KOYO linear bearing used with skill in the selection of reasonable method

KOYO bearing fit role is to make the stationary ring and rotating ring, respectively, and installation of bearing parts of the stationary part ( Usually bearing) And rotating parts ( Usually the shaft, Consolidation in together, so as to realize in the condition of rotating relative to the static load and limited movement system the basic task of the system location. In the shaft and bearing, roller bearing requirements in the radial, axial and tangential direction to three directions such as fixed position. Through the positioning of the radial and tangential KOYO bearing ring tight fit the mining of implementation, the axial positioning only in a few cases with tight fit; Generally USES the axial spacing parts, such as end cover and retainer could happen on the axial location clearance range. ( 1) NSK bearing lubricating oil in the main role of engine lubricating oil ( Also known as oil) Mainly can be divided into minerals ( Mimeral油) And synthetic oil ( 合成油) Two categories, which is a higher science and technology of refining, high lubrication function, is nowadays the most cars use of lubricating oil. The main functions of the lubricating oil has the following four: A, no matter how the metal surface is smooth, reduce friction in the case of long-term severe friction wear will appear, and the primary task of lubricating oil supply engine main parts such as piston and cylinder wall, shaft and bearing proper lubrication, reduce the wear between the metal surface. B, reduce the engine temperature, the temperature inside the engine can be as high as 500 ~ 600 degrees Celsius, in the case of high temperature is not only can expand and cause metal resistance, but also produce carbon particles during combustion, result in greater friction heat; Use of lubricating oil is the best cooling method. Is the power of C, sealing function engine comes from the combustion in cylinder of high pressure gas, lubricating oil is in the rift between the cylinder wall, can produce sealing function, ensure that the outbreak of the power can be fully utilized. D, cleaning effect often arise some within the cylinder after combustion process produces carbon or impurities, lubricating oil flow can take away this kind of extremely small obstacles, keep clean in the cylinder. ( 2) Lubricating oil in the engine operation process stops will stay at the bottom of the engine lubricating oil tank, when the engine is started, the oil pump will be the lubricating oil filter after the pump to the bearing parts, and then turn reuse of linear bearing dynamic oil is sent to the main lubrication between the cylinder wall and piston parts, or from the main part of the pipeline pump to other need lubrication; Exist between piston and cylinder wall lubricating oil will be piston ring blow away too much, so in the crack will only appear in the top coat film, and you won't appear too much oil resistance. ( 3) Replace lubricating oil or choose linear bearing lubricating oil additives replacing time without a certain standard, as long as the feet pull out the oil from the engine find remaining oil is located under the line for the change of time. Additives on the market today are general repair metal surface, enhance the function, such as the functions and keep the oil film lubrication endurance, old long car can consider, but due to need a new car 'period', then don't need to use this kind of additive, lest affect normal running in engine parts. Bearing is one of the most important parts in machinery, also can saying is the mechanical joints, and we human beings, without joints, it is no good, if no joints that a paralyzed, and what role? That is of little use, mechanical, too, have no bearing, mechanical cannot use up, so the machine is inseparable from the bearing, can't live out of the bearing, and waste. The using method of linear bearing is very complex, some KOYO bearing is the need to support the use of the general technical personnel to know this knowledge, we generally is certainly don't know, here we come for you to introduce the use of the rolling bearing with and requirements, also familiar with you after bearing dot know basis.
