Structure and characteristics of Ningbo bearing turntable bearing block

Ningbo bearing turntable bearing block is a kind of large and super large bearing block which can accept comprehensive load and has special structure. It has the characteristics of compact structure, sensitive rotation and convenient equipment maintenance. Compared with the common bearing pedestal, the rotary bearing pedestal has the following obvious characteristics:

1. Overall dimension

The diameter is usually 0.4m-10m, and the maximum is 40m.

2. High bearing capacity

Generally, axial load, radial load and overturning moment load can be accepted together.

3. Low speed

The task speed is lower than 10R / min, and in a few cases, it does not rotate in succession, but only rotates in a certain angle and does swing movement.

4. With bearing seat device hole

It can be fixed on the upper and lower supports with screws.  

5. No center pivot

The inner ring or outer ring is provided with a rotating driving gear.

6. With smooth oil hole and seal installation.

There are four point contact ball bearing pedestal, double row angular contact thrust ball slewing bearing pedestal, inserting cylindrical roller slewing bearing pedestal, inserting tapered roller slewing bearing pedestal, and three row cylindrical roller matching turntable bearing pedestal.

According to whether it can be equipped with teeth and the scattered parts of gears, it can be divided into different structures, such as toothless type, external tooth type or internal tooth type.

Among them, the four point contact ball slewing bearing seat has higher static bearing capacity, the interleaved cylindrical roller bearing seat has higher dynamic bearing capacity, the inserted tapered roller bearing seat can improve the supporting rigidity and rotary accuracy by applying preload, and the three row cylindrical roller with rotary table bearing seat can increase the bearing seat height to improve the bearing capacity, and the load identification has different raceways Therefore, under the same stress condition, the diameter of its bearing pedestal can be greatly reduced, thus making the main engine more compact. It is a rotary table bearing seat with high load capacity.

Turntable bearing block is widely used in large-scale rotary installation of hoisting and transportation machinery, mining machinery, construction machinery, port machinery, ship machinery and high-precision radar.
