Limit Design of Bearing Contact Angle

The limit of bearing contact angle is 120 °. When the bearing wear to the contact angle, the liquid lubrication will destroy. So do not affect the bearing under the conditions of pressure conditions, contact angle smaller the better. From the theoretical analysis of friction distance, when the contact angle of 60 °, the friction torque is the smallest, it is recommended that the speed is higher than 500r / min bearings, contact angle of 60 °, speed less than 500r / min bearings, contact angle 90 ° or 60 ° may be used.
Bearing surface contact, so the contact surface to maintain a certain oil film, so the design should pay attention to the following questions:
1, to make the oil film can smoothly into the friction surface.
2, oil from the bearing surface into the bearing area.
3, do not make the whole ring oil groove in the middle of the bearing.
4, such as oil tiles, seams at the oil groove.
5, to make oil ring oil fully reliable.
6, filling holes do not be blocked.
7, do not form the oil does not flow area.
8, to prevent the sharp edges and edges cut off the oil film.
