ROTATIONAL LOAD COMBINATION AND AIR CONDITIONER HAVING THE SAME

摘要

PROBLEM TO BE SOLVED: To solve a new problem in a configuration for suppressing wear of a bearing with increase in a load to the bearing due to a deviation in concentricity generated from three fulcrums in three bearing parts in a structure of a rotational shaft of a rotational load combination and suppressing electric corrosion of the bearing part.SOLUTION: A metal sintered oil-retaining bearing 5 supporting a rotational shaft 1 is attached to the rotational shaft 1 of a rotor 2. The rotational shaft 1 is supported by a plurality of bearing sliding parts provided on the inner diameter side of the metal sintered oil-retaining bearing 5 and the rotor 2 freely rotates. A motor comprises a printed wiring plate 12 mounted with a drive circuit including a control circuit. The motor is formed by press-fitting a bracket 13 on a load connection side to a stator 10 after comprising the printed wiring plate 12.SELECTED DRAWING: Figure 1A
