introduction：NSKRolling bearing，Generally by the ferrule、The rolling body and the cage are composed。According to its bearing load direction can be divided into，Radial bearings and thrust bearings。By type of rolling element，Fall intoNSKBall bearing andNSKRoller bearing。It can also be classified according to its shape and specific users。 NSKRolling bearing characteristics，NSKCompared with plain bearings, rolling bearings have the following advantages： Low starting friction，And the difference of sliding control is also small，Standardization has been promoted internationally、normalization，Good interchangeability，It can be used interchangeably between different brands。Refer toNSKBearing standard sumSKFBearing standards You can see that the standards of imported rolling bearings are universal。 The structure around the imported bearing is simplified，Easy maintenance，Inspect。Generally, it can withstand both radial and axial loads。Relatively high、Use under low temperature conditions。For increased rigidity，Even in

introduction：Bearing characteristic： 1、Allow misalignment： Same as spherical roller bearings or self-aligning ball bearings，CARBThe bearing also has self-aligning capability。 2、Allowable radial displacement： Same as cylindrical roller or needle roller bearings，CARB The bearing compensates for the thermal expansion of the shaft。 3、Multiple size series： CARB The bearing has a corresponding spherical roller bearing、Self-aligning ball bearings、Cylindrical roller bearings and needle roller bearings have the same dimensions。 4、Long service life： The special roller profile prevents stress spikes at the roller ends。 5、Low friction： The self-guiding roller keeps friction and friction heat at a low level。 6、Improved wear resistance： SKFThe standard bearings provided are upgradedSKF Explorerbearing。 7、Low noise： For example，CARB Bearings reduce noise and vibration levels in equipment such as paper machines and fans。

introduction：Stainless steel bearings achieve high strength、High precision。Stainless steel bearings are available in acid resistant、Use under special conditions such as water resistance。And because of high mechanical strength、Large load capacity，Widely used in food processing，Medical machinery，Mechanical aspects of medicine，Widely used。Stainless steel bearings are widely used in electric toys、Small motor、Medical device、Household appliance、Spinning reel、Food machinery、furniture、Doors and Windows、Shower room、Anti-rust bearing、Civil chemical pulley，rust-proof、Good flexibility、High speed of revolution、Long life and other characteristics，Used in high-grade skating shoes、Skateboard and other high-end sports equipment,The stainless steel bearings produced are acid-resistant、Alkali resisting、Work under humid and corrosive air conditions。 Stainless steel linear bearings are a linear motion system produced at a low cost，For use with infinite stroke and cylindrical shaft。Due to bearing ball Point contact with the shaft，So th

introduction：skfBearing damage analysis： To look for shaft bearing damage，Can be found in most cases，It can lead to them，Generally speaking，Only one third of the damage caused by fatigue damage of bearings comes from the occurrence of poor lubrication，And the other one-third of pollutants generated from the bearing or improperly handled installation。however，These injury types are not related to the industry bearings are precision parts，So it takes quite a long time to be cautious，Even with high-performance bearings，If used improperly，Nor can it achieve the expected performance effect，And easy to cause bearing damage。 therefore，The use of bearings should pay attention to the following points： first：holdskfBearings and their surroundings are clean，Even tiny invisible dust entering the bearing，Will increase bearing wear，Vibration and noise。 second：Use and install carefully，Let the powerful punch，It is not allowed to hit the bearing directly with the hammer and the pressure of activating the meridian is not allowed

introduction：In general, only a part of the roller of the running bearing bears the load at the same time，The area where this part of the roller is located is called the bearing bearing area。The load borne by the bearing，The size of running clearance will affect the bearing area。If the bearing area is too small，The roller is prone to slip in actual operation。 For wind power gearbox，If the design of the spindle adopts the double bearing support scheme，Then theoretically only torque is transferred to the gearbox。In this case，After a simple force analysis，It is not difficult to find that the load borne by the planetary support bearing is relatively small，Therefore, the bearing bearing area is often relatively small，Rollers tend to slip。Two single-row tapered bearings or two full roller cylindrical bearings are generally used in the design of wind power gear box。 We can improve the bearing area by properly pretightening tapered roller bearings or reducing the clearance of cylindrical roller bearings。Figure 2 s

introduction：Slope and roller type one-way clutches consist basically of cylindrical inner diameter outer rings、An inner ring with a slope and a set of rollers which respectively bear the spring force and are always in close contact with the inner and outer rings are composed。As long as the rotation of one raceway in its direction of motion has an effect on the other，This arrangement essentially ensures the immediacy of overtaking speed and guarantees the ability to drive immediately。The use of this type of one-way clutch can be suitable for overtaking in a variety of environments、Use of indexing and checking。 When used as an overrunning one-way clutch,The ramp roller type one-way clutch will be installed in this manner，Is to use the outer ring as a transcendental component。This is very important for high speed overtaking。In the use of the inner circle override，The centrifugal force acting on the roller will cause the overtaking speed to be limited。 When used as a one-way clutch,Slope roller type one-way c

introduction：Today we mainly talk about hard gear reducer maintenance skills，As everyone knows，Hard gear reducer is widely used，And its material is better，It is made of high strength low carbon alloy steel by carburizing and quenching，High hardness of tooth surface，Then it doesnt need to be maintained？A lot of people have this misconception...
