ABSTRACT:
A compact floor polisher is disclosed including a base supporting an electric motor having a vertically oriented output shaft and driving a circular brush. The base includes a depending annular skirt and a hollow hub. A brush carrier has an annular flange and a spindle rotatably supported by bearings within the hub. The brush carrier and support base define a lubricant housing. A ring gear is formed on the annular flange of the carrier and engaged by a pinion gear secured to the motor output shaft. A seal is disposed between the vertical flange and the annular skirt. A breather passage is defined by the base and extends into the lubricant housing. Baffles direct lubricant into the hub to lubricate the bearings supporting the brush carrier spindle.
