Miter gears, also known as bevel gears, are a special type of bevel gear designed to mesh at a 90-degree angle, transmitting power between intersecting shafts. These gears are alternatively referred to as bevel gears or right-angle gears.
Miter Gear
Miter gears have straight teeth and a conical profile for transmitting motion at a right angle without changing shaft speed or torque. They’re more efficient than spiral miter gears, which means they require less power to do the same work; however, they are noisier when run at high speeds and under heavy loads. Configure in pairs.
Spiral Miter Gear
Spiral miter gears have curved teeth that gradually engage and stay in contact longer than straight teeth so they handle heavier loads at higher speeds. They run smoother and quieter than standard miter gears but are not as efficient, which means they require more power to do the same work. Furnished as a pair, they transmit motion at a right angle while maintaining shaft speed and torque.
Manufacturing Process:
- Gear Cutting: Miter gears are produced through precision gear cutting processes, often using methods like hobbing or milling.
- Heat Treatment: Heat treatment is applied to enhance the hardness and durability of the gears, ensuring optimal performance.
- Surface Finishing: Precision grinding or lapping may be employed for achieving precise tooth surfaces and ensuring smooth gear operation.
Materials: Miter gears are commonly manufactured from materials such as alloy steel, stainless steel, and other specialized alloys. Material selection is influenced by factors such as load capacity, wear resistance, and environmental conditions.
Quality Requirements: High-precision manufacturing is crucial for miter gears to ensure accurate tooth profiles, minimal backlash, and smooth meshing. Rigorous quality control measures are applied to meet industry standards.
