Because the sliding bearing no noise, and is generally used for low speed and heavy load conditions, or maintenance and operation of the site maintenance and lubrication difficulties, rolling bearing noise, complex structure, high cost, the structure is not the same
Sliding is tile, the ball is supporting the rotor ah, I suggest you go to the next two definitions, speed and load size, with what bearingsAskWhat if the rolling bearings on the bicycle were replaced by sliding bearings?Chasing the answerIf the modification is not up, ha ha, between the tile and the shaft at rest is at least half of direct contact, to work, to top up oil, have a certain pressure, then to work, but also with a similar pump shaft, ha ha
There is a fundamental difference between plain bearings and rolling bearings.The rolling bearings bear the weight by the ball bearings, and the contact between the friction pairs is unavoidable, and the wear is unavoidable. Just imagine how many tens of tons of rotating shaft, 3000 rpm per minute, if rolling bearings can hold for how long?The static and dynamic parts of the sliding bearing are not in direct contact. When rotating at high speed, the rotating shaft is raised by a high pressure oil film to form a suspension state. So, as long as properly used, sliding bearings can carry dozens of tons of rotating shaft, continuous operation thousands of tens of thousands of hours.
