要计算汪克尔型转子机轴承的寿命,首先必须确定这些轴承的等值负荷.所谓等值负荷是指理想的不变负荷,在这种负荷下,各轴承的寿命与在周期变化的实际负荷下的寿命是一样的. 要算出等值负荷,首先应计算轴承所受气体力的作用情况.用作这种计算的原始数据是示功图,而且要明确,在汪克尔型转子机中,转子转一圈时(即偏心轴转三圈)完成一个完整的四冲程工作循环.由于转子机有三个工作腔,所以转子转一圈有三个工作冲程,相互间隔120°.
To calculate the life of Wankel rotor bearings, we must first determine the equivalent load of these bearings.The so-called equivalent load refers to the ideal constant load, under this load, the bearing life and the actual changes in the cycle The life expectancy under load is the same.To calculate the equivalent load, first of all should be calculated bearing gas pressure on the role of the original data used for this calculation is the dynamometer, but also to be clear that in the Wankel rotor machine , The rotor rotates one revolution (ie, the eccentric shaft rotates three revolutions) to complete a complete four-stroke working cycle.Because the rotor machine has three working chambers, the rotor rotates three working strokes in one revolution and is separated by 120 ° from each other.
