Permanent local battery system rotary electrical machinery and appliances and on vehicle permanent local battery system rotary electrical machinery and appliances system

摘要

Being the permanent local battery system rotary electrical machinery and appliances of the rotor cantilevered suspension structure whose capacity is large, before concatenating with the motive for action machine, not only axial direction and diameter direction of the rotor direction of rotation (lap direction) it offers the permanent local battery system rotary electrical machinery and appliances which can cope with also restraint sufficiently as a restraint structure of the rotor.Permanent local battery system rotary electrical machinery and appliances 1 through the bearing 9 which, provides only the shaft 7 one end side of rotor 3 in one side of rotary electrical machinery and appliances casing 2 has the rotor cantilevered suspension structure which is supported. One end the side which is not supported by the bearing of rotor shaft 7 through the flange 10 which is provided in shaft one end, shaft one end and is concatenaion of the motive for action machine possible. Rotor shaft 7 is concatenated, when the shaft of the motive for action machine and being non concatenated state, in order the axial direction and diameter direction, lap for the movement of direction to be restrained, the aforementioned flange 10 which is not supported with the bearing through the concatenated component 12 for restraint to one end aspect of casing 2.
