Common couplings for pumps: elastic pin coupling, diaphragm coupling, claw elastic coupling
Features of elastic pin coupling:
The elastic pin coupling is made of several non-metallic elastic materials, which are placed in the flange holes of the two halves of the coupling, and the coupling between the two halves is realized through the pins. It is more convenient to manufacture, assemble, disassemble and replace the elastic element without moving the two couplings.
The material of the elastic element (pin) is generally made of nylon 6, which has the ability to compensate for the offset of the two axes in a small amount. The elastic part is sheared when working, and the working reliability is extremely poor. It is only suitable for medium-speed transmission shafts with very low requirements. It is suitable for working conditions with high reliability requirements. For example, the transmission shaft of the hoisting mechanism of hoisting machinery must not be selected. It is not suitable for low-speed load-bearing and transmission shafts with strong impact and vibration. The working conditions with large deflection and the transmission shaft system with low installation accuracy should not be selected, which are eliminated varieties. Elastic pin coupling The pin in the shaft is in shear and extrusion state during operation, and its strength condition is to calculate the shear strength on the cross section of the elastic pin and the extrusion strength between the pin and the wall of the pin hole.
The elastic pin coupling (GB5014-85) is suitable for various coaxial transmission systems. It uses the shear strength of the nylon rod to transmit the torque. The nominal torque is 160-160000N.M, and the working temperature is -20℃- 80°C. The structure is simple, it has cushioning and shock absorption performance and certain shaft offset compensation ability, and is suitable for use in environments where noise is not controlled. The allowable compensation amount is 0.15-0.25mm in the radial direction and 0.5° in the angular direction.
The specific models are HL1, HL2, HL3, HL4, HL5, HL6, HL7, HL8, HL9, HL10, HL11, HL12, HL13, HL14. The shaft 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 half coupling adopts precision casting, cast iron HT20-40, cast steel ZG35Ⅱ, the shaft hole and keyway are drawn and formed, and the column pin is made of MC nylon.
