Hydraulic radial bearing

摘要

A work chamber is filled with a hydraulic liquid and is disposed between the legs of the spring body of a hydraulic radial bearing. The work chamber is connected to a compensating chamber via a transfer channel. The desired absorption of disturbing noises in the region of 130 Hz is obtained with a special dimensioning of the cross-sectional area of the work chamber, the dynamic swell stiffness of the spring body and the length (L) and the total cross-sectional area (A₂) of the transfer channel. The ratio of the effective cross-sectional area (A₁) of the work chamber to the cross-sectional area (A₂) of the channel lies preferably between 0.1 and 10 while the ratio of the length (L) of the transfer channel to the total cross-sectional area (A₂) of the transfer channel is in the range of 0.1 to 4.0.
