Engineering machinery

Engineering machinery refers to various mechanical equipment used in the field of engineering construction, including excavators, loaders, cranes, rollers, pavers, etc. These equipment play a very important role in engineering construction, which can greatly improve construction efficiency and quality, while also reducing labor costs. This article will introduce the basic knowledge and purchasing skills of construction machinery. Engineering machinery is usually composed of mechanical, hydraulic, electrical, and transmission systems. Among them, the mechanical system is the core part of engineering machinery, including working devices, frames, wheels, walking mechanisms, etc. The hydraulic system is the power source of construction machinery, which can achieve efficient and precise control. The electrical system is the "brain" of engineering machinery, controlling the operation of the entire equipment. The transmission system is the power transmission system of construction machinery, including the gearbox, transmission shaft, differential, etc.

For example, equipment such as excavators, loaders, and rollers can quickly complete earthwork excavation, loading, and compaction operations, greatly improving construction efficiency. In addition, some engineering equipment can also perform various operations, such as backfilling, leveling, and rolling of excavators, further improving construction efficiency.

Engineering machinery must be able to ensure normal operation in harsh construction environments, therefore it has high reliability. These devices typically use high-quality materials and components, undergo strict quality control and durability testing to ensure the reliability and service life of the equipment. In addition, modern construction machinery also adopts many advanced electronic control technologies, such as fault diagnosis and early warning systems, further improving the reliability of the equipment.

Modern construction machinery is increasingly emphasizing versatility to meet the needs of different construction tasks. For example, an excavator can achieve different functions by replacing different working devices, such as excavation, loading, handling, crushing, etc. This versatility enables the same equipment to complete more construction tasks, improving equipment utilization and construction efficiency.

Construction machinery has a wide range of adaptability and can adapt to various construction environments and task requirements. For example, excavators can be used for various operations such as excavation, loading, and transportation, and can operate normally in different terrain and climate conditions. In addition, construction machinery can also be customized to meet the needs of specific construction tasks.

LTZC Bearings mainly used in Agricultural machinery

Three Row Cylindrical Roller Slewing Bearing

The Triple-row Roller Slewing Bearing has three seating rings, which separate the upper, lower and radial raceways. It can specify the loads of each row of rollers. Moreover, its load carrying capacity and it can bear different loads simultaneously.

Double Row Ball Slewing Bearings

Double-row ball slewing ring with same diameter balls is usually used for wind driven generators and concrete pump trucks. In wind driven generator applications, double-row ball slewing ring is often installed at the bottom of propellers for variable pitch control which requires zero clearance, large start friction moment and high running accuracy.

Four Point Contact Ball Slewing Bearing

Four-point contact ball bearing is comprised of an outer ring and an inner ring in integral structure or split structure. The two split rings of bearings in split structure are bolted together before delivery. Usually cages or spacers can be found in four-point contact ball bearings.

Cross Cylindrical Roller Slewing Bearing
The Single-row Crossed Roller Slewing Bearing consists of two seating rings. It has compact structure, light weight, and high manufacturing accuracy. Due to the small assembly clearances, it has high requirements for the assembly accuracy. The rollers are 1:1 cross arranged. It can bear the axial force, the overturning moment and a relatively large radial force simultaneously.

Characteristics of Engineering machinery bearings

High carrying capacity

Strong durability

Good anti friction performance

Features such as high accuracy and stability

Able to meet the work needs of various harsh environments. These characteristics make engineering machinery bearings an indispensable part of engineering machinery, providing strong guarantees for the stability and reliability of mechanical equipment.

1、 High load-bearing capacity of engineering machinery bearings

Construction machinery often needs to withstand huge loads, so bearings are required to have high load-bearing capacity. Engineering machinery bearings adopt optimized design, which has a large bearing capacity and can withstand axial and radial composite loads. In addition, engineering machinery bearings also have high stiffness and stability, which can ensure that they still maintain their accuracy and stability under high loads.

2、 Strong durability of engineering machinery bearings

Construction machinery often requires continuous operation on construction sites, therefore requiring bearings to have a longer service life. Engineering machinery bearings use high-quality materials and advanced processing techniques, which have a long service life. These bearings can withstand long-term high load working conditions and maintain their original performance and accuracy.

3、 Good anti friction performance of engineering machinery bearings

Engineering machinery bearings need to withstand significant friction during their operation, therefore they are required to have good anti friction performance. Engineering machinery bearings use materials with low friction coefficients and surface treatment processes, which can effectively reduce friction and improve the service life of bearings. In addition, these bearings also have good lubrication performance, which can ensure normal operation in poorly lubricated environments.

4、 High precision and stability of engineering machinery bearings

Engineering machinery bearings need to have high accuracy and stability to ensure the accuracy and stability of mechanical equipment. These bearings adopt advanced processing technology and precise detection methods, which can ensure their accuracy and stability. In addition, these bearings also have good coaxiality and vibration resistance, which can effectively reduce the vibration and noise of mechanical equipment.

5、 Good Environmental Adaptability of Engineering Machinery Bearings

Construction machinery often needs to work in harsh environments, so it is required to have good environmental adaptability. The engineering machinery bearings adopt a sealed design, which can effectively prevent dust, water, and other impurities from entering the interior of the bearings, ensuring their normal operation. In addition, these bearings also have good corrosion resistance and can operate normally in corrosive environments such as acidic and alkaline environments.
