【摘要】 某自动化产线中齿轮传动因齿轮侧隙引发传动误差，齿轮回差产生的冲击力导致无动力小车无规律动作引发打齿或跳齿等故障迫使设备停车，导致设备无法正常运行。以间歇式白酒装盒生产线为研究载体，经结构解析确认其主循环齿轮侧隙集中于动力与翻转机构的齿轮传动啮合副。由于齿轮侧隙存在，齿轮反转产生的冲击力作用到无动力小车，使其不受控向前移动，引发翻转机架滑轨与小车碰撞；翻转机构伺服减速机反转后，翻转滑轨与固定滑轨不能对齐，导致滑块不能顺利通过接缝，甚至撞坏滑块，导致停车。对此，采用磁阻尼减速器耗散啮合冲击动能，以弹性联轴器构建减速机—翻转机架柔性传动拓扑，并引入转角自补偿机构实时消减侧隙误差。经6 500箱/h产能试车验证，该结构优化方案有效解决了齿轮侧隙诱发的停机问题，为通用自动化产线侧隙控制提供了可复用的工程范例。更多还原

【Abstract】 Due to gear backlash, the gear transmission generates transmission errors in an automated production line. The impact force caused by the gear backlash causes the unpowered trolley to act irregularly, and then causes such faults as gear teeth damage or tooth skipping, forcing the equipment to stop and resulting in the equipment unable to operate normally. The intermittent white wine cartoning production line is taken as the research object. Through structural analysis, it is confirmed that the gear backlash in its main circulation system is concentrated in the rack-and-pinion meshing pairs of the power mechanism and the turnover mechanism. Due to the existence of gear backlash, the impact force caused by gear reverse rotation drives the unpowered trolley to move forward uncontrollably, causing collision between the slide rail of the turnover frame and the trolley. When the servo reducer of turnover mechanism reverses, the turnover slide rail cannot be aligned with the fixed slide rail, which leads to the slider unable to pass through the joint smoothly. And even more, it will damage the slider and cause parking.Therefore, a magnetic damping reducer is adopted to dissipate the meshing impact kinetic energy, an elastic coupling is used to construct a flexible transmission topology between the reducer and the turnover frame, and a rotational angle self-compensation mechanism is introduced to eliminate backlash errors in real time. Verified by the production test with a capacity of 6 500 boxes per hour, this structural optimization scheme effectively solves the shutdown problem caused by gear backlash, and provides a reusable engineering example for backlash control in general automated production lines.更多还原
