A helical pinion is a cylindrical gear with teeth that are cut in a helical (spiral) shape around the axis, rather than being straight (spur gears). This helical design offers advantages like smoother and quieter operation, and increased torque-carrying capacity compared to spur gears.
helical pinion gear Detail
| Product Name | Helical pinion gear |
| Product Material | Made of 45 steel, 40CR, 20CR/20CrMnTi, SUS304, suitable for various working conditions. |
| Product Process | Precision machining: The reference hole and outer circle are machined by annealing, turning and boring, followed by rough hobbing and fine hobbing to initially form the tooth profile, and then shaving is performed to correct it. The surface hardness and core toughness are improved through carburizing, quenching and tempering, and the tooth surface is finished by honing and grinding. |
| Surface Treatment | Options include hardening, nitriding, phosphating, coating, laser treatment and electroplating. |
| Customizable Products | Gears / Sprockets / Worms / Shafts / Rack Bars / Bevel Gears, etc. |
Product Advantages
High wear resistance
After carburizing, quenching, nitriding and other treatments, the surface hardness is enhanced.
Enhanced corrosion resistance
Through surface treatment process, a protective film is formed to prevent corrosion.
Stable transmission performance
The tooth surface roughness can be reduced through mechanical treatment such as honing and grinding.
Improve fatigue resistance
Shot peening forms a compressive stress layer on the gear surface to reduce the occurrence of cracks.
Product Information Parameters

What is a helical pinion gear?
Helical Pinions gear mate with helical gears which are cylinders with external involute radial teeth that spiral around the circumference. Helical pinions offer a refinement on the typical spur gear. Helical pinions can be made from customer-supplied materials, as well as materials provided by Stahl Gear & Machine Co.
What is helical pinion gear used for?
Helical pionion gears provide a means of connecting non-parallel shafts as well as provide an alternate means of connecting parallel shafts, serving the same purpose as spur gears. Cutters that produce an angle that allows several teeth to mesh simultaneously form helical gears.
What is the function of the helical pinion gear?
A helical pinion gear pair is on the driving shaft, the pair acts to reduce speed and to amplify torque; if the pinion is on the driven shaft the pair acts as a speed increaser and a torque reducer.
