CANADIAN PATENT APPLICATION OF OLLE LENNART SIWERSSON and TORSTEN LOODBERG FOR METHOD AND APPARATUS FOR DETERMINING THE CONDITION OF A ROOLING BEARING Abstract of the Dicslosure: In a method and an apparatus for determining the condition, primarily changes in geometry, of a rolling bearing having a roller cage with rolling elements which are adapted to roll on the races of two thus relatively movable parts, the displacement of the roller cage rela- tive to one of the two parts is sensed simultaneously as the displacement of the other movable part relative to one of the two relatively movable parts or the roller cage is sensed, and the sizes of the two sensed displace- ments for one and the same time are determined. The mu- tual relation between the sizes determined is compared 1a with a reference value for the relation, whereupon the condition of the bearing is indicated in dependence on the result of the comparison. A monitoring means for rolling bearings includes a generator for supplying power to the electronic devices and circuitry of the means, which generator is driven by relatively movable parts of the bearing and prefer- ably combined with a chargeable battery, a detecting device for detecting the condition of the rolling bear- ing, an indicating device for indicating the detected condition, and an adjusting device for adjusting the monitoring means at the mounting thereof. 1b
