Abstract
The utility model discloses a self-cooling motor comprising a stator, a rotor, a rotary shaft and a motor shell, wherein the whole motor shell is fixed on a motor seat, bearing seats are arranged at the both ends of the motor shell respectively, and the bearing seats are fixed on the motor seat and separated from the motor shell. The self-cooling motor (comprising a motor and a generator) disclosed by the utility model breaks a conventional technology, and separates motor bearings from a motor body, and the motor bearings and the motor body have respective heat dissipation modes and have no influence on the heat dissipation effect, thus ensuring the good heat dissipation of the bearings and the interior of the motor; simultaneously, a design of a cooling fan and a bearing oil tank can be used for more effectively guaranteeing the dissipation of the operating heat of the motor, ensuring the continuous work of the motor, and greatly increasing the working efficiency.
Description
Technical field
The utility model relates to a kind of self cooled motor, belongs 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 utility model has proposed a kind of self cooled motor to the deficiency of prior art, and this motor efficiently solves the inadequate problem of motor radiating, thereby has guaranteed the macrocyclic continuous running of motor (comprising motor and generator).
The self cooled motor of the utility model; 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.
The self cooled motor of the utility model (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.
