Abstract
The utility model discloses a cooling structure for the connecting flange of the oil pump of a servo motor. The cooling structure comprises a crescent gear pump and the servo motor, wherein the crescent gear pump is fixed on an oil pump mounting flange of the servo motor; an oil pump shaft of the crescent gear pump is connected with a rotor of the servo motor; and a cooling water circulating passage is arranged in the oil pump mounting flange. The cooling water circulating passage is additionally arranged on the oil pump mounting flange of the cooling structure, so that based on the heat exchange theory, the servo motor and the oil pump are better cooled under the condition of no increase of the cost, the tight locking between the servo motor and the crescent gear pump due to high temperature is avoided, the temperatures of the servo motor and the crescent gear pump are reduced, the service life of the servo motor and the crescent gear pump is prolonged, and the reactive power loss is reduced.
Description
Technical field
The utility model relates to a kind of actuating motor oil pump, the water-cooling structure of the adpting flange on particularly a kind of actuating motor oil pump (red font need be deleted).
Background technique
Existing actuating motor and crescent gear pump are most to adopt interior inserted mode to install, and this mounting type can guarantee installation precision and save the space, but this Placement has the following disadvantages:
1) because the gap of motor shaft and oil pump shaft is less, cause and to separate owing to getting rusty after having motor and oil pump long-play easily, scrap because of dismantling simultaneously thereby cause, increased the maintenance cost of equipment as motor or one of them damage back of oil pump.
Can produce heat during 2) owing to the actuating motor operation, and the mode that motor and oil pump insert in adopting connects, the temperature of motor can be directly transferred on the oil pump, causes the Sealing of oil pump to wear out, and damages easily.
3) size of the life-span of actuating motor and moment is with the temperature correlation of motor itself, and temperature is high more, and the life-span is short more, and simultaneously, the reactive loss of motor also can raise along with the rising of temperature.And the type of cooling of general actuating motor all has only air-cooled or wherein a kind of type of cooling of water-cooled, if two kinds are all done then cause the manufacture cost height of motor, and defective such as volume is big.
The model utility content
At above-mentioned the deficiencies in the prior art, the technical problems to be solved in the utility model provides a kind of cooling structure on the actuating motor adpting flange, so that can play better cooling effect.
For solving the problems of the technologies described above, the utility model adopts following technological scheme:
A kind of actuating motor oil pump adpting flange cooling structure, comprise crescent gear pump and actuating motor, described crescent gear pump is fixed on the oil pump mounting flange of described actuating motor, the oil pump shaft of crescent gear pump is connected with the rotor of actuating motor, is provided with the cooling water circulation canal in the described oil pump mounting flange.
Preferably, described actuating motor is provided with cooling fan away from an end of described crescent gear pump.
Technique scheme has following beneficial effect: this cooling structure has increased the cooling water circulation canal on the oil pump mounting flange, can not increase under the condition of cost by heat exchange principle better to actuating motor and oil pump cooling, both avoided actuating motor and crescent gear pump Yin Gaowen and killed, reduced the temperature of actuating motor and crescent gear pump again, prolong the life-span of actuating motor and crescent gear pump, reduced reactive loss.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification, below with preferred embodiment of the present utility model and conjunction with figs. describe in detail as after.Embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation.
Fig. 2 is the sectional view of oil pump mounting flange among the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail.
As shown in Figure 1, this actuating motor oil pump adpting flange cooling structure comprises crescent gear pump 1 and actuating motor 4, crescent gear pump 1 adopts interior inserted mode to be connected with actuating motor 4, crescent gear pump 1 is fixed on the oil pump mounting flange 2 of actuating motor 4, and the oil pump shaft 7 of crescent gear pump 1 is connected with the rotor 8 of actuating motor 4.Drive crescent gear pump 1 rotation when actuating motor rotates, crescent gear pump 1 is converted into pressure with mechanical energy can give hydraulic system, drive machines work through hydraulic oil.
As shown in Figure 2, be provided with cooling water circulation canal 3 in the oil pump mounting flange 2, the water inlet A of cooling water circulation canal 3 and water outlet B all are positioned on the surface of oil pump mounting flange 2.Cooling water enters cooling water circulation canal 3 from water inlet A, and flows out from water outlet B along the direction of arrow, and oil pump mounting flange 2 is cooled off.Be provided with cooling fan 5 at actuating motor 4 away from an end of crescent gear pump 1.Can make dual-cooled to actuating motor 4 by cooling water and cooling fan.
Compared with prior art, the utlity model has following advantage:
1. when cooling water during from this channel cycle, because the principle of heat exchange, the heat that is produced when actuating motor and inside engaged gear pump work will be taken away by water, thereby reduced the temperature of actuating motor, and owing to reduced the temperature of actuating motor, the reactive loss of actuating motor reduces, and energy consumption is lower, and after the temperature reduction, the longer and not increase of cost of the life-span of actuating motor.
2. since cooling water from this channel cycle, the temperature of these parts of oil pump mounting flange guarantees in lower level, thus the oil pump shaft that has reduced servo motor rotor and crescent gear pump is interlocked owing to getting rusty, and causes the probability that can't dismantle.
3. owing to there is cooling water to circulate from this cooling water circulation canal, the temperature of these parts of oil pump mounting flange guarantees in lower level, delayed axial seal aging of crescent gear pump, prolonged the life-span of inside engaged gear pump seal.
More than a kind of actuating motor oil pump adpting flange cooling structure that the utility model embodiment is provided be described in detail; for one of ordinary skill in the art; thought according to the utility model embodiment; part in specific embodiments and applications all can change; in sum; this description should not be construed as restriction of the present utility model, and all any changes of being made according to the utility model design philosophy are all within protection domain of the present utility model.
Claims (2)
1. actuating motor oil pump adpting flange cooling structure, comprise crescent gear pump and actuating motor, described crescent gear pump is fixed on the oil pump mounting flange of described actuating motor, the oil pump shaft of crescent gear pump is connected with the rotor of actuating motor, it is characterized in that: be provided with the cooling water circulation canal in the described oil pump mounting flange.
