INGCO RH16008-SP-74-83 Rotary Hammer-Gear Assembly

The INGCO RH16008-SP-74-83 Rotary Hammer-Gear Assembly is a crucial part in the Rotary Hammer. It has different features and components that compliments it.

Let’s delve into the fundamental aspects of gear technology, including components and dimensions.

1. Gear Components:
   • Toothed Crown: This part transfers rotational movement.
   • Bearing: The bearing connects the gear to a shaft (such as a motor or another part of the mechanism).
   • Partition: Sometimes, the partition appears in the form of arms.
2. Diameter of Gears (Size):
   • The size of gears is determined by several factors:
     • Reference Diameter (d): The base circle, pitch, tooth thickness, tooth depth, addendum, and dedendum contribute to determining the reference diameter.
3. Basic Gear Terminology:
   • Module (m): The unit representing gear tooth sizes. It’s used to express the size of gears. Other methods are also employed, but module size is a common reference.
   • Pitch (p): The distance between corresponding points on adjacent teeth.
   • Circular Pitch (CP): Denotes the reference pitch. For instance, gears can be produced at integral values like CP5, CP10, CP15, etc.
   • Diametral Pitch (DP): Used in the USA, UK, and other countries.
   • Pressure Angle (α): Determines the tooth profile. Commonly set to 20°, but 14.5° gears were prevalent. It’s the leaning angle of a gear tooth.
   • Number of Teeth: The count of gear teeth. It’s a fundamental element in gear composition.
   • Tooth Depth (h): The distance between the tooth tip and the tooth root.
4. Tooth Profiles:
   • ISO and JIS standards specify tooth profiles (full depth). Key terms include:
     • Addendum (ha): Distance between the reference line and the tooth tip.
     • Dedendum (hf): Distance between the reference line and the tooth root.

Remember, these elements form the foundation for understanding gear technology and designing effective gear systems!
