Description
Technical field
The present invention relates to the cooling structure field of motor, particularly relate to a kind of water-cooling structure of servomotor.
Background technology
Along with servomotor is in the long-time application of every field, it is particularly important that its cooling structure in use shows, the servomotor of current employing cooling by water mode is many, but the type of water-cooling structure has a lot, the most more complicated of structure, producing to assemble all to compare wastes time and energy, efficiency and the reasonability of assembling seem particularly important, the improvement of some assembling detail not only can be enhanced productivity, cut the waste, also effectively can improve the qualification rate of product simultaneously, in order to prevent the outflow of cooling water, generally all sealing ring is installed on the both sides of tank, but because the gap between water cooled housing and motor housing is very little, easily damage is caused to sealing ring when water cooled housing is encased in motor housing inside, very large hidden danger is brought to the operation of motor.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of water-cooling structure of servomotor, and structure is simple, and adopt sink structure simple and the cold rinse bank that differs of two ends size, water circulation is unobstructed, the damage to sealing ring when effectively preventing from assembling.
The technical solution adopted for the present invention to solve the technical problems is: the water-cooling structure providing a kind of servomotor, comprise water-cooled housing, electric machine casing and rule stator, be close to inside described electric machine casing and be furnished with water-cooled housing, rule stator is installed in described water-cooled housing, the two ends of described water-cooled housing, sealing ring is separately installed with in electric machine casing, described water-cooled housing cylindrically, its two ends embed respectively and are provided with sealing ring, in the middle part of described water-cooled housing lateral surface, the location arrangements corresponding with rule stator has inner concave, annular convex rib has been evenly arranged in this inner concave, tank is formed between adjacent annular convex rib, what in annular convex rib, side was furnished with water guide notch is waterproof rib, what in annular convex rib, bilateral symmetry was furnished with water guide notch is reinforcement, what be positioned at inner concave two ends is reinforcement, remaining waterproof rib and reinforcement are spaced layout, the water guide notch of two adjacent waterproof ribs is that opposite side is arranged, on described electric machine casing lateral surface, the position corresponding with the two ends of the inner concave of water-cooled housing has inlet opening and apopore.
Near one end overall diameter 2mm at least larger than the overall diameter of one end of close inlet opening of apopore on described water-cooled housing.
Described water guide notch is the straight line breach parallel with the tangential direction of annular convex rib, and the middle part of this straight line breach flushes with the bottom of tank.
The periphery of described annular convex rib and the inwall of electric machine casing are close to, and its two sides are that inclined-plane is connected with the bottom of tank.
Described water-cooled housing two ends respectively embed and are provided with two sealing rings, and described sealing ring size and the two ends of water-cooled housing match, and with electric machine casing inside in fitting tightly.
Described sealing ring is O RunddichtringO.
Described inlet opening and apopore lay respectively near the water guide notch place between the waterproof rib at two ends and the two ends of inner concave.
Because one end external diameter of water-cooled housing is greater than the other end, so first stretched into from the large diameter end of electric machine casing by the miner diameter end of water-cooled housing, the interference of the sealing ring of the rear inside of electric machine casing on the miner diameter end of water-cooled housing so just can be prevented.
The water guide notch of arranging that water-cooled housing misplaces can make current from one end of water-cooled housing helically S shape flow to the other end, form a complete loop, ensure that the outside of whole water-cooled housing all contacts with cold water.
beneficial effect
The present invention relates to a kind of water-cooling structure of servomotor, structure is simple, and adopt sink structure simple and the cold rinse bank that differs of two ends size, water circulation is unobstructed, the damage to sealing ring when effectively preventing from assembling.

Embodiment
Below in conjunction with specific embodiment, set forth the present invention further.Should be understood that these embodiments are only not used in for illustration of the present invention to limit the scope of the invention.In addition should be understood that those skilled in the art can make various changes or modifications the present invention, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the present invention's instruction.
As shown in Fig. 1-8, embodiments of the present invention relate to a kind of water-cooling structure of servomotor, comprise water-cooled housing 1, electric machine casing 2 and rule stator 3, be close to inside described electric machine casing 2 and be furnished with water-cooled housing 1, in described water-cooled housing 1, rule stator 3 is installed, the two ends of described water-cooled housing 1, sealing ring is separately installed with in electric machine casing 2, described water-cooled housing 1 cylindrically, its two ends embed respectively and are provided with sealing ring 4, in the middle part of described water-cooled housing 1 lateral surface, the location arrangements corresponding with rule stator 3 has inner concave, annular convex rib has been evenly arranged in this inner concave, tank 13 is formed between adjacent annular convex rib, what in annular convex rib, side was furnished with water guide notch 14 is waterproof rib 12, what in annular convex rib, bilateral symmetry was furnished with water guide notch 14 is reinforcement 11, what be positioned at inner concave two ends is reinforcement 11, remaining waterproof rib 12 and reinforcement 11 are in spaced layout, the water guide notch 14 of two adjacent waterproof ribs 12 is arranged in opposite side, on described electric machine casing 2 lateral surface, the position corresponding with the two ends of the inner concave of water-cooled housing 1 has inlet opening 5 and apopore 6.
