According to the invention, the fastening part (15a, 15b, 15c, 15d) is formed by bending over a part of the circumference of an edge part (4a, 4b, 4c, 4d) of the stator (1), which edge part is partially cylindrical and extends continuously along the circumference before the bending over.
Description
Technical field
The present invention relates to a kind of by claim 1 stator arrangement that is particularly useful for the windshield wiper device as described in the preamble.
Background technology
For example at US 6,343, a kind of stator arrangement has been shown among the 403B1, in this stator arrangement, the pole shoe of electrical motor is fixed on the gear mechanism housing.
For pole shoe is fixed on the gear mechanism housing, different technique for fixing schemes is disclosed.By means of bolt of rear end plate the scheme that pole shoe is fixed on the gear mechanism housing is extensively promoted, this bolt of rear end plate passes the utensil receiving opening in the holding flange of pole shoe and tightens with gear mechanism housing.Shortcoming when using bolt of rear end plate is that extra independent Connection Element (bolt of rear end plate) must be set.Disclose in addition, described pole shoe is fixed on the gear mechanism housing by the roll extrusion crimping.Thus, the columniform edge section of described pole shoe shift onto vertically gear mechanism housing have around the columniform holding flange of groove on, then will along the circumferential direction in diel, rotate in the past by the device that pole shoe and gear mechanism housing are formed, this diel radially affacts on the pole shoe and this pole shoe inwardly is deformed in the circumferential groove of gear mechanism housing flange, forms form fit thus and connect between pole shoe and gear mechanism housing.In the method for the disclosure, advantageously, extra connecting element such as bolt of rear end plate needn't be set on pole shoe.Shortcoming is the time-consuming roll extrusion crimping of these two structure members, and the roll extrusion crimping needs the higher manufacturing equipment of cost.
The another kind of fixing means that does not need extra connecting element is that the corresponding bended edge around gear mechanism housing will be stamped into the pressing plate interlock in the edge section of pole shoe.In this method, advantageously, needn't carry out the twisting motion of pole shoe and gear mechanism housing along diel.Yet shortcoming is, making in the deepdraw pole shoe is the cost costliness, is flushed in the pole shoe edge that at first along the circumferential direction extends continuously because must will remain crooked pressing plate extraly/additionally.
Summary of the invention
Task of the present invention provides a kind of stator arrangement, do not need with independent connecting element pole shoe to be fixed on the gear mechanism housing in this stator arrangement, and this pole shoe has as far as possible simply structure in this stator arrangement.

The present invention is based on this design, that is, do not have to remain a crooked canned paragraph to be configured to be flushed to pressing plate in the edge section of pole shoe, but form at least one canned paragraph by bending is the columniform edge section of part before bending segment section.In other words, only when carrying out fixing step, the circumferential segment that is the columniform edge section of part by bending before this just forms described at least one canned paragraph.Before bending, described at least one edge section along the circumferential direction continuously, that is to say not interruptedly, promptly be not provided with punching press mouth ground and extend.At this, before the canned paragraph of described edge section under crooked shell portion with end seamed edge of describing the part circle.Thus, pole shoe can be configured to not have the simple deep-draw part of the maintenance feature as pressing plate that pours or holding flange because carry out real need not be previous fixedly the time pour step but construct described canned paragraph by along the circumferential direction continuous material by bending.At this, described canned paragraph itself and gear mechanism housing amalgamation interlock in other words, thus realize that the form fit between pole shoe and the gear mechanism housing connects.Prevent thus described pole shoe under the state that fixes with respect to gear mechanism housing reverse and housing between axial motion.With respect to disclosed roll extrusion crimping method, significantly reduced the needed processing equipment cost of Fabricating machinery in other words, because needn't fixedly the time, realize twisting motion.For pole shoe is fixed on the gear mechanism housing, only need crooked formed punch, pole shoe tip edge piecewise is centered on the bended edge bending of gear mechanism housing by means of crooked formed punch.Do not need independent connecting element such as bolt of rear end plate yet.
Advantageously, all edge sections merge the continuous columniform pole shoe edge of formation in improvement project of the present invention.In this case, " continuous " means that also each canned paragraph along the circumferential direction interruptedly is not extended in the affiliated edge section in the bending step both sides previous dynasty at least.In this embodiment, the seamed edge of described edge section has been described a complete circle jointly before bending.In case of necessity, this complete circle is interrupted by one or more centering machine grooves, yet this centering machine groove does not keep function.
In one embodiment, described canned paragraph arranges evenly distributedly that on the circumference of pole shoe this embodiment is preferred.Four canned paragraphs that are evenly distributed on the circumference are set prove favourable, wherein Suo Shu edge section has been described the quadrntnt post before bending.
To be connected in order forming, holding flange advantageously to be set on gear mechanism housing to be used for fixing pole shoe, at least one bended edge is set on this holding flange is used at least one canned paragraph with the form fit of gear mechanism housing.At this, described holding flange preferably has the diameter littler than pole shoe edge, makes described pole shoe to be enclosed within vertically on the holding flange, and then the pole shoe edge by bent cylindrical forms canned paragraph.
In order to be provided for holding the spatial accommodation of the crooked canned paragraph of piecing together interlock in other words on the holding flange of gear mechanism housing, the zone in the inner radial of the circumference seamed edge of the formation bended edge that is arranged in the gear mechanism housing flange in design plan of the present invention is provided with groove.Preferred described bended edge form the described groove of boundary trough end wall along the circumferential direction extend, outside border radially, described groove extends to described trough end wall vertically.
The preferred radially outwardly open circumferential groove of structure in described holding flange can be inserted seal ring when needed or injected this circumferential groove, so that described pole shoe obtains sealing and avoids moisture to enter thus with respect to gear mechanism housing.
Correctly directed in order to ensure the pole shoe that comprises CD-ROM drive motor with respect to gear mechanism housing, at least one centering machine is set, the other centering machine combined action on this centering machine and the gear mechanism housing on described pole shoe in improvement project of the present invention.In case of necessity, the centering machine of described pole shoe is configured to the punching in the edge section of pole shoe.Yet because described centering machine does not have fixed function, just not around the bended edge bending, so do not leave scope of the present invention thus.For fixing purpose, pre-punched hole (Vorstanzungen) is not set in the edge section of described pole shoe.
