[0002] The motor housing is an important component of the motor. It is generally composed of an annular base, a front cover and a rear cover located at both ends of the base in the axial direction, and cooling fins located on the outside of the base. It not only protects the internal components, but also helps to dissipate heat and reduce noise.

[0003] However, the current motor housing and heat dissipation fins are usually integrally formed, and the fins need to be milled out piece by piece on the outside of the housing during processing, resulting in a large amount of raw material consumption; and the heat dissipation of the motor housing mainly relies on the milled fins, which has insufficient heat dissipation capacity and needs to be improved.

[0004] Therefore, it is necessary to invent a split motor housing to solve the above problems. Utility Model Content

[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0032] The utility model provides Figure 1-5 A split motor housing shown includes an inner ring body 1 for accommodating various components of the motor, and an outer ring body 2 sleeved on the inner ring body 1;

[0033] The outer side of the inner ring body 1 is provided with a groove 3, the groove 3 surrounds the outer side of the inner ring body 1, and the left and right ends of the inner ring body 1 are both provided with a limit ring 4.

[0034] A plurality of grooves 5 are formed on the outer side of the outer ring body 2, each of which is penetrated by a fin 6, and each of which is formed into a T shape by a vertical plate 61 and a horizontal plate 62, and the vertical plate 61 is widened toward the horizontal plate 62 at one end away from the horizontal plate 62;

[0035] The outer ring body 2 is provided with an opening 7 between any two fins 6 , and the opening 7 is arranged to penetrate the outer ring body 2 along the axial direction of the outer ring body 2 , so that the groove 3 is in contact with the outside.

[0036] In one embodiment, the groove 3 is arranged in a spiral shape, and both ends extend to the left and right sides of the inner ring body 1 respectively. The spiral design allows the groove 3 to surround the outer side of the inner ring body 1 in the form of a through groove, so that the opening 7 can be connected with the groove 3 no matter where it is opened, so that external cold air can be infused into the groove 3, thereby improving the heat dissipation capacity of the motor housing.

[0037] In one embodiment, external threads 8 are provided on the outer sides of the left and right ends of the inner ring body 1, and internal threads 9 are provided on the inner wall of the limit ring 4. The inner ring body 1 and the limit ring 4 are threadedly connected via the external threads 8 and the internal threads 9. The inner ring body 1 and the outer ring body 2 are arranged to be interference fit. The interference fit allows sufficient friction between the inner ring body 1 and the outer ring body 2 to prevent the inner ring body 1 and the outer ring body 2 from rotating arbitrarily during use. By screwing in the limit rings 4 at both ends, pressure can be further applied to the two ends of the outer ring body 2, so that the outer ring body 2 will not rotate easily during use.

[0038] In one embodiment, the cross-section of each of the horizontal plates 62 is set to be arc-shaped and adapted to the curved surface of the outer ring body 2. A plurality of the grooves 5 are distributed in a circular array on the surface of the outer ring body 2, and each of the grooves 5 is adapted to the fins 6, so that the fins 6 have sufficient friction when inserted into the grooves 5 and will not easily become loose. After being tightened, the limit rings 4 at both ends can further apply pressure to the fins 6 to prevent the fins 6 from shaking.

[0039] In one embodiment, each of the vertical plates 61 has a plurality of clearance grooves 10 on both sides, and the clearance grooves 10 on each of the vertical plates 61 are evenly spaced from top to bottom, increasing the contact area between the fins 6 and the external environment, thereby further improving the heat dissipation capacity of the motor housing.

[0040] The specific implementation method is as follows: when the utility model is used, the staff screws the upper limit ring 4 on the right end of the inner ring body 1, and then fixes the inner ring body 1 to the right end cover of the motor. The fixing method can be welding, screw fixing, bearing clamping or stopper matching, and then the outer ring body 2 is sleeved on the outer side of the inner ring body 1, and the fins 6 are inserted into each groove 3 in turn, and then the upper limit plate is screwed on the left end of the inner ring body 1, and the left end of the inner ring body 1 is fixed to the left end cover of the motor, and the assembly of the motor housing is completed, thereby meeting the use of the motor;

[0041] Specifically, the motor housing adopts the method of sleeve-mounting the outer ring body 2 on the outer side of the inner ring body 1, so that the originally integrally formed housing becomes a split type, and then a spiral groove 3 is left on the outer side of the inner ring body 1 to allow the heat generated when the motor is working to flow out quickly, and the opening 7 on the outer ring body 2 allows the groove 3 to directly contact the external environment, so that the cold air of the external environment can surround between the inner ring body 1 and the outer ring body 2 along the groove 3, thereby cooling the inner ring body 1 and the outer ring body 2, and at the same time, the heat between the inner ring body 1 and the outer ring body 2 can be quickly input through the groove 3 and discharged from the opening 7, thereby improving the heat dissipation capacity of the motor housing, and the heat dissipation effect is good;

[0042] At the same time, since the fins 6 are inserted into the grooves 5 by sliding, that is, the fins 6 and the outer ring body 2 are also split designs, the outer ring body 2 and the fins 6 can be produced separately, reducing processing loss, and the staff can not insert the fins 6 into the individual grooves 3 according to the use requirements, so that the grooves 3 themselves will directly improve the heat dissipation effect of the outer ring body 2 due to the increase in the contact area between the outer ring body 2 and the outside, thereby reducing the use of the fins 6, saving energy, and avoiding the waste of raw materials;

[0043] This embodiment specifically solves the problem that in the prior art, the motor housing and the heat dissipation fins 6 are usually formed as an integral unit, and the fins 6 need to be milled out piece by piece on the outside of the housing during processing, resulting in a large amount of raw material consumption; and the heat dissipation of the motor housing mainly relies on the milled fins 6, which has insufficient heat dissipation capacity and needs to be improved.

[0044] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
