Means Of Mounting A Revolving Cutting Element
Means Of Mounting A Revolving Cutting Element
US Patent:
5352045, Oct 4, 1994
Filed:
Jan 6, 1993
Appl. No.:
8/001317
Inventors:
Ronald Bennett - Nyon, CH
Lewis J. Isaacs - Littleton CO
Kenneth Jump - Arvada CO
Lewis J. Isaacs - Littleton CO

Assignee:
The Integrated Bearing Co. Ltd. - Tortola
International Classification:
E21B 1022
US Classification:
384 96
Abstract:
In an assembly made up of a spindle formed integrally with a revolving cutting element, the longitudinal axis of the spindle being the axis of rotation of the cutting element, the spindle is set into a cylindrical bearing. The bearing is fixed in the main body of the bit. The bearing element and a plate form a thrust surface with the end of the bearing at right angles to the axis of rotation of the spindle, which the other end of the bearing element made with the flange projecting outwards is held in the cutting element by means of the retaining ring which is fixed in the cutting element. A thrust surface at right angles to the axis of the rotation of the spindle is created between the top end of the bearing element and the cutting element and another between the retaining ring and the main body of the bit. By maintaining the spindle centrally in the bearing the wear on the bearing is radically reduced.

Assignee:
Jemco Seal Corporation - Broomfield CO
International Classification:
F16J 1532
US Classification:
277353
Abstract:
A seal assembly is adapted for mounting between a rotatable shaft and an outer stationary housing, the seal assembly being made up of a metal sleeve in surrounding relation to the shaft, a non-metallic resilient seat in surrounding relation to the sleeve, the seat being heat-expandable to permit placement over the sleeve and, upon cooling, will contract or shrink into snug-fitting engagement with the sleeve along selected areas with labyrinth grooves formed along the inner surface of the seat between the selected areas of sealed engagement; and an excluder ring is mounted on one end of the seat along with an annular drive lock which is wedged into one end of the sleeve so as to impart rotation of the shaft into the sleeve and excluder ring.
