Contact Angle refers to the journal and sliding bearing contact area of the central Angle.Contact Angle is not too big nor too small.Contact Angle is too small will make sliding bearing pressure increases, serious when they make the sliding bearing produces large deformation, accelerate wear, shorten service life.Contact Angle is too big, can affect the formation of oil film, can't get good fluid lubrication.
Experimental research shows that the limit of the sliding bearing contact Angle is 120 °.When the sliding bearing wear and tear to the contact Angle, fluid lubrication will be destroyed.So don't affect the sliding bearing compressive conditions under the premise of the smaller the contact Angle is better.From the theoretical analysis of the friction torque, when the contact Angle is 60 °, minimum friction torque, so, the speed is higher than 500 r/min of sliding bearing, contact Angle 60 °, speed is less than 500 r/min of sliding bearing, contact Angle can be used in a 90 °, 60 ° is used.
The contact point
Shaft neck and the actual situation of the sliding bearing surface contact, available per unit area of the actual contact points.The more contact, more and more even, said sliding bearing scraping the research better, on the other hand, sliding bearing scraping the inquiry is not good.In general the more the more close contact point, research difficulty is large.
