What are the advantages and disadvantages of elastic pin coupling

Elastic pin coupling is an elastic pin made of non-metallic elastic raw materials according to the size of pin holes in the two-half coupling, which is connected by the flange holes of the two-half coupling.Get more news about Elastic Pin Coupling Wholesaler,you can vist our website!

  It is generally made of polyurethane and nylon with high elasticity and toughness. It has high tensile strength and good toughness, which can play an excellent role in reducing vibration and compensating displacement.

  Elastic pin coupling mainly links two-half coupling through pin, so it is very convenient to install and disassemble in use. It can complete disassembly without moving power machine and mechanical equipment. Although this kind of coupling has the advantages of easy disassembly and maintenance-free, it can bear very little shear force because the non-metallic parts are the original parts of the coupling, so it can not be used in heavy load environment, and can only be used in low, medium and low speed, which is the disadvantage of this kind of coupling.
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 frequent high and low speed movement. Working temperature of -20 ~ +80 ℃; transmission nominal torque of 40 ~ 20000N.m.Get more news about Elastic Pin Coupling Wholesaler,you can vist our website!

  ● Flexible pin coupling has a large structure is simple, reasonable, easy maintenance, two 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 using precision casting, cast iron HT20-40, cast steel ZG35 Ⅱ, shaft hole and keyway with drawing, the pin made of MC nylon b made.

  ● Elastic pin coupling is made of a number of non-metallic elastic material made of the pin, placed in the flange half of the coupling flange, through the pin to achieve the coupling of the two halves, the coupling structure is simple, Easy to manufacture, replace the 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. HL type - flexible pin coupling basic parameters and the main dimensions
it''s characterized by simple structure, convenient installation and easy replacement, small size, light weight.Due to the deformation of elastic sleeve squeeze is small, and the elastic sleeve and the fitting clearance of pin hole shoulds not be too big, so elastic dowel pin shaft coupling buffer and damping is not high, compensate the relative displacement between the two axis is smaller.

Widely used in the not big mpact load area , based with good rigidity, driven by a motor to the precision of various kinds of medium and small power drive line.
