Abstract
The invention relates to a water cooling device of a servo motor, and the device comprises a water cooling shell body and a motor shell; a water inlet hole and a water outlet hole are arranged on the motor shell; a wire inserting stator is arranged in the water cooling shell body; the outside of the water cooling shell body is connected with the motor shell through a seal ring in a sealed way; a water guide groove on the water cooling shell body and the motor shell form a water cooling loop; and one end of the water cooling loop is communicated with the water inlet hole, and the other end of the water cooling loop is communicated with the water outlet hole. According to the water cooling device for the servo motor, the output efficiency of the servo motor is high, and the output torque and the output power are increased.
Description
Technical field
The present invention relates to motor cooling technology field, particularly relate to a kind of water cooling plant for servomotor.
Background technology
That the cooling devcie of motor of reusing at present comprises is air-cooled, oil cooling and three kinds of modes of water-cooled.In motor application, comprehensive cooling performance and Financial cost are mainly take air cooling as main.The air cooling is structurally simple, expense is cheap, easy to maintenance, these remarkable advantages have at first obtained application and development so that air cools off, still, and along with the increase of capacity motor, amount that the motor feels hot is also increasing, need to strengthen cooling and just must strengthen ventilation quantity, thereby increase draft loss, reduce electric efficiency.Water-cooling pattern is because the convection transfer rate of water is more than 150 times of control natural heat-exchange coefficient, rate of heat dissipation is high, simultaneously it does not have again pollution that the oil cooling mode may bring and inflammable, and the problems such as noise that adopt forced air cooling to produce, so obtained paying close attention to more and more widely.
In the prior art, the cooling of water-cooled machine generally is divided into two kinds of forms, a kind of is to add but device of water-air cooling at outside motor, the motor internal heat takes the empty cooler of external water to by the inner air circulatory system, and this finish with external circulating system in the heat exchange of aqueous medium, thereby constantly the motor heat is taken away; Another kind is directly to offer water channel in base inner, directly motor is cooled off, i.e. support formula water-cooled machine.But in current machine field, people grow with each passing day to the demand of high power density motor, and high power density motor is compared with common electric machine, same power output and torque, but volume is little, lightweight, noise is little, save cost.
Summary of the invention
Technical problem to be solved by this invention provides a kind of water cooling plant for servomotor, so that the delivery efficiency of servomotor improves, output torque and power output increase.
The technical solution adopted for the present invention to solve the technical problems is: a kind of water cooling plant for servomotor is provided, comprise water-cooled housing and motor housing, described motor housing is provided with inlet opening and apopore, the rule stator is equipped with in described water-cooled housing inside, and described water-cooled housing outside is connected and sealed by sealing ring and motor housing; Guiding gutter on the described water-cooled housing and described motor housing form a water cooling labyrinth, and described water cooling labyrinth one end communicates with described inlet opening, and the other end communicates with described apopore.
Described sealing ring is O shape circle.
Described water-cooled housing is provided with waterproof rib, and described waterproof rib and guiding gutter alternative arrangement arrange.
Described inlet opening and apopore are hexagonal structure.
The height of described inlet opening is higher than the height of apopore.
Beneficial effect
Owing to having adopted above-mentioned technical scheme, the present invention compared with prior art, have following advantage and good effect: the present invention utilizes sealing ring that water-cooled housing and electric machine casing are connected and sealed, and formation water cooling labyrinth, so that the motor of equal volume, can obtain larger power output and output torque, comply with the light-weighted development trend of motor.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of water-cooled housing among the present invention.
Embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment only to be used for explanation the present invention and be not used in and limit the scope of the invention.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims limited range equally.
Embodiments of the present invention relate to a kind of water cooling plant for servomotor, as shown in Figure 1, comprise water-cooled housing 1 and motor housing 2, described motor housing 2 is provided with inlet opening 5 and apopore 6, rule stator 3 is equipped with in described water-cooled housing 1 inside, described water-cooled housing 1 outside is connected and sealed by sealing ring 4 and motor housing 2, for example can be by the sealing between 4 O shape circle realization water-cooled housings 1 and the motor housing 2.Guiding gutter 21 on the described water-cooled housing 1 forms a water cooling labyrinth with described motor housing 2, and described water cooling labyrinth one end communicates with described inlet opening 5, and the other end communicates with described apopore 6.Wherein, described inlet opening 5 and apopore 6 are hexagonal structure, and the height of inlet opening 5 is higher than the height of apopore 6.
As shown in Figure 2, be designed with waterproof rib 22 and guiding gutter 21 on the water-cooled housing among the present invention, described waterproof rib 22 and guiding gutter 21 alternative arrangement settings, be designed with inlet opening and apopore on the motor housing, form a Water-cooling circulating loop between the guiding gutter of water-cooled housing and the motor housing, realize the cooling by water function of motor.
Be not difficult to find, the present invention utilizes sealing ring that water-cooled housing and electric machine casing are connected and sealed, and forms water cooling labyrinth, so that the motor of equal volume can obtain larger power output and output torque, complies with the light-weighted development trend of motor.The water-cooled housing structure of using is unique, and area of dissipation is large, makes current fully contact radiating surface, and easily processing.
