Optimized design of pin coupling to enhance function

来源:日期:2020/6/8 9:42:26

  The pin coupling is a pin made of several non-metallic elastic materials, which is placed in the flange hole of the two halves of the coupling, and the two halves of the coupling are connected by the pin. The structure of the pin coupling is simple and easy It is more convenient to manufacture, assemble, disassemble and replace the elastic element, without moving the two couplings.The material of the elastic element (column pin) is generally selected from nylon, which has the ability to compensate the deviation of the two axes in a small amount. The elastic part is sheared when working. It is only suitable for the medium-speed transmission shaft system with very low requirements and higher requirements.

  The pin in the pin coupling shaft is in shearing and squeezing state when working, and its strength condition is to calculate the shear strength of the elastic pin cross section and the squeezing strength of the pin and the pin hole wall.Since the selected material of the pin coupling is cast iron, its weight is 38.8 kg, so that the motor wastes a lot of electric energy during the water supply operation, which affects the efficiency of the unit and increases the operating cost.
