Patent number: 5062734Abstract: A method and resulting coupler for uniting two shafts to effect mutual rotation. The coupler especially accommodates two different shaft diameters and provides a longitudinally extending slit passing through an outer wall of the coupler to expedite shaft installation and removal. The method allows the coupler to be made of a single piece of material and assures proper alignment of the two coupled shafts. A groove, extending only partially into the outer wall, facilitates flexing of the coupler for shaft installation and removal. Keyways extend on an interior wall of the coupler, the formation of which is facilitated by an arcuate inner groove.Type: GrantFiled: November 8, 1990Date of Patent: November 5, 1991Inventors: David G.

Patent number: 5000612Abstract: The invention relates to an assembled driveshaft in the case of which individual driving elements, especially gears, are non-rotatingly connected to a hollow shaft, with the connection between the hollow shaft and the driving elements essentially being achieved by a force or friction locking connection between the plastically expanded hollow shaft and the elastically pretensioned driving elements. For improving the bending and torsional stiffness of the driveshaft, at least one driving element has been produced to comprise at least two toothed discs with different diameters connected to each other by a sleeve, with the sleeve either being positioned directly on the shaft to form a basis for the connection or radially spaced from the shaft between the discs.Type: GrantFiled: February 24, 1989Date of Patent: March 19, 1991Assignee: Emitec Gesellschaft fur Emissionstechnologie mbHInventor: Helmut Swars

Patent number: 4967785Abstract: A valve actuator is disclosed which is encased in a housing with a bonnet mounted at one end and an end cap on the other end. Inside, an actuator shaft is slidably mounted through a bore on a guide connected to the bonnet. A piston is slidably mounted with respect to the guide and creates a variable-volume cavity between itself and the guide. The shaft is connected to the piston by virtue of a disk which, when bolted down to the top of the shaft, puts a preload in the spring. A connecting member is placed into contact with the disk and the piston once the spring has been preloaded. The connecting member is segmented and fits between spacers which hold the spring at a distance from the disk and allow insertion of the connecting member after preloading of the spring. The spring bears on the connecting member. Pressurization of the cavity results in an overcoming of the spring force and movement of the shaft between a first and second position.Type: GrantFiled: April 27, 1990Date of Patent: November 6, 1990Assignee: Baker Hughes IncorporatedInventor: Terry G. Young
