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

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

Worm shaft found in series can be driven by one motor to achieve synchronous outcome of multiple worm wheels. It’s been used in automatic polishing cellular phone shell and other equipments
Servo worm gear systems 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,leading to tooth thickness gradual transformation,To enable you to approach worm shaft and modify backlash.

Low backlash Features :

— Worm gear gyration backlash could 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 band couplings : reliable without backlash.

Applications :

Precision rotary motion

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

Precision Indexing device

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

Speed changing situations

— Reducing the noise and the impact that’s due to speed change.
— Cutting down the worm abrasion that is due to speed changes.
Low rotation Make choice :

The next headings contain information on essential factors for selection and correct utilization of gearbox.
For certain data on the gearbox array,start to see the relevant chapters.
OUTPUT TORQUE
1、Rated output torque
Mn2 [Nm]
The torque that can be transmitted consistently 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 significantly less than torque Mn2 the gearbox under research is rated for.
3、Calculated torque
Mc2 [Nm]
Computational torque value to be used when selecting the gearbox. It really is calculated considering the needed torque Mr2 and service point fs, as per the relationship here after:
POWER
1、Rated input power
Pn1 [kW]
The parameter can be found 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 could be calculated with the next formulas:
EFFICIENCY
Efficiency is a good parameter which has a major effect on the sizing of certain applications, and basically will depend on gear pair designelements.
The mesh data 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 in and reaches the working temperature.
1、Dynamic efficiency
[ηd]
The dynamic efficiency may be 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 this is generally certainly not significant issue for helical gears, it may be instead critical when selecting worm gearmotors operating under intermittent duty.
SERVICE FACTOR [ fs ]
The service factor (fs ) is determined by the operating conditions the gearbox is subjected to the parameters that require to be taken under consideration to select the most satisfactory servies factor effectively comprise:
1. type of load of the managed machine : A – B – C
2. length of daily operating time: hours/day(△)
3. start-up rate of recurrence: starts/hour (*)
TYPE OF LOAD: A good – uniform, fa≤0.3
B – moderate shocks, fa≤3
C – major shocks, fa≤10
fa=Je/Jm
–Je(kgm2) minute of the external inertia reduced at the travel shaft
–Jm(kgm2) second of inertia of motor
–If fa>10 please contact our Technical Service
A -Screw feeders for light resources, fans, assembly lines, conveyor belts for light materials, tiny mixers, lifts, cleaning equipment, fillers, control machines.
B -Winding gadgets, woodworking machine feeders, things lifts, balancers,threading machines, medium mixers, conveyor belts for large materials,winches, sliding doors, fertilizer scrapers, packing equipment, concrete mixers, crane mechanisms, milling cutters, folding machines, equipment pumps.
C -Mixers for heavy supplies, shears, presses, centrifuges, rotating helps, winches and lifts for hefty materials, grinding lathes, natural stone mills, bucket elevators, drilling machines, hammer mills, cam presses, folding devices, turntables, tumbling barrels, vibrators, shredders.
series has a 90 degree suggestions via helical bevel gear,and its giant tapered roller bearings also produce it ideal for great radial and axial forces. PAR right angle reducer features an exceptionally short, light but rigid housing and total compatibility with standard engine adapters.PAR right angle planetary gearbox combines the benefits of a compact right angle gearbox and those of a conventional 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 action control applications wherein the power flow needs to be redirected. So it can help users to save the running cost and increase the transmission efficiency. The input flange measurements of PAR correct angle gearbox is available to be customized, consequently, it is appropriate for any brands of the servo stepper motors, motors and brushless DC motors.
