The utility model proposes a kind of motor.

In the utility model embodiment, reference picture 3 to Fig. 6, the motor includes：

Ring-type casing 1, there is the first opening (not shown) being oppositely arranged and the second opening (not shown)；

First end cap 2, cover the setting of the first opening；The middle part of first end cap 2 is provided with shaft hole 21；

Second end cap 3, cover the setting of the second opening；The position that the inside middle portion of second end cap 3 corresponds to shaft hole 21 is provided with Support slot 31；And

Rotating shaft 51, adaptation wear shaft hole 21, support slot 31 notch and abut support slot 31 bottom land set；Wherein,

The hole wall of shaft hole 21 and/or the groove sidewall of support slot 31 are arranged with lubrication groove, and lubrication groove internal memory contains lubricant.

It is appreciated that motor also includes field frame assembly 4 annular in shape in ring-type casing 1 and surround by field frame assembly 4 Mouse cage 52, rotating shaft 51 wears the inner chamber of mouse cage 52, and mouse cage 52 and rotating shaft 51 collectively form the rotor assembly 5 of motor；This implementation In example, the hole wall of shaft hole 21 and the groove sidewall of support slot 31 are all arranged with lubrication groove, certainly, in other embodiment, rotating shaft The hole wall in hole 21 is provided with lubrication groove, is still provided with support slot 31 to install the installation chamber of bearing assembly, or support slot 31 Groove sidewall be provided with lubrication groove, be still provided with shaft hole 21 to install the installation chamber of bearing assembly, the design does not make to this Limitation.In addition, in the present embodiment, lubricant is lubricating oil, and certainly, in other embodiment, lubricant is also lubricating grease etc. Product with lubrication.

The hole wall and/or the second end cap 3 that technical solutions of the utility model pass through the shaft hole 21 of the first end cap 2 in motor Support slot 31 groove sidewall set lubrication groove, lubrication groove internal memory contains lubricant, to substitute the bearing of original motor correspondence position Component, so as under the premise of ensureing that rotating shaft 51 rotates smoothly, simplify the installation process of motor, improve the installation effectiveness of motor.

Further, axial direction of the lubrication groove along shaft hole 21 and support slot 31 is set in the shape of a spiral.It is appreciated that so set Put, reduce lubrication groove and the length along the radial direction of rotating shaft 51 for improving effect is had no to lubrication, ensure that lubrication groove can improve The length along the axial direction of rotating shaft 51 of lubricant effect, and each radial position of rotating shaft 51 can also be made uniformly to lubricate.Need to illustrate , the design not limited to this, in other embodiment, lubrication groove is alternatively what is be coaxially disposed with shaft hole 21 and support slot 31 Annular groove.

Further, the notch of lubrication groove is 1mm~3mm along the depth of shaft hole 21 and the radial direction of support slot 31.Can be with Understand, the radial depth of notch is bigger, the structural strength of the connection hole (at the support slot 31 of the second end cap 3) of the first end cap 2 It is poorer；The radial depth of notch is smaller, and the lubricant of lubrication groove interior energy storage is fewer, and during motor long-term use, user adds profit Lubrication prescription is frequent, influences motor working efficiency.

Further, the notch of lubrication groove is 0.5mm~3mm along the axial width of shaft hole 21 and support slot 31.Can To understand, the axial width of notch is bigger, and the structure of the connection hole (at the support slot 31 of the second end cap 3) of the first end cap 2 is strong Degree is poorer；The axial width of notch is smaller, and lubrication groove and effective contact area of rotating shaft 51 are smaller, and lubrication gets over unobvious.

Further, lubrication groove includes the first lubrication groove 211 of the recessed hole wall in shaft hole 21, and recessed in support Second lubrication groove 311 of the groove sidewall of groove 31；First lubrication groove 211 is located at shaft hole 21 away from one end of the second end cap 3 and deviated from The opening inner side of second end cap 3；Second lubrication groove 311 is located at towards one end of the first end cap 2 on the inside of the notch of support slot 31.Can To understand, the first lubrication groove 211 and the second lubrication groove 311 are arranged to obstructed type groove, can effectively avoid lubricant from lubrication groove Interior outflow, prevent the waste of lubricant.

Further, reference picture 4, axial development length of first lubrication groove 211 along shaft hole 21 and support slot 31 are S, S value are 10mm~20mm.It is appreciated that S is excessive, the structural strength of the connection hole of the first end cap 2 is poorer；S is too small, Lubrication groove and effective contact area of rotating shaft 51 are smaller, and lubrication gets over unobvious.

Further, rotating shaft 51 includes the first shaft part 511 and the second shaft part 512 being coaxially disposed, and the first shaft part 511 plugs Support slot 31, the second shaft part 512 wear shaft hole 21, and the radical length of the first shaft part 511 is more than the second shaft part 512；First axle Section 511 and second is by an annular step surface 512a connections between shaft part 512, and shaft hole 21 is towards in the opening of the first end cap 2 Side is provided with adaptation annular step surface 512a annular chamfer 212.It is appreciated that be arranged such, can preferably avoid rotating shaft 51 with Stuck situation occurs between the opening of shaft hole 21, ensures the smoothness that rotating shaft 51 rotates.

Further, reference picture 5, the angle of annular chamfer 212 and horizontal direction are α, α span for 35 °~ 50°.It is appreciated that α is excessive, there are corner angle the periphery of the second shaft part 512 with the junction of shaft hole 21, and the long-term work of rotating shaft 51 can It can be worn, α is too small, the anti-jamming effect unobvious of annular chamfer 212.In the present embodiment, α is 45 °, certainly, in other In embodiment, α is alternatively other numerical value between 35 °~50 °.

Further, the first end cap 2 and the second end cap 3 are made by aluminum process.It is appreciated that cast-aluminum end cover is existing Motor widely use, have the characteristics that technique is simple, Stability Analysis of Structures；In addition, in the present embodiment, ring-type casing 1 is by roll bending work Skill is made, and certainly, the design not limited to this, in other embodiment, ring-type casing 1 can also be made up of other techniques.

The utility model also proposes a kind of air conditioner, and the air conditioner includes motor, and the concrete structure of the motor is with reference to above-mentioned Embodiment, because this air conditioner employs whole technical schemes of above-mentioned all embodiments, therefore at least there is above-described embodiment Technical scheme caused by all beneficial effects, this is no longer going to repeat them.

Preferred embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model, Every equivalent structure under utility model of the present utility model design, made using the utility model specification and accompanying drawing content Conversion, or directly/be used in other related technical areas indirectly and be included in scope of patent protection of the present utility model.
