Low backlash right position servo worm reducer
high precision worm equipment is an ideal substitute for precision planetary gearbox,the gear manufacturer may 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 in series could be driven by one motor to attain synchronous productivity 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 working with different lead angle,leading to tooth thickness gradual switch,To enable you to move worm shaft and change backlash.
Low backlash Features :
— Worm equipment gyration backlash can be adjusted to significantly less than 1 arc.
— Reducer can be re-adjusted the gap after using .
— Input with coupling : reliable without backlash .

— By lowering worm abrasion.
— Increasing worm output response rate .
Precision Indexing device
— CNC machine, assembly range, cutting machine, transmitting lines, etc.
— Indexing device,accurate browsing mechanism require accurate movement occasions .
Speed changing situations
— Reducing the noise and the impact that’s caused by speed change.
— Reducing the worm abrasion that is caused by speed changes.
Low rotation Make decision :
The following headings contain information on essential factors for selection and correct use of gearbox.
For certain data on the gearbox assortment,see the relevant chapters.
1、Rated output torque
The torque that can be transmitted consistently through the output shaft, with the gear unit operated under a service factor fs = 1.
The torque demand predicated on application requirement. It is suggested to be equal to or significantly less than torque Mn2 the gearbox under study is rated for.
Computational torque value to be used when choosing the gearbox. It really is calculated considering the expected torque Mr2 and service component fs, as per the partnership here after:
1、Rated input power
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
This value may be the power transmitted at gearbox output. it could be calculated with the next formulas:
Efficiency is a parameter that includes a major impact 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 just achieved following the unit has been run in and reaches the working temperature.
The dynamic efficiency may be the relationship of power delivered at output shaft P2 to power applied at input shaft P1:
Efficiency obtained in start-up of the gearbox. Although that is generally not really significant aspect for helical gears, it can be instead critical when choosing worm gearmotors working under intermittent duty.
SERVICE FACTOR [ fs ]
The service factor (fs ) will depend on the operating conditions the gearbox is subjected to the parameters that need to be taken into consideration to choose the most enough servies factor appropriately comprise:
1. kind of load of the managed machine : A – B – C
2. length of daily working 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
–Je(kgm2) minute of the exterior inertia reduced at the travel shaft
–Jm(kgm2) second of inertia of motor
–If fa>10 please contact our Technical Service
A good -Screw feeders for light supplies, fans, assembly lines, conveyor belts for light materials, tiny mixers, lifts, cleaning devices, fillers, control machines.
B -Winding gadgets, woodworking machine feeders, things lifts, balancers,threading devices, moderate mixers, conveyor belts for major materials,winches, sliding doorways, fertilizer scrapers, packing devices, cement mixers, crane mechanisms, milling cutters, folding machines, gear pumps.
C -Mixers for heavy supplies, shears, presses, centrifuges, rotating works with, winches and lifts for heavy materials, grinding lathes, stone mills, bucket elevators, drilling equipment, hammer mills, cam presses, folding machines, turntables, tumbling barrels, vibrators, shredders.
series includes a 90 degree insight via helical bevel equipment,and its giant tapered roller bearings also try to make it ideal for great radial and axial forces. PAR right angle reducer features an exceptionally short, light but rigid housing and full compatibility with standard electric motor adapters.PAR right angle planetary gearbox combines the advantages of a compact right angle gearbox and those 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 energy flow must be redirected. So that it can help users to save lots of the running cost and enhance the transmission performance. The input flange dimensions of PAR proper angle gearbox is open to be customized, accordingly, it is appropriate for any makes of the servo stepper motors, brushless DC motors and motors.
