Gear reducers & Screw jacks - General information





Used in automation and robotics, these products can also be used with motors to create lifting and positioning systems. Multiple sectors of application: packaging machines, machines for wood/metal/stone/glass/plastic/paper; food, chemical, and pharmaceutical industries; warehouses, transfer systems, conveyor systems, production processes, etc

RD reducers
Used to reduce speed and increase torque; adaptable to many applications and products with varying weights, dimensions, product types, etc.
• Cost efficient, energy efficient, silent, with low maintenance requirements.
• Three sizes:  RD26 - RD40 - RD50. 
• Housing made of anodized aluminum, shafts and gears made of hardened steel with surface treatment highly resistant to wear
• Various reduction ratios
• Available with male and female shafts; please refer to the technical specifications for dimensions
• Manual or motorized movement; adapters are available for connection to the sides of the machine, motors, and displays
• Special versions with flanges and longer input shaft are available to install OP2, OP3, OP7, or EP7 indicators
• Available with magnetic sensor, motor, or geared motor

MAR lifting jacks
Used to lift, pull, move, align, and position
• Two sizes: MAR40 and MAR50
• Various reduction ratios
• Housing made of anodized aluminum, shafts and gears made of hardened steel with surface treatment highly resistant to wear
• Lead screw made of AISI 304 stainless steel
• Manual or motorized movement; adapters are available for connection to shafts, gearboxes, motors, and displays
• Special versions with flanges and longer input shaft are available to install OP2, OP3, OP7, or EP7 indicators
• Applicable separately or connected in groups
• FIAMA can supply complete systems

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.
