Brush holder assembly for an electric motor

A universal motor has a brush cage assembly in which a U-shaped clip 34 is located about a wall of a through hole 28 of a bearing bracket 24 for receiving a brush cage 30. The clip 34 has an outer limb 42 with inwardly and rearwardly directed barbs 44 to grip an outer surface of the wall to prevent removal of the clip 34 and an inner limb 36 with outwardly and forwardly directed barbs 42 which resiliently deform as the cage 30 is inserted to snare the cage 30 should it move in the opposite direction. The clip 34 thus prevents withdrawal of the brush cage 30 and provides a lateral spring force against the cage 30 to reduce cage lateral position tolerance and movement.

Forming method of superplastic forming/diffusion connecting four-layer structure of grid with variable depth-width ratio

The invention relates to a forming method of a superplastic forming / diffusion connecting four-layer structure of a grid with variable depth-width ratio, and belongs to the technical field of surface wrinkle prevention, and the surface of the four-layer structure formed by virtue of the method is flat and winkle-free. According to the method, in the process of forming a core board into a grid, the grids with different depth-width ratios are different in expanding start time, i.e., the grid with higher depth-width ratio is formed before the grid with lower depth-width ratio, and the grids with approximate depth-width ratios are approximate in expanding start time, so that the contact start time of each grid and a panel at the position of the grid is approximate; meanwhile, in the grid forming process, the air pressure between the panel and the core board is always kept high, so that the part, which is contacted with the panel, of the grid is not subjected to diffusion connection immediately in the expanding process; due to the effects of two aspects, the problem that the panel draws back along with deformation of the core board in a grid continuous expanding process can be prevented, and thus wrinkles are prevented from occurring.
