ABSTRACT:
An apparatus for grinding of internal, axially extending profiles, particularly for flanks on spline bore hub profiles and inner toothing, and driven by an electric motor, comprising a grinding arm of mandrel shape having a grinding wheel mounted on both sides therein, a toothed belt completely disposed inside of and running in the grinding arm operatively driving the grinding wheel. Gear wheels and the toothed belt thereabout are disposed in a channel formed in the grinding arm. An encapsulating shield completely encapsulates the grinding arm, the mounting for the grinding wheel, the toothed belt and the gear wheels. The channel constitutes a feed for oiled pressurized air to the mounting for the grinding wheel, and the grinding arm is formed with at least one separate grinding-oil channel adjacent the first mentioned channel for feeding grinding-oil to outside of the encapsulating shield adjacent the grinding wheel.
