Abstract
Abstract A coupling assembly for two aligned rotating shafts connected together by shear bolts. The coupling assembly includes a casing which limits the axial movement of the shafts by engaging a surface of one of the shafts after shearing occurs and the connection between the shafts has been severed. The casing is connected to the shaft in a manner that forms a chamber for housing a lubricating fluid to ensure lubrication of the relatively moving parts of the coupling assembly after shearing occurs. A circumferential taper is provided on one of the shafts to cause the lubricating fluid to generate hydrodynamic pressure after shearing occurs.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
157 words
A coupling assembly for aligned first and second shafts comprising: a. flanged portions on each of said shafts, said flanged portions having openings therein; b. a plurality of shear bolts receivable in said openings for joining the flanged portions of the shafts together; c. a casing having an axially extending portion abutting the flanged portion of said first shaft and a radially extending portion surrounding said second shaft; d. a plurality of assembly bolts engaging said axially extending portion of said casing for assembling said casing to the flanged portion of said first shaft; and e. means for retaining lubricating fluid within said coupling assembly, said means comprising a chamber formed between said casing and the flanged portion of said first shaft, a gasket disposed between said axially extending portion of said casing and the flanged portion of said first shaft, and a seal disposed between said radially extending portion of said casing and said second shaft.
Claim 2
Dependent Claim
157 words
A coupling assembly for aligned first and second shafts comprising: a. flanged portions on each of said shafts, said flanged portions having openings therein; b. a plurality of shear bolts receivable in said openings for joining the flanged portions of the shafts together; c. a casing having an axially extending portion abutting the flanged portion of said first shaft and a radially extending portion surrounding said second shaft; d. a plurality of assembly bolts engaging said axially extending portion of said casing for assembling said casing to the flanged portion of said first shaft; and e. means for retaining lubricating fluid within said coupling assembly, said means comprising a chamber formed between said casing and the flanged portion of said first shaft, a gasket disposed between said axially extending portion of said casing and the flanged portion of said first shaft, and a seal disposed between said radially extending portion of said casing and said second shaft.
Claim 3
Dependent Claim
30 words
A coupling assembly defined in claim 1, wherein said flanged portion of said second shaft includes a circumferential taper for generating hydrodynamic pressure in said lubricating fluid after shearing occurs.
