Built-in Freewheels FXRV and FXRT
for bolting to the encounter
with sprag raise-off X and torque restricting

Characteristics
Built-in Freewheels FXRV and FXRT are sprag freewheels with no bearing support and with sprag carry-off X&interval They consist of the Built-in Freewheels FXM with extra torque limiter&interval The sprag carry-off X assures a dress in-free freewheeling operation when the inner ring rotates at large pace&time period The freewheels FXRV and FXRT are employed as&colon
Backstops
for steady conveyor installations with numerous drives in which every single drive is geared up with
its possess backstop&time period In these kinds of constant conveyor installations with several drives it is important
to consider the dilemma of the unequal distribution of backdriving torque to the person
drives and backstops&period As before long as the set up arrives to a standstill&comma the complete backdriving torque is used largely to a one backstop&comma thanks to distinctions in the enjoy and elasticity of
the drives concerned&period of time In installations equipped with backstops with no torque limiters&comma the individual gearboxes and the corresponding backstops must be created to accommodate
the complete backdriving torque of the conveyor set up in purchase to ensure basic safety&period

The issue of the unequal distribution of backdriving torque is solved by employing backstops
FXRV and FXRT with torque restricting&period of time The torque limiter which is constructed into the backstop slips
briefly when the specified torque is exceeded right up until the other backstops interact in succession&time period In this way&comma the total backdriving torque of the conveyor set up is dispersed
to the individual gearboxes and backstops&interval Moreover&comma dynamic peak torques which happen during the loc ept method are reduced&comma thus safeguarding the gearboxes from harming
peak torques&interval For this reason the use of backstops FXRV and FXRT with torque restricting
in ongoing conveyor installations with multiple drives permits the software of gearboxes
with smaller dimensions&period of time

Positive aspects
1&period Protection of gearboxes from overload by unequal load distribution in numerous drives
two&periodProtection of gearboxes from dynamic peak torques for the duration of the loc ept method
three&time period More compact gearboxes can be utilized with out negatively effecting the basic safety
four&periodProtection of the backstops&comma as dynamic peak torques are reduced by temporarly slipping
