Overview of technical requirements for zirconia ceramic bearing support for shafts

Overview of technical requirements for zirconia ceramic bearing support for shafts

The shaft is supported by zirconia ceramic bearings, and the shaft segment matched with the bearing is called the journal. The journal is the assembly benchmark of the shaft, and their accuracy and surface quality are generally required to be high. The technical requirements are generally formulated according to the main function and working conditions of the shaft, and usually include the following items:

(1) Dimensional accuracy of zirconia ceramic bearings

In order to determine the position of the shaft, the journal of the zirconia ceramic bearing that supports the bearing usually requires high dimensional accuracy (IT5~IT7). The dimensional accuracy of the journal for assembling transmission parts is generally low (IT6~IT9).

(2) Geometric accuracy of zirconia ceramic bearings

The geometric accuracy of zirconia ceramic bearing parts mainly refers to the roundness and cylindricity of the journal, outer cone surface, Morse taper hole, etc., and its tolerance should generally be limited within the dimensional tolerance range. For the inner and outer circular surfaces with high precision requirements, the allowable deviation should be marked on the drawing.

(3) Mutual position accuracy of zirconia ceramic bearings

The position accuracy requirements of zirconia ceramic bearing parts are mainly determined by the position and function of the zirconia ceramic shaft in the machine. Usually, it is necessary to ensure the coaxiality requirements of the journal of the assembly transmission parts to the support journal, otherwise the transmission accuracy of the transmission parts (gears, etc.) will be affected and noise will be generated. For ordinary precision zirconia ceramic shafts, the radial runout of the matching shaft section to the bearing journal is generally 0.01~0.03mm, and the high-precision shaft (such as the main shaft) is usually 0.001~0.005mm.

(4) Surface roughness of zirconia ceramic bearing

The surface roughness of the shaft diameter of the zirconia ceramic bearing generally matched with the transmission part is Ra2.5~0.63μm, and the surface roughness of the support shaft diameter matched with the zirconia ceramic bearing is Ra0.63~0.16μm.
