摘要

为了更准确地研究具有行星传动装置的大功率密度减速器的热功率特性,基于自然散热热功率计算方法和理论,分析了热功率的影响因素,探讨了提高热功率的措施,并以矿用梭车轮边行星减速器为研究对象,在对减速器进行热功率试验的基础上,获得了该减速器总效率和导热系数试验值,并与理论计算值进行了比较分析。结果表明:行星减速器采用6级精度以上的硬齿面齿轮和高精度轴承时,减速器总效率值可取理论计算值上限略降0.01～0.02的值;在实验室空旷的条件下,行星减速器导热系数接近文献推荐上限值,不会因输入功率、输入扭矩等因素而改变。
        In order to study the thermal power characteristics of high power density reducer with planetary transmission more accurately,based on the calculation method and theory of thermal power of natural heat dissipation, the influencing factors of thermal power were analyzed, and the measures to improve thermal power were discussed. Taking the planetary reducer at the wheel edge of shuttle car as the research object, the experimental values of total efficiency and thermal conductivity of the reducer were obtained on the basis of thermal power test of the reducer, and compared with the theoretical calculation values. The results show that: when planetary reducer adopt hard-teeth gears and high-precision bearing with accuracy of more than 6 grades, the theoretical upper limit of the total efficiency of reducer can be slightly reduced by 0.01 ～0.02. Under the condition of open laboratory, the thermal conductivity of planetary reducer is close to the recommended upper limit in literature, and will not be changed by input power, input torque and other factors.
