汽车发动机微椭圆轴承配合及其应用

在维修发动机中可选用微椭圆轴承配合，它的主要特点是：可防止因热膨胀而引起的轴承对口向内翘曲，能保持良好的散热条件，能保证良好的润滑性能，能及时地排除微屑与污物。它对保证发动机维修质量，提高发动机的工作可靠性和延长使用寿命起着十分重要的作用。

Micro elliptical bearing fit may be adopted in engine repair and maintenance,ofwhich the main features are: Prevent buckling to inside at the joint of bearing half shells due toheat expansion, maintain good heat dissipation, ensure good lubricating property and get rid ofchips and dirties in time. Therefore it plays an important role in ensuring quality of engine main -tenance and enhancing operating reliability and prolonging service life.
