Theoretical study of a pair of "Groom-Saw" to reduce the wear of the grooves in cotton transportation
Abstract
The paper presents the results of theoretical studies of the “groom-saw” pair of the saw gin in order to reduce the wear of the working part of the groom. The gripping ability of the saw teeth is analyzed and it is found that it depends on the angle between the direction of the relative speed and the circumference of the tops of the teeth. It is indicated that having the general coefficient of fiber clogging by abrasive particles and knowing the number of teeth on the saw, as well as the number of revolutions of the saw shaft, it is possible to determine the wear of the groom over time. Also from the analysis of the formula it can be seen that the results of the performed theoretical studies allow us to conclude that using the obtained formulas it is possible to determine the service life of the groom. It was determined that the wear is inversely proportional to the hardness of the material of the working part of the groom and the fiber diameter.
