Description

Automobile engine cooling water pump
Technical field
The utility model relates to a kind of automobile engine cooling water pump.
Background technique
The endless form of automobile engine cooling water pump through cooling liquid cooled off the motor of automobile, to guarantee the normal operation of motor.The running of traditional its impeller of automobile engine cooling water pump is through two bearings of assembling between water pump spindle and water pump cover; And in the outside of two bearings fitting tight circle respectively; The cooling waterpump of this structure is when producing, and efficiency of assembling is low, and assembling labor intensity is big.In addition, also there is the shortcoming that radially bearing capacity is poor, axial displacement is big in the water pump spindle of this structure.
Summary of the invention
The purpose of the utility model is in order to overcome the shortcoming and defect that existing technology exists, and provides a kind of simple for structure, easy to assembly, and the automobile engine cooling water pump that radially bearing capacity is good, axial displacement is little.
For realizing above-mentioned purpose; The technological scheme of the utility model is to include water pump cover and impeller; Water pump cover is provided with impeller cavity; Be provided with shaft connecting bearing in the water pump cover, described shaft connecting bearing includes the outer ring and is arranged in the outer ring and the rotating shaft coaxial with the outer ring, is provided with respectively the steel ball and the roller that are rotatably assorted with rotating shaft and outer ring between described rotating shaft and the outer ring; Described impeller interlock is installed in the rotating shaft and is positioned at impeller cavity, is provided with seal arrangement between relative impeller cavity and the shaft connecting bearing on the described water pump cover.Through this setting, adopt the shaft connecting bearing structure, greatly simplified assembling intensity, improved efficiency of assembling, and steel ball and roller have been set, make rotating shaft have the advantage that radially bearing capacity is good, axial displacement is little.
Further be provided with is that said seal arrangement is the water seal assembly; This water seal assembly includes water seal rotary packing ring and water seal static seal seat; Described water seal rotary packing ring and rotating shaft interference fit, and be contained between impeller and the rotating shaft, said water seal static seal seat sealing and fixing is arranged in the water pump cover.
Automobile supports the bearing of water pump spindle and uses grease lubrication, therefore will prevent that cooling liquid from leaking into lubricating grease and causing lubricating grease emulsification, also will prevent the leakage of cooling liquid simultaneously.Through above-mentioned setting; Water seal rotary packing ring and axle are contained between impeller and the rotating shaft through interference fit; On the water seal static seal seat housing that leans against water pump tightly; The graphite of the pottery of water seal rotary packing ring and water seal static seal seat contacts and the elastic force through spring makes graphite and ceramic seal, in water seal rotary packing ring and water seal static seal seat relative movement process, is in sealing state always, thereby reaches the purpose of sealing cooling liquid.
Further be provided with is to be provided with spilled water hole between water seal assembly and the shaft connecting bearing relatively on the described water pump cover.Through this setting, in case there is cooling liquid to leak water seal, can release from spilled water hole, prevented that cooling liquid from getting into the installation cavity of shaft connecting bearing, and destroyed bearing lubrication and parts corrosion.If still have cooling liquid to spill after motor stops, showing that then water seal damages.
The utility model has the advantages that: simple for structure, easy to assembly, and radially bearing capacity is good, axial displacement is little.
Below in conjunction with Figure of description and embodiment the utility model is done further introduction.
Description of drawings
Fig. 1 the utility model embodiment structural representation.
Embodiment
The embodiment of the utility model as shown in Figure 1; Include water pump cover 1 and impeller 2; Water pump cover 1 is provided with impeller cavity 11, is provided with shaft connecting bearing 3 in the water pump cover 1, and described shaft connecting bearing 3 includes outer ring 31 and is arranged in the outer ring 31 and the rotating shaft 32 coaxial with the outer ring; Be provided with respectively the steel ball 33 and roller 34 that are rotatably assorted with rotating shaft 32 and outer ring 31 between described rotating shaft 32 and the outer ring 31; Described impeller 2 is rotatably installed in the rotating shaft 32 and is positioned at impeller cavity 11, is provided with seal arrangement between relative impeller cavity 11 and the shaft connecting bearing 3 on the described water pump cover 1, and present embodiment sealing device is the water seal assembly; This water seal assembly 4 includes water seal rotary packing ring 41 and water seal static seal seat 42; Described water seal rotary packing ring 41 and rotating shaft 32 interference fit, and be contained between impeller 2 and the rotating shaft 32, said water seal static seal seat 42 sealing and fixing are arranged in the water pump cover 1.
In addition, be provided with spilled water hole 12 between relative water seal assembly 4 and the shaft connecting bearing 3 on the described water pump cover 1 of present embodiment.So,, can release, prevent that cooling liquid from getting into the installation cavity of shaft connecting bearing, and destroyed bearing lubrication and parts corrosion from spilled water hole in case there is cooling liquid to leak water seal.If still have cooling liquid to spill after motor stops, showing that then water seal damages.
The foregoing description is to the specific descriptions of the utility model; Only be used for the utility model is further specified; Can not be interpreted as the qualification to the utility model protection domain, the technician of related domain according to the content of above-mentioned model utility the utility model is made some nonessential improvement and adjustment all falls within the protection domain of the utility model.
