<p>A speed multiplier (increaser) of the type having an epicycloid gear train equipped with a manifold (9) housed in a corresponding annular groove (13) of the casing (2), which groove receives the coolant gathered by the manifold (9); several ducts (18) for taking up the coolant from an annular cavity (16) located above the manifold (9) and into which several ducts (14, 15) convey the coolant taken up by nozzles (7) mounted on the nose (70) of the mandrel (arbour, chuck) of the machine or equally well by the tailpiece (8) for locking the multiplier onto the mandrel; a chamber (22) for recovering the coolant supplied from outside the machine by means of a non-return valve (21). The said groove (13) feeds, through corresponding ducts (19), three nozzles (20) which are fixed on the casing (2) and orientable, and the said chamber (22) feeds another nozzle (24) fixed to a flange (3) which is secured to the casing (2). <IMAGE></p> |
