What is a shield machine bearing

With the acceleration of urbanization, shield machines are playing an increasingly important role in underground engineering.As an important component of shield machines, the bearings of shield machines are of great significance for the normal operation of shield machines and the smooth progress of underground engineering.

The shield machine bearing is a special type of bearing, which consists of a bearing housing, a bearing cover, rolling elements, a retainer, and seals.The rolling elements are the core components of the shield machine bearing, which are composed of a series of spherical or cylindrical steel balls that can roll between the inner and outer rings of the bearing.The retainer is used to hold the rolling elements in place and guide them to roll correctly between the inner and outer rings of the bearing.The seals are used to prevent dust, dirt, and other impurities from entering the bearing, ensuring the normal operation of the bearing.

As an important component of modern tunnel construction, shield bearings have a series of unique characteristics and advantages.

Features of shield machine bearings

large-scale design

The bearings of shield machines are usually designed with large size to meet the requirements of large-diameter and high-load tunnel tunneling.This design enables the bearings of shield machines to have higher load-bearing capacity and stability, and better adapt to complex geological conditions and harsh working environments.

High-precision manufacturing

The manufacturing of shield machine bearings requires high-precision processing and manufacturing techniques to ensure their accuracy and stability.During the manufacturing process, each component of the shield machine bearing requires strict inspection and control to ensure its geometric and fit accuracy.In addition, the surface treatment and heat treatment processes of the shield machine bearing also require strict control to ensure its hardness and wear resistance.

Long-life design

The shield machine bearing adopts a long-life design, which enables stable operation for a long time under harsh working conditions.This design makes the shield machine bearing more reliable and durable, greatly reducing the frequency of maintenance and replacement, and improving equipment utilization and construction efficiency.

Low friction performance

The friction performance of shield machine bearings has a significant impact on the energy consumption and tunneling efficiency of the equipment.Therefore, the friction performance of shield machine bearings needs to be well controlled.Modern shield machine bearings often use low-friction materials and surface treatment techniques to reduce the friction coefficient and improve tunneling efficiency.

Advantages of shield machine bearings
