    摘要： The disclosure relates to a flange including a flange body (12) and an oil supply unit for securely fixing a tool (24) to a rotary shaft (26). The flange body (12) has inner and outer peripheral surfaces and has a plurality of pressure oil chambers (14, 15) formed therein in axially spaced relation to one another. Each of the pressure oil chambers (14, 15) extends circumferentially of the flange body (12) and is disposed adjacent to the inner peripheral surface of the flange body (12) in such a manner as to define a wall portion (W 1 ; W 2 ) between the inner peripheral surface of the flange body (12) and a respective one of the pressure oil chambers (14; 15). The oil supply unit is formed to supply the plurality of pressure oil chambers (14, 15) with a pressurized oil to cause the wall portions (W 1 , W 2 ) to protrude radially inwardly of the flange body (12), whereby when the flange body (12) is fitted on the shaft (26), the flange body (12) is pressed against the shaft (26) with each of the wall portions (W 1 , W 2 ) held in abutting engagement with the outer peripheral surface of the shaft (26).

    摘要翻译： 本发明涉及一种凸缘，其包括用于将工具（24）牢固地固定到旋转轴（26）的凸缘体（12）和供油单元。 凸缘体（12）具有内周表面和外圆周表面，并且在其中彼此轴向间隔开地形成有多个压力油室（14,15）。 每个压力油室（14,15）沿着凸缘体（12）的周向延伸，并且与凸缘体（12）的内周面相邻配置，以限定壁部（W1; W2 ）在凸缘体（12）的内周面与相应的一个压力油室（14; 15）之间。 供油单元形成为向多个压力油室（14,15）供给加压油，使壁部（W1，W2）向凸缘体（12）的径向内侧突出，由此当凸缘体 （12）安装在轴（26）上，凸缘体（12）被压靠在轴（26）上，其中每个壁部分（W1，W2）保持与轴的外周表面邻接 26）。
