30kW To 400kW Extrusion Gearbox For Brick And Tile Machinery

Optimized Sealing Structure

The dedicated extrusion gearbox for brick and tile machinery is the core power transmission component of both vacuum and non-vacuum brick machines, commonly known as the "extruder reducer" or "brick machine main shaft."

Product Overview

Positioned between the motor and the extrusion screw, its primary function is to convert the high-speed rotation of the motor into the low-speed, ultra-high torque rotational movement required by the extrusion screw. It operates under conditions of continuously enduring immense back pressure (from the compressed clay) and severe shock loads, in a typically dusty and humid environment. Its performance and reliability directly determine the quality of green bricks, production output, and the overall machine's operational stability.

Key Advantages

Exceptional Load Capacity & Torque Output: Features heavy-duty design with high-strength alloy steel gears and shafts, carburizing quenching, and precision grinding for maximum bending and contact fatigue strength.
Superior Shock Resistance: Designed to handle instantaneous severe shocks with high service factor and overload capacity, featuring rigid housing that effectively absorbs and dampens impacts.
Optimized Sealing Structure: Utilizes multiple sealing combinations (labyrinth seals, lip seals, air purge seals) to prevent contaminant ingress and lubricant leakage in humid, dusty environments.
High Transmission Efficiency & Thermal Balance: Precision gear machining and optimized bearing arrangements ensure high efficiency, with cooling devices on larger models to maintain optimal operating temperatures.
Compact Structure & Reliable Connection: Designed for integration with host machines, featuring heavy-duty couplings or direct flange connections for reliable alignment and power transmission.
Ease of Maintenance: Accessible inspection covers, drain plugs, and lifting points facilitate easy daily oil level checks and routine maintenance.

Technical Parameters

Parameter	Specification
Power Range	30kW to 400kW+
Output Torque	Extremely high - tens of thousands to hundreds of thousands of N.m
Output Speed	Very low - 10-25 rpm
Reduction Ratio	20:1 to 50:1 or higher

Applications

Vacuum Brick Machines: Core equipment for producing high-quality hollow bricks, perforated bricks, and insulating blocks
Non-Vacuum Brick Machines: For producing solid standard bricks and paving bricks
Double-Stage Vacuum Extruders: Both first stage (mixing/extrusion) and second stage (vacuum extrusion) applications
Other Extrusion Equipment: Clay extrusion processes in pottery, refractories, and ceramics industries
