<p>A plug 1 plugs into a ROV drive bucket limiting rotation of a drive shaft therein to say 15° and reducing the build up of marine growth in the bucket. As shown it includes a polyethylene body (which may be made in two parts 12, 13) housing a metal socket 11 mounted for limited angular orientation therein. The socket has a twenty four point aperture or recess 22 which fits over a squared end of a drive shaft 10 at various angles orientation. The socket has external splines 20 which fit loosely in wide internal grooves 21 in the body and self orientates within the body when the body is plugged into the bucket. The plug has a pair of diametrically opposite dogs 4 which engage in slots 5, included in flanges on conventional buckets.</p> |
