Custom Precision Worm Shaft and Worm Gear for Low-Noise Power Transmission

Product Description

Laiwei manufactures custom worm shafts and worm gears for precision mechanical transmission systems, providing compact speed reduction, stable motion transfer and high torque output for industrial equipment, automation systems and customized gearboxes.

This worm shaft and worm gear set features a cylindrical transmission structure and is manufactured with controlled gear geometry to support smooth tooth engagement and consistent operation. With a specified backlash of ≤0.05 mm, hardness of HRC 45–60 and gear tolerance grades from ISO 6 to ISO 8, the components are suitable for applications where positioning accuracy, controlled motion and reliable transmission are important.

Rather than supplying only standard off-the-shelf gears, Laiwei focuses on drawing-based and sample-based custom manufacturing. Worm diameter, gear dimensions, shaft structure, module, number of starts, reduction ratio, material, hardness, surface treatment and other specifications can be produced according to the requirements of your transmission system.

Our in-house capabilities cover CNC turning, Swiss-type CNC machining, turning and milling, gear hobbing, worm machining and precision inspection, allowing us to support projects from prototype development through repeat production.

Typical Product Specifications

Actual specifications are determined by customer drawings, samples and application requirements.

Key Features & Benefits

1. Low Backlash for Controlled Motion

With backlash controlled to ≤0.05 mm, the worm and gear set can provide more predictable rotational transmission and help reduce unwanted movement between mating components.

This makes it suitable for mechanisms where repeatability, positioning and controlled movement are more important than simple power transmission.

2. Smooth and Low-Noise Gear Engagement

The quality of worm gear transmission depends heavily on tooth geometry, concentricity, surface condition and correct matching between the worm and mating gear.

Laiwei controls the machining and inspection process to achieve stable gear engagement, helping reduce unnecessary vibration and operating noise in properly designed and lubricated transmission systems.

3. High Torque in a Compact Transmission Structure

Worm drive systems are widely used where a relatively large speed reduction is required within limited installation space.

The perpendicular shaft arrangement provides designers with a practical solution for transmitting motion between non-parallel shafts while increasing output torque through speed reduction.

4. HRC 45–60 Hardness for Wear Resistance

Depending on material and application requirements, the component hardness can reach HRC 45–60, providing the contact surfaces with improved resistance to wear under repeated transmission cycles.

Heat treatment requirements can be specified according to the customer's drawing and working conditions.

5. ISO 6–ISO 8 Gear Accuracy Options

Different applications require different levels of gear accuracy.

Laiwei supports worm and gear components manufactured to ISO 6 through ISO 8 accuracy requirements, allowing customers to select an appropriate balance between precision, performance and manufacturing cost.

6. Fully Customizable Gear Parameters

We manufacture according to your actual mechanical design instead of limiting customers to fixed catalogue dimensions.
