Worm and worm-wheel sets for high-ratio right-angle transmission and compact speed reduction. This page is prepared for model identification, preliminary selection and quotation. The exact production configuration should be confirmed before order placement.
M2.5 1:40 Worm Gear Set (model WORM-M2.5-R40) is a standard item in the KEDI Worm Gears range, with Module 2.5; Ratio 1:40; Worm Starts 1; Wheel Teeth 40. It is produced to drawing and standard, inspected for dimensions and hardness before shipment, and can be supplied alone or as a matched set with mating transmission parts. Material, heat treatment, bore and surface finish can be adapted to the application.
| Material | C45 / S45C carbon steel, 42CrMo alloy steel, stainless steel; cast iron or aluminium for pulleys; nylon for light-duty racks |
| Heat treatment | Quenching and tempering, induction hardening of teeth, carburising for high-load gears |
| Tooth finish | Hobbed or milled standard; shaved or ground for higher accuracy grades |
| Surface | Black oxide, zinc plating, phosphating or natural finish with anti-rust oil |
| Custom options | Bore and keyway, set-screw holes, hub length, helix hand, mounting holes and lengths to drawing |
Yes. Send a 2D/3D drawing or a sample; module, tooth count, bore and material can all be customised.
Yes. The pinion must have the same module and helix angle with the opposite hand; we supply both as a matched set.
Racks are machined with matched end pitch so segments can be joined continuously using a joining gauge.
