圆柱孔轴承通常采用热装，利用过盈配合减小轴承游隙，或者达到预紧的目的。
Cylindrical bore bearing is usually installed with heat, reduce the use of interference fit bearing clearance, or achieving the purpose of pretension.
另外，还采用接触单元对孔轴过盈配合联接组件进行了有限元分析，得到更为精确的强度分布。
Furthermore, the contact finite element was adopted to gain the accurate distribution of strength in the subassembly with the interference between the axle hole and the shaft.
圆轴体同圆盘形孔体的联结，越来越多地采用过盈配合，传递扭转力矩，高速地旋转。
Cylinder shaft body is connected to its hole body more and more by pinch fit so as to transmit torsional moment at high speed of revolution.
