Understanding Spur Gears: The Backbone of Industrial Power Transmission

Wenlio Spur Gear Grinding

Manufacturing company since 2004

Spur gears are widely used in industrial machinery because they transfer power efficiently between parallel shafts. Their straight tooth design makes them suitable for reducers, automation equipment, agricultural machinery, and many mechanical drive systems.

Although the structure is simple, a reliable spur gear still depends on accurate tooth profile, proper material, heat treatment, grinding quality, and inspection control.

Wenlio manufactures custom spur gears based on drawings, samples, or application requirements, supporting machining, heat treatment, gear grinding, and quality inspection for stable industrial transmission performance.

Quick View of Spur Gear

This short video gives a clear visual reference for spur gears, helping buyers recognize the straight tooth form, drawing features, and parallel-shaft transmission movement.

Spur gears are widely used in simple and efficient mechanical transmission systems. Wenlio can manufacture custom spur gears based on drawings, samples, module, tooth count, material, heat treatment, accuracy grade, and order quantity.

With the gear type confirmed, Wenlio can review the technical details needed for machining, heat treatment, inspection, and stable delivery.

Essential Technical Parameters

    • Pitch circle: The theoretical circle where gears mesh and transfer motion
    • Diametral pitch: Number of teeth per inch of pitch diameter
    • Module: Metric measurement of tooth size and spacing
    • Pressure angle: Angle determining load distribution and gear strength
    • Addendum & dedendum: Tooth height above and below pitch circle

Common pressure angles include 14.5ยฐ for smooth, quiet operation and 20ยฐ for enhanced tooth strength and higher load capacity, each influencing performance characteristics and noise levels.

Common Spur Gear Manufacturing Process

For spur gears, hobbing is the most common and cost-effective method for external gears in medium to large quantities.
For internal gears or shoulder-limited designs, shaping or broaching is required.
If high accuracy or low noise is required, shaving or grinding will be applied after cutting.

Disc-Type Gear Milling Cutter

Gear Milling

Advantages:

      • Low equipment requirement
      • Fast changeover, suitable for prototypes and samples

Disadvantages:

      • Low accuracy (typically โ‰ค DIN 9โ€“10)
      • Low efficiency, not suitable for mass production
Gear shaving

Gear Shaving

Advantages:

      • Significantly improves noise performance and meshing quality
      • Lower cost compared to gear grinding

Disadvantages:

      • Only applicable before heat treatment
      • Not suitable for hardened gears
Gear Hobbing

CNC Gear Hobbing

Advantages:

      • Stable accuracy (DIN 6โ€“8)
      • Applicable to nearly 90% of external spur gears

Disadvantages:

      • Not suitable for internal gears
      • Limited for gears with shoulder or step structures
CNC gear shaping

CNC Gear Shaping

Advantages:

      • Suitable for internal gears
      • Capable of cutting gears close to shoulders or steps

Disadvantages:

      • Lower efficiency compared to hobbing
      • Relatively shorter tool life
