METHOD FOR MEASURING CLEARANCE OF MULTI-ROWS BEARING

摘要

PURPOSE: A method for measuring clearances of multi-rows bearings is provided to accurately measure clearances of bearings by controlling a displacement difference between outer races under a setting value. CONSTITUTION: A method for measuring clearances of multi-rows bearings is as follows. One row among electrically-driven outer bodies and one row among electrically-driven inner bodies are selected. Clearances occurred when the selected electrically-driven bodies, outer and inner races(20) are installed in a hub are measured. Two outer body rows or two inner body rows are selected. A displacement of the outer race occurred when a load is applied to the outer race is measured.
