Abstract:
Sowohl Scheibenräder (12) als auch Felgenteile (13) sind auf eine Aufspannvorrichtung (3) aufspannbar, wobei die Fel genmitte (21) jeweils an selber Stelle liegt. Das Einspannen geschieht mittels eines Ringes (25), der Spannbacken (27) radial nach aussen gegen die innere Stirnseite (33) des Prüf körpers (12, 13) drückt, wobei gleichzeitig der Zentrierdurch messer (33) gemessen wird. Tastrollen (16, 17) ermitteln den Rundlauf, die Rundlaufdifferenz, den effektiven oberen und unteren Nenndurchmesser (56), den Seitenschlag, die effek tive Nennweite (57). Ein Taster (43) ermittelt die Planheit des Flansches (32). Durch Entriegeln eines Riegelelementes (8) kann die Aufspannvorrichtung (3) zwecks Unwuchtprüfung über eine Kugelkalotte (2) gleiten, wobei eine Luftleitung (7) in die Kalotte mündet.
Abstract:
A gage that measures the size and out of roundness of the inside and outside diameters of ring-shaped parts comprises a centerline hub body together with a free style swing gage. The centerline hub body has extensible jaws that can be adjusted to position the body within the central opening of the part. A vertically protruding cylindrical post is located at the center of the hub body and is adapted to interface with the free style swing gage. The free style swing gage comprises a pair of parallel cylindrical rods that are adapted to fit over the centerline post. On each end of parallel rods is disposed a block, each block having a probe that protrudes downward from the block and is operable to contact a surface of the part to be checked. A front block is associated with a dial indicator connected with the probe to indicate any deviations in size or diameter of the part to be checked. The free style swing gage, together with the centerline post of the centerline hub body, allows the gage to be positioned at the actual centerline of the part. The free style swing gage is easily rotatable throughout the full 360 degree circumference of the part to be checked by grasping and rotating a handle on the rear block.
Abstract:
Method and apparatus are disclosed for determining the diameter of sheet material and for setting the tension on sheet material as it is would on the reel. The diameter of a take-up reel (11) including sheet material (10) wound thereon is determined from the angle of rotation (WS) of the take-up reel, and movement of the sheet material as obtained from rotation of a circular element such as a drive roller (14) which rotates in proportion to sheet material movement. In another embodiment, the diameter of a reel is determined from the angles of rotation of the supply and take-up reels, the total amount of sheet material in the system, and the packing factor of the sheet material rewound on the take-up reel. The diameter determination may then be used to set the torque of the take-up reel, and thereby the tension on the sheet material during winding.
Abstract:
Apparatus comprising a support (37), a system of slides (3. 27, 28) movable with respect to the support (37), motors (10, 24) for displacing the slides (3, 27, 28), transducers (47, 48) adapted to provide signals indicative of the positions of the slides (3, 27, 28) and measuring means (30, 31) carried by the system of slides (3,27,28). In order to perform, accurately and quickly, measurements on different types of parts (38, 75), the system of slides (3, 27, 28) comprises a longitudinal slide (3) and two slides (27, 28) movable simultaneously and symmetrically along the same transversal directions. The measuring means comprise two measuring heads (30, 31) each of which is fixed to a relevant transversal slide (27, 28) and adapted to measure both in longitudinal and transversal directions. The measurements of the parts (38, 75) are obtained by combining the signals of the transducers (47, 48) and those provided by the measuring heads (30,31). The apparatus is particularly suitable for measurements in manufacturing shops.
Abstract:
The gauge for measuring large diameter comprises a number of measuring units. Each measuring unit includes two position elements (11, 12), a fastener (14) and a body (13). These units are disposed on a circular surface and fixed by the fasteners one by one during measuring, until the remainder gap is not enough to dispose another measuring unit. Measuring the relevant geometric parameters and calculating the diameter according to the equation (I).
Abstract:
In order to determine the size and style of a hose fitting, and the size of a hose which may be assembled thereto, a simple, easy-to-use device is provided. The device has a body (12), one end of which permits identification of various types of tapered, threaded fittings, the other end of which may be used to measure various dimensional features of a fitting or hose. By using viewing means (48-51) on the device, measuring indicia (46, 47) on the device may be quickly read.
