Motor Shaft Security Apparatus

US Patent:
8025110, Sep 27, 2011
Filed:
Jan 26, 2009
Appl. No.:
12/321827
Inventors:
Chad M. Daigle - Lafayette LA, US
International Classification:
E21B 4/00, E21B 19/18
US Classification:
175101, 175106
Abstract:
A down hole drilling motor shaft security apparatus is disclosed. The apparatus has a general body housing threadedly attached to a lower radial bearing housing and an output shaft extending from the lower radial bearing housing. Within the general body housing is a thrust bearing assembly that secures a portion of the output shaft within the general body housing and the lower radial bearing housing. An intermediate sleeve having a capture groove of an elongated predetermined width is threadedly attached to the output shaft. An interference structure that is secured to the general housing extends radially into the capture groove in a manner that prevents axial loads from being transmitted to the intermediate sleeve from the interference structure while the bearing assembly is intact. The interference structure is configured to secure the intermediate sleeve and the output shaft to the general housing by engagement with the capture groove of the intermediate sleeve in the event of axial movement of the intermediate sleeve a preselected amount.

Motor Shaft Security Apparatus

US Patent:
7445061, Nov 4, 2008
Filed:
Mar 14, 2005
Appl. No.:
11/080095
Inventors:
Chad M. Daigle - Lafayette LA, US
International Classification:
E21B 4/00
US Classification:
175106
Abstract:
A bearing assembly is situated to conduct axial forces between the general housing and the output shaft by way of an intermediate sleeve that is secured to the output shaft outside the general housing and is axially confined by a bearing assembly secured to the general housing.

Adjustable Deflecting Sub

US Patent:
6799646, Oct 5, 2004
Filed:
Sep 3, 2002
Appl. No.:
10/234582
Inventors:
Chad M. Daigle - Lafayette LA
Toby S. Baudoin - Lafayette LA
Assignee:
Tomahawk Downhole, LLC - Lafayette LA
International Classification:
E21B 708
US Classification:
175 74, 175256
Abstract:
As a serial element of a drill string, the drill string is adjustably bent by rotating one end of the sub relative to the other end. The opposite ends rotate about a tilted center line such that in one rotational position the sub is straight. One half turn of one end relative to the other bends the sub to the maximum angle. Between straight and maximum bend, any angle can be achieved by control of the amount of the relative rotation between the opposite ends of the sub.

Sealed Flexible Motor Coupling

US Patent:
6997811, Feb 14, 2006
Filed:
Mar 26, 2004
Appl. No.:
10/811037
Inventors:
Chad M. Daigle - Lafayette LA, US
International Classification:
F16D 3/84
US Classification:
464 19, 464173, 175101, 1753255, 27634, 27637
Abstract:
A hermetic seal functions as a closure between opposite ends of the coupling by combining a metal sleeve and an elastomer sleeve extension. The metal sleeve is sealingly attached to the outer surface of one end of the coupling and the elastomer sleeve, sealingly attached to the metal sleeve, is attached at the distal end to the other end of the coupling. As an alternative, the distal end may be bonded to a second metal sleeve sealingly attached to the other end of the coupling. The seal may be convoluted, with multiple convolutions.

Drilling Motor Coupling

US Patent:
2010019, Jul 29, 2010
Filed:
Jan 26, 2009
Appl. No.:
12/321817
Inventors:
Chad M. Daigle - Lafayette LA, US
Assignee:
TOMAHAWK DOWNHOLE LLC - Lafayette LA
International Classification:
F16D 3/16
US Classification:
464157
Abstract:
A flexible drilling motor drive shaft coupling has two torque transmitting portions spaced apart axially, preferably, by a compression unit that is secured to one portion by a tension link and entrapped within the other portion. The tension link is, preferably, a cap screw extending along the axis of rotation of the coupling.
