| 摘要: | 伺服壓力機運行時，主要以齒輪傳動為主，然而在衝壓過程中，對齒輪的衝擊損傷頗大。錯誤的齒輪中心距、不同步、軸承磨損或軸未對準可能會導致振動、產生傳動噪音或使齒輪壽命縮短。因此，為了生產高品質及高性能的衝壓設備，應該以提高齒輪精度、強度和壽命為目標。為此，在機械設計軟體KISSsys的基礎上，建構了伺服衝床之齒輪傳動系統分析模型。該軟體對伺服壓力機齒輪傳動系統中的齒輪強度和傳動誤差進行了分析。透過輪齒修整可降低齒輪強度和傳動誤差，進而減少齒輪箱的振動。此外，多體動力學軟體ADAMS還進行了伺服壓力機齒輪傳動系統的動力學分析，研究了碰撞及滑動接觸對齒輪副接觸力的影響，分析了齒輪對接觸力在衝壓過程中死點處的應力結果。此外，導出驅動軸的緊急鎖定力並提供鎖定力曲線。最後，通過偏置距的修正，在輸入功率不變及指定衝頭平移速度下，以模擬證實提高了衝床的工作效率。;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. |
