Filed: 1989-11-24
Abstract: PURPOSE:To keep performance to its maximum level for a long period by giving the whole surface of one rotor, self-lubrication coating of soft material and the whole surface of the other, moderate-thickness surface treatment of hard material. CONSTITUTION:The surface of one rotor (e.g. a mail rotor 1) is given self- lubrication coating and the surface of the other rotor (e.g. a femail rotor 2) is given hard plating at a moderate thickness, then a gap between the rotors 1, 2 is made logically zero at B point and an ideal situation with no interference is brought about between the rotors. In fact, however, interference occurs because of misalignment affected by working precision of respective parts. As soft self-lubrication coating is given only to one rotor, cutoff to an optimum condition is made by the other hard plated rotor to allow a machine to be driven in high performance for a long period while maintaining a small gap and burning the rust due to rotor contact to be effectively prevented.
