本文提出了刮板输送机减速器传动参数的优化设计的指导思想,建立了减速器传动参数优化设计的数学模型,并采用约束非线性离散优化方法进行优化。该数学模型以I轴伞齿轮的承载能力做为优化目标,同时,在保证刮板输送机减速器散热条件和三级齿轮的承载能力相互均衡的条件下,使减速器Ⅱ、Ⅲ级传动的中心距之和最合理。本文所编制的优化设计程序对所有型号的减速器都适用,用本程序对多种国产减速器重新设计,结果表明,在减速器体积不变的情况下,其整体承载能力可提高20～55%,减速器的其它性能也大为提高。
In this paper, the guiding principle of optimal design of transmission parameters of scraper conveyor reducer is put forward. The mathematical model of optimal design of transmission parameters of reducer is established and optimized by constrained nonlinear discrete optimization method. The mathematical model of I-axis bevel gear carrying capacity as an optimization goal, at the same time, to ensure that the scraper conveyor speed reducer cooling conditions and the bearing capacity of three gear equalization conditions, the reducer Ⅱ, Ⅲ-level transmission The center distance and the most reasonable. The optimized design program compiled in this paper is applicable to all models of gearboxes. With this program, a variety of domestic gearboxes are redesigned. The results show that the overall carrying capacity of the gearboxes can be increased by 20-55 %, Other reducer performance is greatly improved.
