In order to maintain in good condition for as long as cylindrical roller bearings have been the performance of required maintenance, repair, in order to accident prevention in the first place, to ensure reliability of operation, improve productivity, economy. Maintenance best corresponding mechanical operating conditions, operating standards, on a regular basis. The surveillance operation, to supplement or replace the lubricant, the inspection of the regular demolition. Operation, maintenance issues, koyo bearing rotation sound, vibration, temperature, lubricant, state, and so on.
Bearing cleaning: demolition of cylindrical roller bearings under maintenance, the first recorded appearance of the koyo bearings to confirm the amount of lubricant remaining sampling check with the lubricant, wash bearings. As a cleaning agent, ordinary gasoline, kerosene.
Remove the cleaning of the bearing to the points of rough cleaning and fine cleaning, respectively, on the container, first put the bottom of the metal net, bearing no direct contact with the dirt of the container.
Coarse cleaning, so that cylindrical roller bearings rotate with dirt will damage the rolling surface of the bearing, it should be noted.
Coarse cleaning oil, use a brush to remove to grease, adhesive material, and generally clean, and transferred to the sperm washing.
Bearing cracking peeling koyo bearings under the action of the cycle load, the contact surface is very prone to fatigue failure, so in order to improve the service life of bearings, bearing steel must have a high contact fatigue strength.
Hardness is one of the important quality of the cylindrical roller bearing quality, have a direct impact on the contact fatigue strength, wear resistance, elastic limit. Cylindrical roller bearing steel hardness in use is generally to achieve HRC61 ~ 65, koyo bearing contact fatigue strength and wear resistance.
Maintain the aircraft using nylon 46 manufacturing, thereby reducing the sliding friction between the ball and cage. In addition, to eliminate the rotation direction of the concave and convex shape, thereby reducing the mixing loss. In addition, by using the shape of the stress can slow down the assembly to ensure that the assembly performance. Single to keep the shelves loss torque reduced by 30 to 40 percent, cylindrical roller bearings the overall loss of torque has been reduced by 50 to 65 percent. The company speculated that the Prius will be the 10 mode and 15 mode fuel efficiency from the previous 35.5km / L to a 38.0km / L, increased fuel efficiency of about 1 to 2% is obtained through the use of such bearings.
koyo bearing parts in the production process to go through many Road, cold, hot working processes, in order to meet the requirements of high-volume, high efficiency, high-quality, cylindrical roller bearing steel should have a good processing properties. For example, cold, hot formability, machinability, hardenability, etc..
