A sealed transmission assembly coupling a first rotary shaft mounted in a first casing to a second rotary shaft substantially aligned with the first shaft and mounted in a second casing fixed to the first casing is disclosed which enables replacement of leaky seals or part of the transmission chain to be effected quickly and without disconnecting the second casing from the first casing. In this assembly the first shaft is tubular, the second casing has a tubular protrusion which extends through the first casing inside the first shaft and projects into a chamber defined by a cover which is removably secured to the first casing on the opposite side from the second casing, the second shaft has an extension projecting through the tubular protrusion, a removable driving member connects the end of the extension to the first shaft for rotation therewith, and removable sealing means are disposed between the driving member and the end of the tubular protrusion projecting into the chamber, the arrangement being such that the driving member and the sealing means can be disassembled, after removal of the cover, without disconnecting the second casing. |
