flange hole of the two half couplings, through the column pin connection of the two half couplings, the structure of the coupling is simple, easy to manufacture, assembly, disassembly and replacement of elastic components is more convenient, there is no need to move the two couplings.Column elastic element (pin) is generally selected material nylon 6, there are two axis offset trace compensation ability, flexible work under shear, work reliability is poor and is only applicable to medium speed transmission shafting with low requirements, does not apply to the operation condition of the high reliability requirements, such as lifting machinery lifting gear transmission shafting is absolutely cannot choose, should not be used for low-speed bearing and has strong shock and vibration transmission shafting, for larger radial and angular deviation condition and installation precision of low transmission shafting nor should choose, eliminate varieties. The strength condition is to calculate the shear strength on the cross section of the elastic column pin and the extrusion strength between the column pin and the pin hole wall.Direction for use1. Stress in the elastic column pin coupling: due to the difference in internal and external heating of the metal, the expansion is not uniform, resulting in internal stress, which is called thermal stress. If the annealing temperature is too high and lead to graphite section, it will not easily cut and make the quenching overheating and deformation. Decarburization makes the workpiece surface appear soft point, reduce the surface hardness, wear resistance and fatigue strength.2. Flexible column pin coupling beryllium oxide.3.Elastic column pin coupling hard and brittle mesh carbide.4. Decarburization of elastic column pin coupling: decarburization refers to the phenomenon that all or part of the carbon on the steel surface is burned off.
Matters needing attention
1, the elastic column pin coupling is nylon rod for the elastic element, the elastic sleeve pin coupling is rubber or polyurethane for the elastic element, the effect is not the same2. The elastic sleeve column pin has no noise, the elastic column pin has some noise, and the transmitted torque is not the same.3, the elastic column pin is more commonly used, the transfer torque is larger, the elastic sleeve column pin effect is better, but the elastic sleeve is vulnerable parts.StructureSize InformationPacking&ShippingAfter Sales ServiceCustomer service onlineThe company adheres to the service standard of "all-round, high quality and fast speed" and takes customer satisfaction as thegoal.Company IntroductionChangyuan in Henan Province is located on the mother river of the Chinese people – the Yellow River.
