Definitions
- the present invention is part of the field of technologies dedicated to devices/elements for joining or fixing construction elements or parts of rotating electrical machines. More specifically , the present invention refers to a thin plate weldable to thick plates of rotating electrical machines , which provides a fastening solution by means of a threaded element , dispensing with the execution of additional machining operations . Additionally, a method is provided for fixing a component to a rotating electrical machinery structure by means of a secondary plate, provided with a threaded element.
- Document CN 209398718 U discloses a fastening device and automobile with the same. Such a document is concerned with the problem of space for positioning the screwdriver.
- the proposed solution is a plate with a hole in the shape corresponding to the geometry of the nut (or screw head), in order to accommodate it and promote the "self-torque" of the screw inside its thread.
- the document is not concerned with the problem of fixing thick plates, nor does it apply something similar to the proposed solution of joining thin plates with rivets welded to the main structure of thick plates. Additionally, such document does not teach about the problem of sealing between riveted surfaces.
- document WO 2018/094308 discloses that the nut plate is provided with an additional flat section that comes to rest against the body of the vehicle, that is, on top of the body of the vehicle, where it is then soldered.
- the present invention discloses a plate, thinner than a thick plate, which is then welded in a cutout in a thick plate of electrical machines.
- Figure 3 is a perspective view of a thin plate with a threaded element
- FIG. 6 is a bottom enlarged view of an illustrative electrical machine frame in which a plate with a threaded element is attached to a thicker plate.
- the secondary plate 100 comprises:
- the at least one threaded element 120 is preferably one of an internal thread, a threaded rivet or a threaded plug.
- the at least one threaded element 120 can be formed in the plate portion 110 itself with an internal thread, through or blind, and this plate portion 110 has a thickness smaller than the primary plate 210, also called thick plate 210.
- the use of a threaded rivet as the at least one threaded element 120 is defined as a preferred configuration.
- the plate portion 110 further comprises at least one opening in a generally central region thereof in order to receive and fix the at least one threaded element 120 in the plate 100 .
- the at least one opening of the plate portion 110 is manufactured before the plate 100 is attached to the structure 200 .
- the one or more cutouts 220 are positioned in any portion of the thick plate 210, preferably being positioned along an edge of at least one thick plate 210.
- a method for attaching a component to a thick plate 210 of a structure 200 of a rotating electrical machine by means of a thinner plate 100, provided with an element threaded 120 , as previously described .
- Said method comprises at least the steps of:
