【摘要】：鏈傳動作為機械傳動的一種重要傳動形式,在工程上具有廣泛的應用。相關研究人員對鏈傳動性能的研究從未間斷,但是對鏈傳動速度不均勻系數(shù)的研究多局限于理論分析,其實驗測試研究極少。實踐才是檢驗真理的唯一標準。本文就鏈傳動速度不均勻系數(shù)的實驗測試做了研究,并對實驗所得數(shù)據(jù)做了分析。首先從鏈傳動的國內外研究現(xiàn)狀對鏈傳動的研究進行了分析；然后介紹了鏈條與鏈輪,并對鏈條與鏈輪嚙合傳動的運動特性進行了分析；接著對所涉及的鏈傳動速度不均勻系數(shù)測試系統(tǒng)進行了闡釋；最后對鏈傳動速度不均勻系數(shù)實驗測試結果進行了分析和總結。 該實驗測試,主要借助于現(xiàn)代測試方法。通過傳感器將被測信號轉換為適合系統(tǒng)進行處理的電信號,在通過計算機完成信號的檢測、判斷、智能分析等處理功能。并利用NI公司開發(fā)的LabVIEW軟件編寫了一套鏈傳動速度不均勻系數(shù)測試的程序。 鏈傳動速度不均勻系數(shù)實驗測試了： 1.08B單節(jié)距滾子鏈條嚙合08B單節(jié)距滾子鏈鏈輪時,從動輪角速度； 2.208B雙節(jié)距滾子鏈條嚙合08B單節(jié)距滾子鏈鏈輪時,從動輪角速度。 通過理論分析及對實驗數(shù)據(jù)的分析研究得出： 1.主、從動輪齒數(shù)確定后,多次實驗所得從動輪角速度不均勻系數(shù)(δ),介于同相位和最大不同相位時的從動輪速度不均勻系數(shù)(δ1和δ2)之間； 2.從動輪齒數(shù)(z2)變化,主動輪齒數(shù)(z1)固定時,其特定的從動輪速度不均勻系數(shù)(δ0)不變； 3.隨著主動輪齒數(shù)(z1)增大,其從動輪角速度特定不均勻系數(shù)(δ0)減小 4.雙節(jié)距滾子鏈條嚙合于齒數(shù)較多的單節(jié)距滾子鏈鏈輪時,其傳動性能較嚙合于齒數(shù)較少的單節(jié)距滾子鏈鏈輪時為好。
[Abstract]:As an important form of mechanical transmission, chain transmission is widely used in engineering. The research of chain transmission performance has never been interrupted, but the research on the non-uniform coefficient of chain transmission speed is limited to the theoretical analysis, and the experimental research is very few. Practice is the only criterion of truth. In this paper, the experimental test of the inhomogeneous coefficient of chain speed is studied, and the experimental data are analyzed. Firstly, the research on chain transmission is analyzed from the current research situation at home and abroad, then the chain and sprocket are introduced, and the kinematic characteristics of chain and sprocket meshing transmission are analyzed. Then the testing system of chain speed inhomogeneity coefficient is explained. Finally, the experimental test results of chain transmission speed inhomogeneity coefficient are analyzed and summarized. This experimental test, mainly by means of modern test methods. The measured signal is converted into an electrical signal suitable for processing by the sensor, and the signal detection, judgment, intelligent analysis and other processing functions are completed by the computer. Using the LabVIEW software developed by NI Company, a program for testing the uneven coefficient of chain transmission speed is developed. The non-uniform coefficient of chain transmission speed is tested experimentally. When the 1.08B single-pitch roller chain meshes 08B single-pitch roller chain sprocket, the angular velocity from the moving-wheel; 2.208B double pitch roller chain meshing 08B single pitch roller chain sprocket, angular velocity from the motor wheel. Through theoretical analysis and experimental data analysis, it is concluded that: 1. In the main, after the number of teeth is determined, the angular velocity inhomogeneity coefficient (未 _ (1) and 未 _ (2) of the driven wheel is obtained from many experiments. The coefficient is between the velocity inhomogeneity coefficient (未 _ 1) and the velocity coefficient (未 _ 2) at the same phase and the maximum different phase. 2. When the number of teeth of active gear is fixed, the inhomogeneity coefficient (未 _ 0) of the specific velocity of driven wheel is not changed when the number of teeth is changed from the number of teeth to the number of teeth of driving wheel, and the number of teeth of active gear is fixed. 3. The specific inhomogeneous coefficient (未 0) of the angular velocity decreases with the increase of the number of teeth of the active gear. 4. When the double pitch roller chain meshes with the single pitch roller chain sprocket with more teeth, its transmission performance is better than that of the single pitch roller chain sprocket with less teeth.
