Patent number: 7338379Abstract: An inner tubular wall is concentrically located inside an outer tubular wall to form an annular space therebetween. A bearing is retained within the annular space. The bearing can include a pair of precision angular contact bearings, the bearing may also include an axial sleeve bearing. A frangible element such as an annular shear groove is associated with one of the outer tubular wall and the inner tubular wall. Separation occurs at the frangible element and the bearing supports the inner tubular wall member and the outer tubular wall member for rotation relative to each other upon the coupling assembly experiencing a shear event. In addition, the angular contact bearings may reduce any bending moments that might otherwise impact upon the frangible element during normal operation. The frangible element may be treated, for example, by shot-peening or coating to reduce deterioration of the frangible element during normal operation.Type: GrantFiled: June 30, 2005Date of Patent: March 4, 2008Assignee: Emerson Power Transmission Manufacturing L.P.Inventors: Jon R.

Patent number: 6994195Abstract: A clutch mechanism connects a rotating shaft to an outer clutch member having a clutch keyway. The clutch mechanism permits the shaft to rotate in a normal direction and prevents the shaft from rotating in a reverse direction when the outer clutch member is rotationally fixed to the housing. A key is moveable into an engaged position with the clutch keyway to rotationally fix the outer clutch member to the housing. The key is also moveable into a disengaged position to permit the outer clutch member to rotate relative to the housing. Thus, the shaft is permitted to rotate in both the normal direction and the reverse direction. A positive, mechanical and/or visual indication of whether the shaft is capable of operating in both directions may also be included. The assembly may include a sealed interior space in common with the machine including the shaft.Type: GrantFiled: September 8, 2004Date of Patent: February 7, 2006Assignee: Emerson Power Transmission Manufacturing, L.P.Inventors: Michael Wayne Brace, Michael Hill

Patent number: 6908230Abstract: A bearing assembly wherein the inner diameter of the slotted compressible annular locking collar is provided with a protrusion which extends radially inwardly, and finger extensions of the inner ring are provided with a recessed groove which extends at least partially along the collective outer annular surface of the finger extensions. When the locking collar is disposed about the finger extensions of the inner ring, the protrusion is disposed within the recessed groove to retain the locking collar on the inner ring. The inner ring finger extensions and the locking collar are relatively sized such that when they are in their free states, the inner diameter of the protrusion is slightly smaller than the outer diameter of the recessed groove, such that the collar may be snapped over the finger extensions and into proper position on the inner ring prior to installation on a shaft. The protrusion may be an integrally formed part of the locking collar or a separate resilient member.Type: GrantFiled: December 18, 2001Date of Patent: June 21, 2005Assignee: Emerson Power Transmission Manufacturing, L.P.Inventors: James P. Johnson, Eric Puleo, Kevin Feerick

Patent number: 6746018Abstract: A multiple shaft seal arrangement positioned between a shaft and an inside diameter surface of an aperture in a wall. The multiple shaft seal arrangement has a flinger attached to the shaft with a face seal mounted to the flinger. A double lip oil seal is mounted to the inside diameter of the aperture. The flinger is positioned such that the face seal is pressed against the double lip oil seal. Accordingly, rotation of the shaft causes rotation of the flinger and face seal. This centrifugally throws contaminants, such as particulate matter, away from the aperture. The void between the face seal and the inside diameter of the aperture is filled with grease or similar substance. The combination of these elements greatly prohibits debris, moisture, particulate matter or other environmental elements from passing from one side of the multiple shaft seal arrangement to the other.Type: GrantFiled: February 21, 2002Date of Patent: June 8, 2004Assignee: Emerson Power Transmission Manufacturing, L.P.Inventors: Michael L. Lewis, Christopher A. Carrigan, Erwin R. Carrigan, Steven H. Griggs
