Brass Worm Wheel

A brass worm wheel is the wheel part of a worm gear drive, meshing with a worm shaft to transmit motion and torque at a 90° shaft angle. Brass and bronze alloys are used because they offer low friction, good wear resistance and self-lubricating properties when paired with a hardened steel worm.

Raydafon standard production uses ZCuSn10Pb1 tin bronze with hardness HB≥80 and wear resistance about 30% higher than ordinary brass. Other bronze or brass grades can be used on request depending on load, speed and environment.

The gear is processed through five precision steps — casting, rough turning, fine turning, hobbing and grinding — reaching tooth surface roughness Ra≤1.6μm and meshing error below 0.05 mm with the matching worm. Transmission efficiency is about 15% higher than the national standard, and a 5000-hour continuous operation test shows wear rate below 0.01 mm per 100 hours.

Standard sample: module 0.5, 20 teeth, teeth diameter 11.2 mm, height 12 mm, outer diameter 11 mm, bore 4 mm, weight 16 g. Matching worm gear shaft: height 20 mm, outer diameter 9.8 mm, inner diameter 3.17 mm. Custom module, teeth number, outer diameter 50-300 mm and bore are supported.

Applications include excavator slewing mechanisms, forklift lifting systems, rolling mill roller transmission, steel spout tilting devices, CT scanner rotating frames, dental chair adjustment, deck crane luffing, ship steering systems, automated warehouse stackers and sorting line steering devices.

Send drawing or sample details, module, teeth number, outer diameter, bore, material grade, quantity and destination port. Raydafon will reply with an FOB Ningbo quotation and lead time.

Standard orders ship in about 15 days after order confirmation. Custom or bulk orders depend on drawing complexity and quantity. Raydafon provides an updated schedule after drawing approval.
