What is the function of the track pin on the track?

2023-05-08




The track pins connect the track shoes to form a track chain link. The track is driven by the driving wheel and is a flexible link around the driving wheel, road wheel, induction wheel and supporting pulley. The track is composed of track shoes and track pins, etc. There are holes at both ends of the track shoes, which are meshed with the driving wheel, and there are inducing teeth in the middle, which are used to regulate the track and prevent the track from falling off when the tank turns or rolls. There are reinforced anti-skid ribs (referred to as patterns) on one side to improve the firmness of the track shoes and the attachment of the track to the ground.


Focus on. The track must have a track pin, because the role of the track pin is to connect the track shoe to the track shoe, and the road wheel is also essential, and the role of the road wheel is to push the track forward.


Excavator track pin is one of the important parts on the track, it bears the role of supporting the track and transmitting power. The track pins are usually made of high-strength alloy steel or cast steel. This material has the characteristics of high strength, high hardness, high wear resistance and high corrosion resistance, and can meet the requirements of roadheaders under harsh working conditions. High-strength alloy steel track pin is a material widely used at present. Its main components are carbon, manganese, silicon, chromium, molybdenum and other elements, and it has the characteristics of high strength, high hardness and high toughness. Cast steel track pins are manufactured through a casting process, which has high strength and hardness, and also has good wear resistance and corrosion resistance. In short, the material of the track pin of the excavator should be selected according to the specific use environment and working conditions to ensure that it has sufficient strength and durability to ensure the normal operation of the roadheader.
