Abstract
The utility model discloses an automobile water pump assembly with a sleeved impeller, comprising a belt wheel (1), a water pump body (2), a water pump shaft (3), a water sealing assembly (4), and an impeller (5), wherein the impeller (5) is formed by combining a tooth-shaped impeller sleeve (51) and a plastic impeller body (52); the tooth-shaped impeller sleeve (51) is sleeved between the water pump shaft (3) and the plastic impeller body (52). The tooth-shaped impeller sleeve (51) has a structure with a radial tooth shape (53) and an axial groove shape (54). In the utility model, the engagement and groove type combination between the tooth-shaped impeller sleeve and the plastic impeller body are firm, as well as the adhesive force and the holding force are strong, the phenomena of separation, slipping and axial play of the plastic impeller body and the tooth-shaped impeller sleeve cannot occur even if the impeller is under the actions of a centrifugal force and an axial thrust generated when the water pump works, thereby efficiently prolonging the service life of the water pump; moreover, the processing technique for the tooth-shaped impeller sleeve is simple, and the production efficiency thereof is high, so that the market competitiveness of the water pump is increased.
Description
Technical field
The present invention relates to a kind of motor car engine cooling recirculation system, specifically relate to a kind of auto pump assembly.
Background technique
At present, the impeller material used of auto pump assembly mainly contains three kinds in cast iron, steel plate and plastics.Wherein: the advantage of cast iron impeller is the restriction that part does not receive leaf wing shape, and shortcoming is that manufacturing efficiency is low, and the finished part rate is also low, and deficiency in economic performance is also because cast iron own wt and goods balance, to certain influence is arranged in working life of water pump.The advantage of steel plate impeller is in light weight, and shortcoming is repeatedly moulding, and technology is loaded down with trivial details, needs following process, poor dimensional stability.The advantage of plastic impeller is in light weight, and is high temperature resistant, corrosion-resistant, and dimensional stability is good, extensively adopted by many MANUFACTURERs at present.
The water pump complement that plastic impeller is installed all is earlier with behind impeller set and the impeller body (plastics) molding and forming in the lump, through press-fiting impeller body (plastics) and impeller set is connected on the water pump spindle.Impeller set generally adopts low-carbon steel material to process, and the adhesion during for the increase plastic shaping adopts straight burr or the processing of twill annular knurl usually with the impeller set cylindrical that the plastic impeller body directly contacts.But because the degree of depth of annular knurl is more shallow; The adhesion that causes the plastic impeller body is with to hold power tightly relatively poor, and in the process of using, the plastic impeller body separates with impeller set, skids, the phenomenon of axial float happens occasionally; Cause water pump early failue, the user complains constantly.
Summary of the invention
The object of the invention is intended to overcome above-mentioned deficiency, and the adhesion between a kind of impeller body and the impeller set is provided and holds the stronger impeller set type water pump complement of power tightly.
The object of the invention realizes through following technological scheme: a kind of impeller set type auto pump assembly; Comprise belt pulley, water pump body, water pump spindle, water-sealed component, impeller; Said impeller is constituted by profile of tooth impeller set and plastic impeller body, and this profile of tooth impeller set is sleeved between water pump spindle and the plastic impeller body.Said profile of tooth impeller set has radially profile of tooth and axial bathtub construction.
After adopting structure of the present invention; Because the profile of tooth impeller set combines firmly with engagement and slot type between the plastic impeller body, adhesion and the power of holding tightly are stronger, the plastic impeller body separates with the profile of tooth impeller set, skids, the phenomenon of axial float even impeller under the effect of the centrifugal force of pump working generation and end thrust, can not occur yet; Thereby effectively prolonged the working life of water pump; And the processing technology of profile of tooth impeller set is simple, and manufacturing efficiency is high, has also just improved the market competitiveness of water pump.
Description of drawings
Below in conjunction with accompanying drawing and mode of execution the present invention is made further detailed description.
Fig. 1 is the structural representation of impeller set type auto pump assembly.
Fig. 2 is the structural representation of the profile of tooth impeller set among Fig. 1.
Fig. 3 is the B-B sectional view of Fig. 2.
Embodiment
Can know with reference to Fig. 1, Fig. 2, Fig. 3; Impeller set type auto pump assembly of the present invention; Comprise belt pulley 1, water pump body 2, water pump spindle 3 (having contained bearing), water-sealed component 4, impeller 5; Said impeller 5 is constituted by profile of tooth impeller set 51 and plastic impeller body 52, and this profile of tooth impeller set 51 is sleeved between water pump spindle 3 and the plastic impeller body 52.Said profile of tooth impeller set 51 has radially profile of tooth 53 and the axially structure of flute profile 54.
Wherein, an end of water pump spindle 3 is equipped with belt pulley 1, and its other end is equipped with water-sealed component 4 and impeller 5, and said impeller 5 adopts profile of tooth impeller set 51 and 52 molding and forming of plastic impeller body to constitute.Even impeller of the present invention is under the effect of centrifugal force that pump working produces and end thrust; Can not occur that the plastic impeller body separates with impeller set, skids, the phenomenon of axial float yet, can prolong the working life of water pump effectively, and the processing technology of profile of tooth impeller set be simple; Manufacturing efficiency is high; The impeller set of present this structure is used on multiple water pump complement, receives domestic and international client's favorable comment deeply.
Claims (2)
1. impeller set type auto pump assembly; Comprise belt pulley (1), water pump body (2), water pump spindle (3), water-sealed component (4), impeller (5); It is characterized in that: said impeller (5) is constituted by profile of tooth impeller set (51) and plastic impeller body (52), and this profile of tooth impeller set (51) is sleeved between water pump spindle (3) and the plastic impeller body (52).
2. impeller set type auto pump assembly as claimed in claim 1 is characterized in that: said profile of tooth impeller set (51) has radially profile of tooth (53) and the axially structure of flute profile (54).
