In the prior art, the selected material of shell of similar motors such as the general fan motor of using always, ventilating fan motor is panel beating steel or cast aluminum alloy material.When using the panel beating steel, because will be applied to the drawing process of metal panel beating, the part product needs just can process through opening multinomial complicated procedures of forming such as material, pull-up, replica, typing, finishing, punching, side cut, tapping, plating.The finished product rate is about 97%.Existing sheet metal component motor housing commonly used exists cost of raw material height, processing technology complexity, processing cost height, and the sheet metal component formed precision is difficult to guarantee, the finished product accuracy consistency is poor, the shortcoming of production cycle length.When adopting cast aluminum alloy material, because of using non-ferrous metal, have the high shortcoming of the cost of raw material, and need through machining operations such as finish-milling, boring, tapping, processing cost is also than higher.
Motor housing generally is made up of two motor cover.And applied bearing is generally oiliness bearing in the motor cover.As shown in Figure 1, oiliness bearing A1 is the spherical shape bearing of powdered metallurgical material among the figure, and the centre is provided with the through hole that cooperates with axle, can store enough lubricants in order to make its inside, this bearing needs bigger oil-containing volume, contain asphalt felt A4 surround oiliness bearing A1 around.In existing oiliness bearing device commonly used, form the bearing chamber cavity with gland A5 and front end housing A2 riveted and fixed.Hold spherical powder metallurgy oil-impregnated bearing A1 in the bearing chamber cavity, pressing metallurgical oiliness bearing A1 sphere as the compression spring A 3 of support shape, and by the elastic reaction of compression spring A 3 oiliness bearing A1 is made axial elasticity and oppress, make its sphere fit tightly the Internal Spherical Surface of housing front end housing A2, thus can be to spherical oiliness bearing A1 location.There is following shortcoming in this structure: positioning accuracy is subjected to the restriction of riveted joint precision between casing front end housing A2 and the gland A5 and two s' machining accuracy, and both riveted joint precision are restricted by operator's technical merit, precision is difficult to guarantee, therefore, its axiality, precision are relatively poor, thereby cause the service behaviour consistency of oiliness bearing in motor poor.
The utility model content
The utility model technical issues that need to address, being the purpose of this utility model, is for a kind of motor cover of tape spool bearing apparatus is provided, and this kind motor cover can reduce manufacturing procedure, reduce production costs, improve with the oiliness bearing setting accuracy and the service behaviour that improves oiliness bearing.
The purpose of this utility model reaches by the following technical solutions:
A kind of motor cover with plastic packaging bearing arrangement is characterized in that: comprise housing, plastic packaging bearing arrangement, the housing middle part is provided with the bearing arrangement mount pad, and described bearing arrangement mount pad and housing are one-body molded, and plastic packaging bearing arrangement is fixed in the bearing arrangement mount pad; The bearing pedestal of bearing arrangement mount pad and plastic packaging bearing arrangement is connected as a single entity.
The technical solution of the utility model can also be taked following measure:
Aforesaid plastic packaging bearing arrangement is made up of plastic base, oiliness bearing; Described plastic base is made of bearing pedestal and lubricating cup, and bearing pedestal and lubricating cup link together; The end face of plastic base is provided with connecting hole, is provided with a chamber that is complementary with the oiliness bearing profile in the plastic base; Described chamber wall is provided with the groove of placing the immersion oil felt, and the immersion oil felt is placed in the described groove; Oiliness bearing places in the described chamber, and the axis hole in described connecting hole and the oiliness bearing is communicated with.
Aforesaid bearing pedestal and bearing arrangement mount pad are connected as a single entity, and one-body molded with housing.
Aforesaid housing is provided with the space, between two spaces support bar is set, and the bearing arrangement mount pad is connected with the support bar support fixation.
Aforesaid housing is made of fire retardant plastic material.
Aforesaid fire retardant plastic material is ABS or PC or PP plastic material.
The utlity model has following outstanding effect:
1, the utility model bearing arrangement mount pad and housing are one-body molded, are to be compared through the structure that forms bearing pedestal after the multinomial manufacturing procedure by sheet metal component with the Bearing Installation seat of prior art, and production technology is simple, saves cost.And the position precision height of integrally moulded bearing arrangement mount pad in shell, homogeneity of product is strong.The position precision height of bearing arrangement mount pad in shell helps improving in the mount pad setting accuracy of oiliness bearing in the plastic packaging shaft device, thereby can improve the service behaviour of oiliness bearing.
2, the utility model bearing arrangement mount pad can be connected as a single entity with the bearing pedestal of plastic packaging bearing arrangement, and can be one-body molded with housing, and bearing pedestal and housing are one-body molded, can improve its axiality.When assembling, the lubricating cup part cooperates with the bearing pedestal at injection-moulded housing place and is one through the ultrasonic welding process fusion, forms the bearing chamber.Oiliness bearing and lubricating oil felt are included in the bearing chamber of sealing, and ball bearing can rotate freely from the dynamic(al) correction axiality, and the high-precision coaxial degree cooperates and the absorbing effect of injected plastics material disappears the rotation dead point of motor, and noise and vibration improve greatly.Lubricating oil does not leak in the bearing chamber of sealing, prolongs electrical machinery life.
3, the utility model is simple in structure, and the pedestal of housing and plastic packaging bearing arrangement all is to be made of fire retardant plastic material.Compared with prior art, production craft step is few, and installation step is also few.After adopting the structure of utility model, the process-cycle of motor housing shortened to 1 day from original 15 days.Rate of finished products brings up to 99.5% from 97%, and the consistency of motor housing improves greatly, and the motor housing material cost descends 20%, and the motor efficiency of assembling improves 30%, and the once mounting qualification rate is brought up to more than 95% from about 85%.
4, the utility model is widely used, and adaptability is strong, can be used as the shell of daily motor.
