Two gear parameters measured, how to determine whether they can mesh and drive type?
There are three types of transmission: Zero drive, straight drive and negative drive.It depends on the coefficient of displacement x,X=0 (invariant bit) and x1+x2=0 (high bit shift) are zero drivesX1+x2>0 (angular shift) is the right moveX1+x2<0 (angular displacement) is the negative drive
(actually, m1*cosa1=m2*cosa2 is the basic condition for meshing, so in special cases m and a can not be equal, as long as they conform to the upper case.)
Determine whether the gears can mesh as long as the modulus m and the pressure angle a are equal.Generally m and a are equal, you can mesh, or else you can not.
