CONFIGURATION          

                                                   

                               


Naming is based on the configuration starting from the shaft pointing downwards n1 in the immage and proceeding clockwise.


     RADIAL AND AXIAL LOAD 
      Fr = 75 N, radial load, is the load acting in perpendicular direction to the shaft/axise   



Fa = 7 N, axial load, is the load acting of the shaft/axis  

T = 2 Nm output torque

The loads acting on the shafts can be of two types (referred to the axis of the shaft)
Fr - radial load 
Fa - axial load, when ordering specify whether the axial load is 'pull' or 'push' type. 
«The loads are generated by the items connected to the gearbox and can be created for example by the pull of belt drives, accelerations and decelerations, structural misalignments, vibrations, shocks, etc.» 
                      

 GEARBOX LIFETIME CALCULATION
Straight bevel gears
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 

➜ In case of continuous use, please contact our Technical Dept. In such applications, a grease fitting will be installed to allow periodic addition of lubricant with a frequency based on the work conditions.
