Jaw & Spider Couplings
A BRIEF OVERVIEW BY JOSEPH BARLOW
Lovejoy developed the Jaw-style coupling in 1927
Jaw & Spider couplings are popular because they are versatile and robust.
Jaw & Spider Couplings are FailsafeWide Temperature Range
Can handle Angular MisalignmentGood Torque, Speed, Chemical Resistance, & Dampening characteristics
Versatility&
Robustness
Dampening reduces effect of shock and vibration. Angular Misalignment (slight)
Able to endure tough Environments
Jaw & Spider Couplingsare forgiving
butAlignment is still Critical
Torsional Misalignment
Overload Disadvantages
Sheared Spider
Overloaded Hub
Hub overload
Bottom LineLow Cost
AvailabilityServicability
Jaw & Elastomeric Spider
