A reliable, inexpensive option for the plates that function as wear parts and are mounted on an inner face of a casting wall of a stator. To achieve this the plates are designed as cast parts and are fixed to the inner face of the casting wall from an exterior of the stator. The plates are fixed by fixing bolts, which are screwed into the plates through the casting wall from the exterior. The plates have transverse threaded bores that correspond to the bolts. Respective spacer rings are pushed onto the fixing bolts secured by wedge-shaped cotters in both a positive and non-positive fit, and the wedge-shaped cotter pressing on the spacer rings that lie against the outer face of the casting wall. This invention is extremely economical and improves the operational safety in comparison to known options. |
