The reason why SKF bearings stimulate the sound

Many users have encountered many problems in the use of SKF bearings. Many problems have arisen in the use of SKF bearings. The general mechanical enterprise staff understand the knowledge of SKF bearings, know how to maintain the bearings, and pay attention to the use of the bearing process. Everything is clear, some newcomers don't understand, just know that simply watching the machine running, today we will introduce a phenomenon that the SKF bearing in the machine will be excited, what is the reason?

1. Vibration behavior in applications

In many applications, the stiffness of an SKF bearing is the same as the stiffness of the surrounding structure. Due to this feature, it is possible to reduce the vibration in the application by properly selecting the SKF bearings (including preload and clearance) and their configuration in the application.

2. The waviness of SKF bearing components

In the case of a tight fit between the SKF bearing ring and the SKF bearing housing or the drive shaft, the SKF bearing ring may be deformed in accordance with the shape of the adjacent component. If deformation occurs, vibration may occur during operation. Therefore, it is important to machine the SKF housing and drive shaft to the required tolerances.

3. Excitation caused by the change in the number of loaded rolling elements

When a radial load is applied to a SKF bearing, the number of rolling elements carrying the load changes slightly during operation, ie this causes a shift in the load direction. The resulting vibration is unavoidable, but can be mitigated by axial preloading and applied to all rolling elements (not suitable for cylindrical roller SKF bearings).

4, local damage

Small parts of SKF bearing raceways and rolling elements may be damaged due to handling or installation errors. In operation, rolling through damaged SKF bearing components produces a specific vibration frequency. Vibration frequency analysis identifies damaged SKF bearing components.

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.
