Bearing corrosion solution

To prevent rust, we must first improve the anticorrosive ability of bearing itself. Bearing material is bearing steel, anti-rust treatment methods commonly used in internal coating anticorrosive oil bearing, bearing after antirust processing, by electric grease. But if the anti-rust oil besmear too thick, can lead to the lubrication performance degradation. Although attention to improve the rust resistance of the grease, have certain effect, but still the most effective way to change the insulating varnish. Due to the insulating varnish will produce harmful acid gases, of course, will cause bearing rust, specific solutions: 1) As far as possible using solvent-free paint or excluding volatile acid hydrolysis resistance, good paint of paint. 2) If possible, use do not contain chemical dipping paint, such as epoxy urine anhui base or modified epoxy impregnating varnish. 3) Using melamine alkyd varnish, should adjust the curing temperature and curing time, curing temperature is slightly higher than 130 ℃, Such as 135 ℃) And curing time is greater than 3 h advisable, and must be strictly implemented process, especially in high temperature and wet season, because from the perspective of the concept of rust, paint factory in the sample although rules for paint drying ( Curing) Time, is not necessarily sufficient, because different motor with specific inner shape. 4) As far as possible choose mineral oil bearing grease. 5) Electric grease injection on their own, in order to avoid water vapor in the air and dust into the bearings, noise and may cause corrosion factors, grease container should be sealed, even so should note fat, fat injection process should be kept clean and dry. Grease injection rate as stipulated in the standard. 6) Choose a microporous plastic film packaging, make motor before have certain permeability. Because plastic film packing, paint will stay within the bearing gas, moisture condensation.
