Abstract
The utility model discloses a cooling structure of a motor casing. The cooling structure of the motor casing comprises a casing body and a casing outer shell, and is characterized in that two ends of the outer circumferential surface of the casing body are provided with a first tool retracting groove and a second tool retracting groove, double spiral grooves which are respectively a first spiral groove and a second spiral groove are arranged between the first tool retracting groove and the second tool retracting groove, an inlet and outlet joint is arranged nearby a spiral head of the first spiral groove and a spiral head of the second spiral groove respectively, the casing outer shell is fixedly sleeved on the casing body, the inlet and outlet joints are fixedly connected to the casing outer shell and are communicated with the second tool retracting groove, a baffle block is arranged next to one of the inlet and outlet joints, and the baffle blocks are fixedly arranged in the second tool retracting groove and are in gapless with the second tool retracting groove. The cooling structure of the motor casing has the advantage that the double spiral grooves are adopted, the cooling liquid enters the casing body from an initial end of the first spiral groove and returns from the second spiral groove at the other end to an initial end of the second spiral groove, so that the cooling effect of the motor is uniform, the reliable operation of the motor is ensured, and the cooling structure has the advantages of simple structure and convenient manufacturing.
Description
Technical field
The utility model relates to a kind of structure of motor, relates in particular to a kind of cooling structure of motor case.
Background technology
As everyone knows, general motor all can generate heat when bringing onto load move, when the current density that particularly designs when motor stator winding is high, the caloric value of motor can be very large, if do not taked additional cooling mode, the heat that motor sends can make the ageing of insulation of stator winding, reduces the useful life of motor.At present, conventionally the type of cooling of motor has nature cooling, fan is forced cooling and liquid cools etc., and in some special machines, there are some special requirements, as for all-electric big bus motor, motor need to be contained in wheel hub, in industry, common way is that nature is cooling, it is lower that this can arrange the current density of stator when design of electrical motor, but can increase like this copper consumption of motor and the volume of motor, thereby increase the cost of motor, also the helicla flute of the processing of the inside at casing having, the water outlet of one end water inlet other end, but this type of cooling can cause motor one end, good cooling results other end cooling effect is poor, inhomogeneous cooling is even, affect the reliability service of motor.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of cooling even, guarantees the cooling structure of the motor case of motor reliability service.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of cooling structure of motor case, comprise casing ontology and casing shell, the place, two ends of the outer circumference surface of described casing ontology is provided with the first escape and the second escape, between the first described escape and the second described escape, be provided with double spiral groove, i.e. the first helicla flute and the second helicla flute, the first described helicla flute and the second described spiral fluted spiral head are positioned at same one end, near the first described spiral fluted spiral head and the second described spiral fluted spiral head, be respectively arranged with turnover joint, fixedly sleeved the first escape on described casing ontology and described in covering of described casing shell, the second escape and double spiral groove, described turnover joint is fixedly connected on described casing shell and is connected with the second described escape, the side of described turnover joint is provided with barrier blocks, described barrier blocks is fixedly installed in the second described escape and coordinates with the second described escape gapless.
Described casing shell be welded on described casing ontology and with described casing ontology interference fits or interference fit.
The first described helicla flute is identical with the second described spiral fluted grooved.
Turnover joint described in two is symmetrical arranged along the central axis of described casing ontology, and the barrier blocks described in two is symmetrical arranged along the central axis of described casing ontology.
The shape of the radial section of described barrier blocks is identical with the shape of the radial section of described the second escape.
Compared with prior art, the utility model has the advantages that owing to having adopted double spiral groove, cooling fluid second helicla flute to the other end from the first spiral fluted initiating terminal enters casing ontology is returned, get back to the second spiral fluted initiating terminal, make the cooling effect of motor even, avoid the defect of the poor other end good cooling results of motor one end cooling effect, guaranteed the reliability service of motor, and simple in structure, easily manufactured; In addition, owing to passing in and out the side of joint, be provided with barrier blocks, make the cooling abundant of whole casing ontology.
Accompanying drawing explanation
Fig. 1 is cutaway view of the present utility model;
Fig. 2 is the perspective view of casing ontology of the present utility model.
Embodiment
