The principle of crawler walking of excavator

The crawler walking principle of the excavator mainly involves knowledge of mechanical dynamics, friction and hydraulic systems. The crawler walking device enables the excavator to walk and operate stably in various terrain conditions, and has good obstacle-crossing ability and traction.

First, the crawler track of the excavator transmits power to the crawler chain through the cooperation of the sprocket and the driving wheel. During this process, the tension of the track chain creates a certain positive pressure between the track and the ground, thereby forming friction. When the driving wheel rotates, the crawler chain moves forward under the action of friction, thereby enabling the excavator to move.

Secondly, the design of the crawler walking device also fully considers stability and traction under different terrain conditions. Taking common excavator tracks as an example, rubber track pads are usually designed with corrugated textures or raised structures to increase friction with the ground. In addition, the outside of the excavator track is usually designed with a protective cover to prevent mud, sand and other debris from causing damage to the track, and also further improves the friction between the track and the ground.

In addition, the control of the excavator's traveling speed and direction is also achieved through the hydraulic system. The excavator driver can adjust the hydraulic oil flow and direction as needed to control the speed and steering of the driving wheels and adjust the excavator's walking speed and direction.

In short, the crawler walking principle of the excavator is mainly based on the friction between the crawler track and the ground, and the speed and direction are adjusted through the hydraulic system. This design enables the excavator to walk and operate stably in various terrain conditions, and has good obstacle surmounting ability and traction. At the same time, the maintenance and upkeep of the crawler walking device is also very important. The wear and tension of the crawler tracks need to be checked regularly to ensure the normal walking and operation of the excavator.

In the specific working process, the crawler walking device of the excavator also involves the working principles of a series of complex mechanical and hydraulic systems. For example, the driving wheel transmits power to the crawler chain through the transmission of the sprocket chain. At the same time, the crawler tensioner also plays a key role. It can ensure that the crawler track always maintains a certain tension during work, so that the gap between the crawler track and the ground is generate enough friction. In addition, the design of the excavator crawler traveling device also needs to consider factors such as mechanical efficiency and reliability.

In addition, the selection of materials, optimization of processes, and issues such as lubrication and heat dissipation need to be fully considered during the design and manufacturing process of crawler walking devices. These factors will affect the performance and service life of the crawler running device. Therefore, when choosing an excavator crawler traveling device, you need to consider multiple factors, such as price, quality, performance, after-sales service, etc., in order to choose the product that best suits you.

In addition, excavator operators also need to have certain skills and experience to be proficient in the use and maintenance of crawler walking devices. During operation, it is necessary to pay close attention to factors such as track wear, tension, and terrain conditions, and make timely adjustments and maintenance to ensure the normal walking and operation of the excavator. At the same time, regular inspection and maintenance of the crawler walking device, such as cleaning and lubrication, are also required to ensure its normal operation and work efficiency.

In short, the crawler walking principle of the excavator involves multiple aspects of knowledge and skills, including mechanical dynamics, friction, hydraulic system, etc. Only by fully mastering these knowledge and skills can we better use and maintain the excavator crawler walking device and improve its performance and service life.
