| 摘要 |
The present invention relates to a device for testing the radial bearings, applicable for determining the static operating characteristics as well as the bearing capacity and the moment of friction in the bearings, and it is used for testing the radial bearings, particularly the high speed hydrodynamic radial bearings According to the invention, the device comprises a tubular axle (8) and a radial bearing (5) to be tested, said bearing being mounted into a housing (4) Under the housing there are provided thread-adjustable subassemblies (1) which can generate the eccentricity (e) of the radial bearing (5) relative to the tubular axle (8), said eccentricity being controlled by means of the displacement transducers (9) The thread-adjustable subasemblies (1) are supported by force cells (3) which can measure the bearing capacity and the moment of friction which load the radial bearing (5) to be tested
