ball screw support bearings - midpoint bearing

2012-7-26Instead of ball transfer's rollerblade bearings can be used as support-bearings as well (see figure 6) This will make the construction a bit more complicated however: de 90 degree angle of the bearing mounting-blocks has to be exactly 90 degrees in that case Ball Bearing Test Facilities Fourteen vacuum chambers (nominal size 150 mm diameter) are available to measure bearing torque behavior (dc and noise level) continuously under thermal vacuum conditions Radial thermal conductance of ball bearings can also be measured The test chambers are also used for PVD bearing lubrication characterization

US4872767A

The invention comprises a compact support for a bearing associated with a rotating member such as a shaft of a gas turbine engine The bearing support has one or more circumferential leaf spring elements which provide radially resilient support for the shaft while being axially stiff to reduce axial thrust movement of the shaft The spring rate of the support is designed to shift engine
