Low backlash right angle servo worm reducer

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

The designer’s ideal solution is to rotate 90 degrees to set up the servo motor travel systems

Worm shaft found in series could be driven by a single motor to attain synchronous result of multiple worm wheels. It’s been used in automatic polishing mobile phone shell and other equipments
Servo worm gear models have three types : 45 – 50 – 55 – 63 – 75 – 90 ,with dual business lead worm drive.Still left and best suited flank of worm shaft working with different lead angle,causing tooth thickness gradual switch,So that you can approach worm shaft and modify backlash.

Low backlash Features :

— Worm equipment 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 band couplings : reliable without backlash.

Applications :

Precision rotary motion

— Reducing the sound and vibration that’s caused by the load change and the switch of cutting force.
— reducing the noises and impact that’s caused by the corotation and reverse.
— By lessening worm abrasion.
— Increasing worm output response speed .

Precision Indexing device

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

Speed changing situations

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

The following headings contain information on essential elements for selection and correct use of gearbox.
For specific data on the gearbox array,start to see the relevant chapters.
OUTPUT TORQUE
1、Rated output torque
Mn2 [Nm]
The torque that can be transmitted continuously 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 recommended to be equal to or significantly less than torque Mn2 the gearbox under analysis is rated for.
3、Calculated torque
Mc2 [Nm]
Computational torque value to be used when selecting the gearbox. It is calculated considering the expected torque Mr2 and service issue 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 really is calculated with the following formulas:
EFFICIENCY
Efficiency is a good parameter that includes a major affect on the sizing of certain applications, and basically is determined by 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 reaches the working temperature.
1、Dynamic efficiency
[ηd]
The dynamic efficiency may be 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 choosing worm gearmotors functioning under intermittent duty.
SERVICE FACTOR [ fs ]
The service factor (fs ) will depend on the operating conditions the gearbox is put through the parameters that need to be taken into consideration to choose the most adequate servies factor properly comprise:
1. type of load of the managed equipment : A – B – C
2. length of daily operating time: hours/day(△)
3. start-up regularity: starts/hour (*)
TYPE OF LOAD: A good – uniform, fa≤0.3
B – average shocks, fa≤3
C – heavy 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 -Screw feeders for light supplies, supporters, assembly lines, conveyor belts for light materials, tiny mixers, lifts, cleaning equipment, fillers, control machines.
B -Winding products, woodworking machine feeders, products lifts, balancers,threading devices, medium mixers, conveyor belts for large materials,winches, sliding doors, fertilizer scrapers, packing devices, concrete mixers, crane mechanisms, milling cutters, folding machines, gear pumps.
C -Mixers for heavy elements, shears, presses, centrifuges, rotating works with, winches and lifts for hefty materials, grinding lathes, stone mills, bucket elevators, drilling machines, hammer mills, cam presses, folding machines, turntables, tumbling barrels, vibrators, shredders.
series has a 90 degree input via helical bevel equipment,and its giant tapered roller bearings also get it ideal for large radial and axial forces. PAR right angle reducer features an exceptionally short, light yet rigid housing and full compatibility with standard motor adapters.PAR right position planetary gearbox combines the benefits of a compact right angle gearbox and the ones of a conventional planetary gearbox.Highest Precision, 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 must be redirected. So that it can help users to save the running expense and increase the transmission efficiency. The input flange sizes of PAR proper angle gearbox is available to be customized, subsequently, it is compatible with any makes of the servo brushless DC motors, motors and stepper motors.
