Abstract

The invention discloses a self-cooling motor which comprises a stator, a rotor, a rotating shaft and a motor shell, wherein the whole motor shell is fixed on a motor base; the two ends of the motor shell are respectively provided with a bearing pedestal; and the bearing pedestals are fixed on the motor base and isolated from the motor shell. According to the self-cooling motor disclosed by the invention (comprising a motor and an engine), a routine technique is broken, the motor bearing is isolated from a motor body, and the motor bearing and the motor body have individual heat dissipation modes without mutually influencing heat dissipation effects, thereby ensuring the good heat dissipation of the bearing and the inside of the motor; and simultaneously, the designs of a cooling fan and a bearing oil box can be used for more effectively ensuring the dissipation of heat generated by operation of the motor, guaranteeing continuous work of the motor and greatly improving the work efficiency.

Description

A kind of self cooled motor

?

Technical field

The present invention relates to a kind of self cooled motor, belong to motor or mechanism of power generation technology for making field.

Background technology

The bearing of motor of the prior art (comprising motor and generator) all be fixed in the motor and with motor coil each other near; So motor when work especially at running hours; The big calorimetric that just causes bearing and coil to produce easily can't in time outwards dissipate or cooling, though adopted the multiple type of cooling in the reality so that motor can turn round continuously, but still can't guarantee the load operation of motor; Thereby cause the damage of motor easily, also buried potential safety hazard simultaneously.

Summary of the invention

The present invention is directed to the deficiency of prior art, proposed a kind of self cooled motor, this motor efficiently solves the inadequate problem of motor radiating, thereby has guaranteed the macrocyclic continuous running of motor (comprising motor and generator).

Self cooled motor of the present invention; Comprise stator, be connected to rotor and motor housing in the rotating shaft; Said motor housing overall fixed is on motor cabinet, and the two ends of said motor housing are respectively equipped with bearing pedestal, and said bearing pedestal is fixed on the motor cabinet and with motor housing and separates mutually.

Rotating shaft between said motor housing and the motor bearings be provided be used for cooling, air discharging can be with the fan of rotating shaft rotation.

Be provided with the bearing oil cylinder in the said bearing pedestal, said bearing places in the bearing oil cylinder that is marked with lubricating oil.

Said bearing oil cylinder is provided with oil filler point and oil outlet.

The outer surface of said rotor is rule or irregular male and fomale(M&F) structure.

Said male and fomale(M&F) structure is that the rectilinear direction of bossing or sunk part of bar shaped concaveconvex structure and this bar shaped concaveconvex structure of rule is parallel with the direction of axis line of said rotating shaft.

Self cooled motor of the present invention (comprising motor and generator) has been broken routine techniques, and motor bearings and motor body are separated, and they have radiating mode separately separately; Radiating effect is independent of each other; Thereby guaranteed the better heat radiation of bearing and motor internal, simultaneously, the dissipation of motor rotation heat has more effectively been guaranteed in the design of cooling fan and bearing fuel tank; Guaranteed the continuous operation of motor, operating efficiency improves greatly.

Among the figure: 1, motor cabinet; 2, fan; 3, oil outlet; 4, rotating shaft; 5, bearing pedestal; 6, oil filler point; 7, rotor; 8, motor housing; 9, bar shaped concaveconvex structure.

Embodiment

Like Fig. 1, shown in Figure 2, self cooled motor of the present invention comprises stator, is connected to rotor 7 and motor housing 8 in the rotating shaft 4; Wherein, motor housing 8 overall fixed are on motor cabinet 1, and motor housing 8 two ends are respectively equipped with bearing pedestal 5; Bearing pedestal is fixed on the motor cabinet 1 and with motor housing 8 and separates a segment distance mutually, and motor bearings is positioned at the bearing pedestal 5 that is fixed on the motor cabinet 1, simultaneously; Establish the bearing oil cylinder that is marked with lubricating oil in the bearing pedestal 5; Bearing promptly places in the bearing oil cylinder, and the bearing oil cylinder is provided with oil filler point 6 and oil outlet 3, and this design is dipped in the lubricating oil atmosphere rotation axis and bearing connecting portion; Reduce the thermal friction of crossing of rotating shaft and bearing, effectively guaranteed the normal and continuous operation of rotating shaft and bearing; Rotating shaft 4 between motor housing 8 and the motor bearings be provided be used for cooling, air discharging can be with the fan 2 of rotating shaft rotation, the two ends of motor housing 8 respectively are provided with a fan 2 respectively, one of which is used for air blast in motor; It two is used for exhausting; Form unimpeded air-flow in the motor thereby make, the setting of two fans makes motor in the running, can effectively guarantee the circulation of air in the motor body; Help the dispersion of internal body heat, the two ends of motor housing 8 can not have end cap or mesh end cap are set; As shown in Figure 3; It is parallel with the direction of axis line of rotating shaft 4 that the outer surface of rotor 7 is designed to the rectilinear direction of bossing or sunk part of bar shaped concaveconvex structure 9 and this bar shaped concaveconvex structure 9 of rule; Remove this, the outer surface of rotor 7 also can be designed as spirality concaveconvex structure or arc concaveconvex structure, and the design of this concaveconvex structure can effectively guarantee the rotor circulation of surrounding air in the running; Simultaneously; For generator, can make this concaveconvex structure play the effect of cutting magnetic line in magnetic field again, thereby more improve the operating efficiency of generator.The present invention has broken conventional technological means, and motor bearings and motor body are separated, and they have radiating mode separately separately; Radiating effect is independent of each other; Thereby guaranteed the better heat radiation of bearing and motor internal, simultaneously, the dissipation of motor rotation heat has more effectively been guaranteed in the design of cooling fan and bearing fuel tank; Guaranteed the continuous operation of motor, operating efficiency improves greatly.
