Problems solved by technology

[0007] However, there is no method or process disclosed in the prior art that allows the assembly of electric motors in order to avoid the subsequent steps of machining parts
It should be pointed out that all related projects have a common shortcoming, that is, they cannot be self-centering (auto centering), in other words, the size error of the components will directly affect the concentricity parameters between the bearings

Abstract

The present invention discloses an auto centering fitting system for the assembly of rotating electrical machines, comprising a couple of caps (1a) and (1b), wherein said cap (1b) shows a cylindrical geometry, optionally interrupted, comprising a strengthened peripheral region (3b) from which a male-type structure (6) complementary to the channel (4) of the cap (1a) extends longitudinally; and said cap (1a) shows a strengthened region (3a), from which a pair of symmetrical tabs (3c) project distally, which will define a fitting channel (4), forming a junction (5) through the application of axial pressure on both caps in opposite directions to each other, allowing for the fitting of (6) to (4).

Description

technical field [0001] The present invention relates to a self-centering system for use in rotating electrical machines, the system comprising a cover (bearing) and a base, one of which optionally has a discontinuous profile, thereby allowing the centering of said parts assembly adjustments and eliminates the need to machine them. Background technique [0002] Of all project specifications that have an impact on cost, dimensional tolerances are the most significant, directly affecting the economic viability of industrial scale. For a rotating electric machine to work smoothly, it is necessary to obtain sufficient concentricity between bearings to position the rotor and stator within a tolerable concentricity range. This condition often requires good dimensional accuracy of the structural components of the machine, which can be obtained directly from processing, or more often obtained through subsequent processing after manufacturing. Today, machining steps to correct for e...
