Antifriction Effect of Micro-Deep Holes for Higher Pair Components
Higher pair contacting components is worn more severely than lower pair contacting components due to the larger contact stress on the contact line. To improve antifriction of higher pair contacting components, the paper proposes a new method by which a large number of micro-deep holes are fabricated on the surface of the contacting component. When higher pair operates, contact stress near the contact line will cause obvious elastic deformation and the volume of the micro-deep holes near the contact line will change, resulting in absorbing oil and squeezing oil. Then an oil film with certain pressure is generated around the micro-deep holes, which will improve the lubrication of components greatly. In addition, a test is carried out and its result shows that the cylindrical roller with micro-deep holes performed better in terms of antifriction than the smooth cylindrical roller.
