Abstract
The utility model relates to a novel cooling structure of an AY oil pump bearing chamber. The structure comprises: a pump shaft sheathed with a front bearing body, wherein a bearing oil chamber is formed between the pump shaft and the bearing body. The structure is characterized in that a pump shaft in the bearing oil chamber is wound with a coil pipe, and the inlet and the outlet of the coil pipe respectively pass out of the front bearing body to be connected with a cooling water tank outside the front bearing body. The advantages include: simple structure, easy casting, low cost, good effect of the coil pipe in the bearing oil chamber in direct cooling, and avoidance of the problem that water enters the bearing oil chamber due to cast defects.
Description
Technical field
The utility model relates to a kind of bearing chamber cooling structure of water pump, particularly a kind of novel cooling structure of AY oil pump bearing chamber.
Background technique
The AY oil pump can be used the higher occasion of some temperature usually, and shown in Figure 1 is the structure of present AY oil pump.Because on bearing support 2, reserved the cavity 5 of cooling chamber on its bearing chamber 1 structure.When the high occasion of temperature need be cooled off, just can cool off bearing chamber to cavity through adding cooling liquid.But the common more complicated of such structure is cast a cavity, and will be provided with cooling chamber gland 4 at the opening of cavity on bearing support when not only will cast, O type circle 3 waits other parts, and installs also cumbersome.Also have plenty of, if cooling chamber when casting defective words the situation that sand holes etc. are leaked also appears easily, so just mean in the oil that bearing is to move non-lubricating status under probably, scraps most probably if cooling water mixes.Because cavity is 1 outside in the grease chamber, is not direct cooling,, can not be used for too high temperature usually so the effect of cooling is also good inadequately.So in order to solve the difficult technical problem of bearing chamber cooling, structural improvement has been carried out in this creation.
The model utility content
The purpose of the utility model is to solve AY oil pump bearing chamber cooling structure complicacy, and cooling effect is good inadequately, the casting difficulty, and the problem that casting defect causes the water inlet of bearing grease chamber appears easily.
The utility model is achieved in that the novel cooling structure of AY oil pump bearing chamber; Comprise: be arranged with the fore bearing body on pump shaft, the pump shaft; Wherein, Form the bearing grease chamber between pump shaft and the bearing support, it is characterized in that: on the indoor pump shaft of bearing oil, be wound with coil pipe, the import of this coil pipe passes the fore bearing body respectively with outlet and is connected with the cooling water tank of fore bearing external.
The material of said coil pipe is a copper.
The utility model advantage is: simple in structure, casting is easy, and cost is low, and is respond well through directly cooling off at the indoor coil pipe of bearing oil, has avoided causing because of casting defect the problem of bearing grease chamber water inlet.
Description of drawings
Fig. 1 is the prior art constructions schematic representation.
Fig. 2 is the structural representation of the utility model.
Embodiment
Shown in Fig. 2 is a kind of novel cooling structure of novel AY oil pump bearing chamber; Comprise: be arranged with fore bearing body 12 on pump shaft 11, the pump shaft, wherein, form bearing grease chamber 13 between pump shaft and the bearing support; Remove the cavity on traditional fore bearing body; Corresponding cooling chamber gland, O type circle etc. also can be cancelled, and structure is simplified greatly.Owing to be not provided with cavity, can not produce the problem that casting defect causes the water inlet of bearing grease chamber yet.Then with heat-conducting property preferably bronze pan tube 14 directly dish be through on the pump shaft, the import 15 of this coil pipe with export 16 and pass the fore bearing body respectively and be connected with the cooling water tank of fore bearing external.The Security of bronze pan tube and thermal conductivity all the cast iron cavity than casting are good, have improved the radiating and cooling effect.
During use, the cooling liquid of cooling water tank gets into from import, and the pipeline flow-direction outlet along coil pipe finally enters cooling water tank from outlet again.Because the temperature of the cooling liquid in the coil pipe is lower than the oil temperature of bearing grease chamber, so cooling liquid is not being stopped in the flow process of pump shaft, fully absorb the inner high temperature in grease chamber, the cooling liquid that temperature raises is discharged from the outlet port, thereby plays the effect of cooling.
Below only expressed the mode of execution of the utility model, it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model patent scope.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.Therefore, the protection domain of the utility model patent should be as the criterion with accompanying claims.
The utility model advantage is: simple in structure, casting is easy, and cost is low, and is respond well through directly cooling off at the indoor coil pipe of bearing oil, has avoided causing because of casting defect the problem of bearing grease chamber water inlet.
Claims (2)
1.AY the novel cooling structure of oil pump bearing chamber; Comprise: be arranged with the fore bearing body on pump shaft, the pump shaft; Wherein, Form the bearing grease chamber between pump shaft and the bearing support, it is characterized in that: on the indoor pump shaft of bearing oil, be wound with coil pipe, the import of this coil pipe passes the fore bearing body respectively with outlet and is connected with the cooling water tank of fore bearing external.
2. the novel cooling structure of AY oil pump bearing chamber according to claim 1 is characterized in that: the material of said coil pipe is a copper.
