BEARINGS LOAD ON A CIRCULAR SAW MILL DURING CUTTING BEECH WOODS
Keywords:
circular saw mill; cutting mechanism; vibrations.Abstract
The influence of some technological factors on the magnitude of vibrations of the cutting mechanism in a circular saw mill is presented in the study. The cutting mechanism is driven by four V-belts with a “B” section. During operation, vibro-acceleration was measured using specialized measurement equipment described in the methodology. Measurements are made at four points in the radial direction. Two of them are located near the cutting tool (Ax and Ay) of the machine, and the other two (Bx and By) are near the belt pulley. The results of the experiment are presented graphically. The experiments were carried out at a rotation frequency of 1014 min-1. During the experiments, beech trees were cut down. During the research, attention was paid to some technological factors, including the feed speed of the processed material, ranging from 20 m/min to 60 m/min, and the wood thickness, ranging from 80 mm to 240 mm. The study is aimed at improving the reliability and efficiency of a machine as well as ensuring the accuracy and quality of products.
