When designing gear meshing, pay attention to the width of the small gear 5-10 mm wider than the large gear.Such benefits:

1. If the width of the two gears is the same, the installation error will cause the centers of the two gears to fail to coincide when they are matched, that is, some "axial misalignment" will inevitably occur, and the ends of the large gear and the small gear will be misaligned by a small distance , Thereby reducing the actual meshing width of the gear, resulting in lower connection strength and fatigue strength;

2. In order to mesh all the tooth widths, the small gear can be made wider than the large gear, so even if there is some error, it can mesh all the tooth widths to ensure the actual meshing tooth width;

3. The pinion gear has high speed and wide width, which can improve the strength and service life;

4. As for why it is to widen the small gear instead of widening the gear: because widening the large gear will be more expensive than widening the small gear; widening the small gear is the best choice for saving materials and reducing weight.
