HL Type Elastic Pin Gear Coupling

HL type elastic pin gear coupling has been listed as the standard GB5014-85, which is suitable for various mechanically connecting two coaxial transmission shafts, and is usually used for high and low speed movements with frequent movements. The working temperature is -20～+80℃, the transmission nominal torque is 40～20000N.m.. The elastic pin coupling has a simple and reasonable structure, convenient maintenance, two sides are symmetrical and interchangeable, has a long service life, allows large axial movement, and has the properties of buffering, shock absorption, etc.

The HL type elastic pin gear coupling is a pin made of several non-metallic elastic materials. Placed in the flange holes of the coupling halves The two halves of the coupling are connected by pins,the coupling has a simple structure and is easy to manufacture, and it is convenient to assemble and disassemble the elastic element without moving the two couplings. The material of the elastic element (column pin) is generally nylon 6, which has the ability to compensate for the offset of the two axes in a small amount. The elastic element is sheared during operation and has poor workability. It is only suitable for medium-speed transmission shafts with very low requirements, not suitable for use as working conditions with high performance requirements.

Shaft hole types are cylindrical (Y), conical (Z) and short cylindrical (J). Shaft hole type and key type standard GB3852-83 "coupling shaft column and key type and size" elevation platform. The shaft is made of castings, cast iron HT20-40, cast steel ZG35Ⅱ, the shaft hole and key are made of drawing, and the column pin is made of MC nylon b.
