PC Series Pre-stage Helical Gear Reducer

     Shanghai guzuo PC series pre-stage helical gear reducer is a compact front-mounted helical gear unit

designed for combination drive. Adopting high-precision hardened helical gears and die-cast

aluminum alloy housing, this pre-reducer is usually installed in front of worm gear reducers to expand reduction ratio and increase output torque. Featuring small size, high efficiency

and easy assembly, it is the best matching module for NMRV, VF and other worm gearboxes to realize

multi-stage deceleration.

Main Features

• Modular Combination Design: Professional pre-stage reduction unit, perfectly matched with worm gear reducer to achieve large reduction ratio.

• High Hardness Helical Gears: Alloy steel quenched helical gears ensure high hardness, wear resistance and strong torque capacity.

• Lightweight Aluminum Housing: Die-cast aluminum alloy shell provides excellent heat dissipation performance and anti-corrosion ability.

• Smooth & Low Noise: Optimized gear meshing structure ensures stable transmission and low running noise.

• Easy Installation & Maintenance: Standard PAM flange connection, simple assembly without complicated modification.

• Cost-effective Upgrade: Effectively improve torque and expand speed ratio without changing the main reducer structure.

Application Scope

Precautions

• PC reducer cannot be used independently, it must be combined with the main reduction gearbox.

• Avoid long-term overload operation to prevent helical gear wear and tooth breakage.

• Keep clean lubricating oil to ensure smooth combination transmission.
