The wider the track shoe is not the better, why?
The wider the track shoe is not the better, why? The track shoe is one of the chassis parts of construction machinery, and is a wearing part of the construction machinery used. At present, it is commonly used on construction machinery such as excavators, bulldozers, crawler cranes, and pavers. The track is a flexible chain ring driven by the driving wheel and surrounding the driving wheel, road wheel, idler wheel and idler wheel. The track consists of track shoes and track pins. The track pins connect the track shoes together to form the track links. There are holes on both sides of the track shoe, which mesh with the driving wheel, and there are guiding teeth in the middle, which are used to straighten the track and prevent the track from falling off when the tank turns or rolls. In order to improve the firmness of the track shoes and the adhesion between the track and the road. The track shoes on construction machinery come from materials, which can be divided into: steel and rubber. Steel track shoes are mostly used on equipment with relatively large tonnage, and rubber track shoes are mostly used on equipment with small tonnage. The overall track shoe of the paver is made of imported rubber, and strict production technology ensures the quality of the product. Should the track shoes be wide or narrow? Some people say that the wide one doesn't trap the car, and some people say that the narrow one saves fuel and runs faster. So how exactly do you need to choose a track shoe? Different track shoes have a great impact on the production efficiency of crawler crane and the service life of the chassis system. The selection of track shoes requires comprehensive consideration of road conditions, application conditions and the wear life of chassis parts. When the width of the track shoe increases, the buoyancy of the track shoe increases, which can adapt to more working conditions; but the maneuverability of bulldozing decreases, and the structural life of the track shoe and other parts of the bottom plate also decreases. Moreover, the wider the track shoe, the greater the friction with the road surface, the greater the loss of power consumption during driving, and the higher the fuel consumption of the crawler crane. Therefore, the wider the track shoe is not the better, a basic principle when selecting the track shoe is: the narrower the track shoe is, the better when the equipment is not trapped during operation.
Structural performance characteristics of steel crawler undercarrige
Structural performance characteristics of steel crawler chassis 1. Support the weight of the host, with the function of moving forward, back and back. 2. Steel cracks use Japanese technology to produce construction machinery, load carrying capacity, large traction, low noise, non-injury, asphalt road, with good driving performance. 3. It is equipped with an internal low-speed large torque motor walking reducer with high pass performance. 4. Distance hierarchical, structural strength, high stiffness, and bending. 5. Heavy wheel, guide wheel adopts deep groove ball bearings, lubricated in one-time plus oil, is exempt from maintenance and maintenance. 6. The shaft end double sealing structure ensures that the lubricant seal is not leaking, and the mud water can be prevented from entering the cavity. 7. Heavy wheel, guide wheel, drive wheel tooth with alloy steel and treated with quenching, wear resistance, long service life. 8. Spring tensioning mechanism color screw adjustment, high reliability.
Steel track shoe type --- crawler crane undercarrige parts
Steel track shoe type The track shoe is one of the chassis parts of the construction machinery, and it is a kind of wearing parts of the construction machinery used. The current track shoe materials mainly include rubber, high manganese steel, medium manganese steel, low alloy steel, ductile iron, aluminum alloy and aluminum matrix composite materials, and the steel track shoe is the most widely researched and applied, it is mainly divided into the following Three categories: 1. High manganese steel High manganese steel, also known as Hadfield steel, has a standard composition of (wt%) Fe-12Mn-1.2C. It is a typical wear-resistant steel that resists strong impact wear because of its high strength, good toughness, and strong work hardening effect. , shows superior wear resistance under strong impact conditions, and is widely used in mining, metallurgy, automobiles, construction machinery, railways and other equipment parts. At present, most of the track shoes for tanks and heavy-duty vehicles still use ZGMn13 high manganese steel. After the high manganese steel is water toughened, its strength and hardness are not high, and its unique feature is work hardening. 2. Medium manganese steel Since the wear resistance of high manganese steel is conditionally limited, its high wear resistance is only under the conditions of strong impact (ie high stress Under the condition of force working conditions), enough work hardening can be produced. By reducing the manganese-carbon content, the medium-manganese steel has been researched and developed for the application of medium and small energy impact conditions, and the application effect is superior to that of the high-manganese steel. The composition design of medium manganese steel is very critical, which is mainly achieved by controlling the content of manganese and carbon elements. The manganese content is generally 6% to 10%, and the carbon content is usually 0.6% to 1.0%. 3. Low alloy steel In recent years, there have been many reports on the research and application of low-alloy wear-resistant cast steel in track shoes. By optimizing the chemical composition, casting process and heat treatment process, the required mechanical properties can be obtained, which can meet the requirements of the track shoe. Among them, typical medium carbon silicon manganese steels (such as 31Mn2Si, 40Mn2Si) and medium carbon low alloy steels for track shoes such as rare earth, boron, nickel and other elements (35MnTiB, 32CrMoB, 35CrNiMo, CrMnSiMoRE) are added. Low alloy cast steel has the characteristics of low alloy content (5% of total alloy elements), low cost, wide source, good comprehensive mechanical properties, and simple manufacturing process. It is a track shoe material with good application prospects. (Purple Flame)
How to replace the idler wheel of the crawler crane
How to replace the idler wheel of the crawler crane: 1. First remove the crawler from the crawler crane. Remove the one-way valve at the grease nipple, release the butter, and push the guide wheel inward with a bucket to make the track as loose as possible. Be sure to remove the one-way valve, otherwise the track will not be easy to remove or install. 2. Install the guide wheel. The guide wheel installation is the same as the general wheel installation method. with a jack Lift up the crawler, then use a screwdriver to unscrew the screw, after removing it, Install the new wheel, apply lubricating oil, and complete the installation.
