Description

Full runner circulation cooling electromechanical shell

Technical field

This utility model relates to a kind of electromotor cooling system, belongs to design of electrical motor and manufactures field.

Background technology

In the exploitation to motor product, especially in the exploitation of heavy-duty motor, the requirement of cooling system is significantly high, and especially best with the effect of water-cooled in the various types of cooling, also the most practical.It is the current heat taking away motor work generation as much as possible in pipeline as much as possible for making when pump power is certain, it is necessary to increase the contact area of current and motor as much as possible.Under the premise that cannot embed pipeline in casing, can only hole to replace pipeline (referring to accompanying drawing 1, accompanying drawing 2) in casing.Owing to the hole in casing is through hole, cool down water during cooling and only just directly flowed away by a runner 4, cooling effect extreme difference；Current necessarily pass the position that casing contacts with forward and backward end cap simultaneously, if sealing effectiveness is bad, water penetrates into motor internal or outside likely via the gap of casing with forward and backward end cap, affect sealing effectiveness, motor performance is impacted, in some instances it may even be possible to parking of breaking down, short circuit motor damage, electric shock and other safety accidents.

Summary of the invention

What the purpose of this utility model was in that to overcome disadvantages mentioned above and provided a kind of can carry out effectively cooling and the excellent full runner circulation cooling electromechanical shell of water resistance to motor.

The technical solution of the utility model: a kind of complete hydronic motor housing of runner, hold casing therein including by motor stator and rotor, be arranged on the matched drive end bearing bracket in casing one end, be arranged on the rear end cap that the casing other end is matched, the axially arranged runner having Cooling Water to flow in described casing, described runner quantity is even number bar；The processing of described casing two ends has the kidney slot of runner quantity half, and two adjacent channels are connected by every kidney slot, and the location dislocation of the kidney slot of casing left end and right-hand member is arranged；Described runner has one be divided into two sections coaxial but the blind hole disconnected, respectively through coming in and going out, water channel is connected with outlet, water inlet, and all the other runners are all through hole.

The above-mentioned hydronic motor housing of full runner, wherein: be additionally provided with two O-ring seals, be separately positioned on described drive end bearing bracket, rear end cap in the annular groove left.

The above-mentioned hydronic motor housing of full runner, wherein: O-ring seal is provided with the sealing ring kidney slot corresponding with kidney slot in casing.

The above-mentioned hydronic motor housing of full runner, wherein: described O-ring seal material is silicone rubber.

This utility model is compared with prior art, runner both sides of the present utility model adopt kidney slot to link up, the location dislocation of kidney slot is arranged, runner has one be divided into two sections of blind holes that are coaxial but that disconnect to be connected with outlet, water inlet by the water channel that comes in and goes out, and all the other runners are through hole, this means that cooling water enters runner from water inlet until outlet must go through all runners, this just makes, and the walking path of cooling water is the longest, cooling-down effect best, reaches the purpose of temperature with high efficiency；The plasticity utilizing silicone rubber is good, the feature of good airproof performance, adopts silicone rubber O-ring seal effectively to be sealed by runner, adds and be provided with the sealing ring kidney slot corresponding with kidney slot in casing in O-ring seal, and water resistance is excellent.

Detailed description of the invention

Below in conjunction with accompanying drawing and preferred embodiment, to according to the hydronic motor housing detailed description of the invention of full runner, structure, feature and the effect thereof that the utility model proposes, describe in detail as after.

The schematic diagram of motor water cooling system of the prior art is shown in shown in Fig. 1, Fig. 2, it includes motor stator and rotor being held casing 2 therein, being arranged on casing 2 two ends the drive end bearing bracket 1 coordinated with casing, rear end cap 3, the axially arranged runner 4 having Cooling Water to flow in described casing 2, cooling down water when having a disadvantage in that cooling only just directly to be flowed away by a runner 4, cooling effect is poor；Two ends seal only with drive end bearing bracket 1, rear end cap 3 simultaneously, and sealing effectiveness is poor, and easily infiltration enters motor internal.

The hydronic motor housing of full runner of the present utility model, Fig. 3 is casing side view of the present utility model, on prior art basis, runner 4 quantity is particularly configured to even number bar, it is preferred to 16；The processing of casing 2 two ends has the kidney slot 7 of runner 4 quantity half, it is preferred to 8, two adjacent channels 4 are connected by every kidney slot.Casing 2 left end and the location dislocation setting of the kidney slot 7 of right-hand member, number by 1～16 by runner 4, if the kidney slot 7 of casing 2 left end connects 1-2,3-4,5-6 ..., 15-16, the kidney slot 7 of right-hand member then connects 2-3,4-5,6-7 ..., 16-1；As shown in Figure 4, described runner 4 has one be divided into two sections coaxial but the blind hole disconnected, respectively through coming in and going out, water channel 8 is connected with outlet, water inlet, and all the other runners 4 are all through hole.

Simultaneously, it is respectively kept with annular groove in drive end bearing bracket 1, rear end cap 3, and an O-ring seal 5 good fit with groove is respectively set, connected mode can adopt chimeric, gluing, it is preferably glue bonding, the structure of O-ring seal 5 is as it is shown in figure 5, be provided with concentric multiple-sealed circle kidney slot 6.Fig. 6, Fig. 7 are that drive end bearing bracket 1 of the present utility model coordinates schematic diagram with O-ring seal 5, and rear end cap 3 coordinates in like manner with O-ring seal 5.

Principle of the present utility model: if that runner 4 disconnected is No. 1 runner, the water channel 8 that so comes in and goes out two of No. 1 runner connects with extraneous outlet, water inlet respectively, water inlet flows to kidney slot 7 by half section of No. 1 runner, enter back into No. 2 runners, No. 3 runners are entered again through kidney slot 7, by that analogy, finally flow back to No. 1 runner from No. 16 runners, from another half section of outflow of No. 1 runner, that is, cooling water travels through whole 16 runners, and walking path is long, and its cooling performance is played completely.Meanwhile, cooling water, plus multiple-sealed circle kidney slot 6 thereon, can effectively be fettered, seepage problem will not occur by O-ring seal 5.

The above, it it is only preferred embodiment of the present utility model, not this utility model is done any pro forma restriction, any without departing from technical solutions of the utility model content, any simple modification, equivalent variations and modification above example made according to technical spirit of the present utility model, all still falls within the scope of technical solutions of the utility model.
