Product Introduction
The WPDA 135 worm gearbox is a medium-to-heavy load transmission solution, designed with a motor connection flange and a downward input shaft, increasing torsional load capacity and ensuring stable operation in industrial environments. The equipment is suitable for high-grade concrete mixers, coal conveyors, and marine anchor winches.
⚡Thanh Thai Motor offers a 24-month warranty, nationwide wholesale and retail, and 2D drawing consultation.
The WPDA 135 worm gearbox is a specialized mechanical transmission device, widely applied in industrial production lines thanks to its efficient speed reduction and high torque transmission capability. With a right-angle input-output shaft configuration, the gearbox is particularly suited for limited installation systems or those requiring changes in transmission direction. This is the optimal choice for businesses requiring a durable, stable, smoothly operated transmission solution with minimized maintenance costs.
The WPDA 135 worm gearbox is designed with a sturdy structure, and the housing is made of thick solid cast iron, providing high load-bearing capacity and resistance to deformation during continuous operation under heavy-duty conditions. The outer surface is coated with high-grade electrostatic paint, preventing oxidation and corrosion, making it suitable for production environments with dust, high humidity, or mild chemicals.
The input and output shaft structures are arranged at a 90-degree right angle, facilitating easy changes in transmission direction without taking up much installation space. Worm gearboxes are typically directly coupled with an electric motor to form a high-capacity gear motor combination, optimizing torque transmission efficiency and reducing output rotation speed.

The WPDA 135 worm gearbox features a precisely machined worm and worm gear transmission structure, ensuring efficiency and durability:

To ensure the worm gearbox operates durably, reduces friction, and minimizes damage during operation, proper oil replenishment is extremely important.
Step 1: Drain old oil (if already used)
Before changing the oil, completely disconnect the power source to ensure safety. Then open the drain plug to let all the old oil flow out. Once the oil has been completely drained, tighten the drain plug securely. For new equipment, this step can be skipped.
Step 2: Add new oil
Open the oil filling plug and slowly pour in new oil. During the filling process, observe the oil sight glass to monitor the oil level. When the oil reaches about the middle of the glass, stop to avoid overfilling.
Step 3: Completion and inspection
After filling with oil, tightly close the oil filling plug and recheck all assembly positions. At the same time, thoroughly clean any excess oil on the surface of the gearbox before putting the equipment into operation.
The WPDA worm gearbox features a sturdy cast iron housing, operates smoothly, and is suitable for various industrial transmission systems. Through the instruction video of the gearbox by Thanh Thai Motor, you will clearly understand the process of adding oil, installation, and using the equipment effectively. In addition, follow more summary videos to update many useful tips and technical knowledge.
