Service HotlineGears, 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.
Stainless steel rivet nuts are used on rail passenger cars, highway passenger cars, and ship parking. The main function is the non-structural bearing bolt connection. The main advantage of stainless steel rivet nuts is that there is no operating space on the back of the substrate, and the quality is extremely light. Today, the editor will talk about the selection principles of stainless steel rivet nuts and their uses: 1. The mechanical properties of stainless steel rivet nut materials, especially the strength requirements; Corrosion resistance requirements of materials;
Below in conjunction with the accompanying drawings, Guangdong Yueluo Hardware Industry Co., Ltd. is described in further detail. Please refer to FIG. 2 and FIG. 3, a locking nut includes a nut 1, the bottom is circular, the middle is hexagonal, the top is circular, there is a bolt hole in the center, and the side wall of the bolt hole is threaded. A number of flattening notches 2 are arranged on the top of the nut. According to the locking nut of the preferred embodiment of Guangdong Yueluo Hardware Industry Co., Ltd., the number of the flattening notches 2 is three. Due to the above features, the three flattening gaps can be used as the focal point of the tightening tool and the clamping place of the anti-loose gasket bayonet, and the structure is simple and can be formed by die stamping at one time. The above disclosure is only a preferred embodiment of Guangdong Yueluo Hardware Industry Co., Ltd., and does not limit itself. Any person skilled in the art, without violating the spirit of the present invention, can think of changes that fall within the scope of It is within the protection scope of Guangdong Yueluo Hardware Industry Co., Ltd.
Since the HDS series is a disc spring that can be folded or overlapped. The combination of the butt joint can increase the deformation of the disc spring group, and the combination of the overlapping method can increase the spring force of the disc spring group. The ideal installation method is to flatten as much as possible. The closer it is to the flattened state, the faster the tension torque increases, and the proper bolt tension can be obtained without a torque wrench.
The spring self-locking nut is a spring clip self-locking nut, which consists of an S-shaped spring clip and a self-locking nut. The S-shaped spring clip is provided with a fixing hole (3) for fixing the self-locking nut, which is used for the transition through the bolt. The self-locking nut is placed between the clamping hole and the transition hole (4), and is clamped in the clamping hole. The utility model adopts the elastic force of the spring clip to fix the self-locking nut on the connecting plate or the support. Not only is it convenient to install, but also has good reliability after installation.
