Definitions

  • Tr.is invention relates tc compressor assemblies anc relates more particularly to an air compressor assembly incorporating a clutch on the drive shaft thereof.
  • a ⁇ compressor assembly including a housing have a rotatable input shaft for connection to a prime mover said shaft running in a first outer bearing in the housing and incorporating an input part of a multi plate clutch characterised in that said input part is embraced by a clutch output part drivably located on a compressor shaft and said input part having an axial recess accommodating retaining means for the clutch output part on the compressor shaft and also inwardly thereof on the compressor a bearing shaft/about which the inner end of the input part is rotatable on the compressor shaft in a disengaged condition of said clutch.
  • the compressor has a cast metal housing in the form of a combined crankcase and cylinder cenotec by reference 1, the cylinder being providea with a valve plate 2 containing the necessary valves cooperating with a cylinder head 3 with suitable inlet and output ports, the details of which are of no consequence in relation to the present invention and may be of a suitable construction.
  • the compressor is provided with a piston 4 and a connecting rod 5 for effecting recipro- ation of the piston 4 in the bore 6 of the cylinder by virtue of rotation of a crankshaft 7 the free end of which runs in a bush 8 in an end plate 9 on one end of the crankcase.
  • crankcase The other end of the crankcase is provided with a generally cylindrical integrally cast extension 10 which houses a clutch assembly via which the crankshaft is driven by a rotatable input shaft portion 11 which runs in a ball bearing 12 captive in a further end plate 13 on this end of the housing.
  • the outer end of the shaft 11 is provided with a key-way 14 and suitable fixing means for mounting a gear wheel for engagement with a gear train of an internal combustion engine for driving the compressor.
  • the input shaft 11 is integral with an input part 15 of a multi-plate clutch this input part being coaxial with and embraced by an output part 16 of the clutch the output part being carried on a spline 17 on the crankshaft of the compressor.
  • the input part 15 has splines 32 engageable with inward projections 30 of inner plates 31.
  • the output part of the clutch comprises a cage 19 of a hub portion with axial slots in which outward projection of outer clutch plates 29 are to locate.
  • Outer part 18 is directly splined to the crankshaft at 17.
  • Co-operable with the outer plates 29 of the clutch the cage 19 is urged into a clutch engaged position by a pair of annular disc springs 20.
  • the clutch assembly is retained together by an internal circlip 21 located in the cage 19 for reacting the force of the disc springs 20 and pneumatically operable clutch release means in the form of an annular piston 22 is provided engageable with the cage 19 through a thrust member 23 in a sense to compress the springs 20 and release the clutch.
  • Piston 22 is keyed against rotation by a locating pin 28.
  • the main bearing of the compressor on the drive side is provided by a substantial ball race 24 and the inward end of the input shaft and clutch input member 15 is carried on a bearing 25 withinicoaxial recess 33 of the input part 15.
  • Fixing means for retaining the bearing on the crankshaft comprises a threaded end portion of the crankshaft carrying a suitable retaining nut to clamp bearing 24, hub portion 18 and bearing 18 in position on the crankshaft.
  • the compressor which includes the crankshaft, connecting rod and piston is first assembled together with the necessary valve plate and cylinder head components.
  • the output member 16 of the clutch assembly is assembled as a separate unit with plates properly aligned following which the pneumatic release piston 22 is placed in position, the clutch assembly comprising the inner and outer plates and the disc spring 20 (retained together by virtue of the circlip 21) is placed onto the spline 17 on the crankshaft 7 followed by the bearing 25 and the fixing means including the retaining nut 26.
  • the clutch assembly In operation of the assembly, in the absence of a suitable compressed air signal in the control passage 27 from a governor or control valve, the clutch assembly will be in the engaged condition and therefore full drive torque will be applied on the input shaft 11 through the clutch assembly to the crankshaft of the compressor which is therefore in a charging mode for charging compressed air storage reservoirs.
  • the governor or control valve Upon attainment of a first predetermined compressed air pressure in the reservoirs, the governor or control valve will provide a pressure signal via the passage 27 to the release piston 22 which will thereby be urged leftwards to compress the disc springs 20 and quickly release the clutch.
  • the compressor stops until at a second lower pressure the controlling pressure signal in passage 27 is again removed to re- engage the clutch.
  • any tendency for rotation of the piston 22 is prevented by a locating peg 28 which holds the piston 22 in a given position in relation to the housing.
