Title:Кръгли ексцентрици с постоянна сила на затягане
Author:Недялков, Александър Стоянов; Nedialkov, Alexander Stoyanov; Йорданов, Георги Добрев; Jordanov, George DobrevDate:1995Abstract:It is well known that the round excentrics do not provide a constant tightening force of their working profile. This fact is due to the vari¬ance of the slop angle on different points of the profile.
In the paper a design of a device ensuring constant tightening force of the working profile of the round excentrice is described. It compensates ...Library:
