Abstract
A stator of a locking differential includes an inner lip recessed into the central opening. The inner lip engages with a bearing race to secure the stator to a gear housing of the locking differential. The stator holds an electromagnetic coil. The stator is shaped to avoid electromagnetic flux pinch points that could limit the amount of electromagnetic force applied to a locking arrangement of the locking differential.
Claims20
A rotary device comprising:
- a rotatable housing;
- a stator including an annular housing disposed around a portion of the rotatable housing, the stator defining a central opening through which a portion of the rotatable housing extends when the stator is coupled to the rotatable housing, the stator including an inner lip extending radially into the central opening from a radially inwardly facing periphery of the stator;
- and
- a bearing race mounted around the portion of the rotatable housing at a fixed position, the bearing race being sized to fit within the central opening of the stator so that an outer periphery of the bearing race opposes the radially inwardly facing periphery of the stator, wherein the inner lip of the stator extends radially inwardly past the outer periphery of the bearing race.

- a stator including an annular housing disposed around a portion of the rotatable housing, the stator defining a central opening through which a portion of the rotatable housing extends when the stator is coupled to the rotatable housing;
- and
- a bearing race mounted around the portion of the rotatable housing at a fixed position, the bearing race being sized to fit within the central opening of the stator so that an outer periphery of the bearing race opposes a radially inwardly facing periphery of the stator, wherein a thickness of the stator does not decrease as the stator extends radially inwardly towards the outer periphery of the bearing race.

A rotary device comprising:
- a rotatable housing;
- a stator including an annular housing disposed around a portion of the rotatable housing, the stator defining a central opening through which a portion of the rotatable housing extends when the stator is coupled to the rotatable housing, the central opening extending between opposite first and second sides of the stator the stator, the stator including a portion extending radially into the central opening at the second side to define an inner lip;
- a bearing race mounted around the portion of the rotatable housing at a fixed position, the bearing race being sized to fit within the central opening of the stator so that an abutment surface of the bearing race opposes the inner lip of the stator to hold the stator to the rotatable housing.
