Abstract

A bearing housing for high speed rotating shafts wherein the bearing housing is constructed in two parts with the bearing being of the semi-floating type. One part of the bearing housing presses against the bearing to resist any axial thrust that may be exerted on the bearing during high speed operation. The bearing is floating on a lubricant around its outer diameter in the other portion of the two part bearing housing. With the bearing being stationary in the housing, the only critical surface becomes the internal surface between the bearing and the shaft itself. By varying the position of the two parts of the bearing housing, the passage for the lubricant to enter the bearing housing can be located at a near vertical position while permitting desired orientation of the end of the bearing housing.

Claims5

Dependent claims

A high speed bearing housing means comprising two parts for receiving a shaft and bearing means that circumscribes a portion of said shaft with the shaft connecting at least two rotatable thrust load producing members in a spaced-apart relation:

a first part of said two parts of said bearing housing means being adapted to receive said shaft and bearing means, said first part having means to receive and means to remove a fluid from said first part and a first sealing means for sealing said first part around said shaft, said fluid lubricating said shaft and bearing means to allow easy rotation of the shaft therein;
a second part of said two parts of said bearing housing means being adapted to receive said shaft, said second part being secured to said first part and bearing any axial thrust that may be exerted on said bearing means;
said second part having a second sealing means for sealing said second part around said shaft;
and
third sealing means for preventing fluid loss between said two parts of the housing;
the location of said receiving means and removing means in said first part being determined by the relative position of said first and second parts, said second part being positioned to accomodate the device on which said bearing housing means is being used, said first part being rotatably positioned to allow fluid flow by gravity.
