Low backlash right position servo worm reducer
high precision worm gear is an ideal replacement for precision planetary gearbox,the gear manufacturer may substantially reduce the expense of using precision planetary gearbox

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

Worm shaft in series can be driven by 1 motor to achieve synchronous output of multiple worm wheels. It’s been used in automatic polishing mobile phone shell and other equipments
Servo worm gear models have three types : 45 – 50 – 55 – 63 – 75 – 90 ,with dual lead worm drive.Left and ideal flank of worm shaft working with different lead angle,causing tooth thickness gradual transformation,To be able to move 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 working with conical clamping ring couplings : reliable without backlash.

Applications :

Precision rotary motion

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

Precision Indexing device

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

Speed changing situations

— Reducing the sound and the impact that is due to speed change.
— Cutting down the worm abrasion that is caused by speed changes.
Low rotation Make decision :

The next headings contain information on essential factors for selection and correct make use of gearbox.
For specific data on the gearbox array,start to see the relevant chapters.
OUTPUT TORQUE
1、Rated output torque
Mn2 [Nm]
The torque which can be transmitted consistently through the output shaft, with the gear unit operated under a service factor fs = 1.
2、Required torque
Mr2 [Nm]
The torque demand predicated on application requirement. It is suggested to be add up to or significantly less than torque Mn2 the gearbox under study is rated for.
3、Calculated torque
Mc2 [Nm]
Computational torque value to be used when choosing the gearbox. It really is calculated considering the expected torque Mr2 and service issue 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 that can be safely transmitted to the gearbox, based 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 can be calculated with the following formulas:
EFFICIENCY
Efficiency is a parameter that includes a major effect on the sizing of certain applications, and basically is determined by gear pair designelements.
The mesh info table on page 9 shows dynamic efficiency (n1=1400)and static efficiency values.
Remember that these values are only achieved after the unit features 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 in start-up of the gearbox. Although that is generally certainly not significant point for helical gears, it could be instead critical when choosing worm gearmotors operating under intermittent duty.
SERVICE FACTOR [ fs ]
The service factor (fs ) depends upon the operating conditions the gearbox is put through the parameters that require to be taken into consideration to choose the most adequate servies factor appropriately comprise:
1. type of load of the managed machine : A – B – C
2. length of daily working time: hours/day(△)
3. start-up regularity: starts/hour (*)
TYPE OF LOAD: A good – uniform, fa≤0.3
B – moderate shocks, fa≤3
C – serious shocks, fa≤10
fa=Je/Jm
–Je(kgm2) moment of the exterior inertia reduced at the drive shaft
–Jm(kgm2) moment of inertia of motor
–If fa>10 please contact our Technical Service

B -Winding devices, woodworking machine feeders, products lifts, balancers,threading equipment, method mixers, conveyor belts for heavy materials,winches, sliding doors, fertilizer scrapers, packing equipment, cement mixers, crane mechanisms, milling cutters, folding machines, gear pumps.
C -Mixers for heavy supplies, shears, presses, centrifuges, rotating supports, winches and lifts for major materials, grinding lathes, natural stone mills, bucket elevators, drilling equipment, hammer mills, cam presses, folding equipment, turntables, tumbling barrels, vibrators, shredders.
series includes a 90 degree suggestions via helical bevel equipment,and its giant tapered roller bearings also make it ideal for great radial and axial forces. PAR right position reducer features an exceptionally short, light but rigid housing and total compatibility with standard electric motor adapters.PAR right angle planetary gearbox combines the features of a compact right angle gearbox and those of a typical planetary gearbox.Highest Accuracy, Highest Torque and Quiet Operation are given by 100% optimized Helical Gearing.

With the compact structure but powerful design, PAR right angle planetary gearbox is ideal option for action control applications wherein the energy flow needs to be redirected. So that it can support users to save lots of the running price and improve the transmission effectiveness. The input flange sizes of PAR right angle gearbox is available to be customized, therefore, it is appropriate for any makes of the servo motors, stepper motors and brushless DC motors.
