Dongguan City, Xu-feng Hardware Products Factory is a professional manufacturer of metal springs, lathe parts and stamping parts of the enterprise, the factory has advanced technology and equipment, modern factories and professionals torsion spring, selling products around the world. Shaft driven by a foot, so that the shaft can scroll spring return? Flat spiral spring, also known winding spring having one end fixed and the other end of the torque acts; material under the torque of the spring bending elastic deformation shaped springs, the spring is twisted in a plane, the deformation angle and torque to size proportional. According to Baidu description Ann spring, should be able to make the shaft back position, but there is a limit to the Games axis. But with the specific installation methods and applications related. You should think of people who have experience in the design of mechanical ask. . Dongguan City, Xu-feng Hardware Products Factory is a professional production of metal springs, lathe parts and stamping parts of the enterprise, the factory has advanced technology and equipment, modern workshops and professional personnel, products sold around the world. Disc spring washer disc spring washer also 名贝勒维尔 spring washers, inventor Frenchman Belleville. DIN6796 disc spring washers (HDS series) is designed for connecting bolts and screws lock washer. It is designed and manufactured according to DIN 6796, for medium or high strength bolts, screw connection. Large load bearing and elastic recovery makes HDS series is very effective, bolt tension can withstand relaxation due to the following causes: wear wearing parts, creep, relaxation, thermal expansion, contraction, or seal compression. HDS series elastic effect of the screw increases several times, it can effectively replace batteries ordinary spring washer spring, but not used as a lock washer, flat washer. Because HDS series can be combined or superimposed on the disc springs. Involution combinations can increase the amount of deformation of the disc spring group, the spring force increases the disc spring combinations composite group. Ideal installation is flattened as possible, closer pressed flat, Zhang torque increase sooner, without a torque wrench, you can get the proper bolt tension.
