Double gears are specialized gears designed to transmit motion between two parallel shafts in mechanical systems. These gears feature two sets of teeth on the same gear wheel, which allows them to mesh with two separate gears at the same time. They are used in a variety of applications, including machines that require precise speed reduction or increase, and systems that involve two separate axes. Understanding the materials, sizes, and features of double gears is essential for selecting the right type for your mechanical systems.
Standard Materials for Double Gears
Double gears are available in a variety of materials, each chosen for its specific properties such as strength, durability, and resistance to wear. The standard materials commonly used for manufacturing double gears include:
- Steel (En32): This steel grade offers a balance between strength, toughness, and wear resistance, making it ideal for most mechanical applications requiring a durable gear.
- Stainless Steel (En58): Stainless steel is chosen for its corrosion resistance, making it suitable for environments where moisture or chemicals are present, or for systems that operate in harsh conditions.
In addition to these standard materials, double gears can also be manufactured from:
- Brass: Known for its low friction properties, brass is often used in low-load, low-speed applications where smooth operation is required.
- Tufnol: A high-performance composite material used in certain specialized applications where lightweight and wear resistance are critical.
- Delrin: A durable thermoplastic that offers high wear resistance and low friction, making it ideal for quieter, smoother gear operation.
Sizes and Specifications
Double gears are available in various sizes and configurations to suit different applications. The following are the standard sizes and specifications for double gears:
- Outside Diameter:
- Max: 300mm
- Min: 5mm
- Pitches:
- 0.25mod – 3mod
- 96DP – 8DP
- Pressure Angle: 20°
These dimensions allow for flexibility in selecting gears that match the specific requirements of your system, whether you are dealing with large industrial equipment or small precision machinery.
Applications of Double Gears
Double gears are commonly used in gear systems where the rotation of two shafts needs to be synchronized, or in cases where a compound gear train is required to transmit torque across two axes. Some typical applications of double gears include:
- Mechanical clocks: Double gears are used to adjust the speed of the movement and synchronize multiple gears.
- Automotive gearboxes: In some gear systems, double gears are used for smoother power transfer and more efficient gear ratios.
- Industrial machinery: Double gears are often employed in conveyor systems, robotics, and other machinery requiring efficient torque transmission between parallel shafts.
Custom Manufacturing
If your application requires specific configurations or materials, double gears can be manufactured to non-standard specifications. Whether you need unique gear ratios, materials, or dimensions, gears can be produced based on your drawings or Technical Request Form.
Conclusion
Double gears are integral components for precise motion transmission in mechanical systems, offering efficient power transfer between parallel shafts. With materials such as Steel (En32), Stainless Steel (En58), Brass, Tufnol, and Delrin, double gears can be tailored to meet the needs of various industries and applications. Whether you require gears with specific pitches (from 0.25mod to 3mod) or unique outside diameters (ranging from 5mm to 300mm), double gears can be manufactured to exact specifications. Choose double gears for reliable, efficient, and precise performance in your mechanical designs.
