Abstract
PURPOSE: To obtain a good rotational balance of a queen-bee pump consisting of a pair of rotors in the form of crossed helical gears, by constituting each rotor in the form of a helical gear having at least two start points, and distributing the tooth rails appropriately around the axis of rotation of each rotor.
CONSTITUTION: Rotors 1, 2 held in mesh with each other are arranged in a casing which is formed therein with a rotor chamber having an 8-shaped cross section defined by cylinders drawn by the tooth tips of the rotors 1, 2 as shown by the outermost dotted lines in the drawing. These rotors 1, 2 are twisted along respective axes oo, oo' of rotation and shaped in the form of a helical gear of a double-start thread having a tooth rail shown by a curve QRSS'TUVABC and another tooth rail shown by a curve EFGG'HIJKLM'MNO. Here, the curve ABC is a trochoid drawn by a point A' of the tip of the counterpart gear, and the other tooth face is shaped to have a continuous contact profile defined by an arcuate curve, straight line or cycloidal curve.
