Description
Technical field
The present invention relates to be between a kind of rotor and base using the assembly tooling of the motor of double fulcrum sliding bearings,
In particular to a kind of motor drive terminal bearing shell installation positioning tool and localization method using double fulcrum sliding bearing motors.
Background technique
It is using double fulcrum sliding bearings between rotor and base as rotor two in some heavily loaded high-speed motors
End support, the drive end bearing of the motor is positioning sliding bearing, and the non-driven-end bearing of the motor is floating bearing；In electricity
When machine assembles, positions the bearing shell in sliding bearing and require to keep certain gap with the end thrust face on motor shaft, to avoid
After motor puts into effect, due to the automatic capturing of rotor, the axial float of generated rotor causes bearing shell and electricity
End thrust face on arbor generate close to and friction phenomenon, ultimately cause bearing shell heating damage；Therefore, it is assembled in such motor
In, how science determines that the fit-up gap between the end thrust face on motor drive terminal bearing shell and rotor is in assembly
The work of the most important thing；Existing assembly method is: using the side of measurement motor stator and rotor core length and its position indirectly
Method, to determine the position of stator ventilating duct and rotor ventilation road respectively, in the premise that stator ventilating duct is aligned with rotor ventilation road
Under, to determine the installation site of drive end axle watt；Theoretically there is no problem for this determining method, but due to stator core and
There is the error of manufacture, assembly and measurement in rotor core, often will appear in the motor stator and rotor magnetic force estimated when assembly
The heart line overlapping positions problem inconsistent with stator and rotor magnetic field center overlapping positions when motor actual motion, directly results in
The assembly preset clearance of shaft end is improper, makes motor in operation from now on, and the end thrust face and driving end at driving end occurs
Bearing shell fitting friction, directly contributes bearing shell temperature arrising caused by friction and damage.
