Patent ID: 8672729

Claim:
A device for polishing a wheel, said device comprising a rotative assembly ( 20 ) and support means therefor, said rotative assembly ( 20 ) comprising a combination of an electric motor ( 46 ) having a rotational speed of 1800 rpm with two reducers for reducing the rotation speed thereof, a primary reducer ( 30 ) of a ratio of 10:1 and a gear reducer ( 26 ) of a ratio of 60:1, said reducers being connected through a coupling plate ( 44 ), said coupling plate having an axial center ( 94 ) coinciding with a common axial center of said two reducers; said gear reducer comprising a drive-shaft ( 28 ) powering a wheel holding jaw ( 36 ); said coupling plate ( 44 ) comprising means of bolts to fix said two reducers to said coupling plate, said primary reducer positioned relative to said gear reducer by an angle ( 34 ), thus maintaining a top face of said primary reducer at said angle ( 34 ) relative to a top face of said gear reducer, thereby maintaining a level of oil allowing the lubrication of the internal parts of said primary reducer thus rendering said device auto lubricating; said angle ( 34 ) being 15°±3°; wherein said support means is a stand ( 22 ) comprising a support plate ( 24 ) to support said rotative assembly and an angular folded knee member ( 62 ), said stand being mounted on a pendulum ( 23 ) for maintaining it in balance upon a floor and said plate obliquely with respect to said floor, a linear actuator ( 42 ) positioned between said stand and said pendulum and causing an angular positioning of said knee member, said stand ( 22 ) comprising two horizontal legs ( 60 , 60 ′) with an elbow ( 62 ) and a top part ( 64 ) supporting said support plate ( 24 ), on said legs a V-shaped support ( 61 ) comprising at its ends openings ( 67 ) to insert small wheels ( 69 , 69 ′) to move said assembly, said top part including an arch ( 65 ) with a tip ( 66 ) to attach thereto said means of positioning.
