Gear customization involves multiple key aspects such as material selection, process flow, production cycle, and supplier selection. The following is a specific analysis:

Material selection:

The selection of gear materials should be based on actual usage conditions and requirements. Steel is a common gear material with good toughness and impact resistance. Its mechanical properties and tooth surface hardness can also be improved through heat treatment or chemical heat treatment. Forged steel is the main material for manufacturing gears, usually made of carbon steel or alloy steel with a carbon content of about 1%. For high-speed light load and low precision gear transmission, non-metallic materials (such as cloth plastic, nylon, etc.) are commonly used to make small gears in order to reduce noise, while large gears are still made of steel or cast iron.

technological process:

The process flow of gear customization usually includes ordinary machining, gear hobbing, gear hobbing, gear shaving, hard machining, gear grinding, honing, drilling, inner hole grinding, welding, measurement and other steps. Different processing techniques are suitable for different types of gears and precision requirements.

Production cycle:

The production cycle for customized powder metallurgy gears is usually around 15 to 60 days, which is influenced by various factors such as product complexity, order quantity, raw material supply, production process, and mold manufacturing. For example, gears with simple structures and conventional specifications may have a shorter production cycle, while gears with complex structures and special requirements may have a longer production cycle.

Supplier selection:

When choosing a customized gear supplier, it is necessary to consider their production capacity, technical level, quality control, and after-sales service.
