IPC: F16C19/18
Filed: 1999-11-29
Abstract: PROBLEM TO BE SOLVED: To prevent an inner ring from falling off without impairing the disassembling/ assembling characteristics and performance. SOLUTION: A gear device for rolling stock fitted with a small gear shaft 13 and a large gear 14 is rotatably supported by a single flanged cylindrical roller bearing 18 and a double flanged cylindrical roller bearing 17. A roller 18b is smoothly rotated on an opposite surface 18aa of a single flanged part 18a of the single flanged cylindrical roller bearing 18 with respect to the roller 18b, or a thrust direction gap between the single flanged part 18a of the single flanged cylindrical roller bearing 18 and the roller 18b is properly specified as required so that a thrust load is applied also to the single flanged part 18a of the single flanged cylindrical roller bearing 18. The flange part 18a of the single flanged cylindrical roller bearing 18 acts as a stopper, and the inner ring of the double flanged cylindrical roller bearing 17 is prevented from falling off.  When the roller 18b is smoothly rotated on the opposite surface 18aa, troubles such as an interference and sticking between members, and so on, are not caused even in case of the falling off of the double flanged cylindrical roller bearing. When a thrust load is applied also to the single flanged part 18a of the single flanged cylindrical roller bearing 18, a danger of falling off of the inner ring of the double flanged cylindrical roller bearing 17 is securely reduced.
