Helical gear reducers

As enclosed mechanical power transmission devices, Feida helical gear reducers use two or more sets of helical gears meshing to lower speeds and increase torque,which feature smoother operation,lower noise,higher-load capacity ,high transmission efficiency,and compact design.

Main Structure

Helical gears: They are the core components responsible for power transmission and speed reduction.

Bearings: Support the rotating shafts, reduce friction and wear, and withstand the radial and axial forces generated during gear meshing.

Housing: the primary supporting component of the reducer. It supports the gear and shaft assemblies, contains the lubricant, protects the internal components, and is commonly made of cast iron, cast steel, or high-strength aluminum alloys.Seals:Prevent pil leakage and contamination.

Input and Output Shafts: The input shaft receives mechanical power from the motor or another power source, while the output shaft transfers the reduced-speed power to the driven machinery.

Working Principle

The basic working principle of helical gear reducers is to utilize the difference in the number of teeth between gear pairs to achieve a reduction in rotational speed and an increase in torque.

Manufacturing Process & Quality Control

Feida Machinery produces helical gear reducers in a 45,000 m² facility under ISO 9001:2015 quality management. Annual production capacity is approximately 15,000 tons.

Production steps for key components

Quality Control

Each batch of products is inspected at every stage from raw materials to final products, including incoming quality control (IQC), in-process quality control (IPQC), final quality control (FQC), and outgoing quality control (OQC).

Application

Conveyor Systems

Used in belt conveyors, chain conveyors, roller conveyors, and other material-handling systems. They provide stable low-speed, high-torque power for conveying operations.

Industrial Mixing Equipment

In mixers and blending machines, reducers lower the motor speed and increase output torque, enabling the mixing shaft to operate at an appropriate speed.

Lifting and Material-Handling Equipment

Used to drive hoist/winch drums, travel mechanisms, and other operating components in cranes, hoists, and other material-handling systems where reliable power transmission is required.

Mining and Construction-Material Machinery

Designed to accommodate accommodate relatively high loads and continuous operating requirements in crushers, screening machines, feeders, and other mining equipment.

How to maintain and care for gear reducers?

Proper maintenance can reduce failure rates and extend the service life of helical gear reducers.The key maintenance and care points include:

.Check the Lubricating Oil Regularly

.Monitor Operating Temperature

.Check for Abnormal Noise and Vibration

.Inspect Seals and Fasteners

.Avoid Overloading

FAQ

How to guarantee gear quality?

Each gear has been hobbed,heat treated ,and cnc ground.Its precision grade can be up to ISO/DIN 5-10 level.

How to guarantee housing quality?

Each housing has been processed by CNC machining center to ensure the precision of each side.For the material,we insist on HT250 steel.

What are common materials?

A variety of materials are available,including carbon steel,alloy steel,gray cast iron, ductile iron, cast steel, aluminum alloy,bearing steel,nitrile rubber, fluorocarbon rubber, polyurethane,and stainless steel.

How does gear ratios affect speed and torque in gear reducers?

Gear ratios determine how input speed is reduced and torque is increased. A higher gear ratio cuts output speed but multiplies torque, directly impacting mechanical performance.

What are common types?

The common types include single-stage,two-stage,three-stage and multi-stage helical gear reducers
