A bearing device for rotors in miniature motors

摘要

A bearing device is disclosed for a miniature motor of the type in which a stator is formed within a cylindrical housing (1) closed at one end and fitted with an end plate (6) at its open end, and a rotor (5) is rotatably supported by bearings (9, 10) provided on the closed end of the housing (1) and the end plate (6). The device has a retaining body (30) with a flange (21) and a base (22), both annular in shape, connected by a plurality of axially extending and circumferentially disposed connecting members (23). A plurality of axially extending support columns (24) shaping a basket project towards the flange (21) from the bottom member (22). The device is fitted to a mounting element on the housing end and/or the end plate (7), and a spherical bearing bush is supported resiliently between the supporting columns (24).
