摘要:
Bei einer Vorrichtung (1) zum Spannen einer Felge (2) eines Fahrzeugrades sind wenigstens vier zur Felge (2) bewegbare Spannelemente (3) vorgesehen, die Spannarme (5) und Auflagenelemente (7) mit Auflagenflächen (6) umfassen. Auf den Auflagenflächen ist ein Felgenhorn der Felge (2) auflegbar. Die Spannarme (5) sind um ihre Längsachse drehbar in den Spannelementen (3) gelagert und weisen endständig die Auflagenflächen (6) überragende Spannfinger (8) auf, die mit dem auflegbaren Felgenhorn in Spannkontakt bringbare Spannflächen aufweisen.
摘要:
An apparatus for a shaft balancing machine for fastening a balancing weight to a shaft (1) has a pincer-like device which comprises an upper and a lower pincer unit (2, 3), wherein each pincer unit (2, 3) is in the form of a two-armed lever. The lever is mounted, so as to be rotatable about a lever centre of rotation (9, 9'), on a main body (10). Each pincer unit (2, 3) has, on a first lever end (6, 6'), a receiving part (4, 5) with at least one receptacle (7, 8) for a balancing weight or a shaft. The levers are connected to one another, at the second lever ends (13, 13') thereof situated opposite the receptacles (7, 8), by way of a stroke-imparting cylinder (14). In order that the receptacles (7, 8) can be brought into radial contact with the shaft (1) by way of a stroke of the stroke-imparting cylinder (14), in each case one guide bar (11, 12) is articulated on the receiving part (4, 5) of each pincer unit (2, 3) and on the main body (10).

A protective housing (1) for a testing, measuring or production device has a protective element (14), which seals a housing opening and is held and guided by guide devices (23, 34) and can be moved into an open position by means of a drive device (37). The guide devices (23, 24) have arched sections which are outwardly curved forward and extend backwards in a straight line on an upper side of the protective housing (1). The protective element (14) comprises two flexurally stiff rectangular plates (18, 19), which have straight longitudinal sides and a curve approximating the arched sections and are connected to each other on a longitudinal side via a hinge. The guide devices (23, 24) comprise a number of guide elements guided on a guide rail (25), wherein a respective guide element is arranged on the hinge and further guide elements are arranged on both sides of the hinge. The drive device (37) drives the rearmost guide element (30) via two traction transmissions (38, 39), which have traction mechanisms running parallel to the straight section of the guide devices (23, 24).
