Detailed description of the invention

Of the present utility model embodiment is described below in detail, and the example of described embodiment is shown in the drawings.Below by The embodiment being described with reference to the drawings is exemplary, it is intended to be used for explaining this utility model, and it is not intended that new to this practicality The restriction of type.

1 specifically describe the compressor stator 711 according to this utility model embodiment below in conjunction with the accompanying drawings.

Compressor stator 711 according to this utility model embodiment includes that body 7111, the middle part of body 7111 are provided with Through hole 7111a, the inner ring of body 7111 be provided with multiple stator tooth 7111b arranged spaced apart, adjacent two stator tooth 7111b it Between limit and through hole 7111a conducting stator slot 7111c, the internal diameter of body 7111 is D1, and external diameter is D2,0.490≤D1/D2 ≤ 0.505, the distance between the both sides outer contour of each stator tooth 7111b is L, 2.65mm≤L≤3.15mm.

In other words, the body 7111 of this compressor stator 711 is mainly made up of multiple stator lamination stackings, wherein, often The middle part of individual stator punching is provided with through hole 7111a, and the shape of the body 7111 of multiple stator punchings composition substantially circularizes, at this Spaced apart multiple stator tooth 7111b, interval shape adjacent two stator tooth 7111bs between are distributed on the inner ring of body 7111 Become stator slot 7111c.

Wherein, two be oppositely arranged and the line of centres through body 7111 center stator tooth 7111b top away from From being formed as the internal diameter D1 of body 7111, the outer diameter D 2 of body 7111, body 7111 internal diameter with the proportion of external diameter is: 0.490≤D1/D2≤0.505。

Further, at body 7111 in the radial direction, distance L between the both sides contour line of each stator tooth 7111b, In the most adjacent two stator slot 7111c, the spacing distance between the sidewall of opposing setting is L, and L is in the range of 2.65mm≤L ≤ 3.15mm, such as, distance L between the both sides contour line of each stator tooth 7111b can be 2.65mm, 3mm or 3.15mm, specifically, can need to select according to the radial dimension of body 7111 and design suitably sized.

Thus, according to the compressor stator 711 of this utility model embodiment, by setting body 7111 internal diameter, external diameter Proportion and the both sides contour line of each stator tooth 7111b between distance range, the size of stator 711 is carried out excellent Change, between body 7111 internal diameter, external diameter and the both sides contour line of stator tooth 7111b that rationally can select in given area Distance value, sets an appropriate number of stator tooth 7111b, it is possible to reduce the consumption of copper cash, alleviates the weight of copper cash, thus improve electricity The work efficiency of machine 7 and performance, and then improve the performance of compressor 100.This compressor simple in construction of stator 711, material Cost is relatively low, beneficially the cost performance of lifting motor 7.

Further, the angle between the centrage of adjacent two stator slot 7111c is Ф, 12.5 °≤Ф≤17.5 °. Multiple stator slot 7111c, the two of each stator tooth 7111b are limited with reference to Fig. 1, the multiple stator tooth 7111b on body 7111 Distance between side wheel profile is L, and in the most adjacent two stator slot 7111c, the spacing distance between the sidewall of opposing setting is L In the range of: 2.65mm≤L≤3.15mm, and the angle between the centrage of adjacent two stator slot 7111c is Ф, and angle In the range of: 12.5 °≤Ф≤17.5 °, such as, the angle Ф between the centrage of adjacent two stator slot 7111c can be 12.5 °, 15 ° or 17.5 °, thus the optimization for the dimensional parameters of stator 711 provides foundation.

Preferably, the angle Ф between the centrage of adjacent two stator slot 7111c is 15 °.It is to say, according to being given Adjacent two stator slot 7111c between angular range, 12.5 °≤Ф≤17.5 °, in this zone of reasonableness to groove between press from both sides Angular dimensions is optimized, and draws in the case of other parameters are certain, the folder between the centrage of adjacent two stator slot 7111c When angle Ф is 15 °, having reached optimal design, the weight of copper wire used is minimum, and cost used is minimum, and the motor 7 reached is imitated Rate is the highest.

Advantageously, D1/D2=0.497.In other words, the proportion of body 7111 internal diameter and external diameter is 0.490≤D1/ D2≤0.505, does optimization further, it can be deduced that when other parameter constants to the internal diameter of body 7111 and the ratio of external diameter, Body 7111 internal diameter and the ratio of external diameter: during D1/D2=0.497, body 7111 internal diameter, this parameter designing of ratio of external diameter obtain Having arrived optimal design, compared with other ratio values of proportion, the weight of copper wire now used is minimum, and cost used is Low, motor 7 efficiency reached is the highest.

Alternatively, distance L between the both sides outer contour of each stator tooth 7111b is 2.95mm.In like manner, at body 7111 in the radial direction, distance L between the both sides outer contour of each stator tooth 7111b in the range of: 2.65mm≤L≤ 3.15mm, optimizes further to this distance range, can draw each stator tooth 7111b both sides profile in remaining parameter one timing The design optimal value of spacing be 2.95mm, compared with other values of L, the work efficiency of motor 7 now can be made to reach Height, service behaviour is preferable.

In certain specific embodiments of the invention, stator slot 7111c includes stator sulculus 7111d and stator vat 7111e, the bottom land footpath of stator sulculus 7111d is D3, and the bottom land footpath of stator vat 7111e is D4,0.94≤D3/D4≤0.98.

With reference to Fig. 1 it can be seen that limit a stator slot between adjacent two stator tooth 7111b on body 7111 7111c, the stator slot 7111c limited include stator sulculus 7111d and stator vat 7111e, two be oppositely arranged and in Heart line is D3 through the distance from bottom of the stator sulculus 7111d at the center of body 7111, and two are oppositely arranged and the line of centres Distance D4 bottom the stator vat 7111e at the center of body 7111, the ratio range of D3 with D4 is: 0.94≤D3/D4 ≤ 0.98, by limiting the proportion of D3 Yu D4, for optimizing the reference frame that design provides certain.

Specifically, the quantity of stator vat 7111e is 16, and the quantity of stator sulculus 7111d is eight, and every four stators are big Groove 7111e is disposed adjacent formation one group, and each two stator sulculus 7111d is disposed adjacent formation one group, two adjacent groups stator vat One group of stator sulculus 7111d it is provided with between 7111e.

With reference to Fig. 1, ten six stator vat 7111es and eight stator sulculus 7111ds on body 7111 inner ring, are distributed, fixed Sub-vat 7111e and stator sulculus 7111d each point four groups layouts on inner ring, often the quantity of group stator vat 7111e is four, Often the quantity of group stator sulculus 7111d is two, often group stator vat 7111e and often group stator sulculus 7111d interval layout, i.e. One group of stator vat 7111e, i.e. every two adjacent groups stator vat is arranged between the stator sulculus 7111d of every two adjacent groups Arrange one group of stator sulculus 7111d between 7111e, so stator slot 7111c is optimized layout, it is possible to reduce the use of copper cash Amount, thus reduces the weight of copper cash, can lifting motor 7 service behaviour further, it is achieved the maximization of motor 7 efficiency.

Preferably, D3/D4=0.961.In other words, two are oppositely arranged and the line of centres is through the center of body 7111 Stator sulculus 7111d bottom distance D3 and two be oppositely arranged and the line of centres is big through the stator at center of body 7111 Body 7111 center of circle of distance D4 bottom groove 7111e is to distance from bottom and body 7111 center of circle of stator sulculus 7111d to calmly The ratio range of the distance bottom sub-vat 7111e is: 0.94≤D3/D4≤0.98, in the ratio optimization range having been provided that, The optimum ratio obtaining D3/D4 is 0.961, say, that when other parameters are certain, and body 7111 center of circle is to stator sulculus When the distance from bottom of 7111d is body 7111 center of circle to 0.961 times of the distance bottom stator vat 7111e, this parameter designing Reaching optimum, now motor 7 efficiency is the highest, and motor 7 performance is best, and compressor 100 performance have also been obtained optimization further.
