Abstract
A shaft bearing assembly, particularly for a miniature electric motor. In the case of the present shaft bearing assembly, an oil-impregnated dampening disc made of an absorbent material the capillary action of which is greater than that of the porous bearing block is disposed between the thrust collar of the shaft and the axial end face of the bearing block. The shaft bearing assembly is particularly suitable for electric motors of smaller size and is effective in reducing motor noise.
