Application of Fasteners in Earthmoving Machinery

Application of Fasteners in Earthmoving Machinery

Excavating machinery is a kind of mechanical equipment used for digging, loading, and carrying soil and stone materials, which is widely used in construction, mining, farmland, and municipal engineering. And fasteners, as connecting and fixing parts, play an essential role in earthmoving machinery. This paper will introduce the application of fasteners in earthmoving machinery, including the types of fasteners, application scenarios, and requirements.

There are various fasteners: bolts, nuts, washers, pins, etc. In earth-moving machinery, standard fasteners include bolts connecting buckets and booms, nuts fixing track plates, pins connecting hydraulic cylinders, and so on. These fasteners ensure earthmoving machinery's proper functioning and efficiency by connecting and securing different components.

Fasteners are used in a wide range of application scenarios in earthmoving machinery. For example, the bolts connecting the bucket to the boom are subjected to tremendous tensile and shear forces and need sufficient strength and vibration resistance to ensure that the bucket does not fall off or loosen during operation. The nuts fixing the track plate also bear a lot of shock and vibration and need good anti-loosening and wear-resistant performance to ensure the track's regular operation and service life. The pin connecting the hydraulic cylinder needs to have high strength and corrosion resistance to ensure the regular operation and safety of the hydraulic cylinder.

The application of fasteners in earthmoving machinery also needs to fulfill specific requirements. First, the fasteners must have enough strength and stiffness to withstand the various forces and loads of excavating machinery. Secondly, fasteners need good sealing performance to prevent dust, mud wat, er, and other substances from intruding into the connection parts, affecting the everyday work of excavating machinery. At the same time, fasteners must also have good corrosion resistance to cope with the harsh working environment and conditions. Finally, the installation and use of fasteners must comply with the relevant standards and norms to ensure the safety and reliability of earthmoving machinery.

The application of fasteners in earthmoving machinery cannot be ignored. Different fasteners bear the critical task of connection and fixation in earthmoving machinery, ensuring regular operation and working efficiency. Therefore, when designing, selecting, and using fasteners, it is necessary to consider the environment and requirements of earthmoving machinery, select the appropriate fasteners, and install and use them according to relevant standards and specifications. Only in this way can we ensure the excavating machinery's safety, reliability, and durability and improve the working efficiency and production benefits.

What are the applications of anti-loosening nuts in construction machinery, the application field of anti-loosening nuts in construction machinery, and anti-loosening nuts in construction machinery applications?

　Construction machinery is characterized by high engine power, working conditions, and shock load, resulting in a corresponding strong vibration. Under the action of shock vibration, bolts, and nuts generally loosen and fall off. Each manufacturer has unique skills to prevent the failure of fasteners; some use pre-set torque nuts, some use flat-head nuts, and some use chemical glue coating.

　　Although these methods have a specific anti-loosening effect, there are two common shortcomings: First, the reuse effect is poor; some are disposable, at most four to five times; Second, the maintenance is not convenient; loading and unloading of the nut consumes a lot of energy, and the chemical glue pollutes the environment, and the construction workers also cause personal injury. The lock nut can play an excellent anti-loosening effect, has a good reuse performance, is easy to install and dismantle, and is gradually applied to the critical components of construction machinery. At present, the following components are mainly used in construction machinery:

　　Mixer, crane: bracket connection, reducer seat, tug wheel, etc. Vibratory roller: coupling, engine universal joint.

　　Excavator: slewing bracket, track wheel, crushing hammer. Anti Loosening Nut originated from abroad; it is permanently attached to the threads with special engineering plastics so that the inner and outer threads, in the process of contraction, the engineering plastics are squeezed and produce a strong reaction force, which significantly increases the friction between the inner and outer threads, and provides an absolute resistance to vibration. Bulldozer: Crawler type bulldozer.

Loaders: drive shafts, main drive differentials, large parachutes. Anti Loosening Nut originated from abroad; it is permanently attached to the threads with special engineering plastics so that the internal and external threads, in the process of contraction, the engineering plastics are squeezed and produce a strong reaction force, which significantly increases the friction between the internal and external threads, providing an absolute resistance to vibration. Fasteners, or standard parts in the market, are mechanical elements that can fix or bond two or more components together. It is characterized by various varieties and specifications, different performances and uses, and an extremely high degree of standardization, serialization, and generalization. Fasteners are the most widely used mechanical essential parts, and the demand is excellent.
