Standard Flat Involute Helical Gear Pair

GB/T6446 Standard Planar Spiral Bevel Gearbox with Flat Second Involute Envelope, externally unchanged but internally modified with worm gears. The Planar Second Involute Spiral Bevel Gear Set, known for its high load-bearing capacity and transmission efficiency, is particularly suitable for heavy-duty, high-power equipment and has been widely used in industries such as metallurgy and mining.

The helical gear parameters are optimized by computer selection. The helical gears, reducers, and worm gears are designed with computer-aided design. The face hobbing machine tools and process routes ensure consistent machining of the worm and worm gear cutters according to their principle, without the need for reshaping.
