Bearing chamber for vertical pump

Abstract

The invention discloses a bearing chamber for a vertical pump. The bearing chamber comprises a vertical bearing chamber cavity provided with stepped holes. The bearing chamber is characterized in thatthe inner wall of the vertical bearing chamber cavity is fixedly connected with two or more inwards bulged bearing outer ring supporting rib plates in a spaced manner; each bearing outer ring supporting rib plate comprises a radial supporting block provided with an inner arc surface, and a longitudinal supporting step fixedly connected with the lower end of the radial supporting block; the innerends of the longitudinal supporting steps are located on the inner sides of the inner arc surfaces; and the two side surfaces of each radial supporting block are oblique surfaces and a certain included angle is formed between each oblique surface and the vertical direction. The contact areas between lubricating oil and the inner wall of the bearing chamber and between the lubricating oil and a bearing outer ring can be increased, the lubricating and heat dissipation effects are improved substantially, an oil storage space is increase d, and normal working of the vertical pump is ensured for along time.

Description

technical field [0001] The invention relates to a bearing chamber, especially a bearing chamber for a vertical pump. Background technique [0002] At present, regardless of the bearing chamber used for vertical pumps or horizontal pumps, there is an integral bearing seat inside to support the outer ring of the bearing on the pump shaft; but for vertical pumps, there is lubricating oil under the bearing seat The disadvantages of the pool are: due to the blocking effect of the integral bearing seat, the lubricating oil brought up during work is difficult to contact with the inner wall of the bearing above and the bearing seat, which is not conducive to heat dissipation. Long-term operation will affect the normal operation of the pump, and The oil storage space of the bearing chamber is also limited, which also reduces the lubricating and cooling effects. Contents of the invention [0003] The purpose of the present invention is to address the above-mentioned deficiencies in...
