Precision Gears.

What are Precision Gears?

Gears are fundamental mechanical components used for transmitting torque and rotation in countless engineering projects. A gear's physical attributes, such as its teeth, pitch and diameter all play a crucial role in how it interacts with other gears or rotary components such as belts and leadscrews.

Accu's range of precision gears is precisely engineered to exact specifications for smooth, reliable operation. From the meshing of teeth with minimal friction, ensuring efficient energy transfer to minimal tolerances within the bore. This intricate synchronisation between mechanical gears is central to systems ranging from simple mechanical clocks to complex industrial machinery.

How Gears Work

Gears function by interlocking their teeth with those of another gear effectively transmitting power and motion at high speeds. The versatility of gears spans various industries, including robotics, aerospace, and manufacturing.

For instance, in a robotics gear design, gears help to convert and direct the rotational motion from a motor to other larger gears and sprockets, eventually leading to movement and adapting to the controller's input. This is often known as gears meshing together. Precision gears are vital in robotics for precise motion control, or in aerospace devices where the most precise accuracy is paramount.

The real-life applications of gears and gear trains are as diverse as they are crucial, providing both power and precision in everyday items such as vehicles, 3d printers and even your electricity meter.

What Are Gears Made Of?

The choice of material is pivotal in gear manufacturing. We offer gears machined in Brass, Steel, Stainless Steel, and Aluminum, each bringing unique advantages.

Brass gears, known for their smoothness, are ideal in almost all applications. Steel gears offer unmatched strength, perfect for heavy-duty environments. Stainless Steel gears are the go-to for projects requiring some sort of corrosion resistance, and Aluminum gears provide a lightweight yet robust solution for various applications.

Understanding what are gears made of helps in selecting the right material for your next project.

Size, Type and Finishes

Our precision gears offer various numbers of teeth ranging from 10 to 120 and vary with pitch circle diameters stretching from 4.2mm to 100mm. Bore diameters vary between 4mm and 20mm, catering to diverse requirements. We offer spur gears, anti-backlash spur gears, and adjustable backlash control spur gears, each designed for specific applications. Additionally, Our precision gears can be spaced and calibrated using supporting components such as spacers or shim washers.

Finally, if you're unable to find the precise gear design you need for your project, Accu prides itself on being able to custom manufacture precision gears, ensuring that the gear perfectly fits your unique requirements.

FAQs

Q: What does a gear do?

A: A gear is a small circular component with interlocking teeth essential in transmitting rotational force and motion between different parts of a machine. They adjust the direction, speed, and torque of movement, playing a critical role in many mechanical engineering systems. Learn more about gears by delving into our "What Are Gears?" article.

Q: What is the standard for gear accuracy?

A: Gear accuracy is typically defined by international standards such as ISO. These standards categorise gears based on their precision levels, considering factors like tooth profile and pitch deviations.

Q: How do you check gear accuracy?

A: Gear accuracy is measured using specialised tools and techniques like gear testers, micrometres, and CMMs. These methods assess various parameters including pitch, profile, and tooth-to-tooth errors to ensure conformity with design specifications.

Q: What is a tooth-to-tooth error in gears?

A: Tooth-to-tooth error refers to the variation in spacing between adjacent teeth on a gear. This is a critical parameter in gear design and manufacturing, as it affects the smoothness and noise of gear operation.

Q: What is backlash error in gears?

A: Backlash in gears is the small gap between meshing gear teeth, necessary for free movement. Excessive backlash can lead to gear wear and noise, while insufficient backlash may cause overheating and seizing. For a greater understanding of backlash, give our article "What Is Backlash?" a read.
