3-Stage Gearbox (2 UDL 1.5kW And 1 WPDA 80)

The 3-Stage Gearbox (2 UDL 1.5kW And 1 WPDA 80) is a gearbox line combined by a mechanical speed variator (UDL) and a 2-stage gearbox to form a 3-stage gearbox that operates stably, powerfully, and saves electricity. At the final stage, it generates strong torque and low but stable speed, meeting the needs of equipment requiring high traction during long-term operation.

Overall design of the 3-Stage Gearbox (2 UDL 1.5kW And 1 WPDA 80)

The 3-Stage Gearbox (2 UDL 1.5kW And 1 WPDA 80) features multi-stage transmission with wide speed adjustment capability and large output torque. The outer casing is solidly designed with cast iron or cast aluminum, optimizing rigidity and anti-vibration capability during operation. The joint surfaces, flanges, and shafts are scientifically arranged, supporting fast installation and compatibility with various motor lines. Cooling fins, high-end oil seals, and bearings are technically standardized to keep the equipment operating stably, durably, and minimizing energy loss due to friction.

Detailed structure of the 3-Stage Gearbox (2 UDL 1.5kW And 1 WPDA 80)

The 3-Stage Gearbox (2 UDL 1.5kW And 1 WPDA 80) is formed by a 1.5kW 2Hp motor speed variator combined with a UDL 1.5kW – WPDA 80 2-stage gearbox, creating a stable and flexible multi-stage transmission assembly with the following structure:

Structure of the variator:

• Speed change disk assembly: Consisting of cone disks and friction disks changing distance to provide a stepless speed range.
• Drive shaft pair: The input shaft receives power from the motor, and the output shaft outputs speed adjusted smoothly and stably.
• Mechanical adjustment unit: Handwheel/adjustment lever creates pressing force to change the disk assembly, allowing flexible speed increase and decrease.
• Casing & bearing system: Cast housing protects internal parts; bearings and oil seals keep movement smooth, reduce wear, and increase lifespan.

Structure of the UDL 1.5kW – WPDA 80 2-stage gearbox:

• Stage 1: The speed adjustment unit uses a cone disk – friction disk assembly to change the input transmission ratio, helping speed be continuously fine-tuned before moving to the reduction stage.
• Stage 2: The worm gearbox, specifically the WPDA 80 worm gearbox, is designed for deep reduction and increased torque. The hardened steel worm meshes with the alloy worm wheel, providing smooth transmission and noise reduction, with a sturdy cast iron casing offering good load capacity and efficient heat dissipation during continuous operation.
• Using a planetary gear mechanism for smooth speed change, the manual speed adjustment knob is easy to operate without shutting down the machine, undertaking the expansion of the speed range and stabilizing the input for the final reduction stage.
• Transmission stages connected by heavy-duty steel shafts and industrial bearings maintain stable transmission force, reduce friction, and limit vibration during operation.
