Abstract


In the domain of gear mechanisms, clutch engagement initiates precisely at the moment when the lateral side of the rotating tongue makes contact with the apex of the tooth on the rotated gear. Subsequently, clutch disengagement occurs when the uppermost point of the tooth on the rotating gear meets the lateral surface of the rotated gear. Notably, a decrease in the pressure angle corresponds to an increase in the clutch ratio, albeit with an increase in the minimum number of teeth. In this investigation, three sets of gears with pressure angles of 14.5°, 20°, and 25° were meticulously crafted using KISSsoft for a fertilizer spreader with an input power of 7.5 kW and an input speed of 540 1/min. The study revealed that the gear with a 25° pressure angle performed most effectively for the specified gearbox. These findings underscore the intricate relationship between pressure angle, clutch ratio, and the minimum number of teeth, offering valuable insights into optimal design parameters for enhancing gear system efficiency, as exemplified in the context of a fertilizer spreader application.
