Specific embodiment
The motor according to first preferred embodiment by the present invention is described in detail referring to Fig. 1 and 2.
Fig. 1 shows the phantom of motor 1, and the motor has housing 2, axle 3 and rolling bearing 4, the axis of rolling
Hold with internal ring 5, outer shroud 6 and a large amount of rolling elements 7, only visibly show two in the cross-section in these rolling elements
Rolling element 7.Rolling bearing 4 on the housing bottom 9 of the housing end region 8 for leaning against housing 2 is with outer shroud 6 by means of on housing 2
Entirely around be arranged in parallel first and second be welded to connect 10,11 and be fixed.Thus, the rolling bearing 4 is defined
The floating bearing of motor 1, the outer shroud 6 of the bearing is fixed on housing 2 and the internal ring 5 of the bearing is pivotably supported the axle
3.As an alternative, it is also possible to be provided as the design of fixing bearing, wherein the internal ring 5 is extraly by means of laser
Device is welded on axle 3.
It is described two to be welded to connect 10,11 from the outside 13 of housing 2 radially preferably with laser instrument as seen in Fig. 2
The form being welded to connect applies to weld in other words through housing 2.Here, laser beam is radially focused on from the outside on housing 2, from
And due to the energy of lasers input for applying, construction is welded to connect 10,11 between the outer shroud 6 and housing 2.Replace described two
Individual parallel first and second are welded to connect 10,11, it is also possible in order to fix the outer shroud 6 only arrange one it is single complete
Circular is welded to connect.Additionally, replace one or more entirely around be welded to connect, it is also possible to alternatively arrange one or
What the multiple one or many of person interrupted is welded to connect.Additionally, one or each be welded to connect can also be configured to it is single with
Prespecified angular distance is located remotely from each other the form of the pad of arrangement.
The motor according to the second preferred embodiment by the present invention is described in detail referring to Fig. 3 and 4.Here, identical
The identical of function in other words part with representing with first embodiment identical reference.
As it is seen from figure 3 that, and unlike first embodiment, the third and fourth welding in this second embodiment connects
20,21 are connect vertically in other words in side construction on housing 2.The housing is in this embodiment sleeve 22.Here, passing through
Applying laser energy is in the boundary region of the axial excircle along outer shroud 6 and the inner periphery of housing 2（Fig. 3）Construction institute
State the 3rd and be welded to connect 20.By the way that laser energy to be applied to the boundary area along the excircle of axle 3 and the inner periphery of internal ring 5
Construction the described 4th is welded to connect 21 in domain.In the contrary axial sides of the roll inside bearing 4 of sleeve 22（Referring to Fig. 4）
In an identical manner construction the 5th is welded to connect 23 and in axle 3 and internal ring 5 in the boundary region between outer shroud 6 and sleeve 22
Between boundary region in construction the 6th be welded to connect 24.
20,21,23,24 are welded to connect by the internal ring 5 and outer shroud 6 by means of the three, the four, the 5th and the 6th
It is fixed on sleeve 22, the rolling bearing 4 defines the fixing bearing of motor 1, the fixing bearing can also reliably bear
And larger axial force and impact that support occurs.When axial force is less, it is also possible to alternatively only by welding company
20 and 21 constructions are connect on the side of sleeve 22 or 23 and 24 constructions will be welded to connect is used for fixed rolling in the inside of sleeve 22
Dynamic bearing 4.
As an alternative, can be by axially only welding a bearer ring in other words in side, by the rolling bearing 4
Also serve as floating bearing.For this purpose, for example can also be by the outer shroud 6 axially in embodiment being not shown here
With the end regions 9 of housing 2（Referring to Fig. 1）Welded.
As in the first embodiment, the described three, the four, the 5th and the 6th is welded to connect 20,21,23,24 energy
It is enough not only to interrupt entirely around ground but also once or in multiple times in the second embodiment, or the angle to determine
Spacing is configured to point-like.
