The Advantage of Powder Metallurgy Process

1. Cost-effective: The final products can be compacted with the powder metallurgy method, and there is no need for or can shorten the processing of the machine. It can save material greatly and reduce the production cost.
2. Complex shapes: Powder metallurgy allows us to obtain complex shapes directly from the compacting tooling, without any machining operations, like teeth, splines, profiles, frontal geometries, etc.
3. High precision: Achievable tolerances in the perpendicular direction of compacting are typically IT 8-9 as sintered, improvable up to IT 5-7 after sizing. Additional machining operations can improve the precision.
4. Self-lubrication: The interconnected porosity of the material can be filled with oils, obtaining a self-lubricating bearing. The oil provides constant lubrication between the bearing and shaft, and the system does not need any additional external lubricant.
5. Green technology: The manufacturing process of sintered components is certified as ecological because the material waste is very low, the product is recyclable, and the energy efficiency is good because the material is not molten.

Performance Characteristics of Internal Gear

Internal gear offers several performance characteristics that make it a valuable component in various applications. Firstly, its compact design allows for efficient power transmission in tight spaces. Secondly, the meshing of the gear teeth provides high torque capacity and smooth operation. Additionally, the internal gear’s ability to handle high loads and distribute stress evenly ensures its durability. Furthermore, its versatility allows for customization to suit specific application requirements. Lastly, the self-lubricating properties of internal gear reduce friction and extend its service life.

Types and Characteristics of Internal Gear

Internal gears can be classified into different types based on their tooth profile and application requirements. The most common types include spur, helical, herringbone, and double helical gears. Each type possesses unique characteristics that make it suitable for specific applications. For instance, spur gears are known for their simplicity and cost-effectiveness, while helical gears offer smoother and quieter operation. Herringbone gears provide improved load distribution and reduced axial thrust, making them ideal for high-load applications. Double helical gears, also known as herringbone gears, combine the advantages of helical and herringbone gears. They provide excellent load-carrying capacity and reduce gear noise.

Advantages of Internal Gear Materials

The choice of materials for internal gears greatly influences their performance and durability. Different materials offer varying advantages based on the requirements of the application. Steel internal gears are widely used due to their high strength and durability. They can withstand heavy loads and provide reliable performance. Cast iron internal gears offer excellent wear resistance and are suitable for applications where shock absorption is required. Additionally, nylon internal gears are lightweight, corrosion-resistant, and provide self-lubrication, making them ideal for applications with low noise requirements.

Application of Internal Gear

Internal gears find extensive applications in various fields, including Automotive Transmissions, Worm Gear Drives, Gear Pumps, Bicycles and Cycling Equipment, and Robotic Systems. In Automotive Transmissions, internal gears play a crucial role in transferring power from the engine to the wheels, ensuring smooth acceleration and efficient gear ratio changes. Worm Gear Drives utilize internal gears to achieve high torque transmission and self-locking capabilities. Gear Pumps employ internal gears to provide precise fluid displacement and efficient flow control. Bicycles and Cycling Equipment use internal gears for gear shifting and power transmission. Robotic Systems rely on internal gears for precise motion control and efficient power transfer.
