Technical Definition & Core Assembly

A canonical Speed Reducer/Gearbox is characterized by the integration of Gear Set and Housing/Casing. In industrial production environments, manufacturers listed on CNFX commonly emphasize Cast Iron construction to support stable, high-cycle operation across diverse manufacturing scenarios.

A mechanical device that reduces the input speed from a motor while increasing torque output for conveyor systems.

Product Specifications

Technical details and manufacturing context for Speed Reducer/Gearbox

Definition
A critical component of the Workpiece Conveyor system that precisely controls the speed and torque transmitted to the conveyor mechanism, ensuring smooth, controlled movement of workpieces along the production line with optimal power efficiency.
Working Principle
Utilizes a system of gears (such as helical, bevel, or worm gears) arranged in a housing to achieve a specific gear ratio. The input shaft, connected to the motor, rotates at high speed, while the meshing gears reduce this rotational speed at the output shaft, proportionally increasing the available torque for driving the conveyor.
Common Materials
Cast Iron, Alloy Steel
Technical Parameters
  • Rated output torque capacity (Nm) Per Request
Components / BOM
  • Gear Set
    Transmits and modifies rotational speed and torque through meshing teeth.
    Material: Case-Hardened Alloy Steel
  • Housing/Casing Part
    Encloses and supports the gear set and bearings, contains lubricant, and provides mounting points.
    Material: Cast Iron or Aluminum Alloy
  • Input/Output Shafts Part
    Transmit rotational force into and out of the gearbox, connecting to the motor and driven load (conveyor).
    Material: Carbon Steel or Alloy Steel
  • Bearings
    Support the rotating shafts and gears, minimizing friction and maintaining alignment.
    Material: Bearing Steel
