The equally distributed some gussets of emitting shape, form several independences and the court that is open between outer collar, inside race and some gussets
Outer counterweight cavity, counterweight cavity rotor correct dynamic balancing when be used for configure balance clay, when rotor is in a basic balance its two
The counterweight end cap for being interference fitted and being connected as a single entity with rotating shaft is installed outside the balance correction disk at end, will not fall off balance clay,
The end face of counterweight end cap is provided with the equally distributed some counterweight ribs of emitting shape, and rotor uses duplicate removal when correcting dynamic balancing again
Method removes the weight of counterweight rib in correspondence position, rotor is reached higher precision.
The further scheme of the utility model, the Balance weight end of the rotor one or both ends, which covers, to be provided with and stator insulation end plate
And slot wedge forms labyrinth type notch with the relatively turnable dust-proof lasso of merging.
The further scheme of the utility model, the balance correction disk of described rotor one end are provided with the fan blade being connected as a single entity.
The further scheme of the utility model, described balance correction disk, counterweight end cap, dust-proof lasso and fan blade use engineering
Plastic injection is made.
The further scheme of the utility model, described balance correction disk, counterweight end cap, dust-proof lasso and fan blade use metal
Material die casting is made.
After said structure, have the following advantages compared with prior art and effect：One is due to that balance correction disk is set
There are some counterweight cavitys, it is simple and convenient using weighting procedure to add counterweight balance clay during first dynamic balance calibration, counterweight end cap
Setting not only can be will not fall off balance clay, and duplicate removal method can be used in dynamic balance calibration again in correspondence position
Remove the weight of counterweight rib, rotor dynamic balancing is reached higher precision, correction rate is fast, service life length.Two are due to
Balance weight end in rotor one or both ends is covered provided with forming labyrinth type notch with merge can phase with stator insulation end plate and slot wedge
It to the dust-proof lasso of rotation, can prevent dust, iron from cutting into the cavity of rotor, rotor failure can be prevented, it is ensured that product
Service life.Third, the balance correction disk of rotor one end is provided with fan blade, the radiating effect of stator coil can be improved, can be with
Ensure that product is continuously run.
