What is the meaning of turntable bearing?

The material of the turntable bearing is made of oil-resistant nitrile rubber. The codes of the ferrule material and the supply state of the blank are as specified in the table. In the table, "T" means that the ring blank is supplied in a quenched and tempered state, and "Z" means that the ring blank is supplied in a normalized state.

What are the materials of the turntable bearing?

The cage for turntable bearing has integral, segmented, isolated block and other structural forms. The integral and segmented cages are made of 20-gauge steel or ZL102 cast aluminum alloy. The spacer block type is made of polyamide 1010 resin, ZL102 cast aluminum alloy, etc. With the continuous development of the material industry, nylon GRPA66.25 has also been popularized and applied in the design of segmented cages.

The material of the turntable bearing seal is made of oil-resistant nitrile rubber. The codes of the ferrule material and the supply state of the blank are as specified in the table. In the table, "T" means that the ring blank is supplied in a quenched and tempered state, and "Z" means that the ring blank is supplied in a normalized state.

What causes the abnormal noise of the turntable bearing of the coal mine roadheader, and how to troubleshoot it?

First of all, it needs to be clear that when the turntable bearing just leaves the factory, when the turntable bearing is idling, there will be a sound of steel balls rolling evenly, which is a normal sound; if it is installed soon, it does not matter if there is a small abnormal sound, it will generally disappear after a period of rotation and running-in. Therefore, the important content mentioned today is the louder and more special sound.

How to choose turntable bearing according to hardness?

The turntable bearing can be continuously strengthened in terms of hardness. If the turntable 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 turntable bearing box, check the roundness and cylindricity of the inner hole, and use the inner hole micrometer to check, the force distribution of the turntable 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.
