SHOCK-PROOFED AXIAL BEARING FOR PILOT SUPPORT

摘要

FIELD: mechanical engineering. SUBSTANCE: bearing member of shock-proofed axial bearing for pivot support is manufactured in the form of barrel with thin flat elastic bottom and axial bar. axial bar is located inside barrel and bulges out beyond its open end face. Bearing surface of member is manufactured in the form of crater. Shape of crater may have shape of cone conjugated with cylinder for more sensitive devices to reduce friction moment in bearings if axis is in horizontal position. Point of conjugation of cone with cylinder has chamber with radius equal to that of pounding of pivot. Bottom thickness may be 2-4 times smaller than diameter of bar and diameter of bar is 1.5-2.0 times smaller than length of bar. Bearing member may be manufactured from temperature-sensitive material with filling agent containing 20.0 % of MOS2 or 15.0 % of glass fiber. EFFECT: enhanced operational characteristics of bearing. 3 cl, 2 dwgi
