Low backlash right angle servo worm reducer

Low backlash right angle servo worm reducer
high precision worm gear is an ideal replacement 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 install the servo motor drive systems

Worm shaft in series could be driven by 1 motor to accomplish synchronous end result of multiple worm tires. It has been used in automatic polishing mobile phone shell and other equipments
Servo worm gear systems have three types : 45 – 50 – 55 – 63 – 75 – 90 ,with dual lead worm drive.Left and ideal flank of worm shaft working with different lead angle,leading to tooth thickness gradual switch,To enable you to maneuver worm shaft and adjust backlash.

Low backlash Features :

— Worm equipment gyration backlash could be adjusted to 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’s caused by the strain change and the modification of cutting force.
— reducing the sound and impact that is due to the corotation and reverse.
— By reducing worm abrasion.
— Increasing worm output response velocity .

Precision Indexing device

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

Speed changing situations

— Reducing the sound and the impact that’s due to speed change.
— Cutting down the worm abrasion that is due to 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 continually through the output shaft, with the gear unit operated under a service 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 utilized when selecting the gearbox. It is calculated considering the required 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 is usually calculated with the following 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.
Understand that these values are just 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 issue for helical gears, it can be instead critical when selecting worm gearmotors operating under intermittent duty.
SERVICE FACTOR [ fs ]
The service factor (fs ) will depend 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 properly comprise:
1. kind of load of the managed equipment : A – B – C
2. length of daily working time: hours/day(△)
3. start-up rate of recurrence: starts/hour (*)
TYPE OF LOAD: A – uniform, fa≤0.3
B – average shocks, fa≤3
C – major shocks, fa≤10
fa=Je/Jm
–Je(kgm2) minute of the external inertia reduced at the drive shaft
–Jm(kgm2) second of inertia of motor
–If fa>10 please contact our Technical Service
A good -Screw feeders for light supplies, followers, assembly lines, conveyor belts for light materials, small mixers, lifts, cleaning devices, fillers, control machines.
B -Winding equipment, woodworking machine feeders, things lifts, balancers,threading devices, medium mixers, conveyor belts for large materials,winches, sliding doorways, fertilizer scrapers, packing equipment, concrete mixers, crane mechanisms, milling cutters, folding machines, gear pumps.
C -Mixers for heavy products, shears, presses, centrifuges, rotating supports, winches and lifts for large materials, grinding lathes, rock mills, bucket elevators, drilling devices, hammer mills, cam presses, folding equipment, turntables, tumbling barrels, vibrators, shredders.
series has a 90 degree input via helical bevel gear,and its large tapered roller bearings also try to make it ideal for superior radial and axial forces. PAR right position reducer features an exceptionally short, light but rigid housing and total compatibility with standard motor adapters.PAR right angle planetary gearbox combines the advantages of a compact right angle gearbox and the ones of a typical planetary gearbox.Highest Accuracy, Highest Torque and Quiet 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 needs to be redirected. So it can help users to save the running expense and improve the transmission productivity. The input flange measurements of PAR right angle gearbox is available to be customized, so, it is compatible with any makes of the servo motors, stepper motors and brushless DC motors.
