摘要： An object of the present invention is to provide a rotor of a fluid machine in which the rotor can be made light in weight and moment of inertia of the rotor can be reduced and the rotor can be easily balanced in its rotating direction. In this rotor of a fluid machine, a fluid is compressed and pumped by a pair of rotors engaged with each other. A hollow portion is formed within a tooth stripe portion of one rotor. A thickness forming portion for a balance correction is formed in an opening portion of this hollow portion to balance the rotor in its rotating direction and is projected on an inner circumferential side of the hollow portion.

摘要： A cast screw rotor has an opened lightening or reduced weight hole formed inside each thread portion. The opened hole is formed along torsion of the thread portion, and a shaft is inserted into an axial hole. The screw rotor is manufactured by a method in which each of the thread portions and the axial hole are formed on the basis of the reduced weight hole.

摘要： A belt type nonstep variable speed pulley and gear mechanism conveys an engine rotational driving force towards an auxiliary machinery in a vehicle while changing engine speeds. It includes an axle, a fixed flange unitarily rotatable and fixedly mounted in an axial direction which extends along the axle, a movable flange unitarily rotatable with the axle and movable in the axial direction. The movable flange has one side face arranged against the fixed flange. The variable speed pulley device also has a belt provided between the fixed flange and the movable flange, a cam member having a predetermined cam face which is pressed by thrust force in the axle direction for moving the movable flange, a fixed member arranged against an other side face of the movable flange and unitarily rotatable with the axle, and a flyweight arranged between the fixed member and the movable flange so as to contact with and press the cam face by centrifugal force. The cam face has a face angle which is formed between the cam face and the axle so as to become gradually larger in a direction in which the centrifugal force works. The changing angle of the cam face satisfies properties of the auxiliary machinery which comprise high speed changing points and/or fixably maintained rotational frequencies.
