Features
FHTW PLF series is a economy type of planetary gearboxes.This type of speed reducers are belong to a kind of cost-optimized inline precision gearbox with shaft and square flange output. PLF series gear reducer offers an economic solution for most motion control or transmission system needs.PLF planetary reducer is also with high efficiency,low backlash,as an economy type inline gear reduction box,it is the most option for the limited budget requirement.
FHTW PLF planetary gear box has a wide range of ratio for different request,it divides into three reduction ratio stages:
Single stage:3,4,5,6,7,8,9,10
Double stage:12,15,16,20,25,28,30,35,40,50,70,80,100
Three stage:60,64,72,80,90,100,120,144,150,160,180,200,240,258,288,320,384,512,600,800,1000
PLF planetary gearboxes have a full input dimensions,match for any kind of servo motors and stepper motors.We accept dimension customized service according to motor dimensions.And if customer have a large quantity request,we supply OEM service with customer their own information.
PLF series planetary speed reducer is with square output flange design for economic transmission application.AS one of the most popular planetary speed reducers,PLF have the below features:
(1)Quiet operation
Helical gears contribute to reduce vibration and noise
(2)High precision
Standard backlash is 3 arc-min,ideal for precision control
(3)High rigidity &torque
High rigidity&high torque were achieved by uncaged needle roller bearings
(4)Adapter-bushing connection
Can be attached to any motor all over the world
(5)No grease leakage
Perfect solution using high viscosity anti-separation grease.
(6)Maintenance-free
No need to replace the grease for the life of unit.Can be attached in any position
Model Selection
PLF series precision planetary gearbox can connect to any brand of servo motors and stepper motors.
How to choose a correct PLF model?
(1)Check your motor drawing,offer the below dimensions:
φS:shaft diameter
LB:motor convex circle diameter
φLA:motor flange PCD
LS:shaft length
LE:motor convex circle thickness
φLZ:motor mounting hole size
Then compare these dimensions to our gearbox dimensions(refer to our catalogue)you can probably know the frame size of our gearbox.
(2)What’s the ratio or output speed you need?Check if the gearbox output torque＞motor torque*ratio
Ratio i=Input speed(RPM)/gearbox output speed(RPM)
Motor torque(N.m)=9550*motor power(KW)/motor speed(RPM)
(3)Make sure the precision(backlash)you need,then you can know which type of gearbox you need.
(4)If you don’t have the information above,please send us the servo motor dimension drawing for model selection or advise the specific servo motor model number,then we are pleasure to help you choose a suitable model.
