What is a two stage gear? How do I achieve the 1:10 drive ratio? How many gears do you need? What is the diameter ratio?
The two gear is two gear reducer, the input speed can be reduced, and the input torque, driving you say more than 10 may be able to find a standard speed reducer, if can't find words for their own design. There is a formula of the transmission ratio of the distribution of I, 1.3~1.4 times i1= rootTake an intermediate value of 1.35, 1.35i=1.35*10=13.5After prescribing i1=3.67, i2=i/i1=10/3.67=2.72.
Complete, it should be called two-stage gear reducer. It is a two stage drive, and the total drive ratio is multiplied at all levels.Two stage drive requires 4 gears. As for the diameter ratio (the dividing circle, not the outer diameter), that is the reciprocal of the transmission ratio.In theory, single stage transmission ratio of the square root of 10, the size of the minimum. In order to make it convenient, it is better to choose 3*3.333.
A building is two levels of mean transmission ratio are the same, it is not suitable for the other, because the gear reducer torque will increase, in general will be a larger value in the selection of transmission ratio distribution of transmission ratio, while the two stage transmission ratio to be smaller, smaller than three transmission gear, so on and the shaft bearing capacity allocation will be reasonable.I suggest you according to the above two people drive ratio, rely on the standard transmission ratio, and then select the standard transmission ratio, re correction, and then proceed to the next design. But the design behind that will be a bit troublesome, not one day, two people will be able to calculate. I have a model here. You can do it, but the score you give is too small to be given to you casually.
