Flange has been changed to whole inner ring by the product, can be gone out after reduction formed product as far as possible when molding in this way
Existing stress release and rebound, it is more steady when operating motor, reduce noise and reduces temperature rise.
In use, air conditioner motor is mainly by front housing, rotor core and rotor windings, stator core and stator winding, base
The composition such as seat, outlet box, back cabinet, fan and fan housing.
Front housing and back cabinet are the installation foundations of operated motor, stator core, stator coil, rotor permanent magnet poles and
Bearing and axis are all mounted in inside the casing of front and back.
The technique and structural improvement carried out mainly for the motor housing of air conditioner motor, by product on product structure
Flange arrangement improves the molding structure circularized by the mechanism of original big plane abnormal shape, and such design scheme can be effective
Avoid the problem that flange caused product seam allowance internal diameter circularity when trimming becomes larger and seam allowance internal diameter changes, while
The outer rim of flange is subjected to flanging process simultaneously in subsequent shaping, there is flange also simultaneously in flange while making internal diameter shaping
Effect has clasped the direction and reduce corresponding resilience problem that product material flows, so that seam allowance internal diameter, the circle of product
Degree precision reach a higher level, simultaneously as seam allowance internal diameter be carried out again after positioning bearing chamber it is molding because
Seam allowance internal diameter is by being remarkably enhanced seam allowance internal diameter and circularity after structural improvement, so that in bearing chamber and seam allowance
The coaxial accuracy of diameter is also greatly improved.
Casing after remodeling achieved the purpose that reduce lower noise temperature rise in motor assembly test, due to bearing chamber and
The coaxial accuracy of seam allowance internal diameter is improved significantly, so that the stationarity of motor operating also improves.
After the shape of flange changes simultaneously, the installation space of motor is also simplified, and such later period can will set early period
The motor case of most of different flange shapes of meter all realizes standardization uniform type, simplifies design cycle and optimizes product class
Type reduces remodeling for producing line and the time and promotes the production capacity of producing line, enterprise is made to obtain bigger interests income and profit.
