Eccentric grinder
First Claim
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.

Abstract
An eccentric grinder has a housing provided with a gear rim an eccentrically rotating grinding disc provided with a gear rim which rolls on the gear rim of the housing and in operation without load provides an additional rotary movement of the grinding disc. The gear rim of the grinding disc is 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 the rims relative to one another. The gear rim of the housing is fixed to the housing and includes a toothed rim which is formed by a ring-shaped toothed belt with a toothing while the gear rim of the grinding disc has a plurality of projections which incompletely engage in the toothing of the gear rim of the housing and therefore an elastic deformation of the projections gives the grinding disc a shaking movement with partial meshing under maximum slippage.
