Abstract
A bearing assembly and method of construction that provides a bearing having a plurality of individual flat bearing disc inserts, such as carbide inserts, supported directly upon a flat insert support surface. The method of construction utilizes a mold for simultaneously brazing the inserts to the bearing surface.
Claims18
A bearing assembly comprising:
- (a) a support member, said support member having a plurality of bearing insert retainer slots, each said slot having a fiat bearing surface;
- (b) a plurality of flat bearing disc inserts positioned within each said bearing insert retainer slot against said flat bearing surface;
- and
- (c) brazing material positioned around each of said flat bearing disc inserts in each said bearing insert retainer slot whereby when heat is applied to said brazing material said bearing disc inserts will simultaneously be brazed and held in place within said bearing insert retainer slots.

A radial bearing assembly comprising:
- (a) a tubular support member, said support member having a plurality of longitudinally extending, radially spaced, bearing insert retainer slots, each said bearing insert retainer slot having a flat bearing surface;
- (b) a plurality of flat bearing disc inserts positioned within each said bearing insert retainer slot;
- and
- (c) brazing material positioned around each said bearing disc insert in each said bearing insert retainer slot whereby when heat is applied to said brazing material, each said bearing disc insert positioned within each said bearing insert retainer slot will be simultaneously brazed and held in place within said bearing insert retainer slot against said flat bearing surface of said retainer slot.

A radial bearing assembly comprising:
- (a) a tubular support member, said support member having a plurality of longitudinally extending, radially spaced, bearing insert retainer slots, each said slot having a flat bearing surface;
- (b) (c) a plurality of flat bearing disc inserts positioned between said tubular support member within each said bearing insert retainer slot against said flat bearing surface of said bearing insert retainer slot;
- and
- (c) brazing material fed into a space created between said tubular support member and a removable tubular brazing mold, whereby when heat is applied to said brazing material, each said disc insert, positioned within each said bearing insert retainer slot will be simultaneously brazed and held in place within said bearing insert retainer slot against said flat bearing surface of said retainer slot.

A radial bearing assembly comprising:
- (a) a tubular support member, said support member having a plurality of longitudinally extending, radially spaced and longitudinally staggered bearing insert retainer slots each said slot having a flat bearing surface;
- (b) a plurality of flat bearing disc inserts positioned between said tubular support member within each said bearing insert retainer slot against said flat bearing surface of said bearing insert retainer slot;
- and
- (c) brazing material fed into a space created between said tubular support member, whereby when heat is applied to said brazing material, each said disc insert positioned within each said bearing insert retainer slot will be simultaneously brazed and held in place within said bearing insert retainer slot against said flat bearing surface of said retainer slot.
