Abstract
In an assembly with two concentric shafts, the internal shaft projecting beyond the external shaft, a seal support sleeve placed between the shafts has a conical shape and bears on a spacer mounted on the external shaft between an assembly nut of the forward end of the external shaft and a bearing, so that the nut is accessible to be unscrewed through the space between the two shafts, thus enabling the external shaft to be disassembled. The invention may be applicable to front bearings of gas turbine high pressure shafts and makes it possible to disassemble the high pressure body from the rear, without needing to disassemble equipment, such as a fan on the front of the machine, or hindering the installation of a gear.
