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

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

Worm shaft in series could be driven by one motor to accomplish synchronous output of multiple worm wheels. It has been used in automatic polishing cellular phone shell and other equipments
Servo worm gear devices have three types : 45 – 50 – 55 – 63 – 75 – 90 ,with dual lead worm drive.Left and best flank of worm shaft working with different lead angle,causing tooth thickness gradual switch,To enable you to move 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 sound and vibration that is caused by the strain change and the change of cutting force.
— reducing the sound and impact that’s caused by the corotation and reverse.
— By reducing worm abrasion.
— Increasing worm output response quickness .

Precision Indexing device

— CNC machine, assembly range, cutting machine, transmitting lines, etc.

Speed changing situations

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

The next headings contain information on essential factors for selection and correct make use of gearbox.
For particular data on the gearbox range,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 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 utilized when choosing the gearbox. It really is calculated considering the required 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 may be the power transmitted at gearbox output. it might be calculated with the next formulas:
EFFICIENCY
Efficiency is a parameter that includes a major affect 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 has been run 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 in start-up of the gearbox. Although that is generally not significant factor for helical gears, it may 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 require to be taken into consideration to select the most sufficient servies factor properly comprise:
1. kind of load of the operated machine : A – B – C
2. length of daily operating time: hours/day(△)
3. start-up frequency: starts/hour (*)
TYPE OF LOAD: A good – uniform, fa≤0.3
B – average shocks, fa≤3
C – serious shocks, fa≤10
fa=Je/Jm
–Je(kgm2) second of the exterior inertia reduced at the travel shaft
–Jm(kgm2) point in time of inertia of motor
–If fa>10 please contact our Technical Service

series includes a 90 degree input via helical bevel gear,and its large tapered roller bearings also produce it ideal for superior radial and axial forces. PAR right angle reducer features an exceptionally short, light yet rigid housing and total compatibility with standard motor adapters.PAR right position planetary gearbox combines the benefits of a compact right angle gearbox and those of a conventional 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 motion control applications wherein the power flow must be redirected. So that it can support users to save lots of the running price and enhance the transmission efficiency. The input flange dimensions of PAR correct angle gearbox is open to be customized, so, it is compatible with any brands of the servo motors, stepper motors and brushless DC motors.
