Custom Gear Ratios

Possible Gear Ratios (Non-Flipped)

The table below lists all possible gear ratios and associated free speeds for the non-flipped configurations of the Swerve X.

The first row shows the possible gear sets for the first stage. The first column shows the possible gear sets for the second stage. All free speeds are in ft/s.

Recommended Ratios

For the 2nd stage of the drive ratio, a 26T or smaller driven gear provides the required clearance for the module as it rotates. Listed in the table below are some recommended gear sets.

Driving Gear Tooth Count	Driven Gear Tooth Count
20	26
22	24
24	22

Possible Issues

When creating custom overall drive ratios, the gear set for the 2nd stage must be carefully selected. The driven gear for this stage cannot exceed a 26T tooth count, otherwise the gear will collide with the module spacers and sensor shaft as the wheel module rotates.
