HL-type elastic pin coupling has been listed as the national standard GB5014-85, for a variety of mechanical coupling two coaxial axis of the drive shaft, usually used for moving high and low speed movement. Working temperature of -20 ~ +80 ℃; transmission nominal torque of 40 ~ 20000N.m.

Flexible pin coupling has a large structure is simple, reasonable, easy maintenance, symmetrical interchangeable, long life, allowing a larger axial movement, with a buffer, shock absorption, wear and other properties.

    Shaft hole type has cylindrical (Y), conical (Z) and short cylindrical (J). Shaft hole and keyway according to the national standard GB3852-83 "coupling shaft and keyway form and size" of the provisions of processing. Semi-coupling with precision casting, cast iron HT20-40, cast steel ZG35 Ⅱ, shaft hole and keyway with drawing, the pin made of MC nylon b made.

The elastic pin coupling is made of a number of non-metallic elastic material made of the pin, placed in the half of the coupling flange hole, through the pin to achieve the coupling of two halves, the coupling structure is simple and easy Manufacturing, installation and replacement of flexible components more convenient, do not move the two halves coupling. The material of the elastic element (pin) is generally made of nylon, which has the ability to compensate for the offset of the two axes. The elastic part is cut and the working reliability is very poor. It is only applicable to the medium speed transmission shaft which is very low. In the work of high reliability requirements of the working conditions.
