IPC: F04B39/02
Filed: 1985-04-19
Abstract: PURPOSE:To prevent the scattering of lubricating oil from the end of an upper bearing and prevent the blowing-up due to the increase of differential pressure and further achieve the prevention of a shortage of lubricating oil by closing the lubricating oil suction hole provided in a turning shaft in the midway and communicating the space in the ring-form cover with the suction hole. CONSTITUTION:As the number of revolutions of an electric element 11 increases, a centrifugal pump action increases, and the lubricating oil quantity taken into a suction hole 4 provided in a turning shaft 3 increases, and further the lubricating oil quantity discharged from the upper end part of an upper bearing 5 increases. On the other hand, lubricating oil is also discharged from a gas vent hole 14 communicating the space of a ring-form cover 12 with the interior of the suction hole 4. althrough the lubricating oil like this is scattered away by the turning shaft 3 which is turning at high speed, the ring-form cover 12 collects this, and therefore the scattering into a closed vessel 1 can not be caused. Further, since the suction hole 4 is closed in the midway and is not communicated with the side of a discharge pipe 15, blowing-up due to the pressure difference can be prevented. Thus, the discharge of lubricating oil together with discharge gas outside the closed vessel 1 is not caused, and the burning of sliding parts due to the shortage of lubricating oil can be prevented.
