Abstract

1340593 Lubricating; change-speed gear GKN TRANSMISSIONS Ltd 15 June 1972 [25 May 1971] 16802/71 Headings F2A and F2D A transmission system having interconnected first 42 and second 87 gearings in adajcent first 32 and second 12 casings is provided with a lubrication system. Each casing has a sump, the sump of the first casing being at a lower level than the sump of the second casing and the level of lubricant 34 in the first sump normally being lower than the level 86 in the second sump. The first gearing 42 splashes lubricant from the sump, which is collected in a collector 40 arranged above the normal levels of the two sumps, and then flows to the external surface of a hollow shaft 50 of the second gearing, which rotates during operation and which acts to pump lubricant towards the second gearing. The lubricant is pumped through apertures 53 in the shaft to the hollow interior from which it is flung during operation to lubricate the second bearing. The lubricant returns to the second sump which has means 84 for returning lubricant to the first sump while retaining lubricant at the normal level in the second sump. The external surface of the shaft may be provided with helical grooves 54 which pump the lubricant. Grooves 55 may also be arranged to pump lubricant from the second sump to the apertures of the shaft into its hollow interior, and thence to the second gearing.
