Description
Technical field
The present invention relates to a kind of electro-motor, and it has housing and rotor, and the rotor supports via fixation/floating support portion
In the housing, wherein, the deep groove ball bearing with inner ring and outer rings is arranged to fixing bearing, and the outer shroud of fixing bearing is borrowed
Spring steel plate washer is helped flexibly to clamp in the housing.
Background technology
Form according to the spring steel plate washer of the present invention is known in itself, and this is commonly used especially in spherical bearing
Class formation element.It is that in spherical bearing, torque is not applied to axially by axle with the main distinction of the generic of the present invention
On bearing.In contrast, deep groove ball bearing inner ring securely with shaft compression in the case of, have very big axial load quilt
It is delivered on bearing, especially in the case of oscillating load and impact load.
The content of the invention
The task of the present invention is, by simple means, with method and step as few as possible and a small amount of component by zanjon
Ball bearing is reliable and is permanently fixed in the steel sheel through deep-draw.The task is according to the invention through the features of claim 1
Solve.
It is proposed that housing is the steel sheel (10) through deep-draw or the steel sheel tank through deep-draw, spring steel plate washer (5) warp
Hardening, the hardness of spring steel plate washer (5) is more than the hardness of the steel sheel (10) through deep-draw, and spring steel plate washer (5) has card
The form of tight ring, it has the ring part of closure in the region of the radially outer of outer shroud (9), and the ring part of the closure has footpath
To the spring arm (2) being directed inwardly toward, spring arm loads outer shroud (9) as follows, i.e. each spring arm (2) is with the sum of axial direction
The force component of radial direction is applied on outer shroud (9).Because the hardness level of engagement mating member (F ü gepartner) is different so that
When opposite with direction of engagement power loading occurs, spring steel plate washer (5) is tightly stuck in the steel sheel through deep-draw (10) and reliably
Ground is kept.The outer shroud (9) of deep groove ball bearing (8) can be supported in steel sheel (10) and only by spring steel pad with axial motion
Piece (5) is kept.When the power loading opposite with direction of engagement occurs, force component axially and radially is applied on spring arm (2),
Thus, more or less deflected depending on the numerical value of these spring arm eyesights, so that the adjacent end of spring arm (2)
Spacing slightly increases.In the case of the ring part of closure, this effect can cause hardened component to be broken.It is because illustrated
The connection of force closure (kraftschl ü ssig) have been found to be sufficiently tight, so the safety element that need not add or
Reshaping process.It thus provides fasten to the very simple of deep groove ball bearing (8) and effectively.
The improvement project of the present invention is shown in the dependent claims.Particularly advantageously, steel sheel (10) is zinc-plated
's.It is that very thin zinc layers still result in confining force of the spring steel plate washer (5) in steel sheel (10) and substantially increased after deep-draw
It is high.
In addition it is claimed, steel sheel (10) has multiple stepped depressed parts (11,12,13), and first
Depressed part (11) is radial through the first cylindricality side face (21) gauge and for accommodating spring steel plate washer (5).The depressed part (11)
It is sized as follows in diametrically, i.e. it is sufficiently used for accommodating spring steel plate washer (5).
In addition propose, steel sheel (10) has the second depressed part radial through second cylindricality side face (22) gauge
(12), its interior diameter is less than the interior diameter of the first depressed part (11), and the second depressed part (12) is used to accommodate deep groove ball bearing
(8).The interior diameter of second depressed part (12) is different from the interior diameter of the first depressed part (11), so as to which spring arm (2) is obvious radially
Ground is extended in the region of the second depressed part (12), so that the outer shroud (9) of deep groove ball bearing (8) can be in axial direction by bullet
Spring arm (2) is kept.
Desirably, steel sheel (10) has the 3rd depressed part (13), and it is radial through the 3rd cylindricality side face (23) finally
Gauge and its interior diameter are less than the interior diameter of the second cylindricality side face (22).The depressed part (13) designs as follows, i.e. energy
It is enough reliably to assemble cover (16).When needing shell nozzle so as to realize the dress for being pressed into inner ring on motor drive shaft
During accessibility with instrument, cover (16) can be necessary.
It is of special importance that the outer shroud (9) of deep groove ball bearing (8) axially have than the second depressed part (12) depth more
Big size.Only thus, gapless receiving of the outer shroud (9) in the second depressed part (12) could be realized.
It is advantageously provided, spring steel plate washer (5) is in axial direction resisted against on stopper section (6) in the assembled condition.
The axial location of stopper section (6) is conclusive for pretension, and spring arm (2) is applied on outer shroud (9) using the pretension.By
This, and because dimensional tolerance, engagement mating member can realize the power that can be limited within the computable margin of tolerance.
It is provided that, spring steel plate washer (5) has the clamping region (4) of tapered side face form, and spring steel plate washer is filling
With under state utilize the clamping region fix on the inwall of the first cylindricality side face (21) of steel sheel (10).Occurring with engaging
Holding of the spring steel plate washer (5) in steel sheel (10) is improved due to geometry rule when power in opposite direction loads, this is
Because clamping region (4) phase radially outer extruding of tapered side face form, thus strengthens power again in the case of specified
It is sealed.
It is distinctly claimed, deep groove ball bearing (8) is only locked by the power of spring steel plate washer (5) and steel sheel (10)
The connection of conjunction is kept, to realize the task of the present invention.
The other important advantage of the present invention is that deep groove ball bearing (8) is held resiliently by spring arm (2).Thus
Radial load can be buffered, without permanent deformation.
Also meaning, axially refer to along the outer shroud (9) from deep groove ball bearing (8) of disassembly direction towards spring arm (2)
To power improve and be radially applied to the power on the first cylindricality side face (21) from clamping region (4).
It has been proved that the spring arm (2) of spring steel plate washer (5) under unassembled state should relative to pad plane with
25 ° to 35 ° inclinations, the clamping region (4) of spring steel plate washer (5) should be relative to pad plane with 35 ° under unassembled state
To 45 ° of inclinations, and the overall diameter in the clamping region (4) of spring steel plate washer (5) should be than the first cylindricality under unassembled state
The interior diameter big 2% to 4% of side face (21), to facilitate the optimal confining force of spring steel plate washer and to deep groove ball bearing (8)
Optimal elastically keep.
Present invention additionally comprises following housing, it has more more recessed than listed depressed part (11,12,13)
The portion of falling into.In this case, " the first depressed part " refers to accommodating the depressed part of spring steel plate washer (5).
