Nassläuferpumpe

摘要

The object of the invention is to reduce wear on bearings and shaft to the extent of ensuring troublefree and low-noise continuous use, and at the same time minimising the material outlay and manufacturing effort. To this end, according to the invention there is provided for a dishwasher pump, a combination of a rotor shaft (3) made of austenitic steel and plastic bearing bushes (6 and 7, respectively) with incorporated lubrication or, for a washing appliance suds pump, a combination of a rotor shaft (3) made of ferritic steel with at least a hardened bearing surface and a plastic bearing bushing (6 and 7, respectively), having a high modulus of elasticity due to the addition of fibrous materials.
