Electric tool hammer gear box is what material

The gearbox in an electric hammer or hammer drill is a critical component that plays a significant role in the tool's operation. The materials used in the gearbox can vary depending on the specific make and model of the tool, as well as its intended use. However, some common materials used in the construction of gearbox components include:

1. Metal Alloys: Many gearbox components are typically made from various metal alloys, such as steel or aluminum. Steel is commonly used for gears and shafts due to its strength and durability. Aluminum may be used for certain lightweight components.

2. Plastic: Some gearbox components, such as gear housing covers or protective shrouds, may be made from high-strength engineering plastics. These plastics are chosen for their lightweight properties and resistance to impact.

3. Bearings: Bearings within the gearbox often use materials like chrome steel or stainless steel for their ball bearings and races. These materials provide smooth movement and durability.

4. Seals and Gaskets: Materials like rubber, silicone, or other elastomers are used for seals and gaskets to prevent dust and moisture from entering the gearbox, protecting the internal components.

5. Heat-Treated Steel: For gears and other high-stress components, heat-treated steel is frequently used to enhance strength and wear resistance.

6. Bronze or Brass: In some cases, bronze or brass may be used for components like bushings or thrust washers due to their self-lubricating properties.

The choice of materials for gearbox components is influenced by factors such as the expected load and stress on the components, the desired durability, and the cost-effectiveness of the materials. Electric hammers and hammer drills are often subjected to high levels of stress and vibration during use, so the gearbox materials are selected to withstand these conditions and ensure the tool's reliability and longevity.

The specific materials used in a particular tool's gearbox can vary by manufacturer and model, so it's essential to refer to the tool's documentation or contact the manufacturer for precise information on the gearbox materials used in your specific electric hammer or hammer drill.
