Guide wheels for belt grinder

摘要

A pair of guide wheels (6) for a hand held abrading device (1) of the endless abrasive belt (2) variety for preventing slewing, side slipping and gouging of the surface of a workpiece (8) when a raised imperfection (9) such as a weld bead is abraded to be flush with the surface (10). The guide wheels (6), mounted on the axle (5) of the contact wheel (3) of the device, are circumferentially adjustable to compensate for different radial dimensions of the sum of the thickness of the abrasive belt and the radius of the guide wheel and include a resilient tire guide ring (11) and a circumferentially round guide surface (12) having different radii at different lateral positions.
