Description
Technical field
The utility model belongs to rotor axle sleeve installing area, more particularly to a kind of rotor axle sleeve interference heat installation auxiliary dress
Put.
Background technology
The hot mounting process of rotor axle sleeve is influence canned motor pump rotor axle sleeve heat installation success rate and hot installation quality one
Individual key factor.Mainly the heat installation magnitude of interference including rotor axle sleeve, heat install temperature to the hot mounting process parameter of rotor axle sleeve
And the hot set-up time.Under conditions of the heat installation magnitude of interference is certain, heat installation temperature determines the heat installation gap of rotor axle sleeve,
When heat installation temperature determines, the hot set-up time finally determines the complexity of rotor axle sleeve heat installation, is to influence armature spindle
The key factor of set heat installation success or not.In actual production, usually there is hot mounting process parameter and select improper and make rotor
Axle sleeve is prematurely bound round in rotor surface, causes hot install failure.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of hot installation auxiliary device of rotor axle sleeve interference, can be with
The bulging gap of rotor axle sleeve and rotor is adjusted, it is effective to extend the hot set-up time allowed, avoid rotor in hot installation process
Axle sleeve is prematurely bound round in rotor surface, while is adapted to the installation of the rotor axle sleeve of different size.
In order to solve the above technical problems, technical scheme is used by the utility model:A kind of rotor axle sleeve interference heat peace
Servicing unit, including vacuum heat-preserving stove and heat-insulation layer are filled, the heat-insulation layer is arranged on rotor axle sleeve outer surface, including two supports
Block, the distance of two support blocks be can adjust, and rotor axle sleeve is placed in support block.
In preferable scheme, positive stop lug boss is set in the support block.
In preferable scheme, including limiting plate, limiting plate are horizontal " L " shape, and limiting plate is arranged in support block, limiting plate
It is connected by adjusting screw with support block.
In preferable scheme, the distance of the inner side of the support block and the inwall of rotor axle sleeve is 0.5 ~ 0.8mm.
In preferable scheme, the heat-insulation layer outer surface sets thermocouple.
In further scheme, the thermocouple arranges three layers in heat-insulation layer outer surface vertical direction upper, middle and lower, each layer
Four are evenly arranged in circumferencial direction.
A kind of hot installation auxiliary device of rotor axle sleeve interference provided by the utility model, the distance of two support blocks is adjustable
Section, the distance between support block is adjusted to diameter after the thermal deformation of rotor axle sleeve, so as to be by rotor axle sleeve internal diameter
It is no to judge heat distortion amount with side superimposed in support block, so as to adjust the bulging gap of rotor axle sleeve and rotor.The guarantor of setting
Warm layer effectively extends the hot set-up time of permission, avoids rotor axle sleeve in hot installation process from prematurely binding round in rotor surface.It is excellent
In the scheme of choosing, the positive stop lug boss of setting can ensure the axis of rotor axle sleeve and the centerline of support block in same straight line
On.The limiting plate of setting can be adjusted according to the rotor axle sleeve of different-thickness, to adapt to the heat of different size rotor axle sleeve
Installation.
