Involute Gears

Our gearbox use Involute Spur Gears, its better than straight sided axial worm.

Advantages of Involute Gears

Durable electric motor reduction gearbox, electric motor reduction gearbox, worm gearbox

1. The contact between two mating involute gear tooth moves along a fixed plane of contact irrespective of the centre to centre distance of the gears. Thus involute gears can handle centre shifts or you will get greater assembly flexibility.

2. Contact surface of gearbox is always perpendicular to the plane of contact, this helps reducing torque variation and thus involute gear gives silent operation.

3. Manufacturing fairly accurate gears of this type are quite easier by hobbing process.
