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 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 can be driven by a single motor to accomplish synchronous output of multiple worm wheels. It’s been used in automatic polishing mobile phone shell and other equipments
Servo worm gear devices have three types : 45 – 50 – 55 – 63 – 75 – 90 ,with dual lead worm drive.Still left and right flank of worm shaft using different lead angle,causing tooth thickness gradual change,To be able to approach worm shaft and adapt backlash.

Low backlash Features :

— Worm gear gyration backlash could be adjusted to significantly 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 noises and vibration that is caused by the strain change and the modification of cutting force.
— reducing the noise and impact that’s due to the corotation and reverse.
— By lowering worm abrasion.
— Increasing worm output response quickness .

Precision Indexing device

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

Speed changing situations

— Reducing the noise and the impact that’s due to speed change.
— Reducing 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 usage of gearbox.
For certain data on the gearbox collection,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 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 less than torque Mn2 the gearbox under research is rated for.
3、Calculated torque
Mc2 [Nm]
Computational torque value to be utilized when choosing the gearbox. It is calculated considering the needed torque Mr2 and service aspect 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 following formulas:
EFFICIENCY
Efficiency is a good parameter that includes a major effect on the sizing of certain applications, and basically depends on gear pair designelements.
The mesh data table on page 9 shows dynamic efficiency (n1=1400)and static efficiency values.
Remember that these values are only achieved after the unit features 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 put through the parameters that require to be taken into consideration to choose the most sufficient servies factor correctly comprise:
1. type 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 – large shocks, fa≤10
fa=Je/Jm
–Je(kgm2) minute of the exterior inertia reduced at the travel shaft
–Jm(kgm2) minute of inertia of motor
–If fa>10 please contact our Technical Service

series has a 90 degree source via helical bevel equipment,and its giant tapered roller bearings also produce it ideal for great radial and axial forces. PAR right position reducer features an extremely short, light but rigid housing and complete 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 Precision, Highest Torque and Calm Operation are provided 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 it can help users to save lots of the running cost and increase the transmission productivity. The input flange sizes of PAR right angle gearbox is open to be customized, so, it is compatible with any makes of the servo brushless DC motors, stepper motors and motors.
