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

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

Worm shaft found in series can be driven by 1 motor to attain synchronous outcome of multiple worm tires. It’s been used in automated polishing cellular 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,leading to tooth thickness gradual switch,So that you can move worm shaft and modify 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 sound and vibration that is caused by the strain change and the change of cutting force.
— reducing the noise and impact that is caused by the corotation and reverse.
— By cutting down worm abrasion.
— Increasing worm output response swiftness .

Precision Indexing device

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

Speed changing situations

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

The following headings contain information on essential factors for selection and correct make use of gearbox.
For particular data on the gearbox spectrum,start to see the relevant chapters.
OUTPUT TORQUE
1、Rated output torque
Mn2 [Nm]
The torque that can be transmitted continuously through the output shaft, with the apparatus 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 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 selecting the gearbox. It 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 are available in the gearbox rating charts and represents the KW that 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 is the power transmitted at gearbox output. it really is calculated with the following formulas:
EFFICIENCY
Efficiency is a parameter which has a major impact 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 offers been run found in and is at 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 at start-up of the gearbox. Although that is generally not significant element for helical gears, it could be instead critical when choosing worm gearmotors working 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 select the most satisfactory servies factor correctly comprise:
1. type of load of the operated 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 – moderate shocks, fa≤3
C – major shocks, fa≤10
fa=Je/Jm
–Je(kgm2) second 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 products, enthusiasts, assembly lines, conveyor belts for light materials, small mixers, lifts, cleaning machines, fillers, control machines.
B -Winding products, woodworking machine feeders, items lifts, balancers,threading machines, medium mixers, conveyor belts for major materials,winches, sliding doorways, fertilizer scrapers, packing devices, cement mixers, crane mechanisms, milling cutters, folding machines, equipment pumps.
C -Mixers for heavy supplies, shears, presses, centrifuges, rotating works with, winches and lifts for large 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 input via helical bevel gear,and its good sized tapered roller bearings also help to make 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 electric motor adapters.PAR right angle planetary gearbox combines the advantages of a compact right position gearbox and the ones of a typical planetary gearbox.Highest Precision, Highest Torque and Calm 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 power flow has to be redirected. So that it can help users to save lots of the running price and enhance the transmission performance. The input flange sizes of PAR correct angle gearbox is available to be customized, therefore, it is compatible with any makes of the servo motors, brushless DC motors and stepper motors.
