Low backlash right position servo worm reducer
high precision worm gear is an ideal substitute for precision planetary gearbox,the equipment manufacturer can substantially reduce the price tag on 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 could be driven by one motor to attain synchronous result of multiple worm tires. It has been used in automated polishing mobile 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 right flank of worm shaft working with different lead angle,causing tooth thickness gradual modification,To be able to maneuver worm shaft and adapt backlash.

Low backlash Features :

— Worm gear gyration backlash can be adjusted to significantly 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 noises and vibration that is caused by the strain change and the switch of cutting force.
— reducing the sound and impact that’s caused by the corotation and reverse.
— By lessening worm abrasion.
— Increasing worm output response rate .

Precision Indexing device

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

Speed changing situations

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

The following headings contain information on essential components for selection and correct use of gearbox.
For certain data on the gearbox selection,start to see the relevant chapters.
OUTPUT TORQUE
1、Rated output torque
Mn2 [Nm]
The torque which can be transmitted constantly through the output shaft, with the gear unit operated under something factor fs = 1.
2、Required torque
Mr2 [Nm]
The torque demand based on application requirement. It is recommended to be add up 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 issue 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, based 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 can be calculated with the next formulas:
EFFICIENCY
Efficiency is a parameter which has a major influence on the sizing of certain applications, and basically will depend on 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 following the unit features been run found in and is at 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 certainly not significant factor 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 require to be taken into consideration to select the most satisfactory servies factor properly comprise:
1. kind of load of the managed equipment : A – B – C
2. length of daily functioning time: hours/day(△)
3. start-up rate of recurrence: starts/hour (*)
TYPE OF LOAD: A – uniform, fa≤0.3
B – moderate shocks, fa≤3
C – heavy shocks, fa≤10
fa=Je/Jm
–Je(kgm2) instant of the external inertia reduced at the travel shaft
–Jm(kgm2) minute of inertia of motor
–If fa>10 please contact our Technical Service
A good -Screw feeders for light elements, admirers, assembly lines, conveyor belts for light materials, small mixers, lifts, cleaning machines, fillers, control machines.

series includes a 90 degree insight via helical bevel equipment,and its good sized tapered roller bearings also produce it ideal for superior radial and axial forces. PAR right angle reducer features an exceptionally short, light however 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 Precision, 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 motion control applications wherein the energy flow needs to be redirected. So that it can help users to save the running cost and increase the transmission efficiency. The input flange dimensions of PAR correct angle gearbox is available to be customized, subsequently, it is appropriate for any makes of the servo brushless DC motors, motors and stepper motors.
