About Idler Gear

Core Features of Idler Gear

Idler gear is an intermediate gear that does not directly drive the load, and it has the following characteristics.

Change the direction of rotation

When the two gears are directly engaged, their rotation directions are opposite, and in order to make the rotation direction of the driving and driven wheels the same, an IDLER gear can be added in the middle.

Adjust gear engagement clearance

Idler Gear can be used to eliminate backlash caused by manufacturing tolerances or wear. This can effectively reduce shock, vibration, and noise during transmission, especially suitable for high-precision scenarios such as robot arms and precision instruments.

Load sharing

In complex gearboxes, if Idler Gear is introduced, torque and load can be distributed over more teeth. This helps to reduce wear and tear on individual gears, extending the lifespan of the entire drivetrain.

Idler Gear Production Process

In order for our final customized gear products to be delivered to our customers to strictly meet the customer's requirements, we strictly follow the following process when producing idler gear.

Design and Analysis

If the customer has specific drawings, we directly analyze and simulate the test according to the customer's drawings. If the customer only provides the actual working conditions and requirements, our engineers will perform CAD gear geometry modeling and CAE tooth profile optimization according to the customer's needs.

Material Selection

According to the customer's specific application scenario (load, weight, corrosion resistance requirements), the most suitable material is selected, generally selected materials such as alloy steel, aluminum alloy or engineering polymer.

Precision Machining

High-precision CNC (Computer Numerical Control) lathes, milling machines, and gear hobbing machines/gear shaping machines (such as Kashifuji gear skiving machine, Ningjiang CNC gear hobbing machine, etc.) are used for processing to ensure that the outer circle, inner hole and tooth shape of the gear meet the size and shape required by the drawing.

Heat Treatment

For metal materials such as alloy steel, we will carry out precise heat treatment processes such as carburizing quenching and nitriding to improve their surface hardness and wear resistance.

Finishing and Surface Treatment

After heat treatment, IDLER GEAR workpieces can develop minor deformations and require fine grinding (e.g. boreholes, end faces) to restore the highest precision. At the same time, surface treatments such as nickel plating, blackening, and phosphating are carried out according to the needs to enhance corrosion resistance.

Quality Inspection

We use high-precision coordinate measuring machines, gear inspection machines, and roughness meters to conduct 100% or strict sampling inspection of gear diameters, modulus, tooth shape errors, accuracy levels (up to ISO level 5), etc., to ensure that all parameters meet specifications.

Cleaning, Packing and Delivery

After thorough cleaning and anti-rust treatment, qualified gears will be individually packaged according to your needs to prevent bump damage during transportation, and finally delivered to you by express, air or ship.
