Where is the difference between the rolling bearing and sliding bearing? Bearing tell you

Bearing is the most cannot little parts in the mechanical equipment, has strong point the effect of rotation. Based on features of friction in the bearings, can be divided into two kinds of bearings, Rolling bearing) And ( Sliding bearing) 。 Two types of bearing structure are all the features, characteristics and has all the advantages and disadvantages, used to be able to contact the actual application to consider. The characteristics of rolling bearing and sliding bearing is ( 1) Structure and movement mode compared with rolling bearing and sliding bearing is the most significant each have two kinds of bearing roller rolling bearing rotation is to rely on to support roller drive shaft, thus the location of the touch is a point, rolling body, the more the greater the touch point. The design of the sliding bearing is not rolling body, by smooth surface to the drive shaft. The structure of the two kinds of bearing different decided to the operation of the two kinds of bearing method is completely different. （ 2) Bearing capacity than the general seems to be the strength of the sliding bearing with a total area of the bearing capacity is higher than rolling bearing, and rolling bearing under impact load ability is not high, but completely liquid lubricated bearing lubrication oil has the effect of the buffer, able to bear the relatively large impact load. When bearing high speed, under the condition of rolling bearings of rolling body centripetal force increases, the need to reduce the bearing capacity. （ 3) Friction resistance and the friction than in your work situation, frictional resistance is much low sliding bearings of rolling bearings, and the values are relatively stable. And the sliding bearing lubrication is very vulnerable to the dangers of external factors causing friction system change category is very large. （ 4) Output power damage than for rolling bearing friction resistance is small, so the damage in work output power is not big, more to not completely liquid lubricated bearing, at that time if damage output power under the condition of poor lubrication and installation will soar. ( 5) Other application level when compared with rolling bearing maintenance dosage of oil and lubricant is relatively small, under the condition of high speed rotating amount is relatively large, cleanliness regulations of lubricating oil is higher, and sealing, but bearing the conversion is convenient, need not repair the motor shaft. And sliding bearing, except incomplete liquid lubricated bearing lubricant is generally applied liquid or gas, the dosage of the lubricant is relatively large, the regulation of product cleanliness is higher also, bearing piston pin must often moved around, sometimes I repair the motor shaft. The above is the content of the author to share today, want to learn more bearing small knowledge, pay attention to the bearing's official website.
