HL type elastic pin coupling

   Description of elastic pin coupling column:

    The elastic pin coupling has multiple pins made of non-metallic materials (such as nylon), which are placed in the holes of the two halves of the coupling to realize the connection of the two shafts.

   HL type elastic pin coupling detailed description:

    HL type elastic pin coupling has been listed as standard GB5014-85, which is suitable for all kinds of transmission shafts that mechanically connect two coaxial lines, and is usually used for frequent high and low speed movements.
    The working temperature is -20～+80℃; the nominal torque of transmission is 40～20000N.m.

    The HL type elastic pin coupling has a relatively large structure, simple and reasonable, convenient maintenance, symmetrical and interchangeable on both sides, long life, allowing large axial movement, and has the properties of cushioning, shock absorption, and wear resistance.

    There are cylindrical (Y), conical (Z) and short cylindrical (J) shaft hole types for the elastic pin coupling.The shaft hole and keyway are processed according to the standard GB3852-83 "Coupling shaft column and keyway form and size".
    The main body of the elastic pin coupling adopts precision casting, cast iron HT20-40, cast steel ZG35Ⅱ, the shaft hole and keyway are made of drawing, and the elastic pin is made of MC nylon b.
    It has the ability of micro-compensation for the offset of the two axes, and the elastic parts are sheared when working, and the working reliability is extremely poor. It is only suitable for the medium-speed transmission shaft system with very low requirements, and is not suitable for the working conditions with high working reliability.

   Technical characteristics of elastic pin coupling:

    The elastic pin coupling is a pin made of a number of 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 coupling has a simple structure and is manufactured It is easy 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 selected from nylon 6, which has the ability to slightly compensate for the deviation of the two axes. The elastic part is sheared when working, and its working reliability is extremely poor. It is only suitable for the medium-speed transmission shaft system with very low requirements. It is suitable for working conditions with high reliability requirements. For example, the transmission shaft system of the lifting mechanism of hoisting machinery must not be selected. It is not suitable for low-speed and heavy-duty transmission shaft systems with strong impact and large vibration. Drive shafts with large angular deviations and low installation accuracy should not be used, and they are obsolete.

    The pin in the elastic pin coupling is in a shearing and squeezing state when working, and its strength condition is to calculate the shear strength of the cross section of the elastic pin and the squeeze strength of the pin and the pin hole wall.
