①几何方面的精度要求
Geometric accuracy requirements
几何方面的精度要求包括间隙、配合性质、相互位置精度、相对运动精度和接触质量等方面。其中,间隙和配合性质可以统一为尺寸精度要求,主要是指相关零和部件之间的尺寸距离精度。
The geometric precision of the requirements, including the gap, the nature of the coordination, mutual location accuracy, relative motion precision and contact quality, etc.. Among them, the gap and the matching property can be unified for the dimensional accuracy requirements, mainly refers to the correlation between the zero and the components of the size range accuracy.
装配中的相互位置精度包括相关零、部件之间的平行度、垂直度、同轴度及各种跳动等内容。相对运动精度指产品中有相对运动的零、部件之间在相对运动方向和相对速度方向的精度。
In the assembly of the mutual position precision, including zero correlation between components and parallelism, perpendicularity, concentricity and the beating of the content. The relative motion precision of the relative motion of the products in the relative motion of the components in the direction of motion and the relative speed of the direction of accuracy.
运动方向精度多表现为零、部件之间相对运动的平行度和垂直度;相对速度精度也称为传动精度,即要求零、部件之间相对运动时必须保持一定精确程度的传动比。零、部件的直线运动精度或圆周运动精度是相对运动精度的基础。接触精度指接触表面之间的实际接触面积的大小和分布情况。
Motion precision is more performance for the relative motion between the parts and components of parallelism and perpendicularity; relative speed and accuracy is also known as transmission precision, which requires zero between components and relative motion must maintain a certain degree of precision transmission ratio. The accuracy of the linear motion of the parts or the linear motion is the base of the relative motion precision. Contact precision refers to the size and distribution of the actual contact area between the contact surfaces.
②物理方面的精度要求
Physical aspects of accuracy requirements
物理方向的精度要求内容很大,如转速、重量、紧固力、静平衡、动平衡、密封性、摩擦性、振动、噪声和温度等方面,根据具体机器的品种类型和用途,所需要的内容各不相同。
Physical orientation accuracy requirements for the great content, such as speed, weight, fastening force, static balancing, dynamic balancing, sealing, friction, vibration, noise and temperature, according to the varieties of types and uses of the specific machine, need each are not identical.
