Diaphragm flexible coupling image is more important, but the quality is fundamental. Coupling image mainly refers to the state of the coupling, such as the surface roughness of the coupling, the appearance of the exposed state, is the painting state, or blackened state or plating state (galvanized or hard chrome plated etc. Of course, the chamfering of the coupling, the arc radius of the shaft shoulder and the flange of the coupling flange, the flange thickness, the number of connecting bolts, etc. are all categorized into the image of the coupling. Is more important, he is not just a good-looking appearance (black treatment can prevent rust, but black treatment is most afraid of the wet environment), but play a major role in the surface protection of the coupling (electroplating can make up for Blackening processing defects).
Diaphragm flexible coupling
Diaphragm elastic coupling quality is a key factor related to the service life and cost of the transmission system. The quality of the coupling includes the design of the coupling structure dimensions, the coupling material and the corresponding heat treatment process, and the coupling. The strength and contact strength of accessories and components, the elastic compensation gap control of elastic couplings, the dimensional accuracy of the inner hole of the coupling, the roughness of the inner hole surface, and the width of the keyway. Only the joint image and the quality of the coupling are good, it is the high-quality coupling product, while the welding of the coupling replaces the cast steel (for example, the brake wheel manufacturing of the brake coupling). Steel instead of forgings (manufactured by two coupling halves of TMG and TMV couplings), low strength of coupling parts (bolt strength grade, strength grade of elastic elements, etc.) and heat treatment process of the corresponding coupling (normalizing, The lack of tempering, tempering, high-frequency quenching, etc.) can only produce a low-quality product. Both form and spirit are indicators of appraiser and various products.
Coupling quality refers to the degree of coupling in the national standard strength indicators, while the slightly-sharp coupling should be similar to the low profile performance. Regardless of whether they are rigid or elastic couplings, there are clear national standards for structural shape and strength performance, and there are many coupling manufacturers in China, and the couplings of various coupling manufacturers are basically the same in shape (Of course, careful observation. There are differences, such as the strength level of the connecting bolts and the number of diameters, etc.) and the strength performance index is the final indicator of the quality of the coupling. However, this index is often the reciprocal operation of the transmission equipment When a little overload occurs, the coupling user realizes the failure mode of the coupling.
The failure mode of high-quality couplings should be that the coupling parts are scrapped, and the strength of the two couplings matches the overall strength of the transmission equipment, while the couplings with a slight quality are often damaged when the coupling parts are damaged. The overall scrapped.
Coupling cost-effective price competition, resulting in some manufacturers cut-shaft manufacturing coupling, for example, the intermediate shaft shaft coupling manufacturing, brake wheel coupling brake wheel manufacturing, the use of ordinary steel and steel pipe welding manufacturing These coupling products can also realize torque transmission when the transmission system works normally, but welding cracking may occur during reciprocating start-stop or a little overload (because of poor welding impact resistance), resulting in coupling. The overall scrapped. Our Yuza Machinery Co., Ltd. manufactures couplings in accordance with the specific conditions of use of the national standards of couplings, and reasonably designs the manufacturing process of the coupling materials and heat treatment (round bars, forgings and casts). The steel form and the corresponding quenching and tempering treatment, etc., abandon the poor welding stability of the common steel manufacturing process, so that the high quality of the coupling allows users of the coupling to feel.
