About roller bearing Assembly Dimension Chain Definition
Closed loop assembly dimension chain is often imported bearing assembly precision or technical requirements. Because this requirement is met through the parts, components assembled before the final form and guaranteed, size, or position is a result of the relationship.
From the design point of view, is the lead assembly precision bearings and forming the China roller bearing for assembly dimension chain, which also determines the design and manufacture of precision parts basis. Identify with the precision of parts and the corresponding relevant dimensions, and draw the corresponding dimension chain diagram. And the accuracy of the relevant parts related parts called, the corresponding relevant dimensions, called correlation dimension is an integral assembly dimension chain ring.
The establishment of assembly dimension chain is the first step in solving the problem assembly accuracy, only when creating assembly dimension chain is correct, it makes sense to solve dimensional chain. Therefore, in the assembly dimension chain, this step is very important.

it is possible to reduce the weight of the car battery and extend farther.
NTN developed lubricants and adoption of new technologies can be sealed bearing retainer 50% decrease resistanceBack]NTN (NTN) using a newly developed lubricant and cage, developed a resistance to rotation compared to the previous product reduced by 50% or more sealed deep groove ball roller bearing. For the EV (electric vehicle) motor, can reduce mechanical losses and improve efficiency, it is possible to reduce the weight of the car battery and extend farther.
For supporting the rotor is sealed deep-groove ball bearing due to the light load, the circumstances under high-speed rotation, so the rotational resistance from most of the lubricant oil sealed in the internal stirring resistance. NTN To reduce this resistance, constituting the lubricating base oil, thickener and additives these three elements, the implementation of a lower viscosity base oil, and the fine structure of the improved hand jack. Base oils combined thickener has prompted function, therefore, will enhance the micronized base oil retaining capacity of the state, thereby reducing the amount of thickener used.
The noise when driving (quietness), the motor to ensure the original performance equal or lubricant. Further, with the use of the best ratio of lubricating oil additives, oxidation inhibited lubricant caused by the aging, to achieve the same or higher with the previous product life.
In addition to the development of oil, but also improves the rolling element cage and cage pocket shape of the contact hole is suppressed too much lubricating rolling surface of a bearing case.

Bearing basic technical knowledge
Bearing joints: the sliding contact surface of the spherical, mainly applicable to swing movement, tilting movement and rotation of spherical plain bearings.
Bearings: a set of bearing two or more simultaneously by said bearing structure combination of rolling bearings. Such as needle roller and thrust cylindrical roller bearings, needle roller and thrust ball bearings, needle roller and angular contact ball bearings.
Other Bearings: In addition to the above other than the structure of the rolling bearing.
2, the bearing parts
Bearing parts: one consisting of the parts bearing, but does not include all the accessories.
Bearing rings: one or several raceway bearing to the heart of the annular parts.
Bearing washer: with one or several of the thrust bearing raceway ring parts.
Flat ring: a detachable substantially flat washer, use it as an inner or outer part of the radial cylindrical roller bearing outer or inner ring of a wall.
Thrust collar (detachable): a separable with "L" shaped cross-section ring, with the outer part of a radial cylindrical roller bearing inner ring of a wall.
In the ring: having two or more rows of rollers of a roller bearing inner ring separable used to isolate two rollers and guide rollers.
Snap ring: single port having a constant cross-section ring, mounted in a ring ditch, a roller bearing in the housing or shaft axial position.
Lock ring: single port with constant cross-section ring, mounted as a ring in a ring ditch rollers or cage will remain in the bearing.
Spacer: the annular parts, for the two bearing rings or bearing washer, or between the two halves or between the bearing rings between the two halves of the bearing washer, so that they are maintained between the axial distance required.
Seals: formed by one or several parts of the ring cap fixed to the bearing and a ferrule or the gasket ring or gasket in contact with another or to form a narrow gap labyrinth, prevent oil leakage and foreign matter.
Cover: is a ring cover, usually a thin metal plate stamping, a ring fixed to the bearing or washer and extending towards the other ring or gasket, cover bearing internal space, but not with another ring or gasket contacts

Oil spill caused by the bearing ring hair treatment
Bearing due to frequent use, and oil will reduce bearing life, then how do we clear bearing on the oil it? Here to teach you an easy method of clearing the oil on the bearings.
Soft dry oil or rust paste hardened bearing should immersed in 100 ℃ ~ 200 ℃ hot oil, use pliers bearings, bearings with a hair brush oil on a clean. Soft dry oil or rust cream is heated to 100 ℃ ~ 200 ℃ to melt easily washed from the cracks in the bearing out. Sometimes just the bearing in the oil repeatedly shaking. Oil will be flowing away from the gap.
In cleaning bearings, spherical bearings to the heart, it should put the ball, bead frame, the inner from the outer lateral transfer out and then immersed in hot oil, the short cylindrical roller bearing roller cleaning when they should, bead frame, inner and outer disengage.
(A) the bearing raceway raceway sound and control the sound is running when the bearing, the rolling body raceway rolling issued a slippery continuous sound, all bearing the unique occur basic sound . Sound that is generally bearing raceway sound with other sounds. Ball bearing raceway sound is irregular frequencies above 1000Hz, its main frequency does not change with the speed, but the total sound pressure level increases with the speed acceleration. Raceway sound big INA bearings, the roller with the sound pressure level decreases with increasing viscosity; while the sound of a small roller bearings, and its level increased in viscosity to about 20mm2 / s or more, by reducing the to be increased. Greater rigidity of bearing raceway total sound pressure level is lower. If the radial clearance is too small, the total sound pressure level raceway and the main frequency will decrease as the radial clearance increases dramatically. Control raceway sound methods are: selection of low-noise bearings that waviness small bearings, judicious selection of the conditions of use. Raceway sound often affect the entire mechanical noise reduction raceway sound can reduce the overall mechanical noise.
(2) the impact of rolling sound and control models of ball bearings or larger cylindrical roller bearings in pure radial load low speed, the centrifugal force due to rolling body is small, in a non-load zone of rolling element will Shock cage or raceway and noisy. However, as the speed increased, the sound will disappear. Impact on the rolling sound control methods are: appropriate to reduce the radial clearance, the use of reasonable structure supple material of the bearing cage.
(3) bearing jarring sound and control jarring sound is a cylindrical roller bearings on all occasions that may occur harsh sound of metal friction occurs mostly in grease lubricated bearings in larger models, and in the base oil properties more susceptible to deterioration of grease, oil lubrication in almost no time. In addition, more prone to winter, when subjected to pure radial load, radial clearance prone to big occasions, and with models of different sizes, at a particular speed range prone to both occur consecutively will appear intermittently. Outer ring raceway take special processing methods to prevent the emergence of creaking, if necessary, use this bearing, or appropriate to reduce the radial clearance, use grease with excellent performance and increasing the rigidity of the bearing mating parts .
