摘要： An electrocorrosion preventive rolling bearing assembly comprises an inner raceway; an outer raceway; circumferential row(s) of rolling elements between respective raceway grooves of the inner and outer raceways; an electrically insulating layer formed on the inner and/or outer raceways; and a tool reference plane for finishing or for controlling the thickness of the insulating layer. An electrocorrosion preventive rolling bearing assembly comprises an inner raceway; an outer raceway (3); circumferential row(s) of rolling elements rollingly interposed between respective raceway grooves of the inner and outer raceways; an electrically insulating layer (6) formed on the inner and/or outer raceways so as to cover a peripheral surface and opposite annular end faces (3b, 3c) of the inner and/or outer raceways, the peripheral surface of the inner and/or outer raceways is engageable with a housing or a shaft; and a tool reference plane (7) defined in at least one of opposite sides of the raceway groove of the raceway. The tool reference plane is utilizable for a process of finishing the electrically insulating layer or for a thickness control of the insulating layer.

摘要： PROBLEM TO BE SOLVED: To provide a dressing device for crowning grinding wheel capable of ensuring high precision without being affected by external disturbance and facilitating the adjustment. SOLUTION: A differential transformer type displacement sensor 4 detecting a shape of a circular arc cam 2 is attached to a slide table 3 of a grinding machine, an analog controller 5 setting a span of an output voltage and a piezodriver 6 amplifying an output voltage are connected with an output terminal of this displacement sensor 4, a positioner 8 in which a piezoelement is assembled is operated by the amplified voltage, and a holder 10 of a diamond tip 9 is moved relatively along a grinding wheel 14 face so that the grinding wheel 14 can be dressed to an arbitrary crowing amount set by the analog controller 5.
