Structure of HL Type Nylon Elastic Pin Coupling Elastic pin coupling has a relatively simple and reasonable structure, convenient maintenance, two sides are symmetrical and interchangeable, long life, allows large axial movement, and has the properties of buffering, shock absorption and stable performance.Get more news about Elastic Pin Coupling Wholesaler,you can vist our website! Axis hole types are cylindrical (Y), conical (Z) and short cylindrical (J). The shaft hole and keyway are processed according to the national standard GB3852-83 "Coupling shaft column and keyway form and size". The coupling half is made of fine casting, cast iron HT20-40, cast steel ZG35Ⅱ, the shaft hole and keyway are drawn, and the column pin is made of MC nylon b. The elastic pin coupling is a pin made of non-metallic elastic material, which is placed in the flange holes of the two halves of the coupling, and the two halves of the coupling are connected through the pin. The structure of the coupling is simple. It is easy to manufacture, and it is more convenient to assemble, disassemble and replace the elastic element without moving the two halves of the coupling. The material of the elastic element (column pin) is generally nylon, which has the ability to compensate the offset of the two axes in a small amount. The elastic element is sheared during operation, and the work quality is relatively poor. It is only suitable for medium-speed transmission shafts with very low requirements, and is not applicable. It is suitable for working conditions with high requirements for work excellence. LZ High Quality Elastic Pin Gear Coupling uses nylon rod to turn the column pin into the opposite hole between the two half coupling and the outer ring inner surface, and transfers the torque through the column pin to realize the connection between two half couplings. It has certain shaft offset compensation ability and shock absorption performance. LZ High Quality Elastic Pin Gear Coupling is symmetrical and interchangeable, long life, allowing large axial movement, and has the performance of cushioning, damping, wear resistance and so on. The shaft holes of the two axle head of the pin type coupling of the LZ elastic column are all straight holes.
