In the present embodiment, so that casing 100 can preferably be dispelled the heat, (casing 100 is follow-up assembles, in figure with motor
Do not show that), wherein can be provided with radiating ribs 112 on columnar part 110 surface, this radiating ribs 112 one end extends to end face portion 120
Place, and with protuberance 123, there is predeterminable range, predeterminable range herein refers to, the length of radiating ribs 112 can not extend to convex
Going out portion 123, it is to avoid bearing chamber 123a is directly affected by radiating ribs, equally, this radiating ribs 112 can also be with casing 100 one
Casting, when meander line structure therein at least can also partially remove hot jacket, radiating ribs 112 should to the extruding of protuberance 123
Power.
In the present embodiment, above-mentioned radiating ribs 112 can be multiple, and multiple radiating ribs 112 are along columnar part 110 circumference uniformly
Distribution, the radiating ribs 112 extrusion stress to protuberance 123 time accordingly in order to eliminate hot jacket.
In the present embodiment, it is positioned at the radiating ribs 112 at the first wall 121 and is positioned at the radiating ribs 112 at the second wall 122 even
The place of connecing offers beginning structure 112a, and this beginning structure 112a cross sectional shape can be triangle or arc or other shapes,
This beginning structure 112a can reduce the stress deformation impact on bearing chamber while increasing area of dissipation.
In the present embodiment, at meander line structure, wall thickness can be slightly larger than the first wall 121 wall thickness, such as at the first wall 121 (i.e.
Mild place) casing thickness can be 2.8mm, and the wall thickness at meander line structure can be 3mm, by increasing the table at meander line structure
Area and volume, and then reduce the stress intensity at broken line.
This casing 100 structure carries out force analysis, and with reference to Fig. 3, Fig. 4 and Fig. 5, the radiating ribs 112 of elongation is to bearing chamber
The extruding force of 123a is inside along radial direction, and size is F1.To casing 100 internal stress analysis, contact surface on meander line structure
Place, power F1With the formal distribution of stress σ on cross section, the power balanced with it is F2(F2Do not show that in the drawings), by meander line structure
It is divided into two parts and carries out stress analysis, the i.e. first meander line structure 122a and the second meander line structure 122b, wherein the first meander line structure
Highly L1, the second meander line structure 122b height L2。
At first meander line structure 122a, end face portion 120 stress balance and upper and lower surface area are A, then have:
Owing to the first meander line structure 122a has the deflection at the first inclination angle (α angle shown in figure) so that not straight at one
Stress on line creates moment of flexure, when the first meander line structure 122a is in equilibrium of couples state, and can be by from the second broken line
The moment M of structureBA, this casing 100 is not preferable rigidity casing, and it has certain elastic modelling quantity.
First meander line structure 122a can bend towards downside certain angle under Moment.In like manner analyze the second meander line structure
The stress state of 122b, it has the second inclination angle (β angle shown in figure), has σ3=σ4, due to the existence second of interaction force
Meander line structure 122b is by Moment power M from the first meander line structure 122aAB, wherein MAB=MBA, such second broken line knot
Structure can bend towards upside certain angle.
Owing to the first meander line structure 122a and the second meander line structure 122b bends in opposite directions simultaneously, cause now the first broken line knot
Structure 122a and the second meander line structure 122b whole height diminish, and height reduction provides elongation can to the bearing chamber of expanded by heating
Space, decreases the inside of bearing chamber and is heated extrusion stress.In like manner, after hot jacket terminates, stator module reaches with end face portion 120
Interference fit, at this time, chilled end face portion 120, due to the existence of stator module Yu end face portion 120 matching allowance,
Receiving the effect of tensile stress, in this case, now the first meander line structure 122a and the second meander line structure 122b becomes
Bend dorsad simultaneously, alleviate the tensile elongation amount of end face portion 120.
On the other hand, the application relates to a kind of motor, including the casing 100 described in any of the above-described embodiment.
Each technical characteristic of embodiment described above can combine arbitrarily, for making description succinct, not to above-mentioned reality
The all possible combination of each technical characteristic executed in example is all described, but, as long as the combination of these technical characteristics is not deposited
In contradiction, all it is considered to be the scope that this specification is recorded.
