VISCOSITY CALCULATION- Worm Gear Date:

Application Point:

Only yellow cells have

Inlet data :

Worm speed (n)1400

Wheel diameter (2 x d )65

Worm diameter ( d1 )39

Motor installed power ( P )

or

Motor installed power ( P ) 2.2

Lubricant required viscosity

Output :

Angular Speed = w (formula : (3,14 * n )/ 30 )

Installed power in = P (Hp x 75 ) or ( KW x 1032)

Charge = C ( formula : P / w )

Wheel radius in m = d ( formula : ((2.D)/ 2)) / 1000 )

Torque = M ( formula : C / d )

Center shafts distance = a ( formula : ((d1/1000/2)+(d))/2)

Cubic elevation of a = a3 ( formula :a*a*a)

KS/v factor ( formula : M / ( a3 * n))
