解析影响动平衡机效果的因素

动平衡机已经在机械行业广泛应用,因为其优势突出,受到广泛好评。不过,也会受到一些因素的干扰。为大家解析影响动平衡机效果的因素。
Dynamic balancing machine has been widely used in the machinery industry, because of its outstanding advantages, has been widely praised. However, there will be some interference factors. Analysis of the impact of dynamic balancing machine.
转子品质不公平衡。因为转子品质不公平衡,转子重心与轴心萌生一个不公正距。当主光轴旋转时,因为失衡品质离心惯性力的效用,主光轴将萌生屈曲变型。轴变型越大,振动也越严重。
Rotor quality imbalance. Because of the imbalance of the rotor quality, the center of gravity of the rotor and the axis of the formation of an injustice. When the axis of rotation, because of the imbalance in the quality of centrifugal force between the utility, will the initiation of buckling deformation. The larger the shaft deformation, the more serious the vibration.
轴线不正。动平衡机机组轴线不正会引动两种方式的振动:弓状回旋。因为转子、转轮几何核心离开正道旋转核心,运行中会萌生横向及纵向振动,直接形成回旋对推力轴承、导轴承均构成要挟,还能增大离心惯性力,两者都使波幅增大。
Axis is not correct. Dynamic balancing machine unit axis is vibration actuating in two ways: arcuate cyclotron. Because the rotor geometry, runner away rotating core core, running in the initiation of lateral and longitudinal vibration, constitutes a threat to direct the formation of cyclotron thrust bearings, guide bearings, but also increase the centrifugal force of inertia, both the amplitude increases.
动平衡机导轴承欠缺。当导轴承松驰、刚性不充足、运行不稳而润滑油不好时,会发生磨擦,引动逆向弓状回旋,即横向振动力。导轴承空隙过小,会把转动轴的振动传给支座和基础,导轴承空隙过大,转动轴振动大。合适的导轴承空隙,才可能同时保障转动轴与支座的振动均在准许范围内。
Guide bearing of dynamic balancing machine. When the guide bearing rigidity is not sufficient, relaxation, unstable running and lubricating oil is not good, friction, when reverse lateral arcuate swing, vibration force. Guide bearing clearance is too small, the vibration of the rotating shaft will be transferred to the bearing and foundation, the bearing clearance is too large, the rotating shaft vibration. The appropriate guide bearing gap, it is possible to ensure that the vibration of the rotating shaft and bearings are within the permitted range.
