I. The function of the excavator guide wheel
The excavator guide wheel, also known as the hydraulic wheel or the steering wheel, is a component that helps the excavator to walk.Generally, excavators are equipped with 3 to 4 guide wheels to control the direction and tension of the track.The position of the guide wheel is usually at the bottom of the track, connected to the track rolling system. The rotation of the wheel can change the direction of movement of the track.
II. Material of excavator guide wheel
There are generally three types of material for excavator guide wheels, namely wear-resistant alloy steel, cast steel, and cast iron.Different materials for guide wheels vary in terms of pressure resistance, wear resistance, and manufacturing costs.
1. Wear-resistant alloy steel
Wear-resistant alloy steel is a high-wear-resistant alloy steel, also known as "high alloy wear-resistant plate" on the market.It is a type of wear-resistant steel plate, mainly used as a material for wear-resistant parts of construction machinery such as excavators.The wear-resistant alloy steel guide wheel has better wear resistance and corrosion resistance, and is suitable for harsh working conditions.
2. Cast steel
Cast steel is a casting material with high material strength and strong resistance to deformation. Therefore, when installed on the excavator guide wheel, it has particularly good results.The guide wheel made of cast steel has high compressive strength, wear resistance, and corrosion resistance, and is suitable for moderate working conditions.
3. Cast iron
Cast iron is a cheap and easy-to-process material, but it is relatively brittle and prone to breakage and cracking.Cast iron guide wheels are cheap, but they have poor wear and corrosion resistance and are suitable for light-duty use.
III. Suggestions for selecting the material of the guide wheel
In terms of material selection for the excavator guide wheel, the needs under different working conditions need to be considered.Generally, the excavator guide wheel will wear more under high-load working conditions, so it is better to choose a wear-resistant alloy steel guide wheel in this case.However, in medium-load working environments, a cast steel guide wheel can be selected.Of course, for light-load use, a cheap cast iron guide wheel can also be selected.
Conclusion:
Excavator guide wheels are an integral part of the excavator control system. Inputting the appropriate material can improve its durability and reliability.When selecting the material, it is necessary to consider the working conditions and requirements of the excavator guide wheel.I hope this article can provide some useful suggestions and references for everyone.
