In order to provide it is a kind of one can be operated, easy to use, the labor-saving quick provision for disengagement of motor bearings.This hair
It is bright to adopt the following technical scheme that.
A kind of single disassembly bearing puller,
Include: column, pedestal, support member, be provided at the top of the column and take off son, the top of column has for branch
The gap for supportting electric machine main shaft end is equipped with chuck with the side of electric machine main shaft end face, has and be used in the middle part of the chuck
The screw hole of screw rod is installed, the outer end of the screw rod is equipped with handle；The pedestal is connect with column, for in the middle part of electric machine main shaft
The support supporting plate for providing support is mounted on the base.
According to the single disassembly bearing puller, the opposite two sides of the column top are provided with U-shaped gap, with motor
The gap of main shaft end face is equipped with chuck.
According to the single disassembly bearing puller, the width of U-shaped gap is greater than 1-5 millimeters of main shaft outer diameter.
According to the single disassembly bearing puller, the support supporting plate includes support supporting plate, telescopic rod, and support supporting plate is circle
The supporting plate of arc, telescopic rod are socketed to form by two casings, and the casing in outside is equipped with adjusting screw rod.
According to the single disassembly bearing puller, the outer end installation of the adjusting screw rod has the regulation handle of anti-skid chequer.
The present invention has following characteristics:
One, structure is simple, function-specific, the utility model belong to be exclusively used in disassembly the dedicated of micro-machine take off son.Using
Traditional bearing bundle, first is that the motor product of small-sized producer production, without corresponding special equipment；Second is that common son of taking off needs
Wanting two people to cooperate could dismantle.
Two, one man operation, saving of work and time, safe operation, easy to use, waits, it is only necessary to will be electric when the utility model is used
Machine is mounted on support supporting plate, and installation is in place, and using rotatable handle screw rod, a people can back off bearing.
Three, the utility model is easy to operate, saves the work used time, brings convenience to overhaul, repairing.
