METER OF OUTPUT CHARACTERISTICS OF SPIRAL SPRINGS Russian patent published in 2017 - IPC G01L3/10 

FIELD: measuring equipment.

SUBSTANCE: meter of the output characteristics of the spiral springs further comprises magnetoelectric transducers mounted symmetrically and inverted orthogonally at the ends of the beam arms, each of which comprises a coil and a fixed coaxial permanent magnet. The windings of the coils are connected in series to the third and the fourth outputs of the electronic measuring unit, and the magnetic poles of each of the permanent magnets and coils are oriented with respect to each other in such a way that the interactions of the magnetic fields create moments aimed at balancing the torque of the beam generated by the spring under test, and the outriggers of the output shaft are fixed on the platform, on which the level in the horizontal plane of the platform, the stepping motor, the fixing module of the test spring are also installed, orthogonal to the rocker arm support. The platform is mounted on vibration-regulated suppression supports, a source of mechanical vibrations, the input of which is connected to the output of the vibration control unit.

EFFECT: increasing the accuracy of measuring the output characteristics of spiral springs.
