Title: IMPROVED ELECTRICALLY POWERED HEAD TORQUE-CHECKING DEVICE
Abstract:
Provided is an improved electrically powered head torque-checking device, comprising a torque-checking platform control cabinet (1) and torque checking platform bodies (2) connected to the torque checking platform control cabinet (1) and having different ranges; each of the torque checking platform bodies (2) comprises a superimposed flange assembly (202) abutting against the electrically powered head, and a transmission center assembly, the transmission center assembly comprising superimposed driving shaft couplings (203) superimposed on each other and a magnetic-powder brake (205) controlled by the torque checking control cabinet (1) and used for braking; the transmission center assembly also comprises a planetary transmission (204) arranged between the superimposed driving shaft couplings (203) and the magnetic-powder brake (205), and the planetary transmission (204) is interlockingly connected to the superimposed driving shaft couplings (203) and the magnetic-powder brake (205); the outer side face of the outer ring gear (210) of the planetary gear (212) of the planetary transmission (204) is equipped with a plurality of pressure transducers (211) used for measuring the force along the tangential direction of the outer ring gear (210). The improved electrically powered head torque checking device has high measurement accuracy, is easy to operate, and is stable and reliable.
