HL elastic pin coupling is the use of a number of non-metallic elastic materials made of pins, placed in the two halves of the coupling flange hole, through the pin to achieve the two halves of the coupling coupling, the coupling structure is simple, easy to manufacture, easy to install and dismantle replacement of the elastic element, without moving the two halves of the coupling.The material of the elastic element (pin) is nylon, which has the ability to compensate for the offset of two axes, the elastic member is subjected to shear when working, and the workability is only applicable to the medium-speed transmission shaft system with very low requirements, and is not applicable to the workability of the working conditions with higher requirements.
This HL type elastic pin coupling has been listed as standard GB5014-85, applicable to a variety of mechanical coupling two coaxial transmission shaft, usually used for frequent high and low speed movement.The working temperature is from -20 to +80℃; the nominal torque is from 40 to 20000N.m. The coupling can be used in the following applications
HL type elastic pin coupling has a larger structure is simple, reasonable, easy maintenance, two symmetrical interchangeable, long service life, allowing a larger axial fluctuation, cushioning, shock absorption, and other properties.
Shaft hole types are cylindrical (Y), conical (Z) and short cylindrical (J).Shaft holes and keyways are processed according to the provisions of standard GB3852-83 "Coupling Shaft Column and Keyway Forms and Dimensions".Half-couplings are cast, cast iron HT20-40, cast steel ZG35Ⅱ, shaft holes and keyways are drawn to shape, and pins are made of MC nylon b.
