The utility model proposes a kind of motors with the assembling structure of tooth case.

Fig. 1 to Fig. 3 is please referred to, in an embodiment of the utility model, which includes phase with the assembling structure 100 of tooth case The motor 1 and tooth case 3 of connection, motor 1 include the end cap 11 being connected with tooth case 3, motor shaft (not shown) insertion end of motor 1 Lid 11, end cap 11 be equipped with wound motor axis setting bearing wall 15, bearing wall 15 close to motor shaft inner surface be sheathed on Bearing 17 on motor shaft abuts against；Tooth case 3 includes the seat back 31 being connected with end cap 11 and the positioning ring on seat back 31 33, positioning ring 33 is sheathed on the outside of bearing wall 15.

The outside of bearing wall 15 is sheathed on by positioning ring 33, so that the positioning of tooth case 3 and motor 1 is realized, in existing electricity In the structure of machine and tooth case, it is only necessary to which increasing positioning ring 33 can cooperate with bearing wall 15 original on motor 1, reequip at low cost； The size of positioning ring 33 is bigger compared to locating pin, requires the accuracy of manufacture relatively low；Positioning ring 33 is ring structure, is compared In multiple locating pins are inserted into multiple location holes, a positioning ring 33 is sheathed on bearing wall 15, when assembly is easier to be inserted into.

Please refer to Fig. 2 and Fig. 3, one of them of end cap 11 and seat back 31 are equipped with stop hole 111, another is equipped with and stop The stop column 311 that hole 111 matches.In the present embodiment, stop hole 111 is set on the end cap, and the stop column 311 is set to On the seat back 31.Since positioning ring 33 is circle, tooth case 3 and motor 1 are relatively rotated, by the way that stop hole is arranged 111 and stop column 311, prevent tooth case 3 and motor 1 are from relatively rotating.Due to 111 He of stop hole in the utility model Stop column 311 relatively rotates for preventing end cap 11 and seat from carrying on the back 31, compared to the prior art in location hole used for positioning And positioning column, required precision are low.In the present embodiment, the difference maximum of stop hole 111 and stop column 311 can achieve 0.5 ㎜.Only Dynamic hole 111 is opened in abutting part 113, and when being conducive to installation, observation stop column 311 and stop hole 111 are positioned.

Referring to Fig. 2, end cap 11 includes with 31 abutting part 113 that abuts of seat back and from abutting part 113 to separate 3 side of tooth case To the connection wall 115 of extension, and the bottom wall (not indicating) of connection connection wall 115 and bearing wall 15, connection wall 115, bottom wall and Bearing wall 15 surrounds the locating slot 117 of receiving positioning ring 33.By the way that locating slot 117 is arranged, so that between end cap 11 and seat back 31 Gap it is smaller.

End cap 11 and seat back 31 are equipped with bolt hole 119, and the bolt hole 119 opened up on end cap 11 is set to abutting part 113 simultaneously It is uniformly arranged around locating slot 117.Specifically, using on the bolt hole 119 and seat back 31 on screw bolt passes end cap 11 Bolt hole 119, so that seat back 31 and end cap 11 are fastenedly connected.Bolt hole 119 is uniformly arranged, and is conducive to end cap 11 and seat back 31 connects The stability connect.Multiple heat release holes 118 are offered on abutting part 113, heat release hole 118 is uniformly arranged around locating slot 117.Heat dissipation Hole 118 is used to dissipate the heat that the movement of motor 1 generates.

Referring to Fig. 3, seat back 31 includes the protrusion for protruding setting on the outside of main part 313 and multiple main bodies 313 315, positioning ring 33 is connected with main part 313, and stop column 311 or stop hole 111 are set to protrusion 315.It is protruded by setting On the one hand portion 315 is conducive to installation and fixes, on the other hand reduce the contact area of seat back 31 with end cap 11, be conducive to motor 1 Heat dissipation.

Escape groove 319, the escape groove 319 and 118 phase of heat release hole are formed between the two adjacent protrusions 315 It is corresponding, it is blocked so that heat release hole 118 will not be carried on the back 31 by seat, is conducive to the heat dissipation of motor 1, protrusion 315 and escape groove 319 are set In turn ensure that seat back 31 there are enough contacts area with end cap 11.

Multiple holes 317 are offered on main part 313, hole 317 is set between positioning ring 33 and protrusion 315.The reality Setting hole 317 in example is applied, so that the surface area that abutting part 113 and main part 313 directly contact is reduced, is conducive to motor 1 and dissipates Heat.

The utility model additionally provides a kind of fan (not shown), including flabellum and motor as the aforementioned with the assembly of tooth case Structure 100, flabellum are connected with one end of motor shaft.Since this motor uses above-mentioned all implementations with the assembling structure of tooth case Whole technical solutions of example, therefore at least all beneficial effects brought by the technical solution with above-described embodiment, herein not It repeats one by one again.

The above is only the preferred embodiment of the present invention, and therefore it does not limit the scope of the patent of the utility model, It is all under the design of the utility model, equivalent structure transformation made based on the specification and figures of the utility model, or Directly/be used in other related technical areas indirectly and be included in the scope of patent protection of the utility model.
