Discover more about the Mitre Gears range.

Mitre gears are specialised gears designed to transmit power between intersecting shafts at a precise 90-degree angle with a 1:1 speed ratio. Unlike other precision gears, which can operate at various angles and gear ratios, mitre gears are exclusively used when equal-speed transmission is required.

These gears are commonly used in applications such as mechanical drives, robotics, automotive systems and industrial machinery where precise angular power transmission is essential.

How Do Mitre Gears Work?

Mitre gears operate by meshing two identical gears with conically shaped teeth, enabling efficient torque transfer between perpendicular shafts. Their symmetrical design ensures that both gears rotate at the same speed without altering the rotational speed of the output shaft. This makes them ideal for applications requiring compact, efficient and precise right-angle power transmission without speed variation.

Materials Mitre Gears Are Made From

Accu's range of precision mitre gears are available in a range of materials to suit different performance requirements:

Steel: Offers high strength and durability for heavy-duty applications.

Stainless Steel: Provides excellent corrosion resistance, making it suitable for harsh environments.

POM (Polyoxymethylene): A lightweight and low-friction material ideal for applications requiring quiet and smooth operation.

Optional Induction Hardened Teeth: Increases wear resistance and prolongs gear life in demanding conditions.

Optional Black Oxide Finish: Ensures compatibility with different environmental and performance requirements.

Sizes and Types of Mitre Gears Available

Our selection of mitre gears comes in various specifications to accommodate diverse rotary movement needs. They are available with a pitch ranging from 1MOD to 4MOD, tooth counts between 16 and 30 and pitch circle diameters varying from 10mm to 90mm, offering flexibility in design.

FAQs

Q: What is the difference between a mitre vs bevel gear?

A: Mitre gears are a specific type of bevel gear designed to transmit motion at a 90-degree angle with a 1:1 ratio. In contrast, bevel gears can operate at different angles and ratios, providing more flexibility in power transmission.

Q: Where are mitre gears commonly used?

A: They are used in mechanical systems where right-angle power transmission is necessary, such as robotics, conveyor systems and precision engineering equipment.

Q: What are the benefits of using mitre gears?

A: They provide efficient 90-degree power transfer, minimal backlash and high precision in compact assemblies, making them ideal for space-constrained applications.

Q: What lubrication is recommended for mitre gears?

A: Lubrication depends on the material and application, but common choices include synthetic gear oils and grease for metallic materials. We only recommend dry lubricants for low-friction polymer gears.
