- How to choose the pair rack and pinion
As long as the modulus ( pitch ) the same , spur gears, internal gears, rack can fit.
For example, 0.8 analog gear rack module with 0.8 ; 1.0 1.0 module with analog gear rack ; 2.0 2.0 module with analog gear rack ; and so on ...... - About modulus
Modulus ( meaning that pitch ) ; detailed resolve See link :
bangpai.taobao.com/group/thread/160598-282528895.htm - About reduction ratio
Such as the ratio of 1: 1 , optional 20 tooth gear ratio 20 , 34 34 tooth gear ratio and so on ;
Such as the ratio of 1: 2 , optional 20 tooth gear ratio 40 ; 30 60 tooth gear ratio ; 50 100 tooth gear ratios etc ;
Such as the ratio of 1: 6 , 60 tooth gear ratio Optional 10 ; 12 72 tooth gear ratio ; 20 120 tooth gear ratios etc ;
And so on ...... - About gear center distance
Formula: center distance = ( big + pinion gear teeth ) * modulus / 2 ;
As is known, two -axis center distance is 30mm, 1.0 modulus selected gear ;
To choose the ratio of 1 : 1 gear , the formula 30 = ( 30 + 30 tooth gear ) * 1.0 / 2, that the election two gears to a mold 30 ;
To choose the ratio of 1: Gear 2 , the formula 30 = ( 20 + 40 tooth gear ) * 1.0 / 2 , namely the election 20 teeth and 40 teeth each one can be;
And so on ...... |
