Low backlash right position servo worm reducer
high precision worm gear is an ideal substitute 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 set up the servo motor drive systems

Worm shaft in series could be driven by one motor to accomplish synchronous output of multiple worm tires. 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 business lead worm drive.Left and right flank of worm shaft working with different lead angle,causing tooth thickness gradual switch,To be able to maneuver worm shaft and modify backlash.

Low backlash Features :

— Worm gear gyration backlash can be adjusted to less than 1 arc.
— Reducer can 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 due to the corotation and reverse.
— By cutting down worm abrasion.
— Increasing worm output response velocity .

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 elements for selection and correct use of gearbox.
For particular data on the gearbox range,start to see the relevant chapters.
OUTPUT TORQUE
1、Rated output torque
Mn2 [Nm]
The torque that 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 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 required torque Mr2 and service issue fs, as per the partnership 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 may be 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 depends upon 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 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 point for helical gears, it may be instead critical when selecting worm gearmotors working 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 into consideration to choose the most enough servies factor properly comprise:
1. kind of load of the managed equipment : A – B – C
2. length of daily working 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) moment of the external inertia reduced at the travel shaft
–Jm(kgm2) second of inertia of motor
–If fa>10 please contact our Technical Service

series includes a 90 degree input via helical bevel equipment,and its good sized tapered roller bearings also help to make 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 benefits of a compact right angle gearbox and the ones 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 it can help users to save lots of the running expense and enhance the transmission efficiency. The input flange dimensions of PAR right angle gearbox is available to be customized, subsequently, it is appropriate for any makes of the servo brushless DC motors, stepper motors and motors.
