Rolling bearing arrangement for an electromotor

Abstract

The invention relates to a rolling bearing arrangement for an electrometer that essentially comprises a rotationally symmetrical rotor (2) arranged rotatably inside a stator (1), there being provided for rotationally bearing the rotor (2) at least one standard rolling bearing (3) that has an outer ring (5) which is arranged in a bearing seat (4) in a fixed position relative to the stator (1) and which cooperates via a rolling body arrangement (6) with an inner ring (8) arranged on a shaft (7) of the rotor (2), the bearing seat being lined with an insulation arrangement in order to avoid a flow of current between stator and rotor, specifically the bearing seat (4) of the outer ring (5) is lined with the insulation arrangement (9, 10a, 10b), the insulation arrangement having a thin, sheet-type semifinished product having insulation material resistant to the pressure of the radial force of the bearing.
