ABSTRACT:
Open-end spinning machine apparatus is provided which includes a spinning shaft with a spinning rotor at one end and a driving whorl at the other. A bearing assembly is provided including two sets of roller bearings spaced axially from one another and in bearing engagement with the spinning shaft. In order to accommodate replenishment of lubricant to the roller bearings during operation, an oil-feed device is provided which is responsive to the speed of the spinning shaft to supply oil thereto. In preferred embodiments, the oil-feed device includes an oil reservoir adjacent a sealing element which faces the spinning shaft, which sealing element is responsive to reduced pressure caused by rotation of the spinning shaft to supply oil thereto, with no oil being supplied with a stopped spinning shaft.
