3-Stage Gearbox (2 UDL 2.2kW And 1 WPDS 120)

The 3-Stage Gearbox (2 UDL 2.2kW And 1 WPDS 120) is a gearbox line combined from a 2-stage gearbox and equipped with a mechanical speed variator (UDL) to form a 3-stage gearbox transmission system capable of heavy-duty operation and maintaining high performance over long periods. With a rigid cast iron housing, precisely arranged bearing shafts, and long service life, the product is suitable for various industrial applications requiring high torque and low speed.

General Design of the 3-Stage Gearbox (2 UDL 2.2kW And 1 WPDS 120)

The 3-Stage Gearbox (2 UDL 2.2kW And 1 WPDS 120) features a powerful, stable, and durable multi-stage transmission system. The outer housing is solidly cast from cast iron or aluminum alloy, providing excellent load-bearing capacity, reducing vibration, and protecting the internal mechanism. The input and output shafts, flanges, and mounting feet are reasonably arranged for easy installation and connection with motors or other industrial equipment. The optimized oil seal, bearing, and cooling fin system helps minimize friction, ensures smooth operation, and enhances the lifespan of the entire drive assembly.

Detailed Structure of the 3-Stage Gearbox (2 UDL 2.2kW And 1 WPDS 120)

The 3-Stage Gearbox (2 UDL 2.2kW And 1 WPDS 120) is formed by combining a 2.2kW 3Hp motor speed variator with a UDL 2.2kW – WPDS 120 2-stage gearbox to create a flexible transmission system with the following structure:

Structure of the speed variator:

• Friction disc – cone disc assembly: Changes contact to steplessly adjust output speed, ensuring smooth and stable operation.
• Drive shaft: The input shaft receives power from the motor; the output shaft transmits the adjusted speed to the system.
• Adjustment handwheel mechanism: A knob or lever applies pressure to the discs, allowing flexible speed increase and decrease.
• Protective housing & bearings: Cast iron/aluminum housing protects the internal mechanism; bearings and oil seals reduce friction, minimize vibration, and extend equipment lifespan.

Structure of the UDL 2.2kW – WPDS 120 2-stage gearbox:

• Stage 1: UDL mechanical speed variator featuring a friction disc mechanism for smooth, jerk-free speed control, with a durable, lightweight aluminum housing for rapid heat dissipation
• Stage 2: Worm gearbox, specifically the WPDS 120 worm gearbox, operating smoothly and durably, creating low output speed and high torque, with hollow or solid output shaft configurations depending on setup. Compact design, easy to integrate into various machinery
• Includes flexible couplings linking the stages, an intermediate shaft mounted on high-quality bearings, and a sturdy base to maintain concentricity, reduce vibration, and enhance overall system durability.
• Comprises driving and driven friction discs, working radius adjustment rollers, and a lever/screw speed adjustment mechanism. The input shaft connects directly to the motor, creating the first reduction stage and providing continuous speed variation.
• Comprises a hardened steel worm shaft, wear-resistant copper alloy worm gear, heavy-duty bearings, and a rigid cast iron housing. This stage provides deep reduction, a 90° change in rotation direction, and high output torque.
