Service HotlineThe side gear thrust washer used in the automobile differential is a flat washer, which is installed between the differential housing and the side gear to prevent the side gear from retreating. Due to the high-speed rotation of the side gear when the differential is working, it is necessary to ensure that the contact surfaces on both sides of the flat gasket are well lubricated.
An automatic screw-removing device for automatically removing screws on a workpiece, the automatic screw-removing device comprising a worktable, a manipulator disposed on one side of the worktable, and a screw-removing mechanism installed on the manipulator, The screw-removing mechanism includes an installation plate connected to the manipulator, an electric batch installed on the installation plate, a bit head disposed on one side of the electric batch, and a visual recognition unit disposed on the installation plate , the visual recognition unit takes pictures of the screw to determine the coordinates of the screw, the bit is rotated under the drive of the electric batch to disassemble the screw, the bit is magnetic and can be adsorbed the screw.
The materials of rubber gaskets are usually NBR (nitrile butadiene rubber), SBR (styrene butadiene rubber), HNBR (hydrogenated nitrile butadiene rubber), EPDM (EPDM rubber), SILICONE (silica gel), VITON (fluorine rubber), CR ( Neoprene), FFKM (perfluoroelastomer), etc.
At present, injection molding screws are widely used in various electronic and automotive components, including a body, the middle of which is provided with a through hole 3, the body head 1 has a hexagonal cross-section, and the tail 2 is provided with screw teeth. When in use, the middle through hole 3 of the main body will first put the wire harness, and then fix it by injection molding from the head I, and the threads of the tail 11 should be connected and installed with other components. Because the head I of the main body is hexagonal, the torque provided after injection molding is insufficient. Therefore, after the external thread is installed and connected with other components, the head is prone to slip, the installation is not reliable, and there is no push-pull force, resulting in product failure and increased safety hazards.
The combination screw is actually a kind of screw, but it is special. It is generally a three-component or a two-component, but at least it can be called a combination screw. The main difference from ordinary screws is that they are equipped with one more spring washer or one more flat washer than ordinary screws. This is the main difference between the appearance of combination screws and ordinary screws. In addition to the obvious difference in appearance between combination screws and ordinary screws, the main difference is the difference in mechanical properties and uses. The combination screw is a three-component or two-component with a flat washer. Of course, it is equipped with a flat washer by an ordinary screw. When the spring flat pad is attached, the spring flat pad will not fall off. Fastened to form an assembly. In terms of mechanical performance, the combination screw is composed of three accessories, and in terms of performance, three fasteners must be used together. The mechanical properties of the combined screw are stronger when used. More convenient, the biggest advantage of the combined screw is that the production line can be operated conveniently and quickly, and the work efficiency can be improved. The difference between the use of combination screws and ordinary screws is mainly in the breadth of use. The use of ordinary screws is more extensive than that of combination screws. Basically, ordinary screws are used in industrial products, and combination screws! It is only useful for specific product materials. When the screw needs to be used with a spring washer and a flat washer, the combination screw can be used at this time.
