新型高速液体动静压轴承的温升机理

Mechanism of Temperature Raise for New Type High Speed Hydraulic Dynamic and Static Bearing

螺旋油楔高速动静压轴承的结构型式能加速润滑油的轴向流动 ,且两相邻油楔润滑油流动分开 ,使轴承的温升比普通轴承明显降低。其具有高抗振性、高承载能力、高精度和低温升等特点 ,是高速主轴单元理想的支承元件。附图 5幅。

The structure of helix wedge high-speed hydraulic dynamic & static pressure bearing is able to accelerate the axial flow of lubrication oil.Oil is separated between adjoining wedges, so the temperature raise of the bearing is evidently decreased than normal bearings. This bearing has better performance in vibration, loading capacity, accuracy and temperature raise.
