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

Table of contentsteeth of the spider are crowned to avoid edge pressure if the shafts are misaligned. RYDON jaw couplings are capable of compensating for axial, radial and angular
