RAIL GRINDING MACHINE FOR GRINDING RAILS OF A TRACK

摘要

A rail grinding machine for grinding rails of a track includes a machine frame with rollers for support on both rails of the track and a swivel drive for swingably mounting a carrier frame to the machine frame for rotation about a pivot axis which extends longitudinally in direction of the track. A grinder is adjustably secured to the carrier frame in an area of one rail, with a drive motor for supplying energy to the swivel drive and the grinder being secured to the machine frame at an area distant to the carrier frame. The distance of the carrier frame and its pivot axis from a support roller located opposite to the grinder is reducible by a length compensation unit which includes a pressure-exerting element for applying in opposition to the distance reduction a force by which the grinder is pressed against a rail head inner flank of the rail being ground.
