A thrust bearing comprises a pair of bearing members and an intermediate seat member. The two bearing members are mountable to a rotating shaft and each includes a substantially spherical bearing surface. The seat member is held between the bearing members, but is free of said rotating shaft. This seat member has oppositely facing, substantially spherical bearing surfaces for mating with and bearing against the substantially spherical bearing surfaces of the two bearing members.

A thrust generator including a superconducting solenoid magnet 1, a thrust duct 2 and a power supply device 3. The spiral portion of the thrust duct 2 is inserted in the hollow interior of the superconducting solenoid magnet 1. Anode 8 and cathode 9 are fixed at both inner walls of the thrust duct 2. Electric power is supplied to an electromagnetic fluid 10 in the duct 2 to produce a magnetic field and a Lorentz's force f. The electromagnetic fluid 10 flows into the thrust duct 2 through an open...

A ship has an electromagnetic thrust generator including a cylindrical magnet in which there is arranged a helical duct for conducting sea water. The magnet includes a coil housing in which a superconducting coil is disposed. The duct includes an outer wall disposed opposite the internal surface of the coil housing. Electrode members are mounted on inner and outer walls of the duct to create an electrical field across the duct.

A half-ring thrust bearing for the axial location of shafts in housings, particularly, for the axial location of crankshafts in cylinder blocks. The thrust bearing is seated in a fully circular or annular seat and is prevented from rotating relative to the seat by a tag or tang extending axially or radially from one end of the half-ring.

The new thrust washer includes an inner flange with circumferentially spaced cutouts. The washer is formed from flat strip steel. A circular hole and a plurality of cutouts extending from the circumference of the circular hole are made in the flat strip steel. The circular hole and cutouts may be made consecutively or simultaneously. A forming tool forms the inner flange.

This is an apparatus for use in a thrust bearing. A plurality of rolling member carriers are arranged to move along the thrust race. A pocket is formed in each carrier and contains a rolling member such as a roller. Means are provided for preventing rotation of each carrier about its own center in its movement along the race.

A permanent magnet thrust bearing in which there is provided a pair of members mounted respectively on a shaft and a fixed body, with one of said members being formed from high permeability material and the other member being a permanent magnet, with said members being continuously presented to each other so in use the shaft rotates relative to the fixed body so that the magnetic flux of said permanent magnet serves to locate said shaft axially with respect to the body.

The thrust race comprises circumferentially spaced tabs on the outer flange with cutouts located circumferentially adjacent each side of each tab. The thrust race is formed from sheet metal. Annular blanks are blanked in the sheet metal, the cutouts are made on the outside perimeter of the annular blank, the tab between each pair of cutouts is formed, and the annular blank then removed from the flat sheet metal. The outer portion of the annular blank is bent to form an axially extending outer fl...

A thrust device of the kind in which an axial thrust is produced by relative angular movement between two substantially parallel thrust plates between which balls or rollers co-operate with inclined ramp surfaces, for use in a spreading type disc brake for example. Deformable means are provided between a ramp member and a thrust plate carrying it to allow the ramp member to be displaced axially on initial actuation of the device to even out the load between the balls or rollers for subsequent ac...

This invention is a new thrust bearing cage and a new method for assembling a thrust bearing cage on an annular thrust race. The thrust bearing cage includes a plurality of adjacent carriers each having a tab extending from one side and a circumferentially opposed recess. The carriers are permanently connected together by suitable means such as by welding the tab in the recess of an adjacent carrier. The new cage can be assembled within a thrust race by arranging the carriers in side-by-side rel...
