Embodiment 1
The present embodiment 1 provides a kind of motor.Fig. 1 is the schematic diagram of the motor of the present embodiment.Fig. 2 is the motor of the present embodiment
Casing schematic diagram.
As shown in Figure 1, motor 10 has axis 11, casing 12 and bearing 13.Wherein, axis 11 can be using central axis O in
The heart rotates；Casing 12 has canister portion 121 and flange part 122 centered on central axis O, and canister portion 121, which has, to be axially extended
Inner peripheral surface 121a and outer circumferential surface 121b, end of the flange part 122 from canister portion 121 by the side of paraxial 11 output shaft end 11o
Portion is radially oriented outside extension；Bearing 13 is held in the inner peripheral surface 121a of canister portion 121, and axis 11 is supported as that can rotate.
As shown in Figs. 1-2, the first clamping part 1211 is provided with canister portion 121, the first clamping part 1211 is located at canister portion 121
The close axis input shaft end 11i side, the first clamping part 1211 is subject to from the outer circumferential surface 121b of canister portion 121 in
The pressing in the direction of side face 121a and inner peripheral surface 121a keep bearing 13.
It is corresponding with the first clamping part 1211 relative to the other parts of the inner peripheral surface of canister portion 121 in said motor 10
The inner peripheral surface of canister portion is in the state for being radially oriented inner side pressing, and internal diameter diminishes, can by by bearing be pressed into the part come
Keep bearing.Bearing 13 is kept due to making the first clamping part 1211 depressed, therefore, there is no need to the inner peripheral surface in casing 12
121a sets step, you can realizes the interference fit between casing 12 and bearing 13.
Also, by said motor 10, even in by punch process, and the canister portion of casing that is formed, there are larger ruler
Very little deviation, due to can accurately process the internal diameter size of canister portion 121 by the pressing in subsequent handling, can incite somebody to action
Bearing 13 is held in the inner peripheral surface of canister portion 121.
In the present embodiment, the first clamping part 1211 can be configured to one or more in the circumferential.When being configured to one,
First clamping part 1211 can continuously configure on complete cycle, thus, bearing 13 is being pressed into and is being fixed on the first clamping part 1211
In the case of, it can make to be scattered in complete cycle to the stress of bearing 13.When being configured to multiple, multiple first clamping parts 1211 can be in week
Equally spaced configure upwards, thus, it is possible to be uniformly dispersed the stress to bearing 13.6 the first clamping parts are shown in Fig. 2

In the present embodiment, as shown in Figs. 1-2, the second clamping part 1212, the second folder are can be configured with canister portion 121
Hold the side that portion 1212 is located at the output shaft end 11o for leaning on paraxial 11 of canister portion 121, i.e., side (Fig. 1 identical with flange part 122
In downside), the second clamping part 1212 be subject to the pressing from the outer circumferential surface 121b of canister portion 121 towards the direction of inner peripheral surface 121a and
13 are held in inner peripheral surface holding shaft.Thus, by first, second clamping part 1211,1212 of canister portion 121, a pair of of axis can be fixed
Hold 13.
Second clamping part 1212 can also be configured to one or more in the circumferential.When being configured to one, the second clamping part
1212 can continuously configure on complete cycle, thus, can in the case where being pressed into bearing 13 and being fixed on the second clamping part 1212
Make to be scattered in complete cycle to the stress of bearing 13.When being configured to multiple, multiple second clamping parts 1212 can in the circumferential at equal intervals
Ground configures, thus, it is possible to be uniformly dispersed the stress to bearing 13.6 the second clamping parts 1212 are shown in Fig. 2 in the circumferential
A kind of embodiment equally spaced configured.
The quantity of second clamping part 1212 and the first clamping part 1211 can be identical or different, and Fig. 2 shows the second clamping
A kind of embodiment identical with the quantity of the first clamping part 1211 of portion 1212.In addition, the second clamping part 1212 and the first clamping
Portion 1211 is configured in circumferential identical or different position.
Fig. 3 is the partial schematic diagram of an embodiment of the motor of the present embodiment.
In the present embodiment, as shown in figure 3, canister portion 121 can have path canister portion 121m and major diameter canister portion 121n, its
In, the diameter dimension of major diameter canister portion 121n is bigger than the diameter dimension of path canister portion 121m, and the first clamping part 1211 is located at path cylinder
Portion 121m, the second clamping part 1212 are located at major diameter canister portion 121n, and path canister portion 121m is located at the input for leaning on paraxial 11 of canister portion 121
The side of shaft end 11i, major diameter canister portion 121n are located at the side of the output shaft end 11o for leaning on paraxial 11 of canister portion 121, can make at this time
Be held in the second clamping part 1212 bearing 13n ratios be held in the first clamping part 1211 bearing 13m it is big.Thus, by defeated
Go out the larger bearing (for input shaft side) of shaft end side configuration diameter dimension, can bear to put on the negative of output shaft side
Lotus.
In the present embodiment, as shown in Figure 1, motor 10 can also have rotor portions 14 and stator department 15, rotor portions 14 surround
Axis 11 is arranged at the radial outside of axis 11, and rotor portions 14 may connect to the input shaft end 11i of axis 11, and rotor portions 14 have magnet
141, stator department 15 is arranged at the radial outside of rotor portions 14 around rotor portions 14, is fixed on the outer circumferential surface 121b of canister portion 121, and
Diametrically it is oppositely arranged with magnet 141 across gap.Thus, the motor 10 of outer-rotor type can be formed.Also, by by stator
Casing 12 is fixed in portion 15, for using miscellaneous part come the situation in fixed stator portion, can manufacture horse at low cost
Reach.
In the present embodiment, fixed as shown in Fig. 2, multiple stators can be configured with the outer circumferential surface 121b of canister portion 121
Portion 1213, multiple stator fixed parts 1213 are radially oriented protruding outside, and are arranged at intervals in the circumferential, stator department 15 passes through
Stator fixed part 1213 is fixed on the outer circumferential surface 121b of canister portion 121.Thus, can when stator department 15 is fixed on casing 12
The press-in stress of stator department 15 is absorbed by stator fixed part 1213, is deformed so as to suppress casing 12.
In the present embodiment, when being configured with multiple first clamping parts 1211 in the circumferential, the first clamping part 1211 and fixed
Sub- fixed part 1213 is configured in circumferential identical or different position.
As shown in Fig. 2, the first clamping part 1211 and stator fixed part 1213 are configured at circumferential different position, so match somebody with somebody
When putting, can suppress the first clamping part 1211 should with the press-in stress of bearing 13 and the press-in of stator fixed part 1213 and stator 15
Power interferes with each other, and is deformed so as to suppress casing 12.
Motor through this embodiment, it is not necessary to step is set in the inner wall of casing, you can realize casing and casing internal
Part, such as the interference fit between bearing.
