Abstract
An axial wind cooling motor is provided, wherein a ventilation hole is arranged near a heat emission fan end of the motor axis, and the depth of the ventilation hole and the lower bearing end cover of the motor are consistent. A hollow guide duct and a motor axis are connected through a connection strap, and the outside diameter d of the hollow guide duct is smaller than the inside diameter D of the ventilation hole. A thermovent is arranged between a fan equipped on the motor axis and a bearing end cover on the motor. When the motor is working, the motor fan rotates, and the air enters from the inlet of the hollow guide duct, then enters the motor axis through the exit of the hollow guide duct. Due to the air ventilation hole of the motor axis as the closed structure, air only flows from the lower bearing end cover to the upper bearing end cover, then flows out through the hollow guide duct, therefore the air discharges the heat generating when the upper and lower bearings operate to the outside of the motor, which prevents the bearings and the motor rotor from damaging because of the rising temperature. Due to no change of the connecting part of the motor axis and other devices, the corresponding change of the other device because of the corresponding motor is not required, thereby reducing the producing cost of the whole machine and the working intensity of the workers, advancing the using range of the motor.
Description
One: technical field
The present invention relates to a kind of motor with air cooling, particularly the motor of axle air cooling.
Two: background technology
The motor of the axle air cooling in the prior art, normally motor shaft is opened a straight-through circulation of air hole, motor is in the process of work, turn round by the radiator fan in the motor, air is flow through in motor shaft circulation of air hole, thereby the heat that bearing is produced during with motor rotation is taken away, reduce the temperature of bearing, prolong the useful life of bearing, because whole motor shaft is hollow through type, other corollary equipment that is connected with motor like this must be provided with ventilating system, thereby causes complete equipment manufacturing cost and installation strength to increase, and the use of motor simultaneously also has certain limitation.
Three: summary of the invention
The objective of the invention is to: design a kind of motor shaft and be the interior circulated air type of cooling, and do not influence the motor that is connected with miscellaneous equipment, thereby reduce the production cost of equipment, reduce installation strength, improve the scope of application of motor.
The present invention adopts following structure to realize above-mentioned purpose, the radiator fan end that leans at motor shaft is opened the hole of a circulation of air, the degree of depth in circulation of air hole is consistent with motor lower bearing end cap, in the circulation of air hole of axle, the hollow guide duct is installed, hollow guide duct and motor shaft couple together by brace, the outside diameter d of hollow guide duct has thermovent less than the inside diameter D in circulation of air hole between motor shaft installation fan and motor top bearing cover.
Adopt as above structure, other structure in the motor remains unchanged, machine operation constantly, electric motor fan rotates, air is entered by the import of hollow guide duct, outlet by the hollow guide duct enters in the motor shaft then, because the circulation of air hole of motor shaft is a closed type structure, air can only be flowed by the bearing cap place that makes progress, lower ball cover place, flow out by thermovent then, form flowing of air like this, thereby the heat that is produced when metal (upper turned round is discharged the motor outside, prevent that bearing and rotor Yin Wendu from raising and damage, because motor shaft and the part that connects do not have any change, also just do not need miscellaneous equipment to make corresponding change, thereby reduced the production cost and the working strength of workers of complete equipment, improve the scope of application of motor because of adapting to motor.
Four: description of drawings
Fig. 1 is a sectional structure chart of the present invention
Five: embodiment
As shown in Figure 1, this new structure comprises: motor stator 14, rotor 15, motor housing 16, motor shaft 1, upper end cover 13 and bottom end cover 5, hollow guide duct 8 etc., on the radiator fan 2 of motor shaft 1, have circulation of air hole 3, circulation of air hole 3 extends to bottom end cover 5 places of motor shaft 1 always, air inlet 6 in circulation of air hole 3 is welded with brace 7, hollow guide duct 8 is installed in circulation of air hole 3, the air inlet 9 and the brace 7 of hollow guide duct 8 are welded to connect, the air outlet 10 of hollow guide duct 8 surpasses or equals lower bearing 11, has louvre 12 between the position of motor shaft 1 installation fan 2 and upper end cover 13.Radiator fan 2 rotates when motor rotation, air is entered into bottom end cover 5 positions in circulation of air hole 3 by hollow guide duct 8, and then it is mobile to louvre 12 by circulation of air hole 3, discharge outside the axle by louvre 12 at last, the heat that produces during with 4 runnings of upper bearing (metal) 11 and lower bearing during air flows is taken away, reduce the temperature rise when bearing moves, prolonged the useful life of axle.
Claims (3)
1. motor with air cooling, it is characterized in that: the radiator fan end that leans at motor shaft is opened the hole of a circulation of air, the degree of depth in circulation of air hole is consistent with motor lower bearing end cap, the hollow guide duct is installed in the circulation of air hole, hollow guide duct and motor shaft couple together by brace, the outside diameter d of hollow guide duct has thermovent less than the inside diameter D in circulation of air hole between motor shaft installation fan and motor top bearing cover.
2. motor with air cooling according to claim 1 is characterized in that: the axle thermovent can be one and also can be a plurality of.
