HL type-elastic pin coupling

HL type-elasticPin couplingThe basic type is composed of the same two halves of the coupling, nylon pins, baffles and bolts.The pin is inserted into the pin holes on the flanges of the two coupling halves, and the direction in which it is inserted into the holes of the half coupling is alternately changed.A baffle is fixed on the side of the half coupling.

This coupling is suitable for all kinds of transmission shafts that mechanically connect two coaxial lines, and is usually used for frequent high and low speed motions.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, easy to maintain, symmetrical and interchangeable on both sides, long life, allowing large axial movement, and has the properties of cushioning and shock absorption.

The shaft hole types are cylindrical (Y), conical (Z) and short cylindrical (J).The shaft hole and keyway are processed according to the standard GB3852-97 "Coupling shaft column and keyway form and size".The semi-coupling is made of casting, cast iron HT20-40, cast steel ZG35Ⅱ, the shaft hole and keyway are made of drawing, and the pin is made of MC nylon.

The HL type-elastic 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 coupling structure It is simple and easy to manufacture, and it is more convenient to assemble and disassemble the elastic element without moving the coupling halves.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, and the working reliability is poor. It is only suitable for the medium-speed transmission shaft system with very low requirements. Working conditions with high reliability requirements.
