Low backlash right angle servo worm reducer
high precision worm equipment is an ideal substitute for precision planetary gearbox,the equipment manufacturer can substantially reduce the price of using precision planetary gearbox

The designer’s ideal solution is to rotate 90 degrees to install the servo motor drive systems

Worm shaft found in series can be driven by 1 motor to achieve synchronous outcome of multiple worm tires. It has been used in automated polishing cellular phone shell and other equipments
Servo worm gear units have three types : 45 – 50 – 55 – 63 – 75 – 90 ,with dual business lead worm drive.Left and ideal flank of worm shaft working with different lead angle,leading to tooth thickness gradual transformation,So that you can maneuver worm shaft and change backlash.

Low backlash Features :

— Worm equipment gyration backlash can be adjusted to less than 1 arc.
— Reducer could be re-adjusted the gap after using .
— Input with coupling : reliable without backlash .
— Output using conical clamping ring couplings : reliable without backlash.

Applications :

Precision rotary motion

— Reducing the noises and vibration that’s caused by the strain change and the modification of cutting force.
— reducing the noises and impact that’s due to the corotation and reverse.
— By lowering worm abrasion.
— Increasing worm output response acceleration .

Precision Indexing device

— CNC machine, assembly line, cutting machine, transmission lines, etc.
— Indexing device,accurate reading mechanism require accurate movements occasions .

Speed changing situations

— Reducing the noises and the impact that’s due to speed change.
— Reducing the worm abrasion that is caused by speed changes.

OUTPUT TORQUE
1、Rated output torque
Mn2 [Nm]
The torque that can be transmitted continually through the output shaft, with the apparatus unit operated under something factor fs = 1.
2、Required torque
Mr2 [Nm]
The torque demand based on application requirement. It is suggested to be equal to or less than torque Mn2 the gearbox under review is rated for.
3、Calculated torque
Mc2 [Nm]
Computational torque value to be used when choosing the gearbox. It is calculated considering the needed torque Mr2 and service factor fs, as per the partnership here after:
POWER
1、Rated input power
Pn1 [kW]
The parameter are available in the gearbox rating charts and represents the KW which can be safely transmitted to the gearbox, predicated on input speed n1 and service factor fs= 1.
2、Rated output power
Pn2 [kW]
This value may be the power transmitted at gearbox output. it might be calculated with the next formulas:
EFFICIENCY
Efficiency is a parameter which has a major influence on the sizing of certain applications, and basically depends upon gear pair designelements.
The mesh info table on page 9 shows dynamic efficiency (n1=1400)and static efficiency values.
Understand that these values are only achieved after the unit has been run found in and reaches the working temperature.
1、Dynamic efficiency
[ηd]
The dynamic efficiency is the relationship of power delivered at output shaft P2 to power applied at input shaft P1:

2、Static efficiency
[ηs]
Efficiency obtained at start-up of the gearbox. Although that is generally not significant element for helical gears, it might be instead critical when selecting worm gearmotors functioning under intermittent duty.
SERVICE FACTOR [ fs ]
The service factor (fs ) depends on the operating conditions the gearbox is subjected to the parameters that need to be taken into consideration to choose the most enough servies factor effectively comprise:
1. type of load of the managed equipment : A – B – C
2. length of daily functioning time: hours/day(△)
3. start-up frequency: starts/hour (*)
TYPE OF LOAD: A – uniform, fa≤0.3
B – average shocks, fa≤3
C – large shocks, fa≤10
fa=Je/Jm
–Je(kgm2) minute of the exterior inertia reduced at the drive shaft
–Jm(kgm2) point in time of inertia of motor
–If fa>10 please contact our Technical Service

series has a 90 degree source via helical bevel gear,and its giant tapered roller bearings also produce it ideal for high radial and axial forces. PAR right angle reducer features an extremely short, light however rigid housing and complete compatibility with standard electric motor adapters.PAR right angle planetary gearbox combines the advantages of a compact right angle gearbox and the ones of a typical planetary gearbox.Highest Accuracy, Highest Torque and Quiet Operation are provided by 100% optimized Helical Gearing.

With the compact structure but powerful design, PAR right angle planetary gearbox is ideal option for motion control applications wherein the power flow has to be redirected. So that it can support users to save the running cost and improve the transmission efficiency. The input flange dimensions of PAR proper angle gearbox is open to be customized, therefore, it is compatible with any makes of the servo brushless DC motors, motors and stepper motors.
