Rolling bearing is bad? Why a crankshaft is sliding bearing machine?

Usual, social rapidly developed, and the progress of science and technology also will from time to time, most can display is improving little by little! With the progress of the income of people gradually, a lot of families to travel or work lunch, have certain economic ability and stable income in the warp and woof of, have bought their own cars, after all, always drive more people, but few understand car, today small make up again and you share some primary school asked about car, everyone know that the center of a car parts is a machine of this thing, so the stand or fall of a launch machine, then the inside of the resolution to launch machine parts how to sample, recently there are a car owner struggling with the question: why a crankshaft design for sliding bearing, instead of rolling bearing? And below small make up together to discuss this problem! First of all, the first simple introduce you the two bearing, sliding bearing is working under sliding friction bearing, he still has a name called the bearing, the bearing strong sex is high, and don't lock immediately when wear! And in the process of working is very smoothly, and have not too much noise. Rolling bearing sliding bearing is related to the above, just sliding friction into rolling friction, purpose is to reduce friction loss. First small make up feel without rolling bearing, is due to the large level, if say rolling bearing was badly smashed and the immediately begin to show the status of the lock, so in the high-speed shaft of big local, multi-purpose are bearing shell, is not only a machine, is this, and as a big tightening machine are used as the bearing shell! There is a machine on the crankshaft if pack rolling bearing, feel to do not have method, because everybody wants to know, rolling bearing of ball track can't be stitched, if have this phenomenon, it is easy to damage, this is not the cause of the rolling bearing a large level. Associated with sliding bearings rolling bearing, there are many advantages of rolling bearing no, for example, sliding bearing, the smooth oil sufficient conditions, impact resistance, or use, as well as the fine degree of life, noise, small footprint, and so on merits, is rolling bearing does not have, so comprehensive thinking of xuzhou must use sliding bearing!
