本文提出了一种简化的数学模型来描述行星齿轮组调制边带的产生机理。该模型包括关键的系统参数，如行星的数量，行星的位置角。以及由齿轮的位置角和齿数限定的行星相位关系。该模型被用来模拟它广泛的齿轮组，以表明它们可以被分为五个不同的组，根据它们的频率和振幅的边带行为。研制了一种特殊的试验行星齿轮装置，并采购了五组中三组的前（）个行星齿轮组。开发了一种方法来证明调制边带的环（内）齿轮径向加速度测量。对于每一种情况下，在各种速度和扭矩条件下的齿圈加速度测量，以证明丰富的边带活动，以及符合模型预测。最后，根据油液的参数研究和实验结果，对油液的流动特性进行了分析。提出了行星齿轮组调制边带的一般规律。(C)2009爱思唯尔有限公司保留所有权利。
In this paper, a simplified mathematical model is proposed to describe the mechanisms leading to modulation sidebands of planetary gear sets. The model includes key system parameters such its number of planets, planet position angles. and planet phasing relationships defined by the position angles and the number of teeth of the gears. The model is used to simulate it wide range of gear sets to show that they can be classified in five distinct groups based oil their sideband behavior in terms of their frequencies and amplitudes. A special experimental planetary gear set-up is developed all(] planetary gear sets front of three of these five groups arc procured. A methodology is developed to demonstrate modulation sidebands from the ring (internal) gear radial acceleration measurements. For each case, sets of ring gear acceleration measurements at various speed and torque conditions are presented to demonstrate rich sideband activity that agrees well with the model predictions. At the end, based oil results of the parametric Studies and experiments. general rules on modulation sidebands of planetary gear sets are proposed. (C) 2009 Elsevier Ltd. All rights reserved.
