APPLICATION EXAMPLES

REPRESENTATION OF LOADS
The loads acting on the shafts can be: radial (radial force) and axial (axial force), referred to the axis of the shaft; when ordering specify whether the load is pull or push type. Fr - force / radial load acting in perpendicular direction to the shaft / axis Fa - force / axial load acting of the shaft / axis T = torque

PUSH	PULL

GEARBOX LIFETIME CALCULATION

Calculation applied to all models of the catalog

THEORETIC EXPECTED LIFE✽ = 10.000H X Fu

RECOMMENDED TORQUE (Nm)
Fu = --------------------------------------------
APPLIED TORQUE (Nm)

✽ The lifetime of 10.000h considers the following conditions:
• Applied torque = advised torque (see tables)
• Maximum of 8 working hours per day
• Working temperature 20 °
• No shocks

GLOSSARY

FR = radial force

FA = axial force

R = efficiency

T = torque

Tm = maximum torque

Tr = recommended torque

Ta = applied torque

To = output torque

Ti = input torque

Pn = power

N = Newton

Nm = Newton meter

fu = use coefficient

i = transmission ratio

rpm = revolutions per minute (1/min)

n1 = input shaft

n2 = output shaft

M = protruding / male shaft

F = blind hollow shaft / female

F = through hollow shaft / female

⦿ For correct sizing is necessary to know: transmitted power (Pn), output torque (T) and input rotation speed (rpm).

⦿ To identify the most suitable gearbox for your requirements, refer to the values in the table. If the real loads and efficiency are very close to the table values, contact the technical department.

⦿ All tables show linear measurements expressed in <mm>, unless otherwise specified. All the reduction ratios are expressed as a <fraction> unless otherwise specified. All forces, efficiency and the loads are expressed in <N or Nm> (10 N ≅ 1 kg or 10Nm ≅ 1Kgm ) unless otherwise specified.
