Application of  Oilless Bush in excavators

The excavator is divided into the vehicle part, the disembarkation part, and the working device part. The disembarkation part is mainly the walking mechanism, and the disembarkation part is mainly the control. The working device, as the name implies, is the part used to work. The excavator is the big arm, the small arm, the shovel bucket, and some of them have earth loosening apparatus. The most important is the hydraulic system, the main pump, the main cutting, the pilot system, and so on. Self-lubricating bearings are mainly used in chassis moving mechanisms, body parts, hydraulic components, and other components.

The structural members of the excavator working device and the oil red are connected by a pin shaft at each joint hinge point and supporting seat. During the work, they bear a large load and wear between each moving part. Meanwhile, during the work, the bearing capacity of the excavator working device is characterized by high load and low speed.

In addition, when the excavator excavates and moves the earth, the working device, under the action of each oil cylinder, has frequent rotation and high frequency of repeated action, that is, the relative movement of the grinding parts is frequent, in order to ensure that each part rotates flexibly and works reliably when working, so it is suitable to use solid self-lubricating bearing on the working device of the excavator.

In excavator with self-lubricating bearing (graphite and copper set Oilless Bush) of substrate material choice, according to the main failure form of bearing, and combining the characteristics of the engineering machinery use conditions changing, considering factors such as material strength, corrosion resistance, and adaptability, choose the solid self-lubricating bearing substrate material is brass, high carrying capacity of a higher force its allowable static bearing capacity is 250 n/mmi, allowable bearing capacity for low quick l00N/mm ‘, and good abrasion resistance.

The application of self-lubricating bearing (graphite copper sleeve Oilless Bush) in excavator effectively simplifies the mechanical design, and its simple structure, good technology, reduce the maintenance cost of the machine, reliable quality plate, help to improve the working reliability of the whole machine. At the same time, the solid self-lubricating bearing has superior performance in use and strong product competitiveness, so it will be more fully applied in the use of construction machinery in the future.

Viiplus is a professional graphite copper sleeve, self-lubricating oilless bush manufacturer, the company produces self-lubricating bearings, oil-free bushings, copper busbar copper, graphite, is widely used in the automobile industry, construction machinery, hydraulic machinery, wind power, high-speed train, plastic machinery, automatic production line, plastic packaging machinery and so on need to drive to refuel or difficult to form the part of the oil film, if you have any needs, can feel free to contact us.

There are a number of situations where selflubricating and pre-lubricated bearings of some kind should be considered by a designer.
