Abstract:
A non-reverse ratchet assembly includes a stationary ring with a plurality of saw teeth equally distributed over an outer surface of the stationary ring; a rotating housing with a rotating ring surrounding the stationary ring; and a plurality of ratchet elements equally distributed and positioned between the rotating ring and the stationary ring, wherein each ratchet element is configured to engage with or disengage from the plurality of saw teeth, and wherein each ratchet element comprises a slot for a distributed load sharing of the plurality of ratchet elements when engaging with the plurality of saw teeth. Furthermore, a vertical shaft motor including a non-reverse ratchet assembly is described.
