Abstract:
Apparatus for adding a torsion dampened power take-off gear to the distal end of a driven shaft of an internal combustion engine, said apparatus comprising:a. a coupling sleeve dimensioned for sliding coaxial receipt of said driven shaft's distal end, said coupling sleeve having proximal and distal ends;b. means for preventing said coupling sleeve from rotating with respect to said shaft;c. a longitudinal channel in said coupling sleeve's outer surface at said coupling sleeve's distal end;d. a gear slidingly and coaxially disposed upon said coupling sleeve's distal end;e. a channel in said gear's interior annular surface, said gear's channel being aligned with said coupling sleeve's channel thereby defining a key way, said gear's channel being substantially wider than said coupling sleeve's channel;f. a key in said key way, said key being dimensioned so as to be snugly received in said coupling sleeve's channel, but very loosely received in said gear's channel;g. a dense, resilient material in said gear's channel, said dense, resilient material filling all space in said gear's channel not occupied by said key;h. means for locking said gear and coupling sleeve to said driven shaft's distal end.
