Abstract

The invention discloses a method for preventing bearing bush heating when an air cooling motor is matched with a nylon pin coupler. When the nylon pin coupler is used, a hole is drilled at the axis of a nylon pin of the coupler, a screw penetrates the hole, a gasket is sleeved on the screw, a nut is screwed on the screw, and two halves of the coupler are pulled together. When the air cooling motor operates, radial movement, towards a fan vane inlet air direction, of a motor rotor is limited, contact friction of a shaft shoulder and the bearing bush end face is avoided, and heating is avoided. The method is applicable to air cooling motors using nylon pin couplers and the air cooling motors using similar couplers, excessive movement of motor rotors can be prevented after modification, and bearing bush heating can be avoided.

Description

Ventilated machine and nylon latching formula coupling prevent the method for bearing shell heating when supporting
Technical field
The present invention relates to ventilated machine and nylon latching formula coupling.
Background technique
At present, the type of cooling of general large-sized wind cooling motor, be that impeller is installed on motor shaft, and impeller is synchronizeed with rotor and rotated the generation air quantity, carries out the motor cooling itself.Due to fan impeller structure and both sides pressure reduction, easily cause rotor to move to blower fan impeller inlet wind direction.Now cause the shaft shoulder and the friction of bearing shell end contact, bearing shell is easy to heating, causes damage.
During current machine operation, mostly by means of coupling and working machine, link.In the power transmission of high-speed overload, the relative deflection of diaxon and displacement are that difficulty is avoided, for example, so multiplex elasticity movable coupling (be called for short elastic coupling flexible coupling, nylon latching formula coupling), utilize the resiliently deformable of elastic element to compensate deflection and the displacement of diaxon.
The problem relevant with the present invention is, when using nylon latching formula coupling, although compensated deflection and the displacement of diaxon by resiliently deformable, can't the limiting motor rotor to the moving radially of blower fan impeller inlet wind direction, do not eliminate the easily problem of heating of bearing shell.
Summary of the invention
While in order solving, using nylon latching formula coupling, to prevent that the ventilated machine rotor movement from crossing a bearing shell heating problem, to the invention provides a kind of ventilated machine and nylon latching formula coupling and prevent the method that bearing shell generates heat when supporting.
A kind of ventilated machine and nylon latching formula coupling prevent the method for bearing shell heating when supporting, it is characterized in that, while using nylon latching connection formula axial organ, at first bore hole at the nylon embolus bearing pin heart of coupling, penetrate screw rod in hole, overlap upper gasket on screw rod, the nut of screwing on, the two halves of coupling are pulled in together; When ventilated machine is worked, the limiting motor rotor moves radially to blower fan impeller inlet wind direction, thereby avoids the shaft shoulder and the friction of bearing shell end contact, no longer heating.
The present invention is applicable to use the ventilated machine of nylon latching coupling, also can be used for the ventilated machine of similar coupling.Prevented after transformation that rotor from moving position, avoids causing the generation of bearing shell heating accident.
The accompanying drawing explanation
Fig. 1 is the schematic diagram of the embodiment of the present invention.
Marginal data, 1-draught fan impeller, 2-bearing shell, 3-rotor, 4-nylon latching 5-screw rod, 6-packing ring, 7-nut, 8-coupling.
Embodiment
As shown in Figure 1, a kind of ventilated machine and nylon latching formula coupling prevent the method for bearing shell heating when supporting, it is when using nylon latching connection formula axial organ 8, at first hole on nylon latching 4 center drills of coupling 8, penetrate screw rod 5 in hole, on screw rod 5, cover upper gasket 6, the nut 7 of screwing on, be pulled in coupling 8 two halves together; When ventilated machine is worked, limiting motor rotor 3 moves radially to draught fan impeller 1 import wind direction, thereby avoids the shaft shoulder and bearing shell 2 end contact friction, no longer heatings.
