Application of pei material in turntable bearing seat

Pei turntable bearing housing is a large and extra large bearing housing that can accept comprehensive loads and has a special structure. It has the characteristics of compact structure, sensitive rotation, and convenient device maintenance. Compared with ordinary bearing blocks, machining pei turntable bearing blocks have the following obvious features:

1. Dimensions

The diameter is usually 0.4cm ~ 10m, and the maximum can reach 40m.

2. High carrying capacity

Generally it can accept axial load, radial load and overturning moment load together.

3.Low speed

The task speed is lower than 10r / min, and in a few cases, it does not perform successive rotations, only rotates within a certain angle, and performs swing motion.

4.With bearing block device hole

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

5. No pivot

The inner or outer ring is equipped with a machining gear for rotary drive.

6. With smooth oil holes and sealed installation.

The identification of the important construction methods of the pei turntable bearing seat are: four-point contact ball pei turntable bearing seat, double row angular contact thrust ball pei turntable bearing seat, cylindrical roller pei turntable bearing seat, tapered roller pei turntable bearing seat, three Row cylindrical rollers are matched with pei turntable bearing seats.

According to whether the teeth can be distributed with gears and gears, they are divided into different structures, such as non-tooth type, external tooth type or internal tooth type.

The four-point contact ball pei turntable bearing seat has a high static load capacity, the cylindrical roller pei turntable bearing seat has a high dynamic load capacity, and the tapered roller pei turntable bearing seat can be preloaded to improve the rigidity and support. Slewing accuracy, while three rows of cylindrical rollers combined with pei turntable bearing housings increase the height of the machining bearings housings to improve the bearing capacity. Different types of raceways are accepted for load identification, so the bearing housing diameter can be greatly reduced under the same stress condition. Therefore, it makes the host more compact and is a pei turntable bearing seat with high load capacity.

The pei turntable bearing seat is commonly used in large-scale rotary installations such as lifting and transportation machinery, mining machinery, construction machinery, port machinery, marine equipment, and high-precision radar.
