How to choose gear tooth number of gear reducer with a speed ratio of 20?
Reduction ratio of 20 gear reducer, how to select the number of gear teeth. If the transmission power is not large, you can choose from the small gear, because the gear tooth strength is weak.According to the theory of least number of cutting teeth, the number of teeth of a small gear should not be less than 17 teeth. If the gear is selected, it should be at least 13 teeth. Modulus is calculated in terms of input power.In addition, according to the optimum transmission ratio theory, the single gear reduction ratio of the general spur gear should be between 3-4, so the single stage reduction ratio is 4. If the number of teeth in the pinion is 13 teeth, then the number of teeth of the large gear is 52 teeth.The speed reduction ratio is I 20, the deceleration ratio of each stage is 4, and the speed reduction of 5 is required.
In addition, according to the optimum transmission ratio theory, the single gear reduction ratio of the general spur gear should be between 3-4, so the single stage reduction ratio is 4. If the number of teeth in the pinion is 13 teeth, then the number of teeth of the large gear is 52 teeth.
