If velocity ratio is less than 3, then centre distance is given by D+.5d.
A shorter centre distance is always preferred in belt drives.
It is possible to use the belting reverse direction without violating the law of belting.
The law of belting states that the centreline of the belt when it approaches a pulley must not lie in the midplane of the pulley.
Vertical drives are preferred over horizontal.
The optimum velocity of the belt for maximum transmission is given by √P/6m.
