本文是針對差速器在不同運動條件下的太陽輪、傳動輪及行星齒輪來進行分析與探討,由於差速器主要由傘齒輪組成所以先由兩傘齒輪運轉進行分析以求得較佳傘齒輪設計參數,主要改動的傘齒輪參數有壓力角與背隙跟軸夾角與齒面寬。接著使用繪圖軟體並依照所得的較佳設計參數來進行差速器各零件的繪製及組裝,再來,設計4組轉速參數給予主動輪作為動力,分別為穩定速度與諧波運動的轉速參數,與其經緩衝處理後的運動曲線,再利用繪圖軟體外掛程式來進行動態模擬,觀察太陽輪、傳動輪與行星齒輪在作動時所產生之角加速度的變化並且輸出圖表作探討,得知其運轉時的震動情形,接著將運動分析結果透過來作結構分析,求得應力的數值。此次研究將有助於未來差速器在設計、分析與改良。 在差速器運轉時,其轉速曲線經緩衝處理後對差速器的震動情形較好,運轉較平穩,而轉彎方面,轉彎時的速差是由行星輪的自轉而產生,因此行星輪對於轉彎時的震動影響很大,只要使行星輪轉動穩定,兩輪的震動情形也會減緩。
This article is differential sun gear under the conditions of different sports, driving wheel and planetary gear analysis and discussion of differential bevel gear so the first two bevel gear operation analysis in order to achieve a better umbrellagear design parameters, major changes to the bevel gear the parameters pressure angle backlash with wide angle teeth. Then use graphics software for drawing and assembly of the various parts of the differential and in accordance with the better design parameters, return, Design Group 4 speed parameters given driving wheel as a power, speed parameters were stable speed and harmonic movement, movement after its buffered curve, re-use graphics software plug-ins for the dynamic simulation, observe the sun gear, the change of the angular acceleration of the drive wheel and the planetary gear actuator and output chart to be explored, learned that its operation shock the case, then the movement analysis through structural analysis obtained stress values. The study will contribute to the differential in the design, analysis and improvement. Differential operation, the speed curve by the buffer processed differential vibration of the better, more stable operation, while turning, when cornering speed difference is by the rotation of the planet wheels generated, so the planet wheelsa great influence on the vibration when cornering, the planetary gear rotating stable, two shock scenario will slow.
