Bearing Assembly With a Powder Lubrication System,

Abstract

The powder lubricated bearing consists of a bearing with shaft in ribbed casing. The lubricating power is distributed by means of a centrifugal impeller with diffuser on one side of the bearing connected by means of a pipe to a ribbed swirl chamber with quick-release cover on the other side. A small amount of lubricating powder is placed in the swirl chamber, and when the shaft is rotated the powder is sucked through the bearing through three throttling holes by the impeller and returned by the connecting pipe to the swirl chamber. The suction of the powder through the bearing together with air at high speed provides constant lubrication of bearing surfaces, equal temps. and efficient heat dispersal. (Author)
