Descriptions of EPRV Worm Gearbox

EPRV worm gearbox adopts a "square box" structure and adopts a high-quality aluminum alloy casting box. It has a beautiful appearance, small volume, fast heat dissipation, and flexible installation. The whole machine adopts high-quality bearing transmission parts and seals to ensure durability and no leakage. More importantly, the worm gear pair adopts precision machining and precision meshing detection to ensure the balance of machine transmission, low-temperature rise, low noise, high efficiency, and long service life. In addition, the input and output components of the EPRV worm gearbox are precision machined, and the whole machine is rust-free and high-grade. Equipped with a worm gear reducer, the output speed can be adjusted under the load to achieve step-less variable speed output. The manufacturing standard of the EPRV worm gearbox is based on the national standard GBl0085-88 cylindrical worm to ensure superior performance.

Advantages of EPRV Worm Gearbox

  • Quick stop function

For a general gear reducer, it takes 5 to 10 seconds for the stop time, but for the EPRV series, the stop state could be reached in only 2 to 5 seconds.

  • High safety

The EPRV worm gearbox adopts a different way compared to the traditional one in that it doesn’t need the sprocket and pulley. What’s more, the transmission structure is not exposed, so the injuries of the operator could be reduced.

  • Good protection

Grade IP55 is adopted, which has good isolation for dust and moisture.

  • Excellent thermal conductivity

The EPRV worm gear is equipped with cooling ribs so that the body has excellent thermal conductivity and low temperature-rising.

  • Long service life

The worm gearbox operates smoothly with low noise, which is suitable for long-term contact work in harsh environments.


The EPRV worm gearboxes are widely used in the automation industry, industrial robots, aerospace, CNC machine tools, metallurgical mining, beer and beverage, tobacco light industry, environmental engineering, warehousing logistics, plastics machinery, lifting transport, three-dimensional parking, automobile manufacturing, textiles, food, ceramics, and other fields.

Operating conditions

  1. The EPRV worm gearbox has good versatility and is used with various mechanical equipment.
  2. A larger transmission ratio could be achieved by a single-stage transmission. Most types of speed reducers have a good self-locking ability, and mechanical devices with braking requirements can save braking devices.
  3. The meshing friction loss of the worm screw teeth and the surface of the worm gear tooth is large, so the transmission efficiency should be lower than that of the gear.
  4. The EPRV worm gearbox has high requirements for lubrication and cooling.


  1. Before use, please confirm that the turbine reducer and the mechanical safety supporting strength are within the safe range of the performance parameters of the reducer.
  2. The turbine gearbox has been filled with WA460 lubricant at the factory. After 400 hours of operation, the lubricant should be replaced. The oil change cycle is about 4000 hours later.
  3. The reducer casing body should retain enough lubricating oil, and regularly check the amount of oil.
  4. Avoid damage to the gearbox caused by sharp shaft damage caused by sharp equipment
  5. Check the direction of rotation before installing the machine.
  6. Set a safety cover, etc., in the rotation area.
