Abstract
The utility model relates to a new-type electric motor for a ceiling fan. A shell and a bearing seat are integral structures with integral stretching molding, and a lower bearing adopts a powder metallurgical oil retaining bearing. The new-type electric motor for a ceiling fan has the advantages of low cost, low noise, and easy processing.
Description
The utility model relates to a kind of ceiling fan motor.
Existing ceiling fan motor, its housing adopts composite construction usually, forms these parts of housing by shell and two part spot welding of bearing pedestal or electric welding together, metal (upper all adopts radial ball bearing, the processing technology complexity, the cost height, and certain mechanicalness noise is arranged.The purpose of this utility model is to improve the shell structure of ceiling fan motor, provides a kind of processing easy, with low cost, superior in quality novel ceiling fan motor.
Main points of the present utility model are integral structures that shell and bearing pedestal adopt the integrally stretching moulding, and bearing pedestal need not welding in addition and turning processing, and concentricity is good.Simultaneously, motor below bearing adopts telescopic sliding bearing (being generally powder metallurgy oil-impregnated bearing), and promptly armature spindle and below bearing are sleeve type activity draw bail, and mechanicalness noise greatly reduces in the time of can making running, and reaches easy-to-disassemble and assemble effect.
Accompanying drawing is the cutaway view of a specific embodiments of ceiling fan motor of the present utility model.
Accompanying drawing has been done concrete description to structure of the present utility model, and 1, armature spindle, 2, upper bearing (metal), 3, go up shell, 4, rotor, 5, stator, 6, lower casing, 7, lower bearing (powder metallurgy oil-impregnated bearing)
Below in conjunction with drawings and Examples the utility model is described further, last shell 3. and lower casing 6. all are monolithic constructions, adopt deep-draw type cold-rolled steel sheet will go up shell 3. and lower casing 6. punch formings in an embodiment, bearing pedestal and shell are all one, need not other welding, turning processing, after upper bearing (metal) 2. and lower bearing 7. be pressed into the bearing pedestal of upper and lower shell, can obtain good concentricity, lower bearing 7. adopts copper base or iron-based powder oiliness bearings usually.The integral installation timing, rotor 4. is pressed and is embedded in the lower casing 6., and stator 5. is fitted on the armature spindle 1., and the weight of rotor 4. is delivered to shell 3. through lower casing 6. and transmits through upper bearing (metal) 2., finally bears total weight by armature spindle 1..Lower bearing 7. does not bear vertical gravity, and during running, the wear extent of armature spindle 1. and lower bearing 7. seldom.Adopt the ceiling fan motor of this kind structure, process easy, easy disassembling, mechanism noise is little, the production efficiency height is that a kind of cost is low, the novel ceiling fan motor that performance is good.
Claims (2)
1, a kind of novel ceiling fan motor is made up of last lower casing, metal (upper, rotor, it is characterized in that shell and bearing pedestal are integral type drawing and forming structure, and its below bearing is telescopic sliding bearing.
2, the described ceiling fan motor of claim 1, its feature are that also the telescopic sliding bearing of its below is a powder metallurgy oil-impregnated bearing.
