In a humid environment,Condensate can form inside the rolling bearing and cause corrosion,Lead to the shortening of bearing life,Lubricate by careful selection of grease
The selection of bearing grease is directly related to the stable operation of the equipment,In order to better play the best condition of the bearing,The selection of bearing grease must be considered from the following aspects
Use and maintenance of vehicle bearings
Damage types in plain bearings
Bearings are the main components of a locomotive,Especially traction motors、Axle box bearing,Its function plays an important role in safe transportation,When the locomotive is running on line,In case of bearing failure,It will take the entire train out of service,Blocking the main transport line,In particular, passenger trains broke down,The negative impact is even greater,At the same time once the locomotive bearing failure,
Gearbox is one of the important transmission parts of wheel loader,It is responsible for the transmission of speed and torque from the engine to the final transmission system,Change the transmission ratio between the engine and the wheels,
inINAAfter the combination bearing is installed, If not carefully calibrated,Straightening may resultINACombined bearings are subjected to additional loads, Friction and vibration。 These may accelerate fatigue and reduce the service life of bearings, And may damage the life of other machine parts
At the supporting part of the machine,To prevent bearing inner ring with shaft、The outer ring and the outer ring hole slide relative when the machine is running,It has to be simple and effective
Common adjustmentNSKThe method of bearing radial clearance is as follows: 1、Side backlash against cylindrical and oval bearing bush,It can be adjusted by manual grinding and scraping or by repairing and scraping after the turning of the bearing。
Synthetic lubricant(oil、fat)Unlike mineral lubricants,They are prepared by chemical synthesis using chemical raw materials。Domestic since the reform and opening up,Various industries introduce many foreign machinery at the same time,And a variety of synthetic lubricants。Foshan Caden lubrication Technology Co., Ltd. and other synthetic oil development and production units,For the society to provide hundreds of synthetic oil products。
