Built in Override Mechanism for Drive Assembly

This override mechanism is particularly suited for single or double shafted drives connected to mechanisms which require an override to protect the mechanisms in the event of a malfunction.

This override mechanism includes a motor 10 with a drive shaft 12 having mounted thereon a worm 14. The worm 14 is in turn operably connected to a worm gear 16 mounted on a load shaft 18 suitably supported in bearings 20 and having opposite ends available for driving suitable loads. Override mechanism 22 forms a driving connection between worm gear 16 and load shaft 18. The override mechanism contains a set of ball plungers 24 and detents 26. The plungers 24 can be adjusted to provide the proper torque requirements.

The override mechanism is contained within the motor gear box, thereby allowing a compact design for applications with space constraints, The design is especially suited for double-shafted motors since the override is common to both shafts and thereby provides uniform override for both load shafts.
