The importance of maintenance and maintenance of KOYO bearings

The maintenance and maintenance of KOYO bearings is very important. It is related to its service life, work efficiency, and how to maintain and maintain the KOYO bearings used by them. It benefits a lot. From the work aspect, it brings you high production efficiency and production. For quality products, economically, several maintenance can extend your life and save you money on re-purchasing.

A retainer structure of a ball bearing, which is an annular structure, can be arranged at intervals of a plurality of balls, and the KOYO bearing performs the desired rolling in the ball bearing, the retainer includes a plurality of spacers, and the spacer is formed with Contacting the inclined surface, the contact inclined surface and the inner end surface form a wall thickness angle of 60-85 degrees; for this geometric shape, the ball can be effectively prevented from forming a concentrated force during the high-speed rolling of the retainer, and the surface of the ball is scraped off. Lubricating body can be applied to the surface of the ball evenly, so that the ball bearing and its ball have better lubrication conditions.

The pump that is newly put into use must be replaced with grease (oil) after 100 hours of operation, and then replaced once every 500 hours. Grease-lubricated flow KOYO bearings, after 1500 hours of operation, the grease should be replaced, the amount of oil added should not be too much or too little, KOYO bearings because of too much or too little grease will cause KOYO bearings to heat, the amount of fuel is generally It is advisable to master 1/2 to 2/3 of the KOYO bearing chamber volume. For KOYO bearings lubricated with lubricating oil, the amount of oil should be added to the specified position. Containers containing lubricating oil or grease should be clean and should be sealed properly. There should be no dust or iron filings to avoid damage to KOYO bearings. Motor bearings generally use sodium-based grease, which is characterized by high temperature resistance (125 ° C), but is easy to dissolve in water, so it can not be used for lubrication of pump KOYO bearings.

FAG bearing grease injection method

There are four main methods for injecting grease into FAG bearings. They are the grease cup method, the smear method, the grease gun method, and the concentrated fat method.

First: fat cup method

Open the small hole next to the FAG bearing to the grease cup, and the grease in the cup is continuously replenished to the FAG bearing. For high-speed FAG bearings, a grease-reducing valve should be installed to remove excess grease from the FAG bearing by the centrifugal force when the FAG bearing rotates to reduce the friction of the FAG bearing and the temperature rise caused by high-speed rotation.

Second: smear

Use special tools when applying, and do not use bare hands. The required amount of fat is required to meet the above requirements, and the grease should be filled with all the surfaces of the FAG bearing that require lubrication. After the grease has been used for a certain period of time, it is necessary to change the fat or make up the fat.

Third: fat gun method

The grease is used to press the grease into the FAG bearing through the grease hole through pressure. This method is often used to replenish fat.

Fourth: Concentration to the lipid method

The pump is used to transport the grease to the parts of each FAG bearing through the pipeline. The flow path of the newly added grease should be able to squeeze out the old grease, so that the new grease can be filled into the lubrication points.
