> Industry newsThe limit contact angle of sliding bearing
2017-07-13
The experimental study shows that the limit of the contact angle of the sliding bearing is 120 °. When the sliding bearing wears into this contact angle, the liquid lubrication is destroyed. So no longer affect the sliding bearing under pressure conditions, the contact angle is as small as possible. From
the theoretical analysis of the friction force, when the contact angle
is 60 °, the friction torque is the smallest, so it is suggested that
the sliding bearing with rotational speed higher than 500r / min has a
contact angle of 60 ° and a speed of less than 500r / min, The contact angle can be 90 ° or 60 °.
