    摘要:

    利用齒輪嚙合、摩擦學(xué)、傳熱學(xué)、赫茲接觸等理論，研究了嚙合過程中行星齒輪輪齒接觸面的相對(duì)滑動(dòng)速度及齒面摩擦因數(shù)的變化規(guī)律，推導(dǎo)了行星齒輪輪齒齒面接觸應(yīng)力模型。精確計(jì)算了輪齒不同嚙合位置的摩擦熱流密度以及輪齒端面、輪齒齒面等區(qū)域的對(duì)流換熱系數(shù)。建立了輪齒本體溫度場(chǎng)有限元分析模型，獲得了行星齒輪輪齒穩(wěn)態(tài)溫度場(chǎng)。分析了標(biāo)準(zhǔn)齒廓和修形齒廓對(duì)接觸應(yīng)力及溫度場(chǎng)的影響。在穩(wěn)態(tài)熱分析的基礎(chǔ)上，采用有限元法進(jìn)行瞬態(tài)熱分析，得到了嚙合過程中輪齒齒面瞬時(shí)溫度分布。

    Abstract:

    Applying the theories of Hertz contact, tribology, gear engagement and heat transfer, the planetary gear was taken as study object, the variation of sliding velocity and friction coefficient was investigated and the contact stress along the contact path was conducted. Heat transfer coefficient of gear end face and teeth surface and heat flux at different engaging positions were calculated. 3-D finite element models of gear teeth were established to predict stead temperature field. The influence of standard and modified profiles on temperature field and contact pressure was evaluated. Based on the results of stead thermal analysis, distribution of transient temperature field was investigated by using finite element method. 
