Abstract

The spindle has a cylindrical body (1) which comprises at its upper end a projection which forms an annuals. The shaft (2) goes through the spindle (1), and one end (2') of the shaft is conical to take the drive pulley (5), which is keyed to the shaft by a pin (7) and has an end nut (6). Fluid is introduced into the spindle through the openings (15) and the passages (17) and (18). The passages are plugged by the plugs (22) in service. The fluid under pressure passes through the micropores of the material to the spaces (21).
