve assembly, the pressure plate having a through hole; and a vibration-damping mechanism, with both ends passing through the through hole and extending into the sleeve assembly, the ends of the vibration-damping mechanism being bolted to the center of the mounting plate; wherein the vibration-damping tenon has a variable diameter structure, with the largest diameter located inside the sleeve near the pressure plate. This utility model, through the combination of the pre-embedded mechanism and the vibration-damping mechanism, ensures a firm connection between the vibration-damping mechanism and the mounting plate, thereby improving the stability of the overall structure. By maximizing the diameter of the tenon within the sleeve, and optimizing energy dissipation through the special geometry of the internal structure, the durability and reliability of the vibration-damping system are improved, making it more suitable for the high-standard application requirements of modern complex engineering environments.

Method for producing a core layer (13) for a composite component (10) produced in sandwich construction, the method comprising the following steps: - Providing a core layer material (310) as a quasi-endless material at a production plant (300); - rolling out the core layer material (310); - cutting the core layer material (310) into individual elements (320) using a cutting device (330) and / or a cutting punch (332); - making further cuts (340) on the cut elements (320) which later form the corresponding walls of the core layer cells; - wherein the additional cuts (340) result from manufacturing data and a previously carried out optimization of the core layer (13) with regard to stability and weight for adaptation to the prevailing loading conditions in order to thereby specifically vary cell properties of the individual core layer cells; - arranging the cut elements (320) with their cuts (340) one above the other to form an element stack (350), wherein additional spacers or adhesive points (360) are introduced between the individual layers of the elements (320) in order to form the specific geometry and shape of the core layer (13); - Pulling apart the completely manufactured element stack (350), resulting in the core layer (13).

The invention relates to a bearing with a textured particle trap surface on its functional tracks. An important aspect of these bearings for efficient operation is promoting lubricant recirculation. For this purpose, a cage is designed with a special geometry that promotes lubricant recirculation. This, together with a sufficient distribution of recesses in its functional tracks, creates a bearing with a contact surface free of microparticles that negatively impact bearing life.

The utility model discloses an efficient milling cutter with a special groove profile and a relief angle, which comprises a circumferential blade and a chip flute, a plurality of grooves are formed on the side wall of the chip flute, the grooves are distributed along the length direction of the chip flute, the grooves are positioned on the front cutter surface of the circumferential blade, a plurality of tangent planes are formed on the rear cutter surface of the circumferential blade, and the tangent planes are distributed along the length direction of the chip flute. And the tangent plane is distributed along the length direction of the rear cutter surface of the circumferential blade. The utility model has the beneficial effects that the plurality of grooves are formed on the side wall of the chip flute, so that chips are broken, the chips are smoothly discharged, and the metal removal rate is improved. A plurality of tangent planes are formed on the rear cutter surface of the circumferential blade and are distributed along the length direction of the rear cutter surface of the circumferential blade, so that the contact area between the rear cutter surface of the circumferential blade and a part can be conveniently reduced through the tangent planes, the friction force caused by machining is reduced, the heat productivity of the cutter is reduced, and the vibration of the cutter in the cutting process can be reduced; and the requirement of high-speed milling can be met.
