Lubricating device of tunnel die bearing of bracket axle of engine

摘要

(57) Abstract Objective Lubricating encountering of tunnel die bearing of bracket axleAs the te, the oil neutron leakage is decreased, lubricating performance is raised,The lubricating device is produced simply. Constitution In lower part bearing box 3 nu being completed section for bolt head storageTo provide 4, supply Tip 14 of lead oil path 10, the box receiving hole 7From center section 16 of box receiving hole 7 inside upper semi- peripheral surface 15Bringing close to main gallery 8, aperture. Box receiving hole 7From center section 16 at the place where it slips in main gallery 8 derivedBecause oilway 10 is communicated to oilway 11, drop of the pistonEven the time there is no void of communication place almost, the oil neutron leakage is lowThe decrease it is possible. In addition, for perpendicular facing of lead oil path 10 the gradient smallEnlarging the fence and the aisle cross section area, lubricity of bearing 20The paulownia be able to process lead oil path 10 at the direction precision where talent improves, is looseru.
