دراسة تأثير طول ذراع الكرنك على المسافة و السرعة و العجلة للدف في نول النسيج

Abstract EN

The aim of this study is to find out the effect of the length of the connecting rod on the distance, the velocity and the acceleration of the sley of the weaving machine.

Three ranges of values were used in this study.

First when the length of the connecting rod (L) is less than the radius of the crank shaft (L

Second when (L=r) and third when (L

A prototype for the sley mechanism was designed especially for this work.

It was found that when the length of the connecting rod is less than (L

When the length of the connecting rod became greater than the radius of the crank (L > r), the machine could become able to produce fabric.

Eight lengths were used and the effect of the length on the distance, velocity and acceleration of the sley was determined.

The curves of distances, velocities and accelerations obtained through this work would enable the designers to choose the optimum length of the connecting rod required to give maximum velocities and minimum accelerations of the sley of the weaving machine without affecting negatively the weaving processes
