FHTW high torque planetary gearbox speed reducer gear box for stepper motor transmission reduction gearbox

FHTWplanetary gearboxes with output flange are characterized by a compact flange interfacethat work together to provide excellent motor drive transmission operation.The geometry on the output side of the flange gearbox is based on the most common industrial robot.

The flange output gearboxes offer the advantage that other drive components such as flanged pinions or couplings, can be connected quickly and easily without requiring major adjustments.The mechanical connection of this flange gearbox to usermachine is executed quickly and simply.Besides,it is also secured by a dowel hole in the output flange.

The function and structure of FHTWflange gearboxes are comparable to the planetary gearboxes with output shaft, but in a much more compact form. This is because they have very short flanged shaft geometry, unlike a cylindrical output shaft.

This flange output speed reducer is withlarge diameter, which allows for a higher achievable torsional stiffnessand torque.These planetary gearboxes are particularly suitable in applications with changing directions of motion. In conjunction with a pulley, you can use our flangeoutputgearboxes with many different types of belt for the drive system.

Thanks to the versatility of our planetary servo gearboxes, we can offer you a range of solutionsaccordingto your differentrequirements.If the motion load and output torque is small,you can choose DG series to save the budget.If for the large load transmission system that needs higher torque and low noise,the PAD planetary gearbox is the ideal option.

Our versatility gives you the opportunity to adapt the gearbox characteristics to suit your requirements, depending on the area of use.

For transmission systemswith medium backlash requirements, we also have a solution in the shape of the ZK, which comes in multiple frame sizes and ratios.

The input flange of the planetary gearbox is individually adapted to the motor. The compact unit and servomotor increases your flexibility.The available customized dimensions of input side makes FHTW planetary gearboxes suitable for any kinds of stepper motors and servo motors.You can send servo motor dimension drawings for model selection or advise the specific servo motor model number.

PAD series is a hollow shaft planetary gearbox.It can be fast connectedto any motor output shaft.The rotating output flange replaces the traditional output shaft, giving it a unique power transfer solution.

The PAD planetary gear on the shaft is supported by both ends of the full needle roller bearing, which enhances the torsion stiffness.The output shaft of PAD planetary gearbox is supported by two taper roller bearings for greater carrying capacity

The PAD hollow shaft planetary gearbox is with highest torsional stiffness, tilting moment and compactness.Backlash of PAD planetary gearbox can be to 1 arcmin.With the excellent positioning performance and high torque,PAD planetary gearbox is specially suitable for the motion occasion of high positioning precision, dynamic cyclic operations and compact solutions for motion control, automation, CNC machines and robotic.PAD planetary reducers have been used by famous manufacturing companies, such as Samsung, Canon and LG,etc.

Input size of PAD planetary gearbox iscustomized,it can replace of similar models from other factories.So it is suitable for all kinds of servo motor and stepper motor.PAD inline planetary gearbox have various of speed reduction from 4-100.

PAD series planetary speed reducers features

PADseries planetary gearbox is with round output flange and output hollow shaft.

PAD gearbox has the features of:

(1)High precision

Standard backlash is 3 arc-min,ideal for precision control

(2)High rigidity&torque

High rigidity & torque were achieved by uncaged needle roller bearings.

(3)High load capacity

Adopting taper roller bearing for the main output shaft to increase radial and axial load.

(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.


No need to replace the grease for the life of the unit.Can be attached in any position.

Model option guidelines

How to choose a correct PAD 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.

After determine the above, you can choose a smallest volume gearbox to save cost.

If you have special requirement for the precision, please clarify.
