FRICTION FACING

摘要

FIELD: machine building. ^ SUBSTANCE: length of facing arc along internal surface and difference of thickness of facing on ends corresponds to ratio: where H2 is thickness of thick end of facing, H1 is thickness of thin end of facing, and L is length of facing arc along internal surface. ^ EFFECT: improved frictional characteristics of friction pair due to optimal correspondence of facing geometry to distribution of forces and pressure in drum brake. ^ 1 dwg
