Title: Shaft connection
Inventor: PETRIE JAMES ALEXANDER
IPC: F01D5/02
Filed: 1971-06-30
Abstract: 1282400 Breaking pieces ROLLS-ROYCE (1971) Ltd 30 June 1971 30613/71 Heading F2X  A shaft connection adapted to disengage when overloaded in a predetermined sense comprises two shaft portions 22, 24 and a splined sleeve 28, the latter having a helically splined connection 27 with portion 24 and an axially splined connection 29 with portion 22, and being rigidly held against movement in one axial direction by a flange 30 adjacent the splines 29 on shaft portion 22 and held against movement in the opposite direction by a deformable stop 31 (or, alternatively, a frangible stop) so that on deformation or breaking of the stop sleeve 28 moves to disengage the axial splines 29. The deformable stop 31 comprises a U-section ring which deforms when overload occurs so that the limbs of the 'U' are forced together. The shaft portion 22 may carry the annulus gear (21) of an epicyclic gear (Figure 2, not shown) linking a shaft (17) driven by the turbine of a gas turbine engine with a shaft (18) driving the front fan of the engine. A sun wheel (16) on shaft (17) drives a plurality of planet or pinion gears (20) carried by a carrier (19) on the shaft (18) and reacting on the stationary internal annulus gear (21). The shaft portion 24 is bolted as at 25 to a stationary structure 23 of the engine. Under normal operation, the reaction of the annulus gear (21) causes a torque on the sleeve 28 which tends to move it by the action of the helical splines 27 to force it against the flange 30. In this way the shaft portion 22 is maintained stationary. Should one of the gears (20) seize on its bearing, the loads on the annulus whell (21) and shaft portion 22 are immediately reversed, causing the sleeve 28 to push against the deformable ring 31; due to the magnitude of the loads involved the ring is crushed. The axial movement of the sleeve 28 is sufficient to disengage the axial splines 29 and consequently the shaft portion 22 is freed in rotation. Hence the gear will form a rigid drive connection and will provide a direct drive from the turbine to the fan which will result in slowing down of the turbine.
