Document Type and Number:
Japanese Patent JPS57195995
Kind Code:
A
Abstract:
PURPOSE:To prevent lubricant from touching a rotary body, by arranging an oil receiving member receiving the lubricant dropping from a bearing and a thread groove sending forcibly the received lubricant to the oil guide hole of a rotary shaft. CONSTITUTION:An upper side rotary shaft 2 protruding upward and a lower side rotary shaft 3 protruding downward are fixed on a rotary body 1. On the other hand, the lower end portion of a funnel like oil receiving member 10 arranged under a bearing 5 is fixed on the upper side rotary shaft 2, and a thread groove 11 is cut airtightly in the inner periphery of the rising portion 10a of its upper end portion. The thread groove 11 is cut so as to advance downward along the oil rotating direction of the oil receiving member 10. The lubricant received in the receiving member 10 is discharged from a discharge hole 16 through an oil guide hole 13 drilled in the rotary shaft 2 and through holes 14 drilled in the rotary body 1 by the action of this screw pump. Accordingly, it is prevented that the lubricant overflows from the upper edge of the oil receiving member 10 and sticks to the surface of the rotary body 1.
