JSB quick mounting serpentine shaft coupling for heavy machine

It is a kind of flexible coupling with hight allowable rotation speed adn large nominal torque,In China we title it felxible coupling.But in other countries ,also call it grid shaft coupling .A grid coupling consists of two flanged hubs connected by a serpentine flexible grid element. The grid element allows the strength of steel to drive the equipment through the full range of loading conditions to extended coupling life ,while maintaining similar misalignment and vibration damping capabilities of an elastomeric coupling.

Product Description

What is a serpentine flexible shaft coupling ?

It is consist of 3 parts :hub ,the 2 pieces outer shell ,and the serpentine spring which was made by steel.As serpentine spring is the main features ,so we call it serpentine spring shaft coupling.

The aadvantages of serpentine spring coupling :

1 Its suitable for Medium and high power transmission shaft system ;with certain compensation for the relative offset of the two shafts, vibration reduction and buffering performance,

2  the working temperature is -30 ℃ ~ + 150 ,

3 Safe and reliable operation, simple structure and convenient disassembly

High transmission efficiency, safe starting and long service life

 4 Fewer parts, small size and light weight

5.  Relies on that spring piece embedded in the gear groove of the two coupling halves to transmit torque, mainly composed of two coupling halves, two outer covers, two sealing rings and serpentine spring.

Bellow is thedrawings of rigid shaft coupling

Here is the parameters of the serpentine shaped spring coupling :

Note:1 The weight measured by the coupling without hole,L2 is the size of the outer shell when installing.
