1. An eccentric grinder, comprising a housing provided with a gear rim;

  • an eccentrically rotating grinding disc provided with a gear rim which rolls on said gear rim of said housing and in operation without load provides an additional rotary movement of said grinding disc, said gear rim of said grinding disc being a friction rim so that in operation without load there is a minimum slippage and in operation under load there is a maximum slippage of said rims relative to one another, said gear rim of said housing being fixed to said housing and includes a toothed rim which is formed by a ring-shaped toothed belt with a toothing while said gear rim of said grinding disc has a plurality of flexible projections which incompletely engage in said toothing of said gear rim of said housing and therefore an elastic deformation of said flexible projections gives said grinding disc a shaking movement with partial meshing under maximum slippage.
