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 drive systems
Worm shaft in series can be driven by 1 motor to attain synchronous outcome of multiple worm wheels. It has been used in automated polishing cellular phone shell and other equipments
Servo worm gear devices have three types : 45 – 50 – 55 – 63 – 75 – 90 ,with dual business lead worm drive.Left and best suited flank of worm shaft using different lead angle,causing tooth thickness gradual modification,To be able to approach worm shaft and adapt backlash.
Low backlash Features :
— Worm equipment gyration backlash could 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.
Precision rotary motion
— Reducing the noise and vibration that’s caused by the load change and the transformation of cutting force.
— reducing the noises and impact that’s due to the corotation and reverse.
— By reducing worm abrasion.
— Increasing worm output response swiftness .
Precision Indexing device
— CNC machine, assembly collection, cutting machine, transmission lines, etc.
— Indexing device,accurate reading mechanism require accurate activity occasions .
Speed changing situations
— Reducing the noise and the impact that’s due to speed change.
— Reducing the worm abrasion that is due to speed changes.
Low rotation Make decision :
The next headings contain information on essential components for selection and correct make use of gearbox.
For particular data on the gearbox array,start to see the relevant chapters.
1、Rated output torque
The torque which can be transmitted consistently through the output shaft, with the apparatus unit operated under something factor fs = 1.
The torque demand based on application requirement. It is suggested to be add up 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 needed torque Mr2 and service component fs, as per the relationship here after:
1、Rated input power
The parameter are available 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 is the power transmitted at gearbox output. it might be calculated with the next formulas:
Efficiency is a good parameter that includes a major impact on the sizing of certain applications, and basically will depend on gear pair designelements.
The mesh info table on page 9 shows dynamic efficiency (n1=1400)and static efficiency values.
Remember that these values are just achieved following the unit offers been run in and is at the working temperature.
The dynamic efficiency is 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 certainly not significant point for helical gears, it can be instead critical when choosing worm gearmotors functioning under intermittent duty.
SERVICE FACTOR [ fs ]
The service factor (fs ) is determined by the operating conditions the gearbox is subjected to the parameters that need to be taken into consideration to select the most enough servies factor effectively comprise:
1. kind of load of the operated machine : A – B – C
2. length of daily operating time: hours/day(△)
3. start-up rate of recurrence: starts/hour (*)
TYPE OF LOAD: A – uniform, fa≤0.3
B – moderate shocks, fa≤3
C – large shocks, fa≤10
–Je(kgm2) minute of the external inertia reduced at the drive shaft
–Jm(kgm2) moment of inertia of motor
–If fa>10 please contact our Technical Service

series includes a 90 degree input via helical bevel gear,and its giant tapered roller bearings also produce it ideal for great radial and axial forces. PAR right angle reducer features an extremely short, light however rigid housing and complete compatibility with standard motor adapters.PAR right position planetary gearbox combines the features of a compact right position gearbox and the ones of a conventional planetary gearbox.Highest Accuracy, 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 movement control applications wherein the power flow needs to be redirected. So it can support users to save the running cost and enhance the transmission performance. The input flange sizes of PAR correct angle gearbox is open to be customized, consequently, it is compatible with any makes of the servo stepper motors, motors and brushless DC motors.
