THE RELAXATION OF SPRINGS ON BELT-DRIVE SYSTEMS ON COMBINE HARVESTERS

Popis výsledku v původním jazyce

The article discusses the problem with the use of compression springs on belt-driven tensioning components implemented on combine harvesters. Incorrect use of setting on the belt-driven tensioning component can cause the tension spring to be relaxed thereby causing a high temperature and lowering the effectiveness and lifespan of the entire drive system. The study concentrates on the main belt-drive system of the threshing system on the combine harvester using a quasi-static load on the compression springs. Tension strength on compression springs compressed at a length of 105 mm was used on a machine over a period of three, five, six, nine, and ten years. The reference value used to determine the drop of the tension force is a set of new springs with the average tension force of 1,445.8 N and a standard deviation of 16.4 N. The measurement results showed a 4 % decrease of the tension force when the machine was used for three years, 9.3 % (five years), 9.8 % (six years), 15.9 % (nine ye
