Low backlash right angle servo worm reducer
high precision worm equipment is an ideal replacement for precision planetary gearbox,the gear manufacturer can substantially reduce the price tag on using precision planetary gearbox
The designer’s ideal solution is to rotate 90 degrees to set up the servo motor get systems
Worm shaft in series could be driven by a single motor to achieve synchronous productivity of multiple worm tires. It has been used in automated 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.Left and right flank of worm shaft working with different lead angle,causing tooth thickness gradual change,To be able to maneuver worm shaft and change backlash.
Low backlash Features :
— Worm gear 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 band couplings : reliable without backlash.
Precision rotary motion
— Reducing the sound and vibration that’s caused by the strain change and the switch of cutting force.
— reducing the sound and impact that’s due to the corotation and reverse.
— By lowering worm abrasion.
— Increasing worm output response velocity .
Precision Indexing device
— CNC machine, assembly brand, cutting machine, transmitting lines, etc.
— Indexing device,accurate browsing mechanism require accurate movement occasions .
Speed changing situations
— Reducing the sound and the impact that is caused by speed change.
— Reducing 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 usage of gearbox.
For particular data on the gearbox range,start to see the relevant chapters.
1、Rated output torque
The torque which can be transmitted continuously through the output shaft, with the gear unit operated under a service factor fs = 1.
The torque demand based on application requirement. It is suggested to be add up to or less than torque Mn2 the gearbox under study is rated for.
Computational torque value to be used when selecting the gearbox. It really is calculated considering the required 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 that can be safely transmitted to the gearbox, predicated on input speed n1 and service factor fs= 1.
2、Rated output power
This value may be the power transmitted at gearbox output. it usually is calculated with the next formulas:
Efficiency is a good parameter that includes a major effect 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 found 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 at start-up of the gearbox. Although this is generally not significant point for helical gears, it could be instead critical when choosing 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 satisfactory servies factor appropriately comprise:
1. type of load of the managed machine : A – B – C
2. length of daily operating time: hours/day(△)
3. start-up regularity: starts/hour (*)
TYPE OF LOAD: A – uniform, fa≤0.3
B – average shocks, fa≤3
C – large shocks, fa≤10
–Je(kgm2) second of the external 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 suggestions via helical bevel gear,and its giant tapered roller bearings also make it ideal for high radial and axial forces. PAR right angle reducer features an extremely short, light however rigid housing and total compatibility with standard electric motor adapters.PAR right angle planetary gearbox combines the features of a compact right position gearbox and the ones 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 action control applications wherein the energy flow must be redirected. So that it can support users to save the running expense and improve the transmission effectiveness. The input flange dimensions of PAR proper angle gearbox is available to be customized, so, it is appropriate for any brands of the servo motors, brushless DC motors and stepper motors.
