The Lovejoy Mini Soft coupling provides protection from misalignment, vibration and shock
loads. The simple design of the coupling ensures ease of assembly, installation and reliable
performance. No special tools are needed for installation or removal. No lubrication is needed,
and once installed and aligned correctly, no maintenance is required.
The Mini Soft coupling design is comprised of three parts. Two hubs with internal teeth engage
an elastomeric flexible center, or sleeve, with external teeth. Misalignment and torsional shock
loads are absorbed by shear deflection in the center sleeve element.
The shear characteristic of the coupling is very well suited to absorb impact. The Lovejoy Mini
Soft coupling is designed with tooth contact which provides more surfaces carrying the load
resulting in less wear at any one point, and torque that flows more smoothly. Additionally, the
coupling allows for axial freedom which results in easier assembly and spacing of shafts. This
feature is particularly useful in reducing thrust loads on bearings.
When operating within its rating, the coupling is torsionally stiff and will not react with twist during
operation. The Polyurethane center member sleeve is known for its toughness and resistance to
abrasion, and also provides for good damping and shock load capabilities.
The MSF coupling consists of two hubs and one center member.
