Service HotlineSprinkle the excess flat washer 6 on the positioning plate II3-1 on the flat washer positioning plate 3, and shake the flat washer positioning plate 3 by hand. After a short time, the flat washer 6 will be positioned and arranged on the upper positioning plate II3-1. In the flat washer hole 3-7, since the width of the opening groove 113-32 of the baffle plate II3-3 is smaller than the diameter of the flat washer hole 3-7, and the thickness of the upper positioning plate II3-1 is designed according to the thickness of the flat washer 6, each Only one flat washer 6 can be accommodated in the flat washer holes 3-7 of each upper positioning plate II3-1, and then use a brush to remove the excess flat washer
Gears, mechanical components with teeth on the rim that can continuously mesh to transmit motion and power, are mechanical parts with teeth that can mesh with each other. The gears used in industry are generally made of steel. The commonly used steels are quenched and tempered steel, hardened steel, carburized and quenched steel and nitrided steel. The strength of cast steel is slightly lower than that of forged steel, and it is often used in Larger-sized gears; gray cast iron has poor mechanical properties and can be used in light-load open gear transmissions; ductile iron can partially replace steel gears; plastic gears are mostly used in places where light loads and low noise are required, and are matched with them The gears are generally made of steel gears with good thermal conductivity.
Lock washers feature easy installation. 1. Just place the helical tooth surfaces on the inner side of the two washers against each other and place them between the nut and the connecting material; 2. After the nut is tightened, the radially convex surface on the outer side of the lock washer and the contact surfaces at both ends are in an engaged state, and The angle of the slope angle of the helical tooth surface on the inner side of the washer is greater than the thread angle of the bolt; 3. When the bolt is elongated due to mechanical vibration, the nut will rotate and loosen accordingly. Because the frictional force of the outer radial convex surface of the lock washer is greater than the frictional force between the inner helical tooth surfaces. In this state, only the relative dislocation between the inner helical tooth surfaces is allowed to generate a certain lifting tension; 4. When the bolt shrinks, the helical tooth surface of the washer will make the nut return to its original position. So as to achieve 100% anti-loose and tightening effect; 5. Washers are suitable for relatively flat and smooth surfaces; 6. If the connecting material is non-metallic material, a metal plate can be fixed on the connecting material, so that the Use the lock washer; 7. There is no need to use a torque wrench when installing the lock washer; 8. You can choose to use an air tool when installing or removing the lock washer.
Yueluo also provides a thin plate rivet structure, which includes a metal thin plate and a rivet. The metal sheet is provided with a riveting hole; the riveting piece is penetrated in the riveting hole, the outer edge of the riveting piece is provided with an occlusal structure, and the inner edge of the riveting hole is embedded with the occlusal structure. A deformation groove is provided on the metal sheet, and the deformation groove is adjacent to the rivet hole.
The research on rivet nuts started in the 1970s in my country and is still in the design and development stage. In the mid-1980s, equipment for the production of blind rivets was introduced from abroad, but no rivet nut has been produced so far. After the inventor's search, no low-carbon steel rivet nut was found to be publicly used.
