RECEIVER FOR DEVICES FOR MEASURING PRESSURE, TENSION, SHEAR FORCES OR TORQUE AND METHOD FOR THE PRODUCTION THEREOF

摘要

1. A force transducer for devices for measuring compressive, tensile or shearing forces, having a one-piece, parallelipipedic spring element (1; 41) which is subdivided by slots and has a bearing zone (2; 42), a force initiation zone (14; 43) and a deformation zone (11, 12; 44, 45) and with which a stop (17, 18; 48, 49) operative in the loading direction and the opposite direction respectively is associated, characterized in that a) the spring element (1; 41) is constructed in the form of a downwardly extending bending beam having the bearing zone (2; 42) and the force initiation zone (14; 43) disposed laterally one beside the other ; b) the spring element (1; 41) is subdivided by a substantially U-shaped slot (6, 7, 8; 47) - into an upper deformation zone (11; 45) connecting the force initiation zone (14; 43) to the bearing zone (2; 42), - a tongue (9; 46) rigidly connected to the force initiation zone (14; 43) and - a lower deformation zone (12; 45) connecting the force initiation zone (14; 43) to the bearing zone (2; 42) ; c) the slot (6, 7, 8; 41) so extends adjacent the bearing zone (2; 42) that at that place tongue side slotted walls and bearing zone side slotted walls are disposed opposite one another at one place as an overload stop (17; 48) and at another place as an overload counterstop (18; 49) ; d) the slot (6, 7, 8; 41) is produced by the erosion process and e) the distance of the slotted walls in the zone of the stops (17, 18) is approximately 10% greater than the deflection path at rated load.
