Gear reduction and increased torsion: The spur gear reduction you mentioned will result in an increase in torsion at the hub gear, which will be twice what the servo produces. This increased torsion is achieved by transferring the power from the servo into a gear train.
MOD 0.8 servo gears: The pinion gear train utilizes MOD 0.8 servo gears to achieve the desired reduction ratio. MOD 0.8 refers to the specific module size of the gear teeth, which determines their and compatibility. These servo gears are specifically designed for use with servos.
40 tooth servo gear and 80 tooth hub gear: The spur gear train includes a 40 tooth servo gear, which is commonly used to drive an 80 tooth hub gear. These gears are spaced 48mm apart to achieve a 2:1 gear ratio. This ratio represents the relationship between the number of teeth on the gears and determines the speed and torque output.
Good-quality brass material: The servo and hub gears you mentioned are made from good-quality brass material. Brass offers excellent ductility and resistance, allowing the gears to handle the stresses and strains of operation effectively. The use of brass contributes to the durability and reliability of the gears.
Stable structure and long service life: The spur gears in the gear train are designed with a stable structure, providing consistent performance. The use of high-quality brass material and precise manufacturing processes contribute to the gears' stability. This stability, combined with the longevity of the materials used, results in a long service life for the gears.
