Title:
CYLINDRICAL SLIDE BEARING OF ROTARY ELECTRICAL EQUIPMENT
Document Type and Number:
Japanese Patent JPS5977127
Kind Code:
A
Abstract:
PURPOSE:To prevent damage by heat, separation and breakage of a Babbit metal in a bearing of inner-outer cylinder system by providing the inner cylinder with a groove cooling hole at the back of a thick portion of a dovetail groove to unifomalize thermal expansion of the Babbit metal, thereby preventing rising of the Babbit metal and uniformalizing contact of the Babbit metal with a journal. CONSTITUTION:A bearing 3 comprises an inner cylinder 6 and an outer cylinder 7, wherein the inner cylinder is provided with a groove cooling hole 8 mounted at the back of a thick portion of a dovetail groove 12 to uniformalize thermal expansion of a thin portion and a Babbit metal 4, thereby preventing rising of the Babbit metal at the dovetail groove portion. Load can be supported on a rotary shaft uniformly at the whole surface of effective length of a bearing so as to prevent damage by heat, separation and breakage of the Babbit metal and prevent abnormal vibrations. Further, as the bearing can be used effectively and efficiently, the effective length of the bearing can be reduced more than before to improve economical efficiency.
