The teeth of spiral bevel gears are distributed in a spiral curve along the pitch cone, which is in sharp contrast to the straight tooth structure of spur bevel gears. This unique tooth line design makes the tooth surface contact area wider during the gear meshing process, and the contact stress can be effectively dispersed.
spiral bevel gear Detail
| Product Name | spiral bevel gear |
| Product Material | The core of the spiral bevel gear is made of brass, which has a high copper content. At the same time, elements such as zinc are added, and the zinc content can be flexibly adjusted according to actual needs. |
| Product Process | In the rough machining stage, milling, gear hobbing and other methods are used to complete the gear blank forming, tooth surface rough machining and preliminary tooth groove structure in sequence, accurately shaping the initial shape of the gear. |
| Surface Treatment | Tin plating, galvanizing, passivation, blackening, electrophoretic coating and other methods can be selected to meet different protection and appearance requirements |
| Customizable Products | Gears / Sprockets / Worms / Shafts / Rack Bars / Bevel Gears, etc. |

1. What are the materials of spiral bevel gears? What are the advantages and disadvantages of different materials?
Common materials include 20CrMnTi, 42CrMo alloy steel and carburized steel. 20CrMnTi has high surface hardness and good wear resistance after carburizing and quenching, and the cost is moderate; 42CrMo has excellent comprehensive mechanical properties and is suitable for heavy-duty conditions but the price is relatively high.
2. What is the heat treatment process of the product?
Carburizing and tempering processes are usually used. Carburizing can make the surface hardness of the gear reach HRC58-62, the core maintains toughness, and improves wear resistance and fatigue resistance. Some high-precision gears will also be nitrided after grinding to further improve the surface hardness and anti-bite ability.
3. Can your company's spiral bevel gears be customized?
Customization is supported, and can be designed according to parameters such as modulus, pressure angle, helix angle, and tooth surface shape. The customization process is demand communication → drawing confirmation → sample trial production → mass production.
