A 25 Teeth Gear 6mm typically refers to a geared component with 25 teeth and a 6mm diameter bore. It is commonly used in mechanical and robotics applications to transmit rotational motion between two rotating parts (such as shafts or motors). Here are the detailed specifications and features of a 25 Teeth Gear with a 6mm bore:

Key Specifications of 25 Teeth Gear 6mm:

1. Number of Teeth:

• 25 Teeth: The gear has 25 individual teeth that mesh with another gear to transfer motion and torque. The number of teeth plays a role in determining the gear ratio, speed, and torque of the system.

2. Bore Diameter:

• 6mm Bore: This is the hole at the center of the gear, through which a 6mm shaft can be inserted to mount the gear onto a motor or another rotating shaft. It ensures a snug fit and secure mounting.

3. Pitch (Tooth Pitch / Module):

• Pitch: This refers to the distance between two adjacent teeth, which determines how fine or coarse the gear teeth are. In gears, this is typically measured in terms of module (mod) or diametral pitch (DP). The module is commonly used in metric systems, and this would define the size of the teeth.
  • Typical modules for small gears like these could be 0.5 or 1.0, but the exact value may vary depending on the design.

4. Material:

• Material: The gear is usually made from durable materials such as:
  • Plastic (e.g., Nylon, POM): Lightweight, suitable for low-torque applications, and commonly used in toy robots, printers, etc.
  • Metal (e.g., Steel, Brass, or Aluminum): Stronger materials are used in high-torque or industrial applications where durability is important.

5. Gear Type:

• Spur Gear: Typically, a gear with 25 teeth and a 6mm bore would be a spur gear, where the teeth are straight and parallel to the axis of rotation. Spur gears are commonly used for transmitting motion between parallel shafts.

6. Outside Diameter:

• Outside Diameter (OD): The outside diameter is determined by the number of teeth and the module. This can be calculated based on the formula: OD=(Number of Teeth)×(Module)OD = (Number of Teeth) imes (Module) For example, if the module is 1.0, the OD would be: OD=25×1.0=25 mmOD = 25 imes 1.0 = 25 , ext{mm}

7. Shaft Mounting:

• Mounting Type: The 6mm bore allows for mounting the gear onto a 6mm shaft. It may also feature a set screw or keyway for secure attachment to the shaft to prevent slippage.

8. Applications:

• Robotics: Used in robotic gearboxes for transmitting power between motors and wheels.
• Motorized Systems: Commonly found in motorized toys, fans, or smaller machinery.
• Transmission Systems: Helps in adjusting speed and torque in various mechanical systems.
• 3D Printers: Often found in the drivetrain mechanisms of 3D printers.
• Model Making: Used in hobby projects, especially in model cars, trains, and other mechanical models.

9. Tooth Profile:

• Straight Teeth: Spur gears with straight teeth are the most common in many applications due to their simplicity, effectiveness, and ease of manufacture.
• Pressure Angle: The pressure angle, typically 20° or 14.5°, defines the angle between the line of action (the force line) and the direction of motion.

Benefits of Using a 25 Teeth Gear with 6mm Bore:

1. Precision Power Transmission: The gear can efficiently transmit rotational motion with little loss of energy.
2. Versatility: Suitable for various applications, including hobby robotics, educational projects, and mechanical systems.
3. Compact Size: Ideal for space-constrained applications where smaller gears are needed.
4. Durable: When made from high-quality materials, such as POM or steel, the gear can withstand moderate to high amounts of torque.

Example Applications:

1. Robotics: Used in wheel-drive systems or motorized arms, where the gear transmits power from a motor to wheels or other components.
2. Electric Cars: Used in the gearboxes of small electric vehicles or model cars.
3. Automated Systems: In systems that require precise motion control, such as conveyor belts or sorting machines.

Conclusion:

The 25 Teeth Gear with a 6mm bore is a widely used mechanical component for transferring motion and torque between rotating shafts. It is often made of durable materials such as plastic or metal and is designed for a variety of applications, including robotics, automation, and mechanical projects. When choosing a gear, it is important to ensure that the module, material, and number of teeth match your specific requirements to achieve optimal performance.
