Solid of revolution

Rotationskörper

Magnetoelastic force transducer characterized in that it comprises a solid of revolution (1) of soft-magnetic material provided with two substantially identically identical thin, force-sensing, cylindrical parts (2, 3) which are surrounded by series-connected, AC-current supplied magnetizing windings (4, 5) and oppositely series-connected measuring windings (6, 7), that between said thin parts there is an inwardly directed, force-absorbing inner flange or a disc (8) and an outwardly directed middle flange (9), the middle flange (9) having substantially the same outer diameter as the entire windings on the outer side of said thin parts, that the axially outer sides are porvided with outwardly extending flanges (10, 11), the outer diameter of which is at least as that of the entire windings on said thin parts, that the solid of revolution is surrounded by a tube (12) of soft-magnetic material, which tube is fixed to the outer outwardly-extending flanges (10, 11) by means of joints, capable of transmitting shearing forces, and which tube defines a norrow air gap with the outwardly extending middle flange, and that the outwardly extending flanges (10, 11) simultaneously serve a supporting surface for the ractive force.

Magnetoelastisches Kraftmeßgerät, insbesondere zur Messung von Axialkräften in rotierenden Wellen, wie bei­ spielsweise in Werkzeugmaschinen. Das Kraftmeßgerät be­ steht im wesentlichen aus einem Rotationskörper (1) aus weichmagnetischem Material mit zwei gleichen dünnen kraf­ terfassenden zylindrischen Teilen (2, 3), die von in Reihen geschalteten wechselstromgespeisten Magnetisierungs­ wicklungen (4, 5) und gegensinnig in Reihe geschalteten Meßwicklungen (6, 7) umgeben sind. Der Rotationskörper ist von einem aus weichmagnetischem Material bestehenden Rohr (12) umgeben und ist axial außerhalb der Wicklungen an dem Rotationskörper befestigt.
