FIELD: the invention refers to the field of electrotechnique and may be used in industry and agriculture for carrying out stand testing of the bearings of electric engines.
SUBSTANCE: stand for testing bearings of electric engines on longevity has a bed with an opening for passing the rod of a stretched arrangement, pillars with fixed in them rotating centers and a tested engine. An eccentric is fastened on the shaft of the tested electric engine. It consists of two plates fixed between each other and from the inner side having cut-outs in which inserts are placed. From the outer side pins with carving are fastened to the plates. On each pin a balancing element is stringed whose position can be fixed.
EFFECT: creation of regulated rotating radial loading impacting on the bearings of the shaft of the electric engine, suitability to test electric engines of various dimensions.
