| (3) E.9/HP.24.8.32. the blower and the crankshaft, and crankshaft movement, due to temperature difference effects is catered for by a certain amount of end float in the coupling, or by sliding on the splined shaft under load. The end float in the coupling should also provide for any misalignment present in the drive apart from eccentricity. Lubrication of the slipper flywheel bearings is catered for by a drilling up to the cross drive chamber which dribbles some oil under a slight head on to the rear portion of the crankshaft flange, whence it is caught up and distributed to the bearing surfaces and friction discs. The coupling itself, we think, will get enough oil from splash and vapour. The rear end cover on the blower has the annular chamber previously discussed connected to the air inlet of the carburetter, but we are hoping to simplify this cover by avoiding the double spigot construction. Further work is being added to LeC.3167 dealing with the remaining particulars of the front end, and the centre portion of the blower, and this will be sent through later. A print of LeC.3167 is also attached to Da{Bernard Day - Chassis Design}'s copy for reference in respect to the chassis. E.{Mr Elliott - Chief Engineer} | ||
