Spur Gears

Stainless Steel Spur Gears

Spur gears are used in mechanical applications to increase or decrease the speed of a device or multiply torque by transmitting motion and power from one shaft to another through a series of mated gears. Spur gears are one of the most popular types of precision cylindrical gears. These gears feature a simple design of straight, parallel teeth positioned around the circumference of a cylinder body with a central bore that fits over a shaft. In many variants, the gear is machined with a hub that thickens the gear body around the bore without changing the gear face. The central bore can also be broached to allow the spur gear to fit onto a spline or keyed shaft.

Stainless steel spur gear, also known as straight-cut gears, is a standard gear used in various applications. They are designed to transmit large amounts of power by placing them on parallel shafts which rotate in opposite directions. The stainless steel spur gear has a precise machining process, is heat-treated, and can meet 6-grade precision gear stands.

The producing character of stainless steel spur gears:

1. Gear size: the most oversized diameter is 1500mm;

2. Material: Most common steel is high-strength steel 20CrMnTi. Others can be steel C45, stainless steel, high strength steel, copper, aluminum, plastic, POM, etc;

3. Gear module: 0.3-8 (pitch from 0.942-25.12mm, DP 3.175-85);

4. Surface: zinc (galvanized), black, chromium plating, nickel plating, quenching, tempering, etc.

5. Quality: stable and high, grade 7 for without teeth grinding, grade 6 after grinding, grade 5 for precise grinding.

Prices for the above quality are very competitive for us.

6. Heat treatment: teeth can be hardened to HRC 55-63.

The quality character of stainless steel spur gears:

1. Stable transmission and low noise;

2. Effectively avoid standard tolerance based on high precision;

3. The teeth can be ground to grade 6 and grade 5 quality;

4. The bore will be polished to smooth and high precision;
