For NSK bearings product mass production, high production efficiency, should choose the cleaning equipment and the matching, conveyor belt production, continuously into and out of, and even the use of advanced automatic control technology. Can also set some auxiliary mechanical hand, automatic regulation and counting, cleaning liquid recovery processing, automatic inspection and feedback control system. The workpiece is larger, small quantities of the rotary or fixed cleaning room, choose different angles using the cleaning nozzle to spray cleaning solution from different directions. The cleaning process can be turned over to the workpiece. Set-contained bearing spray washing clean after spray washing, and then use compressed air blowing dryer.
The compressed air nozzle structure. For small workpiece, adhesion of grease serious when, should first dip or spray cleaning. In order to improve the cleaning quality, shorten the cleaning time, cleaning liquid is often used several different, tank sequentially, each tank cleaning grease and the role of different.
Set-contained bearing size and weight of the larger workpieces, is the local cleaning, the partial immersion ultrasonic cleaning tank for cleaning; can also be based on large workpiece shape or local cleaning parts requirements, special structural design, to achieve local cleaning. The shape of the workpiece is too complex or ranging from the size of the hole, groove, ultrasonic cleaning can be used different vibration frequency. Cleaning operations should keep the environment clean, strictly according to the procedure, to ensure and realize safety production is very important.
NSK bearing rings and rolling body has high machining accuracy, in order to ensure the accuracy, life and the main performance of NSK bearings, must adopt the correct methods and steps as well as appropriate tools. Practice has proved, set-contained bearing improper installation often is one of the main reasons for early damage of bearing.
First of all, should be determined according to the installation method of bearing structure type, set-contained bearing size and coordination properties. Pressure method, temperature method and hydraulic method three installation methods of bearing used.
1) NSK bearing installation: installed directly cone bearing the rudiment of shaft neck, can be installed by pressure or heating method, also can use the lock nut installation.
2) cylindrical bore bearing mounting: cylindrical bore bearing mounting, can according to the requirements, select the method of pressure, temperature method and hydraulic method.
