Spur Gear
China Spur Gear OEM & Contract Manufacturer Shanghai DE Industrial Co., LTD. provides top quality Spur Gear OEM services for industries.

1. Product Features
Spur gear (Single) usually having ratio between 1:1 and 1:6 pitch line velocity can be up to 25m/s. Spur gears show an best efficiency. Spur gears are made from hard material compared to the other wheel gears, spur gear contains more teeth compare to others gears.

2. Manufacturing Capacity/Size
Max module 25
Pressure angle 30, 20, 14.5 Degree
Max PCD Φ 2000mm
Min PCD Φ50mm
Max Gear Face Width 500mm
Accuracy DIN 6-8

3. Functional Analysis
The following application requirements should be considered with the workload and environment of the gear set in mind.
• Power, velocity and torque consistency and output peaks of the gear drive so the gear meets mechanical gears requirements. Spur gears' design constraints limit their ability to transfer energy at high speeds and torques.
• Inertia of the gear through acceleration and deceleration. Heavier gears can be harder to stop or reverse.
• Precision requirement of gear, including gear pitch, shaft diameter, pressure angle and tooth layout.
• Gear lubrication requirements. Some gears require lubrication for smooth, temperate operation.
• Mounting requirements. Application may limit the gear's shaft positioning.
• Noise limitation. Commercial applications may value a smooth, quietly meshing gear. Spur gears are particularly noisy in operation.
• Corrosive environments. Gears exposed to weather or chemicals should be especially hardened or protected.
• Temperature exposure. Some gears may warp or become brittle in the face of extreme temperatures.
• Vibration and shock resistance. Heavy machine loads or backlash, the deliberate surplus space in the circular pitch, may jostle gearing.
• Operation disruption resistance. It may be necessary for some gear sets to function despite missing teeth or misalignment.

4. Materials
