Low backlash right angle servo worm reducer
high precision worm equipment is an ideal replacement for precision planetary gearbox,the equipment manufacturer can 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 drive systems

Worm shaft found in series could be driven by 1 motor to achieve synchronous result of multiple worm tires. It’s been used in programmed polishing mobile phone shell and other equipments
Servo worm gear units have three types : 45 – 50 – 55 – 63 – 75 – 90 ,with dual lead worm drive.Left and right flank of worm shaft working with different lead angle,causing tooth thickness gradual change,To be able to move worm shaft and adjust 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 sound and vibration that’s caused by the load change and the change of cutting force.
— reducing the sound and impact that is caused by the corotation and reverse.
— By lowering worm abrasion.
— Increasing worm output response acceleration .

Precision Indexing device

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

Speed changing situations

— Reducing the sound and the impact that’s due to speed change.
— Lowering the worm abrasion that’s caused by speed changes.
Low rotation Make decision :

The following headings contain information on essential components for selection and correct use of gearbox.
For specific 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 gear unit operated under something factor fs = 1.
2、Required torque
Mr2 [Nm]
The torque demand predicated on application requirement. It is suggested to be add up 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 really is calculated considering the needed torque Mr2 and service factor fs, as per the partnership here after:
POWER
1、Rated input power
Pn1 [kW]
The parameter are available in the gearbox rating charts and represents the KW which 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 may be the power transmitted at gearbox output. it can be calculated with the next formulas:
EFFICIENCY
Efficiency is a good 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.
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 at start-up of the gearbox. Although that is generally not really significant issue for helical gears, it might be instead critical when choosing worm gearmotors functioning under intermittent duty.
SERVICE FACTOR [ fs ]
The service factor (fs ) will depend on the operating conditions the gearbox is subjected to the parameters that require to be taken under consideration to select the most enough servies factor effectively comprise:
1. kind of load of the managed machine : A – B – C
2. length of daily operating time: hours/day(△)
3. start-up rate of recurrence: starts/hour (*)
TYPE OF LOAD: A good – uniform, fa≤0.3
B – moderate shocks, fa≤3
C – large shocks, fa≤10
fa=Je/Jm
–Je(kgm2) moment of the external inertia reduced at the drive shaft
–Jm(kgm2) instant of inertia of motor
–If fa>10 please contact our Technical Service
A good -Screw feeders for light elements, supporters, assembly lines, conveyor belts for light materials, little mixers, lifts, cleaning equipment, fillers, control machines.
B -Winding equipment, woodworking machine feeders, goods lifts, balancers,threading devices, medium mixers, conveyor belts for heavy materials,winches, sliding doors, fertilizer scrapers, packing machines, concrete mixers, crane mechanisms, milling cutters, folding machines, equipment pumps.
C -Mixers for heavy materials, shears, presses, centrifuges, rotating supports, winches and lifts for weighty materials, grinding lathes, rock mills, bucket elevators, drilling machines, hammer mills, cam presses, folding equipment, turntables, tumbling barrels, vibrators, shredders.
series has a 90 degree suggestions via helical bevel equipment,and its good sized tapered roller bearings also help to make it ideal for high radial and axial forces. PAR right position reducer features an exceptionally short, light but rigid housing and total compatibility with standard electric motor adapters.PAR right position planetary gearbox combines the benefits of a compact right position 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 action control applications wherein the energy flow needs to be redirected. So it can help users to save lots of the running price and increase the transmission efficiency. The input flange sizes of PAR proper angle gearbox is open to be customized, consequently, it is appropriate for any makes of the servo stepper motors, brushless DC motors and motors.
