Large metal noise abnormal load correction combined with, study on bearing clearance, adjust the preload, amended casing abutment
Install bad, shell processing accuracy of the shaft to improve precision, installation method.
Inadequate lubricant, is not appropriate. Additional lubricants and choose the right lubricant
Contact rotating parts to modify curved path of contact parts
Normal tone scroll surface indentation, rust, due to foreign body injuries replacement of bearings, wash the parts, improved sealing device, use clean lubricant
(Steel after carburizing) replacement of surface deformation, attention to their use.
Raceway surface fracture replacement
Study on abnormal sound clearance is too large tie and bearing clearance, modify the amount of preload
Foreign bodies penetrated study on replacement of bearings, wash the parts, improved sealing device, use clean lubricant
Ball injury, break replacement
Cause of the cylindrical roller bearing early wear is multifaceted, sum up the following five aspects.
Unreasonable includes errors in design and calculation of structural design of ①; structural design, size, precision, inappropriate bearing alloys, coating materials, as well as backing material, bearing lubricant improper.
② flaw in production process, processing quality is not high include sintering, casting bearing alloy, double-rolled and coated sheet metal machining process behind compound plating process is defective, and so on, cause the cylindrical roller bearings alloy microstructure, composition, performance, and sizing accuracy does not meet the design requirements.
③ negative Assembly process including Assembly process backward, uncivil, not strict production management; after Assembly did not meet the original design of assemble accuracy requirements. Diesel engine factory is not scientific, improper break-in can lead to early damage of Bush.
④ use and poor maintenance including unsound practices, lax maintenance system, using negligence, excessive overload, man-made or accidental conditions such as speeding and poor conditions.
⑤ other part involved failure of lubricating oil, filter improper or failed, housings or axle is too large deformations, damage, vibrations will cause bearing damage.
