Abstract

PURPOSE: To measure flow with high accuracy, by forming a pair of bevel gears of the same shape and size with specific conditions and zeroing the force on the tooth surfaces.
CONSTITUTION: The rotors 1 and 2 are constituted with a pair of the bevel gears of the same shape and size in which the torsion rate i, where i=Ltanβ/Mπ, is given in a positive integer, taking the torsion angle of the bevel gear as β, height of the gear as L, number of tooth as Z, and module as M. If i=1 is taken, the torques T1 and T2 of the rotors 1 and 2 are expressed in equation I, and they are constant at the gearing position. Since T1+T2=constant and T1-T2=0 are obtained the same as above, taking 1 is 2, 3,..., the revolution is non-pulsive and the giving and receiving of energy between the both rotors is zero to keep the force on the tooth surfaces at zero. Where: Rr is the radius of tooth bottom circle, R0 is the radius of tooth tip circle Rc is the distance between the shaft center and the cycloid curve B1C1, and H(Oersted) is the center angle of the circular arc ends A1 adjacent on the tooth tip circle with the shaft center.
