G2×1250大型减速器是一种中心驱动减速器,具有结构紧凑、传动功率大、效率较高等优点,其结构形式见图1。由于此类减速器精度要求高。材质要求严,其造价也较贵。为了延长减速器的使用寿命,就必须正确使用和及时维护。现结合我厂G2&#... G2×1250大型减速器是一种中心驱动减速器,具有结构紧凑、传动功率大、效率较高等优点,其结构形式见图1。由于此类减速器精度要求高。材质要求严,其造价也较贵。为了延长减速器的使用寿命,就必须正确使用和及时维护。现结合我厂G2×1250减速器调整方法,谈谈这种减速器磨损后的修复问题。机械设备经过一定时期的运转,都会产生不同形式、不同程度的磨损。减速器在正常使用条件下,长期连续运转,就会产生磨损,随着磨损量的增加,减速器的性能下降,甚至已不能满足工作需要。 展开更多

This paper presents a study on the optimum determination of partial transmission ratios of a mechanical drive system using a V-belt and a helical gearbox with second-step double gear-sets in order to get the minimum size of the system. The chosen objective function was the cross section dimension of the system. In the optimization problem, the design equation for pitting resistance of a gear set was investigated and equations on moment equilibrium condition of a mechanic system including a V-belt and a helical gearbox with second-step double gear-sets and their regular resistance condition were analysed. Based on the results of the study, effective formulas for calculation of the partial ratios of the V-belt and a helical gearbox with second-step double gear-sets were proposed. By using explicit models, the partial ratios can be determined accurately and simply. 展开更多

This paper introduces a new study on the optimum calculation of partial transmission ratios of mechanical drive system using a V-belt and two-step bevel helical gearbox for getting minimum size of the system. In the paper, based on moment equilibrium condition of a mechanic system including V-belt and a two-gear-unit of the gearbox, models for optimum calculation of the partial ratios of the V-belt and the gearbox were proposed. As the models are explicit, the partial ratios can be calculated accurately and simply. 展开更多
