【摘要】：刨鏈預(yù)緊力是影響刨煤機(jī)運行的重要工況參數(shù)。分析刨鏈預(yù)緊力對刨煤機(jī)運行的影響,得到了刨削時和空行程時刨鏈預(yù)緊力及預(yù)緊力選取范圍的計算公式�？紤]刨鏈繞經(jīng)鏈輪時曲線阻力的影響,采用逐點張力法得出刨鏈總牽引力的計算公式。定量分析了預(yù)緊力變化對刨鏈總牽引力及刨煤機(jī)能耗的影響,結(jié)果表明:預(yù)緊力增加,刨煤機(jī)能耗明顯增大。并通過自制的刨煤機(jī)試驗臺,對空行程時不同預(yù)緊力條件下的刨煤機(jī)功率進(jìn)行測試,試驗結(jié)果更加說明了預(yù)緊力對能耗的顯著影響。為合理選取刨鏈預(yù)緊力、刨煤機(jī)設(shè)計和使用中的節(jié)能降耗提供理論基礎(chǔ)。
[Abstract]:The pretightening force of planer chain is an important working condition parameter that affects the operation of coal planer. The influence of pretightening force of planer chain on the operation of planer is analyzed, and the formulas for calculating the pretightening force of planing chain and the selection range of pretightening force during planing and space stroke are obtained. Considering the influence of the curve resistance of the planing chain around the sprocket, the formula for calculating the total traction force of the planing chain is obtained by using the point-by-point tension method. The influence of the change of pretightening force on the total traction force of planer chain and the energy consumption of planer is analyzed quantitatively. The results show that the energy consumption of planer increases obviously with the increase of pretightening force. Through the self-made planer test bench, the power of the planer under different pretightening forces during the empty stroke is measured, and the test results show that the pretightening force has a significant influence on the energy consumption. It provides a theoretical basis for reasonable selection of pretightening force of planer chain and energy saving and consumption reduction in the design and use of planer.
