What are the steps of using slewing bearing?

Maybe many old drivers think that the shaking of the upper frame is a normal phenomenon, because the excavator will inevitably have this problem when digging hard, but it is this abnormality that everyone defaults to, which is very likely to cause the slewing bearing to break, unable to work or even It's a safety accident!

So in order to avoid unnecessary failures and accidents, today we will take a look at how to effectively detect and repair the slewing bearing during the construction and maintenance of the excavator!

How to grade slewing bearing?

After the water spray test of the slewing bearing is done, wipe the slewing drive dry, remove the seal of the slewing drive housing and the seal of the slewing bearing, and check whether the tooth meshing part and the slewing bearing channel have water. If water enters, it means that it has not been reached and needs to be improved.

The slewing bearing is used outdoors all day long, and generally it can reach the protection level of IP54, that is, it is dustproof and prevents the intrusion of water splashing from all directions. In order to improve the reliability of the slewing drive and minimize the maintenance frequency, we pursue longer use. Life, through reasonable design and precise coordination, the protection level of the rotary drive of Fuji Transmission has reached IP65, which will bring you a different experience.

How to see the parameters of slewing bearing?

The protection level of the slewing bearing is represented by IP X X, IP is the acronym for INGRESS PROTECTION, and X X is two numbers.

The first number indicates the level of dustproof and foreign object intrusion prevention of the rotary drive (foreign objects, including tools, foreign objects, human fingers, etc., should not come into contact with the internal moving parts of the rotary drive to avoid personal injury or equipment damage).

The second number indicates the waterproof ability of the slewing drive, and the larger the value, the better the waterproof ability of the slewing drive.

The first digit of the degree of protection of the slewing drive (dust rating).

What are the steps of the correct installation method of the slewing bearing?

A, the stiffness of the bearing. Standard slewing bearing and zero-backlash slewing bearing have different requirements on the rigidity of the bearing.

B. Positioning. The inner and outer ring raceways of the slewing bearing have a soft belt, which should be placed on both sides of the main load plane. That is, it is 90 degrees staggered from the main load area. There is a jam or "S" mark on the soft strap.

C. Adjust the gear backlash. When installing a toothed slewing ring, it is important to adjust the gear backlash correctly.

The slewing bearing has been widely used in the large-scale production process. It can be welcomed by large-scale producers for its high production efficiency and low energy consumption.LYXQL slewing bearing Co., Ltd. has worked for many years to meet the need of customers from industrial production, and large-scale commercial production.
