Embodiments of the present application will be described below with reference to the drawings.

Embodiments of the first aspect

Embodiments of a first aspect of the present application provide a motor. Fig. 1 is a schematic axial sectional view of a motor according to an embodiment of the first aspect of the present application.

As shown in fig. 1, the motor 10 includes a bearing 11 and a bearing accommodating portion 12 for accommodating the bearing 11, and the bearing accommodating portion 12 may be a separate member for accommodating the bearing 11, or may also serve as a bearing accommodating member by forming a space for accommodating the bearing 11 in another member of the motor, which is not limited in this application. Further, the motor 10 further includes a bearing retainer 13, and the bearing retainer 13 is disposed in the bearing housing portion 12 to fix the bearing 11.

In the embodiment of the present invention, as shown in fig. 1, the bearing retainer 13 includes a bearing contact portion 131 and an engagement portion 132, the bearing contact portion 131 contacts the outer periphery of the bearing 11 to apply an axial pressure and a radial pressure to the bearing 11, one end of the engagement portion 132 is connected to the bearing contact portion 131, and the other end of the engagement portion 132 is engaged with the groove 122 formed in the wall portion 121 of the bearing housing portion 12.

As is apparent from the above embodiment, the axial and radial fixing of the bearing 11 can be achieved by one component, i.e., the bearing retainer 13, and the bearing retainer 13 can be reliably retained by engaging the engaging portion 132 with the groove 122, so that the number of required components is small, the assembly and disassembly are easy, and the cost can be reduced.

In the embodiment of the present application, the motor may be of various types, and further, the motor may include other components, such as a rotating shaft, a stator, a rotor, and the like, in addition to the bearing 11, the bearing housing 12, and the bearing pressing ring 13, as referred to in the related art.

In the embodiment of the present application, the bearing abutting portion 131 of the bearing retainer 13 may have various shapes, and the bearing abutting portion 131 may abut on different positions of the outer periphery of the bearing 11, which is not limited in the present application, and only the requirement that the bearing abutting portion 131 abuts on the outer periphery of the bearing 11 to apply axial pressure and radial pressure to the bearing 11 is satisfied, and the following examples will be described, and three of the bearing 11, the bearing accommodating portion 12, and the bearing retainer 13 will be described as a bearing assembly.

Fig. 2 is a schematic view of a bearing assembly including a bearing 11, a bearing receiving portion 12, and a bearing retainer 13 according to an embodiment of the first aspect of the present application, and fig. 3 is another schematic view of the bearing assembly shown in fig. 2, showing components of the bearing assembly in an unassembled state.

As shown in fig. 2 and 3, in one or more embodiments, the bearing abutment 131-1 includes an axial abutment 1311 supported at least in part at one axial end of the bearing 11 and a radial abutment 1312 supported at least in part at the outer radial periphery 111 of the bearing 11, the axial abutment 1311 and the radial abutment 1312 being integrally formed. Accordingly, the axial abutting portion 1311 and the radial abutting portion 1312 are brought into contact with at least a part of one axial end and at least a part of the radial outer periphery of the bearing 11, respectively, whereby the axial force and the radial force can be applied to the bearing 11 more reliably, the bearing 11 can be fixed more reliably, and the axial abutting portion 1311 and the radial abutting portion 1312 are integrally molded, whereby the bearing retainer 13 can be manufactured easily.

For example, as shown in fig. 2 and 3, in one or more embodiments, the axial abutment portion 1311 extends radially inward from one axial end (O end) of the radial abutment portion 1312, and one axial end (O end) of the radial abutment portion 1312 extends axially from the axial abutment portion 1311 to the other axial end (O' end). That is, the bearing abutment 131-1 may include an axial abutment portion 1311 and a radial abutment portion 1312, the axial abutment portion 1311 extending in the radial direction, the radial abutment portion 1312 extending in the axial direction, and one end portion (radially outward) of the axial abutment portion 1311 and one end portion (axially O-end) of the radial abutment portion 1312 being connected.

In the embodiment of the present invention, as shown in fig. 2 and 3, the outer side of the portion where the axial abutting portion 1311 and the radial abutting portion 1312 are connected may be a curved surface, and thus, when the bearing abutting portion 131-1 abuts against the outer periphery of the bearing 11 and receives the reaction force of the bearing 11, the reaction force can be reliably absorbed depending on the characteristics and structural features of the member, and the bearing can be fixed while preventing the bearing from being subjected to undesirable vibration and impact.

Fig. 4 is another schematic view of a bearing assembly including a bearing 11, a bearing receiving portion 12, and a bearing retainer 13 according to an embodiment of the first aspect of the present application, and fig. 5 is another schematic view of the bearing assembly shown in fig. 4, showing components of the bearing assembly in an unassembled state.

As shown in fig. 4 and 5, in one or more embodiments, the bearing abutment 131-2 includes an axial abutment portion 1311 and a radial abutment portion 1312, the axial abutment portion 1311 extending from one axial end (O end) of the radial abutment portion 1313 toward the radially inner side, and one axial end (O end) of the radial abutment portion 1312 extending obliquely from the axial abutment portion 1311 toward the other axial end (O' end) and the radially outer side. Thus, when the bearing 11 is reliably abutted by the axial abutment portion 1311 and the radial abutment portion 1312, the bearing retainer 13 is simpler in structure and easier to manufacture, but is not limited thereto.

Fig. 6 is a further schematic view of a bearing assembly comprising a bearing 11, a bearing receiving portion 12 and a bearing retainer 13 according to an embodiment of the first aspect of the present application, and fig. 7 is another schematic view of the bearing assembly of fig. 6, showing the components of the bearing assembly in an unassembled state.

As shown in fig. 6 and 7, the bearing abutment portion 131-3 may extend obliquely toward the radial outside from one axial end (O end) to the other axial end (O' end), and the rim 112 of the bearing 11 abuts against the bearing abutment portion 131-3. That is, the bearing contact portion 131-3 is inclined, and the inclined bearing contact portion 131-3 comes into contact with the rim 112 of the bearing 11 to apply axial pressure and radial pressure to the bearing 11, thereby fixing the bearing 11. Therefore, the bearing pressing ring is simple in structure and easy to manufacture.

In the above embodiment, the bearing 11 may have a ring shape, and the rim 112 of the bearing is a portion where the bottom surface 113 at one end in the axial direction and the outer peripheral surface 111 are connected. In the case where the bearing abutting portion 131-3 is inclined, the portion of the rim 112 of the bearing 11 in contact with the bearing abutting portion 131-3 may have a shape fitting each other, for example, the rim 112 of the bearing 11 may have an inclined surface, and the inclination of the inclined surface may be the same as the inclination of the bearing abutting portion 131-3, but is not limited thereto.

For example, the bearing abutting portion may be provided with a recess, and the rim of the bearing is engaged with the recess, whereby the bearing abutting portion can support the bearing more reliably.

As shown in fig. 1 to 7, in one or more embodiments, the wall portion 121 of the bearing housing portion 12 is provided with a groove 122, and one end of the engaging portion 132 facing the radial direction outer side is engaged in the groove 122, whereby the bearing retainer 13 can be reliably retained.

In the present embodiment, the engaging portion 132 may have various shapes, which is not limited in the present embodiment, for example, as shown in fig. 2 and 3, the engaging portion 132 may include an inclined portion 1321 and a flat plate portion 1322, one end of the inclined portion 1321 is connected to the bearing abutting portion 131-1, the other end of the inclined portion 1321 is connected to the flat plate portion 1322, and the flat plate portion 1322 is at least partially engaged with the groove 122; but is not limited thereto.

For example, as shown in fig. 4 to 7, the engaging portion 132 may be an inclined portion extending toward the axial direction O end and radially outward, one end of the inclined portion is connected to the bearing contact portions 131-2 and 131-3, and the other end of the inclined portion is engaged with the groove 122, and it should be noted that the shape of the engaging portion 132 is merely illustrated above, but the engaging portion 132 may have other shapes.

In the embodiment of the present application, the shape of the groove 122 may be various, and the present application is not limited thereto, for example, as shown in fig. 3, 5 and 7, the groove 122 may be formed by being recessed from the inner circumferential wall of the bearing housing portion 12 toward the radial outside in a direction parallel to the radial direction, but is not limited thereto.

For example, FIG. 8 is yet another schematic view of a bearing assembly of an embodiment of the first aspect of the present application; FIG. 9 is another schematic view of the bearing assembly shown in FIG. 8.

As shown in fig. 8 and 9, in one or more embodiments, the groove 122 may be formed to be inclined and recessed toward the radial outside in a direction at a predetermined angle from the radial direction from the inner circumferential wall of the bearing housing portion 12, for example, the inclination angle of the groove 122 may be the same as that of the inclined portion as the engaging portion 132 in the embodiment shown in fig. 4 to 7, whereby it is possible to make the engaging portion 132 be engaged with the groove 122 more stably.

It should be noted that the above is merely an example of the shape of the groove 122, but the groove 122 may have other shapes, and the engagement portion 132 may be engaged with the groove 122 to reliably limit the bearing retainer 13.

In one or more embodiments, as shown in fig. 2 and 3, the groove 122 of the wall portion 121 of the bearing housing portion 12 is located at a position of the wall portion 121 of the bearing housing portion 12 opposite to the axial center of the bearing 11. This facilitates insertion of the bearing retainer, and the bearing retainer 13 can be reliably hooked by the engagement between the engagement portion 132 and the groove 122. However, the present application is not limited to this, and the position of the groove 122 in the axial direction of the wall portion 121 of the bearing housing portion 12 may be other positions, for example, as shown in fig. 4 to 7, the groove 122 may be provided in the wall portion 121 near the axial O end, or the groove 122 may be provided in the wall portion 121 near the axial O' end.

In one or more embodiments, as shown in fig. 3, 5, 7, and 9, the bearing retainer 13 is provided with a plurality of engaging portions 132 at equal intervals in the circumferential direction. This facilitates press-fitting of the bearing retainer 13 during assembly. However, the present invention is not limited to this, and for example, one engaging portion 132 may be provided over the entire circumference of the bearing retainer 13, and in the case where a plurality of engaging portions 132 are provided in the circumferential direction of the bearing retainer 13, the plurality of engaging portions 132 may be provided at unequal intervals in the circumferential direction of the bearing retainer 12.

According to the embodiment of the present application, the axial and radial fixing of the bearing 11 can be achieved by one component of the bearing retainer ring 13, and the bearing retainer ring 13 can be reliably restrained by the engagement of the engaging portion 132 with the groove 122, so that the number of required components is small, the assembly and disassembly are easy, and the cost can be saved.
