| dc.description.abstract | During servo press operation, gear transmission serves as the main drive, however, during the pressing process, the impact significantly damages the gears. Incorrect gear center distance, asynchrony, bearing wear or misalignment of shaft may lead to vibration, and transmission noise or short gear life. As a result, the goal is to improve gear accuracy, strength and longevity, to produce high-quality and high-performance pressing machines. To this end, a servo press gear drive system is constructed, based on the gear design software KISSsys. According to this software, gear strength and transmission error in the servo press gear transmission system are analyzed. Subsequently, gear strength and transmission error are reduced through the gear modification. This in turn leads to reduction of the gearbox vibration. In addition, the dynamic analysis of the servo press gear transmission system is provided by multibody dynamics software ADAMS. The influence of the collision slider and pattern on gear pairs contact forces are investigated. The stress behavior of the gear pairs is analyzed at the lowest dead point of pressing process. Furthermore, an emergency locking force for the drive shaft is derived and the locking force curve is provided. Finally, machine efficiency is improved with constant energy consumption and with a specified required slider translational speed, by the offset of slider modification. | en_US |
