| A method of drive decoupling, and a drive decoupling device, utilized in connecting a driving member to a driven members that is attachable to a workpiece to be rotated about a drive axis, includes a laminated plurality of flexible sheet material, attached to the driving member by at least one off axis connection and to the driven member by at least one other off axis connection circumferentially spaced from the one off axis connection, and which is torsionally rigid in a plane perpendicular to the drive axis so as to accommodate any eccentricity developed through misalignment of the driving member and driven member. The coupling device is centrally apertured so that a headstock can extend therethrough. A pair of drive decoupling devices are also provided in series by connecting the driven member of one to the driving member of another. A clamp ring securing device is also provided with two fixed positioning and holding members and one spring loaded and externally adjustable positioning and holding member; the three holding members being circumferentially spaced about the ring. | ||||||
| 202 | Method for fixing a clamping attachment on a workpiece and device for implementing the method | US779824 | 1997-01-07 | US5951025A | 1999-09-14 | Erwin Bohler |
| The method uses the actuating mechanism of the chuck of a machine tool for turning or grinding in order to pre-tension the radially acting springs of a clamping attachment by means of the jaws of the chuck. When the pre-tension is released, the springs maintain the clamping attachment on a workpiece that is mounted between centers in order to be machined. The method allows to perform automatic machining cycles on a workpiece mounted between centers, without the necessity to use a compensated chuck. | ||||||

The blanks are simple to mount and dismount and means are provided enabling a repeatable mounting position in one angular orientation only to be achieved. The blanks are firmly fixed in place on the mandrel during the carving operation, and they are simple and inexpensive to manufacture thus reducing manufacturing costs while achieving high shape accuracy. | ||||||
| 204 | Method of machining and structure of machined pinion gear | US667792 | 1991-03-11 | US5135810A | 1992-08-04 | Roland C. Smith; James S. Fisher |
| A method for machining a part with gear teeth onto an unmachined part to form drive pinion gears is disclosed. A center bore is formed at one end of the part and receives a tool center to mount the part for machining. The center bore includes a plurality of lobes which are in point contact with the lathe center, allowing adjustment between the unmachined part and the lathe center. Drive apertures are formed radially outwardly of this center bore to receive drive pins from the machine tool. Most preferably the drive apertures are slots which provide clearance, facilitating the alignment of the drive pins in the drive apertures. | ||||||
| 205 | Apparatus for monitoring the angular position of a workpiece | US426416 | 1989-10-25 | US4934882A | 1990-06-19 | James D. Phillips |
| Apparatus for monitoring or tracking the angular position of a rotating camshaft during grinding or milling of cams on the camshaft. The cams may be milled, but in the apparatus shown, they are ground by abrasive belts which are guided by actuators driven by CNC controlled motors, to obtain the desired cam contours. Monitoring is carried out by a pick-up member engageable with a locating pin on the camshaft. The pick-up member has a slot for receiving the locating pin between a locator pad and a leaf spring. The leaf spring clamps the pin against the locator pad. The pick-up member will closely follow the rotation of the camshaft despite variations in pin size, and feed back the exact rotative position of the camshaft to the CNC controlled motors consistently and accurately. | ||||||

| In a cam grinding machine, a first diaphragm chuck is provided on a spindle rotatably supported on a rocking table for clamping one journal portion of a cam shaft and a second diaphragm chuck is provided on a support spindle rotatably and slidably supported by a tailstock in coaxial alignment with the spindle for clamping another journal portion of the cam shaft. Accordingly, cam portions of the cam shaft are ground with journal portions of the cam shaft being used as a reference. | ||||||
| 207 | Driving interface for veneer chuck assembly | US65660 | 1979-08-10 | US4271881A | 1981-06-09 | George F. Hitt |
| This invention relates to a chuck assembly for use with veneer lathes. In veneer lathes, a log is rotated against a blade for stripping a thin sheet of wood called veneer. Rotation of the log against the blade is compelled by paired chuck assemblies at opposite ends of the log. Each chuck assembly includes a spindle adapter and a chuck, both for driving rotation about the axis of rotation of the log. An improved driving interface between the spindle adapter and chuck is disclosed, extending along a plane normal to the axis of rotation. The chuck has a driving interface along a plane normal to the axis of rotation. This chuck driving interface defines keys, which keys preferably extend radially from the axis of rotation and protrude outwardly interrupting the plane of the driving interface. The spindle adapter has a complementary driving interface along a similar plane normal to the axis of rotation. The spindle adapter driving interface defines mating keyways, which keyways preferably extend radially from the axis of rotation and protrude inwardly interrupting the plane of the driving interface. When the driving interfaces are juxtaposed with the keys and keyways engaged, the rotation of the lathe imparted to the spindle adapter passes through the chuck assembly. Because of the driving interface, the chuck assembly may be constructed to a smaller diameter enabling veneer to be stripped from logs turned to a small diameter. | ||||||

The wheel securing apparatus comprises a plurality of driver arms pivotally supported on a rotatable face plate. Means are provided to move the driver arms radially so that they may engage the front face of the rim of any diameter railroad wheel. The means to move the driver arms includes a movable mechanical linkage connected to each driver arm to permit their synchronous radial movement. | ||||||
| 210 | Workpiece holder | US34791873 | 1973-04-04 | US3882647A | 1975-05-13 | FLAISCHLEN EKKEHARD |
| A workpiece holder for workpieces which are to be turned and are engaged at their opposite axial ends by centering elements. An annular member of the workpiece holder has an open end bounded by three or more curved cam portions each of which extends circumferentially and from a point farthest spaced from to a point closest to the center axis of the opening. A number of gripping rollers corresponding to that of the cam portions is lodged in the opening, each associated with one of the cam portions, and the rollers define between themselves a workpiecereceiving passage coaxial with the center axis. A guide member mounts the rollers and guides the same so that they can move relative to the annular member in direction closer to and farther from the central axis, and springs are provided which permanently bias the rollers radially outwardly into engagement with the cam portions. A drive is provided for rotating the annular member about its central axis and a retarding arrangement is operable for retarding the guide member against rotation in unison with the annular member.
