3-Stage Gearbox (2 UDL 2.2kW and 1 WPDA 120)

3-Stage Gearbox (2 UDL Variators 2.2kW And 1 WPDA Worm Gearbox 120) is a gearbox line combined with a 2-stage gearbox and equipped with an additional mechanical speed variator (UDL) to form a 3-stage gearbox drive system, delivering flexible speed adjustment and deep reduction within a single assembly. With a compact design, sturdy materials, and excellent compatibility with various machines, the product effectively meets modern transmission demands.

General design of 3-Stage Gearbox (2 UDL Variators 2.2kW And 1 WPDA Worm Gearbox 120)

The 3-Stage Gearbox (2 UDL Variators 2.2kW And 1 WPDA Worm Gearbox 120) features a monolithic cast iron or aluminum alloy housing, protecting all internal mechanisms and minimizing vibration during operation. Flanges and mounting tabs are arranged scientifically for easy installation, while the protective cover and oil chamber maintain stable lubricating oil, reducing friction and extending equipment life. Reasonably designed cooling fins ensure efficient heat dissipation and smooth operation for the entire drive assembly.

Detailed structure of 3-Stage Gearbox (2 UDL Variators 2.2kW And 1 WPDA Worm Gearbox 120)

The 3-Stage Gearbox (2 UDL Variators 2.2kW And 1 WPDA Worm Gearbox 120) is formed by combining a 2.2kW 3Hp mechanical speed variator with a UDL 2.2kW – WPDA 120 2-stage gearbox to create a stable and flexible multi-stage drive assembly with the following structure:

Speed variator structure:

• Speed control disk system: Cone disks and friction disks are designed to continuously change the transmission ratio, allowing the motor to output flexible speeds.
• Main drive shaft: The input shaft receives power from the motor; the output shaft stably transmits the adjusted speed to the system.
• Force adjustment mechanism: A handwheel or knob adjusts the clamping force on the disks, controlling fast and slow speeds as needed.
• Housing & bearings: Metal housing protects the mechanism; ball bearings and oil seals ensure smooth motion, reduce vibration, and enhance equipment lifespan.

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

• Stage 1: The UDL mechanical speed variator uses a planetary gear mechanism to flexibly change the output shaft speed.
• Stage 2: The worm gearbox, specifically the WPDA 120 worm gearbox, ensures smooth, stable system operation suitable for various load modes.
• Active – passive friction disks, roller assemblies that change the working radius, and a lever/speed adjustment screw mechanism. The input shaft connects directly to the motor, creating the initial reduction stage and continuous speed adjustment.
• Hardened steel worm shaft, wear-resistant bronze alloy worm wheel, sturdy thick cast iron housing, and heavy-duty bearing system. This stage handles deep reduction, a 90° change in rotation direction, and generates strong output torque.
• Includes flexible couplings between stages, an intermediate shaft mounted on high-quality ball bearings, and a sturdy base to maintain concentricity, reduce vibration, and increase durability for the entire drive assembly.
