Definition and Calculation of Gear Ratios

The gear ratio in starter motor design standards refers to the relationship between the rotational speeds of the driving gear (pinion) and the driven gear (ring gear). It determines how many turns the motor shaft must make to rotate the gear and engage the engine.

Calculating the gear ratio involves dividing the number of teeth on the driven gear by the number of teeth on the driving gear:

• Gear Ratio = Number of Teeth on Driven Gear / Number of Teeth on Driving Gear.

For example, if the ring gear has 60 teeth and the pinion has 10 teeth, the gear ratio is 6:1. This indicates that the motor’s output shaft turns six times for each revolution of the pinion.

Understanding this ratio helps optimize starter motor performance by balancing torque and speed, which is essential in adhering to established gear reduction standards. Proper calculation ensures efficient engagement while maintaining compliance with industry norms.
