Abstract
The utility model relates to a lightweight automobile cooling water pump, which comprises an impeller, a water pump body, a bearing, a rotation axis and a belt pulley. The impeller is arranged on the front end part of the rotation axis, the belt pulley is arranged on the back end part of the rotation axis, and the water pump body is arranged on the rotation axis through the bearing; and the cooling water pump is characterized in that the rotation axis is formed in the middle part of the belt pulley through pressing. Compared with the prior art, the cooling water pump has the advantages that the belt pulley is integrated with the rotation axis through the pressing; and therefore, the working procedure for processing an axis is cut off, opening mould is directly carried out without mechanical workout, mould cost is lower, production rate is high, the accuracy of the mould is easily controlled, repair rate is small and the weight of the water pump is greatly reduced.
Description
Technical field
The utility model relates to a kind of engine cooling water pump, relates in particular in a kind of being applied to, the light-type cooling waterpump in the light automobile.
Background technique
With reference to figure 1, traditional automobile cooling water pump comprises water pump body 2a, impeller 5a, bearing, rotatingshaft, mechanical seal 4a, belt pulley 1a, wherein, bearing and rotatingshaft are integral piece, be shaft connecting bearing 3a, assembly relation is: shaft connecting bearing 3a is press-fitted among the water pump body 2a, the axle that mechanical seal 4a is press-fitted into shaft connecting bearing 3a go up and water pump body 2a in, impeller 5a be press-fitted into shaft connecting bearing 3a spool on.
Wherein, belt pulley is two different parts with axle, combines by interference fit, guarantee that concentricity needs higher technological requirement, and the processing technology of axle and belt pulley requires all very high.Work efficiency is low, and difficulty of processing is big, and waste of material is serious, and environmental pollution is serious, and overall weight is big, can not satisfy the needs of automotive industry to the lightweight development.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of light-type automobile cooling water pump easy to assembly of processing at the above-mentioned state of the art.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: a kind of light-type automobile cooling water pump, comprise impeller, water pump body, bearing, rotatingshaft and belt pulley, aforesaid impeller is located at the rotatingshaft front end, aforesaid belt pulley is located at the rotatingshaft rearward end, and aforesaid water pump body is located on the rotatingshaft by bearing, and its spy is that described rotatingshaft impact briquetting is in described belt pulley middle part.
Ear end face impact briquetting one cavity of described rotatingshaft.To reduce overall weight.
Described belt pulley forms radiation hole near on the end face of bearing.Make water pump when running up and with the heat that produces, distribute rapidly, improved the bulk life time of water pump greatly.
The front-end face of described belt pulley and rotatingshaft has annular groove, and the end that is connected of described bearing and water pump body is then pressed and is located in the aforesaid annular groove.Compact structure, assembling is quick.
Be arranged with a mechanical seal that is used to intercept impeller and water pump body on the described rotatingshaft.
Compared with prior art, advantage of the present utility model is: belt pulley and rotatingshaft adopt the punching press one, have saved an axle manufacturing procedure, without machining, directly die sinking just can, die cost is low; Speed of production is fast, and mould and die accuracy is controlled easily, and repair rate is little, and the water pump overall weight reduces greatly, meets the light-duty vehicle development trend; The working environment of workers improves greatly, and whole environmental protection and energy saving are fit to produce in enormous quantities.
