Abstract

PURPOSE:To perform the circulation of oil to the bearing in a reverse rotation by providing an oil groove at the inner wall of collar and by forming a reversing pump between the collar and the inner wall of oil tank. CONSTITUTION:A spiral oil groove 14 for reverse operation is provided to the shaft collar 13 fixed to the rotary shaft 1 at the location in which the collar faces to the inner wall of oil tank 9, and a reversing screw oil pump 15 is formed in the gap between the collar and the inner wall of the oil tank. Also it is formed so that H1<H2. Where H1 is of the head in reversing the forward rotation screw oil pump 7. H2 is of the head in reversing the reversing screw oil pump. The oil is circulated by the difference DELTAH between both the heads. Because the head of reversing screw oil pump 15 is higher in a reverse operation, the oil is fed to the upper side of the bearing 5 by the reversing screw oil pump 15 to lubricate the bearing.
