Application of Zero Backlash Elastomer Insert Elastic Jaw Flexible Shaft Coupling

CNC machine, CNC lathes, CNC machine center,

CNC milling machine ,engraving machine, metallurgical machinery, mining machinery,

petroleum machinery, Chemical Machinery, Hoisting Machinery,

Transport Machinery, water pump, Fan, etc


Advantage of Zero Backlash Elastomer Insert Elastic Jaw

Flexible Shaft Coupling

1.Elastomer connecting in the middle

2.Can absorb vibration, compensates for radial, axial and angular deviation

3.Oil resistance and electrical insulation

4.Have the same characteristic of clockwise and anticlockwise rotation


In addition to jaw couplings being considered fail-safe and all the other advantages already discussed above (damping capacity, chemical resistance, etc.), jaw couplings are considered maintenance-free as they do not require lubrication. Unlike gear, grid, or chain couplings that require periodic re-greasing… as long as the spider remains intact, the dog coupling will continue to operate without additional maintenance.

The traditional form of jaw coupling transmits torque through a compressed elastically flexible element (meaning the star leg is crushed). From an elastic element standpoint, this is preferable for torque transmission, as elastomers can generally take more punishment and load (including handling peak loads) when compressed (squeezed) than alternatives.. …this is shearing (being pulled or stretched).

Given that the claw coupling is widely accepted as the basis of industrial couplings, the ultimate benefit of this design is that there are now a large number of specialized claw coupling variants for almost every industry you can imagine. . Provide great design flexibility for equipment designers, maintenance engineers, etc.

Agknx Engineering offers a variety of jaw couplings that act as flexible couplings with an additional failsafe feature. Jaw couplings can be comprised of an elastomer or spider sandwiched between two hubs. These couplings are easy to install and provide a failsafe feature in their continued capacity to transfer torque in the event elastomer failure.
