    摘要:

    提出用直線齒廓替代內(nèi)齒輪的漸開線齒廓，使?jié)B碳淬火后的內(nèi)齒輪易于成形磨齒。利用齒面接觸分析(TCA)和承載接觸分析(LTCA)技術(shù)，研究分析直廓內(nèi)齒輪與漸開線齒輪嚙合的受力狀態(tài)、齒間載荷分配、傳動誤差。通過臺架試驗，采集漸開線內(nèi)齒輪行星減速器和直廓內(nèi)齒輪行星減速器在不同轉(zhuǎn)速和載荷下的噪聲，進(jìn)行對比分析，研究直廓內(nèi)齒輪傳動的動態(tài)性能。直廓內(nèi)齒輪傳動有“修緣”的特點(diǎn)，承載下的傳動誤差波動比空載小得多。

    Abstract:

    By substituting the straight tooth profile for the involute one, the internal gears with hard tooth face was easily grounded in form grinding. By means of the tooth contact analysis(TCA) technology and loaded tooth contact analysis(LTCA) technology, stress condition, load share between teeth, transmission error were studied, when meshing the internal gear with straight profile with involute external gear. The noise of the planetary reducers with both straight tooth profile internal gear and involute tooth profile was collected respectively by rig experiment. By analysing the collected data, the dynamic transmission performance of internal gear with straight tooth profile was studied. The internal gear with straight tooth profile has the performance of “edge trimming” and a much smaller transmission error variations under loading than no-loading, as a result, it is fully feasible to use the internal gears with straight tooth profile in industry.
