ISO 7 Grade Industrial Gearboxes and Material Handling Equipment with Transmission Spur Gears

1) Description of Internal Spur Gear

From an industrial application perspective, spur gears represent a standardised transmission component offering balanced performance and reliable durability. They achieve an excellent equilibrium between load-carrying capacity, manufacturing cost and dependability.

2) Working Principle

The meshing process employs a “line contact” transmission mechanism. Whilst it possesses certain limitations compared to more advanced gear designs, through judicious design considerations (such as profile modification) and material selection, it is entirely capable of meeting the power transmission requirements of the vast majority of industrial applications.

3) Characteristics of Internal Spur Gear

• Face-to-face meshing: Meshing occurs within a plane perpendicular to the axis.
• Modifiable profile: Meshing performance may be enhanced and impact reduced through techniques such as tooth-top profiling.
• Standardisation: Parameters including module and pressure angle are highly standardised, ensuring strong interchangeability.

4) Advantages of Internal Spur Gear

• Highly reliable with proven technology.
• Simple maintenance, straightforward to inspect and replace.
• Offers excellent load-bearing capacity and extended service life.

5) Application

Widely employed in various general-purpose industrial equipment:

• Low-speed stage gears in industrial gearboxes
• Material handling equipment such as cranes and conveyors
• Drive gears in automotive starter motors
