ABSTRACT:
Apparatus for measuring forces which are produced by an unbalance of a rotary member, the apparatus including a measuring shaft (2) which is supported in a rotary mounting (26) rotatably about its axis (23) and to which the rotary member (1) is fixed for the measurement operation, and a support device (3) having force measuring sensors (4, 5) for supporting the measuring shaft (2) on a stationary frame (6), wherein the support device (3) has an intermediate frame (7) on which the measuring shaft is supported in a mounting plane having a force measuring sensor (4), the intermediate frame (7) is supported on the stationary frame (6) by way of a further force measuring sensor (5) and by way of a first pair (11, 12) of support levers and pivots (15to18), the rotary mounting (26) is fixedly connected to a stiff holding device (29) at an axial spacing with respect to the mounting plane (8) in which the force measuring sensors (5, 6) are disposed, the holding device (29) is supported on the intermediate frame (8) by way of a second pair (13, 14) of support levers and pivots (19to22), and the support levers (11to14) are formed by stiff flat members arranged between the associated pivots (15to22).
