Sliding bearing wear to the contact angle, the liquid lubricant is necessary to destroy the

When the slide bearing wear to the contact angle, the liquid lubricant should damage. Therefore, do not affect the conditions set bearing pressure, the contact angle the smaller the better. From the frictional mcb circuit breaker the theoretical analysis, when the contact angle is 60 °, the friction torque minimum, it is recommended that the speed is mcb circuit breaker 500r/min sliding bearing, the contact angle using the 60 °, 500r/min speed is lower than a sliding bearing, the contact angle can be used 90 °, may also be used 60 °.
Because of its Electric transformer torque so widely used in engineering construction waterproofing sub-projects, sub-projects in water-base construction, surface contact angle with the wall angle R is usually made ​​of shape in order to achieve the role of water.
