The Lovejoy Oldham coupling is a precision engineered, torsionally stiff, three-piece coupling suitable for a great many
applications ranging from incremental control of fluid valves to highly dynamic drives in closed loop servo systems. It
accommodates misalignment mechanically through a floating disc that engages tenons machined out of the hubs. As the coupling rotates, the floating disc aligns with each hub alternately to an extent demanded by the alignment error.
Because parallel misalignment is accommodated by lateral displacement, the Lovejoy Oldham coupling can handle severe
alignment errors within a short space envelope. This is a valuable feature in densely packaged and blind assemblies, or
where misalignment can accelerate the erosion of shaft bearings.
The Lovejoy Oldham coupling features raised dots on both sides of the floating disc which act as an effective spacer. The
dots keep the face of the tenon from contacting the bottom of the floating disc and allows the coupling greater angular
misalignment capability. A very important effect is that the spacer dots will greatly reduce the bending load on the shafts
because of the freedom of the floating disc.
The MOL Coupling consists of two hubs and one center member.
