How the Screw Attaches to the Motor
Fixing the motor to the lead screw usually requires (A) a coupling assembly, (B) a counter-bore press fit or (C)
a hollow shaft press fit. The assembly process may entail the use of
adhesives or welding. All these solutions make it difficult or
impossible to change lead screws or perform maintenance. Thomson has
solved this issue with (D) our patented Taper-Lock coupling that requires only a single retention fastener.
