How to use slewing bearing?

Industry occupies a relatively important position, especially today with rapid economic development, when it comes to industry, it must be inseparable from various heavy machinery. This kind of machinery can complete the work, and many machinery are inseparable from one part, that is the slewing bearing.

How to choose slewing bearing according to hardness?

The slewing bearing can be continuously strengthened in terms of hardness. If the slewing bearing is stronger, we will have a great improvement in wear resistance, so that the machine can use the teaching effect better and the product has a more powerful use. efficient. Rolling bearing is a kind of mechanical part. Whether its installation is correct or not directly affects the accuracy, life and performance of the bearing. Therefore, the installation and disassembly of the bearing should adopt the correct method and use the appropriate tools. Inspection of the inner hole of the slewing bearing box, check the roundness and cylindricity of the inner hole, and use the inner hole micrometer to check, the force distribution of the slewing bearing is uneven, resulting in a kind of creep, the raceway load pressure is too large, deformation, affecting the enterprise life. The misalignment of the holes at both ends often occurs. If the axle is tilted after the bearing is installed with a different center, the bearing will be stuck.

What should be paid attention to in the installation of slewing bearing?

Before the slewing ring is installed, the outer surface of the new bearing should be cleaned, most of which are coated with grease. The main function of these greases is to prevent rust and not to lubricate. It should be cleaned before installation and use. Rolling mill bearings are generally sealed with anti-rust oil, which can be cleaned with gasoline or kerosene. The extra-large bearing can be wiped with gasoline or kerosene. The inner hole and other parts are cleaned first with traditional gasoline or kerosene, wiped with dry silk (or dry nylon cloth) cloth, and installed with a small amount of oil.

How to install the slewing bearing correctly?

After cleaning the outer surface of the bearing before the slewing bearing is installed, please pay attention to cleaning the sand of the casting and the bearing parts with burrs and acute angles, so as to avoid residual sand and metal debris during installation inside the bearing, which will affect the assembly quality. Disassembly of tapered bore bearings is always fitted with excess fit. The excess depends on the length of the thrust distance between the bearing and the tapered journal or sleeve. Under the action of thrust, the radial clearance of the bearing decreases, and the size of the thrust determines the fit. During the installation process, the radial clearance of the bearing can be continuously measured until the required radial clearance and ideal pressure matching are achieved.
