Analysis work of last brake

Abstract

In this article it is considered the question of effective work last brake, which use for
machinery lifting crane. Show demerits which considerable make worse work both themselves last brake, and work lifting crane. Project calculations not calculation elastic deformation brake of
pulley and appearing while this deformations of last brakes, that changes the square of contact and
considerably worsens the work of brakes.
The definition of the square of interaction of last brakes and brake of pulley gives an
opportunity to define acting contact strains and to evaluate safety and long-termicy of last brakes.
In this work there is achieved the solution for definition of defining radial bends of pulley, what
gives and opportunity to define the deformation of last brakes and real square of their contact to pulley.
