Material Compatibility and Performance Customisable Spur Gears in Gear Transmission Applications

1.Spur Gear Description

From a material compatibility perspective, a spur gear is a customisable transmission component that

can be manufactured from various materials according to operational requirements, achieving optimal performance

through the alignment of material properties with the application scenario.

2.Key Features

Characterised by an exceptionally broad material selection range, enabling targeted material choice based on factors

such as load, rotational speed, and environment. Advantages include balancing cost and performance – for instance,

employing plastics in light-load scenarios to reduce costs, or using alloy steel in heavy-duty applications to enhance strength.

Additionally, materials exhibit good machinability, facilitating diverse processing techniques.

3.Working Principle

Material types are determined by load classification (light, medium, heavy) and environmental conditions.

For instance, stainless steel spur gears are selected for corrosion resistance in food machinery,

while quenched and tempered alloy steel spur gears are chosen for wear resistance in construction equipment.

Mechanical properties (hardness, strength, toughness) are matched to transmission requirements to prevent failure

such as fracture or excessive wear during operation.

4.Applications

Stainless steel spur gears in food processing machinery; titanium alloy micro spur gears in medical devices;

heat-resistant steel spur gears in high-temperature kiln drives; plastic spur gears in toys and small household appliances.
