Abstract
A cage with bearing balls' confined therein is interposed between a plate and a planar platform, to accommodate rotation of the plate, and an electrically-powered device, such as a searchlight, can be fastened to the plate for rotation therewith. A disk, with a plurality of radially-extending fingers, is secured to the platform and is in biasingly restraint of the plate to (a) inhibit an unwarrantedly free rotation of the plate, i.e, to impose a controlled drag on the plate rotation, and (b) to enable the inverted operation of the overall combination.
Claims12
A horizontal bearing arrangement, for (a) coupling thereto, and (b) rotatably supporting, an electrically-powered device, comprising:
- a generally annular base;
- said base having a substantially planar platform and annular groove formed thereon;
- a plate surmounting said platform, having an annular trough formed therein;
- said groove and trough are in mutually confronting alignment;
- a plurality of rolling elements, interposed between and rollingly engaged within said trough of said platform and said groove of said plate, for accommodating rotation of said plate relative to said platform;
- and
- restraining means coupled to said base, and surmounting said plate, for restraining rotation of said plate, and said restraining means comprising a disk with radially-extending limbs for biasingly engaging said plate and for imposing a controlled drag on the plate rotation.
