LUBRICATION AND COOLING ELECTRIC MOTORS IN A VACUUM |
摘要 |
A lubricating system which is completely self contained within the vacuum environment of an electric direct drive system for an ultracentrifuge rotor. The lubricating system also functions as a cooling means for an electric motor within the drive system by the use of a unique cooling feed tube in the central portion of the drive system. An orifice in the top of the cooling feed tube will control the head of the lubricating medium within the system. Specific design of the fit between the direct drive assembly and the drive housing in conjunction with the head on the lubricating medium will regulate the drip rate of the lubricating medium to the bearings. The use of the unique lubrication and cooling system maintains the close tolerances of the various elements such as the high speed bearings of the drive system because the temperature of the overall drive system is controlled. |
