The object of the research observed is the magnitude of the bending stress on the straight gear that causes pressure on a pair of gears in the bundle crusher. Bunch crusher is a tool that functions to thresh the bunches left in the empty bunches by pressing the bunches between two rollers that rotate in opposite directions. At the end of the roller is a shaft and is installed two straight gears that are connected to each other and when the two straight gears are connected to each other, rotating, the gears experience bending stress. Bending stress is the stress that occurs due to the bending moment. The bending moment occurs because it is influenced by the moment arm that is formed. The study aims to determine the magnitude of the bending stress on the gears in the bundle crusher due to the pressure of a pair of gears. From the results of the study, it was concluded that the magnitude of the bending stress on the upper gear of the bunch crusher when separating the bunches from the bunches of boiled fruit is 8.8 kg/cm2. and the magnitude of the bending moment that occurs on the upper gear of the bundle crusher is 65.934 kg.cm.
