    The speed- fluctuation of the loom crank shaft has much effect on the study of loom action and dynamic analysis. Without consideration of the fluctuation of speed, the result of any study will deviate from the actual condition to a great extent. Therefore, the calculation of the speed of the loom crank shaft and the determination of the moment of inertia of the "two shafts" (the crank shaft and the cam shaft with all the rotating parts mounted on them) is of important significance...

    The speed- fluctuation of the loom crank shaft has much effect on the study of loom action and dynamic analysis. Without consideration of the fluctuation of speed, the result of any study will deviate from the actual condition to a great extent. Therefore, the calculation of the speed of the loom crank shaft and the determination of the moment of inertia of the "two shafts" (the crank shaft and the cam shaft with all the rotating parts mounted on them) is of important significance to the loom designers and research workers. This paper is first given a brief statement of the significance of the speedfluctuation of the loom crank shaft and the balance of energy. Then it suggests a method of calculating the speed-fluctuation of the loom crank shaft and determining the magnitude of the moment of inertia of the "two shafts". The main principles adopted here are: first, the use of an equivalent moment of inertia of the "two shafts" and the beating mechanism; second, broadening the sense of the work done by the resisting torque of the loom; third, assuming that the consumed energy of the picking mechanism is not directly related to the speed-fluctuation of the crank shaft. Thus, the mutual effect of the balance of energy and the fluctuation of speed which existed in Prof. A. P. Maleshef's method is now eliminated. Therefore, it is possible to derive two equations, (11) and (14), for Calculating.the speed-fluctuation of the loom crank shaft and the moment of inertia of the "two shafts" directly, instead of the cut and try method given by Prof. A. P. Maleshef. Finally, two examples are given to justify that the suggested method is practically accurate.

    織机迴轉不均勻性对研究织机的运动学与动力学有很大的影响。不考虑迴轉不均匀性,对織机进行任何研究都是脫离实际的。因此研究织机迴轉不均匀性和“两軸”轉动惯量的計算,对設計者和研究者而言都是有重要意义的。本文首先对織机迴轉不均勻性及能量平衡作了簡要的說明。然后提出一个計算方法,它的主要論点是:采用了相当转动慣量和推广了阻力功的意义,并且假設投梭机構所消耗的能量与迴转不均勻性无直接影响。这样就可以消除能量平衡与迴轉不均勻性相互的影响,从而导出了兩个公式(11)与(14)用以直接地計算迴轉不均匀性和兩軸轉动慣量,不必采用馬雷舍夫教授的逐次漸近法。最后用兩个实例計算証实了这个計算方法在实用上是正确的。

(4) The relationship between the mass of the lay and speed fluctuation of loom crank shaft. (5) The effect of decrease of the mass of the lay on loom vibrations. Finally, it is pointed out that for Type 1511...

    Various problems concerning the mass of the lay calculation are discussed as follows: (1) The fundamental equations to calculate the moment of inertia and the mass of the lay. (2) The maximum beat-up force calculation (Pmax). (3) Determination of the minimum value of the moment of inertia of the lay. (4) The relationship between the mass of the lay and speed fluctuation of loom crank shaft. (5) The effect of decrease of the mass of the lay on loom vibrations. Finally, it is pointed out that for Type 1511 Loom to decrease the moment of inertia of the lay to 1/2 of the existing value is suitable.

    本文研究了有关計算筘座質量的如下若干問題: 1.筘座轉动慣量及筘座質量計算的基本公式; 2.最大打緯力Pmax的計算; 3.筘座最小轉动慣量的决定; 4.筘座質量及織帆兩軸迴轉不均勻性之間的关系; 5.减輕筘座質量对織机振动的影响。最后指出1511型織机上筘座的轉动慣量减小一半是合适的。

    The reliability of nodular-iron crank shaft castings manufactured form pig iron with an average phosphorous content of 0.13% is discussed. By means of isothermal quenching, the mechanical properties of the crank shaft of diesel-engine 195 are found to meet all technical requirements and neither fracture nor tearing has so far been detected after over 1500 hours' field test. The wear resistance of the shafts is a little better than that of the shafts made from Bench low-phosphorous iron....
