Title:
静圧流体軸受装置、静圧流体軸受装置を用いた工作機械用主軸装置及び静圧流体軸受装置の製造方法
Document Type and Number:
Japanese Patent JP6476910
Kind Code:
B2
Abstract:
A hydrostatic bearing apparatus includes a bearing metal having a hydrostatic portion that allows a grinding wheel shaft to be rotatably supported. The hydrostatic portion has a bearing clearance, a bearing surface portion, a plurality of pockets, and partition plates. Clearances are each formed between the corresponding partition plate and an edge of the corresponding pocket in a rotating direction of the grinding wheel shaft. The clearances are formed in the pocket at upstream and downstream ends in the rotating direction. The bearing clearance has a first bearing clearance and a second bearing clearance. The second bearing clearance is larger than the first bearing clearance.
