FAQ Spur Gears

Question: What are Spur Gears?: Answer: Spur gears are the most common type of gear used in mechanical systems. They have straight teeth and are mounted on parallel shafts. These gears are used to transmit power between two shafts and are known for their simplicity, efficiency, and ability to handle high torque.
Question: What are some common terms used in spur gear design?: Answer: • Diametral pitch: The number of teeth per inch of pitch diameter.
• Pitch diameter: The diameter of the pitch circle, which is the circle that passes through the midpoints of the teeth.
• Backlash: The clearance between the teeth of mating gears.
• Pressure angle: The angle between the line of action and the common tangent to the pitch circles of the gears.
Question: Can Spur Gears be customized?: Answer: Yes, spur gears can be customized based on:
• Number of teeth
• Material type
• Pressure angle
• Gear width and diameter
• Surface treatments (heat treatment, coating)
Question: How do you choose the right Spur Gear for an application?: Answer: To choose the right spur gear:
• Determine the required gear ratio.
• Consider the torque and load capacity.
• Select the appropriate material based on the operating environment.
• Ensure compatibility with the shaft size and alignment.
Question: How do you calculate the gear ratio of Spur Gears?: Answer: The gear ratio is calculated by dividing the number of teeth on the driven gear by the number of teeth on the driving gear. The formula is:
Gear Ratio = Number of Teeth on Driven Gear ÷ Number of Teeth on Driving Gear
A higher gear ratio results in higher torque but lower speed.
