Abstract
1,102,937. Bearings; lubricating. WESTLAND AIRCRAFT Ltd. 17 Aug., 1966 [18 Aug., 1965], No. 35517/66. Heading F2A. [Also in Division F1] Ball or roller bearings of a turbo-unit are lubricated by means of an oil-mist circulated therethrough by a rotary air-pump, the oil-mist being produced by passage of air over oil deposited on the shaft of the unit. The oilentraining air is returned to the air-pump after having passed through the bearings. In an embodiment, a shaft 4 has two rotary air-pumps 11 mounted thereon, is supplied with lubricant by means of two wicks 10 which lead to an oilsump 9, and is supported by ball-bearings 5 mounted in a carrier 6. The latter is provided with radial fins and is received in a sleeve 7, the radial fins dividing the cylindrical space between the carrier 6 and the sleeve 7 into an even number of longitudinal passages divided into two interdigitated groups allocated respectively to the circulation of air carrying lubricating mist and to cooling air. The oil-mist is passed through longitudinal passages 13, through the bearings 5 and is returned to the passages 13 via circular grooves 16 in endplates 14, 15 and ports 17. Cooling-air is forced through ports 23 into longitudinal passages 24 by a fan 22 mounted on the shaft 4 and enters through ports 25 into an annular space formed between the end-plate 15 and a restrictor-plate 26. The cooling air then escapes through an annular gap 27 formed by the plate 26 and a collar 21 of the shaft 4, and, in escaping causes a back-pressure which is sufficient to prevent leakage of oil through a labyrinth seal 19 provided between the collar 21 and the end-plate 15. In modifications, the wicks 10 may be replaced by small-bore pipes, the circulating air being passed over the ends thereof and a breather arrangement may be provided.
