Worm Gear Reducer

Precision Structure and Excellent Heat Dissipation: Worm Gear Reducer's enclosure is made of high-quality die-cast aluminum alloy with ample cooling fins, offering excellent heat conduction and a large heat dissipation area, effectively extending its service life.

Quiet and Stable Operation: The Worm Gear Reducer uses a precision-ground, hardened-tooth-surface drive worm gear, resulting in low-noise and smooth operation, suitable for environments with high environmental requirements.

Robust and Durable: The worm gear is made of 20Cr steel, treated with carbonitriding, achieving a tooth surface hardness of HRC60; the worm wheel is made of special wear-resistant nickel bronze, offering strong wear resistance.

Omnidirectional Installation: Adaptable to all-around universal installation configurations, the terminal block and enclosure are integrally die-cast aluminum alloy, ensuring excellent sealing and preventing dust and leaks.

EFFICIENCY

Efficiency is an important indicator of a reducer, which depends on the design, manufacturing, and friction condition of the worm gear transmission pair. Due to the different friction characteristics of the gearbox in operation and at rest, the efficiency of the gearbox can be classified into dynamic efficiency and static efficiency.

LUBRICATION

RV REDUCER LUBRICATION VOLUME

-Lubrication volume for R V is related with mounting position of reducer.

-All stock of RV reducers are filled with WA320 lubrication according to B3 mounting position, if the mounting position is different from B3, a special indication is required.

LUBRICATION VOLUME (LITRE)

LUBRICATION VOLUME OF PC HELICAL GEAR MODULAR

-Lubrication of PC helical reduction modular is apart from lubrication of reducers. lubrication and the volume is irrespective with the mounting positions of PC.

-PC helical reduction modular is filled with lubrication WA680 before shipment

FAQ

Q1: Can this Worm Gear Reducer be used in highly corrosive environments?

A: Yes. The aluminum alloy body undergoes shot blasting and special anti-corrosion treatment, maintaining its silvery-white alloy appearance and resisting corrosion from organic solvents such as gasoline and xylene.

Q2: What type of oil is used in the Worm Gear Reducer at the factory?

A: RV Worm Gear Reducers are supplied with WA320 lubricating oil by default for the B3 installation orientation; PC helical gear modules are supplied with WA680 lubricating oil.

Q3: What should I do if my installation method is not B3?

A: The amount of lubricating oil in the RV Worm Gear Reducer depends on the installation orientation. If the installation method differs from B3, it must be specified when ordering so that the manufacturer can adjust the oil quantity or provide corresponding guidance.

Q4: How efficient is this gearbox?

A: Efficiency is an important indicator, depending on the design and friction conditions of the worm gear transmission pair. The product uses a hardened tooth surface transmission worm, which is highly efficient and maintains stable friction characteristics under both dynamic and static conditions.
