Design optimization of forklift sheaves in heavy-loaded working environments

1. Challenges of heavy-loaded working environments to forklift sheaves
Heavy-loaded working environments usually refer to the need to carry heavy and large-volume goods, such as heavy machinery and equipment, bulk raw materials, etc. In this environment, the forklift sheave not only needs to bear the weight of the goods, but also needs to cope with the huge impact force generated by the forklift during driving and lifting. Therefore, the design of the forklift sheave must be able to withstand high-intensity wear and impact to ensure the stability and reliability of the transmission system.

2. Increase the thickness and diameter of the forklift sheave
In order to improve the carrying capacity of the forklift sheave, its thickness and diameter need to be increased during design. The increase in thickness can increase the strength and stiffness of the sheave, enabling it to better resist the effects of load and impact. The increase in diameter can reduce the wear rate of the sheave during the transmission process and extend its service life. Of course, while increasing the thickness and diameter, the weight and manufacturing cost of the sheave also need to be considered to ensure the economy and practicality of the design.

In terms of material selection, we can choose high-quality materials such as high-strength alloy steel or cemented carbide. These materials have excellent mechanical properties and wear resistance, which can meet the high requirements of forklift sheaves in heavy-duty working environments. In addition, through advanced heat treatment processes such as quenching and tempering, the hardness and wear resistance of the sheave can be further improved, making it more suitable for heavy-duty working environments.

3. Optimize tooth design to reduce wear
In addition to increasing thickness and diameter, optimizing tooth design is also an important means to improve the load-bearing capacity and wear resistance of forklift sheaves. Reasonable tooth design can ensure smooth meshing of the chain and sheave, reduce wear and noise, and improve transmission efficiency.

In tooth design, we can use high-efficiency transmission tooth shapes such as involute tooth shape or circular arc tooth shape. These tooth shapes have better meshing performance and wear resistance, and can reduce friction and wear between the chain and sheave. At the same time, we can further optimize the tooth design by adjusting parameters such as pitch, tooth height and root fillet to meet the transmission requirements under different working conditions.

In addition, we can also perform special treatments on the sheave surface, such as shot peening, carburizing and quenching, to improve its surface hardness and wear resistance. These special treatments can further extend the service life of the sheave, reduce the frequency of maintenance and replacement, and reduce operating costs.
