Technical field
The present invention relates to technical field of motors, particularly a kind of stainless steel motor housing structure.
Background technology
The shell of motor selects the conducts such as cast iron, aluminium alloy, stainless steel to make material according to use occasion is unusual.Stainless steel motor is applied in the industries such as food, medicine equipment, chemical industry widely with its outstanding corrosion resistance.
The shell of traditional stainless steel motor is simple stainless steel thin-wall tubular structure, composition graphs 1, the stator 1 of stainless steel motor is formed by multiple silicon steel plate stacking, the stator 1 be formed by stacking conforms to stainless steel motor housing 2 inwall, for realizing the stator 1 of stainless steel motor and the fixing of shell 2, consider that motor housing 2 wall thickness is excessively thin, general meeting outside wall surface on offer mounting groove 3, the flute length direction of described mounting groove 3 is arranged along the length direction of stator 1, stator imports after in motor housing 2, at the openend of the front and back end of shell 2, front and rear cover is set, the bolt hole that magnitude setting is corresponding respectively on front and rear cover, screw rod is installed to be penetrated by the rear end end cap of shell 2 and by mounting groove 3 until reach the front end of end cap, utilize nut to be screwed by bolt to tighten up, thus realize the fastening of stator 1 and motor housing 2, installation screw rod radial dimension wherein conforms to the groove width of mounting groove 3, that installs that screw rod just achieves stator 1 is spacing, prevent the pivot offset of stator 1.But above-mentioned stainless steel motor weak point is: 1, the external diameter of stator comparatively large (internal diameter conforms to the size of rotor and is of a size of definite value), makes the high expensive of material; 2, stator is offered the mounting groove passed for fastening screw, the zooming performance of motor can be affected; 3, the tightness due to stator outer wall and motor case inwall matched in clearance or combination is inadequate, and motor is in the process of work, and the heat that stator produces can not distribute timely and effectively, and the radiating effect of motor itself is poor.
Summary of the invention
The object of the invention is to: a kind of stainless steel motor housing structure is provided, the production cost of the reality of stainless steel motor can be reduced.
For realizing above object, the technical solution used in the present invention is: a kind of stainless steel motor housing structure, comprises stainless steel casing, and be provided with the lining that heat-conducting is made in described shell, stator is fixedly installed in lining.
Compared with prior art, there is following technique effect in the present invention: the size constancy of stainless steel casing own, a lining is assembled in portion in the enclosure, the stator of motor is squeezed in lining, the stator assembled and lining are squeezed in stainless steel casing, mounting groove or hole can be offered on lining, utilize and realize fixing of stator and motor housing through the screw rod of lining, thus realize the fixing of whole motor, this motor casing structure can avoid fluting or hole on stator, decrease the materials'use amount of stator inactive area, reduce actual motor manufacturing cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of stainless steel motor housing structure of the prior art;
Fig. 2 is the front view of the stainless steel motor housing structure in the present invention;
Fig. 3 is the end view of stainless steel motor housing structure in the present invention.
Embodiment
By reference to the accompanying drawings, the present invention is further described:
A kind of stainless steel motor housing structure, comprise stainless steel casing 10, be provided with lining 20 in described shell 10, stator 30 is fixedly installed in lining 20.
The basis of original casing 10 arranges a lining 20, is squeezed in lining 20 by the stator 30 of motor, realize the fixing of stator 30 and lining 20, for for installing groove that screw rod passes or hole can be opened in lining 20, what realize stator 30 is fixing.The groove that said structure can avoid installation screw rod to pass on the one hand or hole are opened on stator 30, and then avoid the interference to stator 30 zooming performance; Lining 20 structure added on the other hand can reduce the use amount of the actual inactive area of stator 30, and then reduces the materials'use cost of motor stator 30.
As the present invention's preferably scheme, described lining 20 is aluminum alloy materials, lining 20 structure utilizing Aluminum alloy tensile part to make, the heat dispersion of motor can be improved, lining 20 is provided with the groove or hole that pass for screw rod, described groove or hole lining 20 length direction are arranged, and the groove passed for supplying installation screw rod or hole are directly arranged along the length of lining 20, can will realize the fixing of stator 30 and shell 10, and then realize the fixing of whole stainless steel motor.
As preferred version of the present invention, described lining 20 outward flange is provided with mounting groove 21, described mounting groove 21 flute length direction is arranged along the axial length direction of lining 20, this mounting groove 21 passes to realize fixing stator 30 for installing screw rod, and offer at the outward flange of lining 20, processing technology is simple, preferably, the groove interface of mounting groove 21 is U-shaped or semicircle, and the groove width of mounting groove 21 is coincide with the radius installing screw rod, and to make to install, that screw rod realizes lining 20 and stator is fixing.
For realizing the installation of stator 20 and effectively dispelling the heat, described stator 30 forms interference fit with lining 20, the axial length of described lining 20 is greater than the axial length of stator 30, the distance of both ends of the surface distance adjacent stators 30 both ends of the surface of lining 20 is equal, lining 20 is set in outer and the two interference fit of stator 30, realize effectively fixing stator 30 on the one hand, the outer wall of stator 30 can realize the tight laminating with lining 20 inwall on the other hand, the stator 30 that size own diminishes, its outline area diminishes thereupon, stator 30 increases with the area of the contact of lining 20, therefore motor is in the process of work, the heat that stator 30 produces can be distributed by lining 20 fast, the length of the length stator 30 of lining 20 is arranged, significantly can increase the effect of heat radiation, preferably, length 5 ~ the 20mm longer than the length of stator 30 of lining 20.
As preferred version of the present invention, described shell 10 and lining 20 are provided with the screwed hole running through the two, the hole length direction of described screwed hole is vertical with the axial direction of lining 20, shell 10 is provided with spline bolt 40, described spline bolt 40 is through the screwed hole on shell 10 and lining 20 and end is resisted against in groove that the outer wall of stator 30 is supposed, in the screwed hole of shell 10 and lining 20, spline bolt 40 is set, achieve shell 10 on the one hand to fix with the installation of lining 20, on the other hand the end of spline bolt 40 is resisted against in groove that the outer wall of stator 30 is offered, what furthermore achieved that stator 30 is locked, stator 30 is avoided to occur rotational displacement phenomenon.
In the process that the production of reality is assembled, after stator 30 and lining 20 are assembled with shell 10, outer wall along shell 10 is drilled with installing hole, this installing hole be drilled with always put stator 30 outer wall on, after installing hole is drilled with, carry out tapping operation, shell 10 is attacked with the installing hole on lining 20 and establishes in threaded mounting hole, attack after establishing, by spline bolt 40 through the screwed hole on shell 10 and lining 20 and end be resisted against in the groove of the outer wall of stator 30.
