Module 1 Worm Gear Wheel & Shaft Set — Precision Drive Components for Robotics and Automation

When your motion-control project demands reliable torque transfer in a compact footprint, mismatched or low-tolerance gears become the weakest link. Engineers, robotics builders, and DIY automation enthusiasts who need a drop-in worm drive solution will find this Module 1 worm gear set delivers the dimensional accuracy and material integrity required for consistent, repeatable performance.

This listing covers a complete Module 1 worm drive pairing: a 30-tooth worm gear wheel available in brass, and a matching worm rod (shaft) in 45# medium-carbon steel. Gear wheel bore diameters range from 6 mm to 15 mm (approximately 0.24 in to 0.59 in), with optional keyway configurations (3×1.4 mm or 4×1.8 mm) for positive shaft locking. Worm rod outer diameters span 18 mm, 22 mm, 26 mm, and 28 mm (approximately 0.71 in to 1.10 in) depending on the selected bore variant.

Typical use cases include single-axis CNC router drives requiring a self-locking worm stage, compact conveyor indexing systems where a 30-tooth reduction ratio suits the cycle time, and small-batch robotic arm joints where a brass worm gear wheel pairs with a hardened steel worm rod for long service life.

⚙️ Compatibility: Module 1 standard. Worm gear wheel mates with Module 1 worm rods only. Verify bore diameter and keyway dimensions against your shaft before ordering.

✅ Key Features of These Module 1 Worm Gear Wheel & Shaft Components

🔩 30-Tooth Brass Worm Gear Wheel

Machined to Module 1 standard with 30 teeth, delivering a fixed gear ratio when paired with a single-start worm rod. Brass construction provides corrosion resistance and smooth meshing.

🔧 45# Medium-Carbon Steel Worm Rod

Worm shafts are turned from 45# steel for adequate surface hardness and toughness. Available in A-type and B-type configurations to suit different housing and bearing arrangements.

📐 Multiple Bore & Keyway Options

Gear wheel bores from 6 mm to 15 mm; worm rod bores from 6 mm to 15 mm with outer diameters of 18 mm, 22 mm, 26 mm, or 28 mm. Keyway slots (3×1.4 mm or 4×1.8 mm or 5×2.3 mm) available for positive torque coupling.

📦 Flexible Quantity Packs

Order as 1, 2, 3, 5, or 10 pieces per variant to match prototype or small-batch production needs without overstocking.

🔄 Self-Locking Drive Geometry

Module 1 single-start worm geometry provides inherent back-drive resistance, useful for positioning stages and lifting mechanisms that must hold position under load without a brake.

🏭 Broad Application Compatibility

Suitable for robotics joints, small CNC axes, conveyor indexers, camera pan-tilt rigs, and other compact mechanical drive systems requiring a right-angle speed reduction stage.

❓ Frequently Asked Questions

How do I choose the correct bore diameter for my shaft?

Measure your shaft diameter with a caliper. Select the bore option that matches your shaft size exactly — for example, a 10 mm shaft requires the 10 mm bore variant. If you need a positive torque lock, choose a keyway variant (e.g., 10 mm / 4×1.8 mm keyway) and machine a matching keyway slot into your shaft.

What is the difference between A-Type and B-Type worm rods?

A-Type and B-Type refer to the shaft end configuration and overall length profile of the worm rod. A-Type typically has a single plain shaft end, while B-Type may feature a different shoulder or end geometry suited to specific housing or bearing arrangements. Check the variant images and dimensions to confirm which type fits your housing design.

Can this worm gear set hold position under load without a brake?

Yes. A single-start Module 1 worm drive is inherently self-locking under most static load conditions, meaning the worm wheel cannot back-drive the worm rod. This makes it suitable for lifting stages, positioning arms, and indexing mechanisms that must hold position when the motor is de-energized. Confirm the lead angle and friction coefficient for your specific load before relying on self-locking in safety-critical applications.

What materials are used and how do they resist corrosion?

The worm gear wheel is machined from brass, which offers good corrosion resistance in typical indoor and light-industrial environments. The worm rod is made from 45# medium-carbon steel, which has moderate corrosion resistance. For humid or outdoor environments, consider applying a light machine oil or grease to the mating surfaces and exposed steel shaft areas.

Is this set compatible with other module sizes or gear types?

No. This worm gear wheel and worm rod are both Module 1 standard. They will only mesh correctly with other Module 1 worm components. Using mismatched module sizes will result in incorrect tooth engagement, accelerated wear, and potential failure. Always verify the module number of your existing drivetrain before ordering.

How do I select the right quantity pack for my project?

For prototyping or single-axis builds, the 1 PCS option is sufficient. For small-batch production runs or multi-axis machines, the 2, 3, or 5 PCS packs offer a per-unit cost reduction. The 10 PCS pack is suited for production batches or stocking spare parts. Select the Material & Amount variant that matches your required quantity and material combination.

What lubrication is recommended for this worm drive?

A medium-viscosity gear oil or lithium-based grease applied to the worm thread and gear wheel teeth is recommended. Worm drives generate sliding contact between the worm and wheel, so adequate lubrication is important for reducing heat buildup and extending service life. Re-lubricate periodically based on duty cycle and operating temperature.
