Abstract
The sealed electromotor bearing has its bearing wear measured by the following means. An electrically-conducting rod has a pair of radial projections at one end and the outer surface of the rod and of the projections is coated with an insulating layer. A terminal tag is connected to the other end of the rod and to a relay. The insulating layer on the projection wears down through use and causes an electrical connection to a contact on the end of the rotor shaft and the relay is operated. The insulator is made from a synthetic resin with high corrosion resistance, for example ethylene hexafluoride, with a thickness of (0.2mm).
