Product Description

Product Description

Casting large gear wheel

Cast gears play a vital role in the mechanical transmission system, whose main function is to transmit power and motion through the meshing of teeth. Compared with other manufacturing processes, casting is particularly suitable for the production of complex shapes and large sizes of gears, with the advantages of cost-effective and fast production efficiency. The cast gear can withstand high loads and stresses, ensuring the stability and reliability of the mechanical system.

Production Process

Casting

Casting blank production is the basis of the whole process, first prepare the mold according to the design drawing. Commonly used casting methods include sand casting, precision casting and so on. At this stage, a suitable material (such as cast iron or cast steel) needs to be selected, the molten metal is poured into the mold, and the basic shape of the gear is formed after cooling. This step requires strict control of the pouring temperature and speed to ensure the quality of the casting.

Rough Machining

Heat treatment

After the blank is obtained, it is roughed to remove excess material and initially form the gear profile. Usually use lathes, milling machines and other equipment to process the outer circle, inner hole and end face. The main purpose of roughing is to provide accurate positioning benchmarks for subsequent processes and reduce the workload of finishing.

In order to enhance the hardness and wear resistance of the gear, it must be heat treated. Common heat treatment methods are quenching, tempering and so on. By heating to a specific temperature and then rapid cooling (quenching), followed by holding at the appropriate temperature (tempering), the mechanical properties of the gear can be significantly improved, making it more resistant to wear and fatigue damage.

Finishing Machining

Finishing is a key step to achieve the final size and shape of the gear, including hobbing, gear shaping and other processes to accurately machining the gear tooth shape. In this process, the machining accuracy should be strictly controlled to ensure that the tooth shape meets the design requirements. In addition, the gear needs to be measured and inspected to verify that its dimensional accuracy and surface quality are up to standard.
