Abstract
A self-acting air bearing operable at very high speed in a non-vertical spin axis in a beam scanning optical system provides precise rotation of a rotable hologon disk. Pretreatment of the bearing surfaces with a residual boundary lubricant allows reliable operation over an extended series of start/stop cycles. The tilt of the bearing/disk assembly allows the construction of an optical system more compact than in conventional hologon beam scanning systems.
Claims14
An improved self-acting cylindrical air bearing system for rotation of a beam deflection means, comprising:
- a bearing spindle;
- a bearing sleeve received by the spindle, the spindle and sleeve having respective bearing surfaces displaced by a bearing gap, and at least one bearing surface being subject to rotation with respect to the other bearing surface;
- and
- a residual layer of boundary lubricant formed on at least one of the first and second bearing surfaces.
