Five performance index of detecting oil seal spring
Published：2014.08.11 News Sources：kaichuang spring machinery Views：
Oil seal spring refers to an annular spring seal on the unfolded length, usually up to 20-5000mm, is generally made of wire diameter 0.15-1.0mm between the high quality carbon steel or stainless steel wire winded, its role is to seal card on the shaft, the sealing property is better. Oil seal spring is usually used in the shock absorber to seal or rotating seal, can strengthen the radial force, and can play the role of compensation; when the oil seal used for a period of time after abrasion, oil seal spring will have to compensate radial force.
Five performance indexes of oil seal spring:
1, length tolerance requirements: ± (wire diameter x 1.5);
2, wire diameter tolerance requirements: ± 0.01mm;
3, the winding diameter tolerance requirements: ± 0.05mm;
4, tensile strength requirements: connecting and fixing both ends of the spring, can resist the super length 10% elongation;
5, appearance requirements: no oxidation or contamination of spring surface traces; in the external force is very weak, the spring tie do not form a "8" shape; spring coil wound on the surface does not appear like ups and downs.
Oil seal spring has the advantages of labor saving and tensile elastic, strong good sealing and supporting characteristics better, the applicable fields have food machinery industry, hardware and rubber industry, locomotive, machinery and machine parts.
Application of oil seal spring in production is very extensive, and 8 electrical machine as the oil seal spring machine to use a lot of processing factory is considered, because of its fast speed forming, high accuracy and low cost, by numerous customers friends of all ages, from this kind of meaning is to power 8 machine called the oil seal spring machine. Because the electric 8 machine is the smallest type of computer spring machine, machine performance and quality and different manufacturers spring machine production is not a price, there are also differences.
