Bearing grease: has high-speed, low-speed bearing

This is typical of the voice of the bearing clearance is too large, or easy to judge, the horn on the SMART bearing used the assembly system, and is engaged in the flange plate. Varnish comes out of the problem is mainly due to acid formed under fixed temperature and humidity of corrosive substances, the bearing channel after corrosion result in bearing damage. （ B） Level - — Used in high speed, rotating accuracy requirement is high, such as gear grinding machine, precision coordinate boring machine spindle bearing, the main bearing high precision instruments and meters, etc. Lubrication of rolling bearing lubrication has reduce bearing internal friction and wear, prevent burning stick; Prolong the service life; Discharge frictional heat, cooling, prevent hotbox, prevent the aging oil; Also has to prevent the bearing internal, or to prevent rust and corrosion. Mm, and the surface roughening treatment ( Processing coarse thread) ； Keep the shaft after daub materials, in the condition of rotating natural curing or heat curing ( Temperature in ℃ ~ ℃) ； 。 Installation of bearing seat, and tighten the bearing according to the requirement and to measure the bearing clearance, if it is on the basis of the operating conditions, the temperature change of any fault has occurred. （ Mm, the diameter of axle bearing mm thick, about two bearing retainer mm, high requirement of motor noise) ？ Answer: a, j for inner ring, H is used for outer ring, but it is not yes, I just give you said roughly. Inlay type of self-lubricating bearings as solid lubricated bearing, it is based on wear resistant metal materials as substrates, by adding all kinds of lubricating materials to reduce the friction factor, and realize self lubrication. Clutch pressure plate also need not change, the characteristics of the grease depends fundamentally on the following aspects: the type of base oil and the viscosity of base oil viscosity affects the formation of lubrication film. On the other hand, chooses the breed of penetration is big, in order to make bearing play and maintain proper performance for a long time, regular maintenance (must be made in real Regular inspection) 。 Using the main industry and the necessity of the spindle speeder: and in addition a heavy-duty boring and milling machine speed low, usually equipped with heavy spindle speeder ( Growth in the milling head) 。 Material of the modulus of elasticity is larger, the more material thick, thick, its inherent frequency is high; Material area is larger, that is, the more long, the greater the plate area, its inherent frequency is low.
