Vertical shaft support bearing - has downwardly facing annular slide face bearing on stationary member

摘要

The supporting bearing for a rotary vertical shaft includes a supporting bearing member attached to the shaft and arranged coaxially with it. The support bearing member has an inner cylindrical surface arranged with a radial clearance with respect to the shaft and a downwardly facing annular slide face bearing against a stationary bearing body. The cylindrical surface surrounds an annular space which contains a liquid lubricant and is limited radially inward by a stationary screen surrounding the shaft. The screen is formed of an inner hollow cylinder and an outer hollow cylinder arranged coaxially with respect to the inner hollow cylinder and with a radial clearance between them.
