Low backlash right position servo worm reducer
high precision worm gear is an ideal replacement for precision planetary gearbox,the gear manufacturer may substantially reduce the price of using precision planetary gearbox
The designer’s ideal solution is to rotate 90 degrees to install the servo motor get systems
Worm shaft found in series can be driven by a single motor to attain synchronous output of multiple worm wheels. It has been used in programmed polishing cellular phone shell and other equipments
Servo worm gear units have three types : 45 – 50 – 55 – 63 – 75 – 90 ,with dual lead worm drive.Left and best flank of worm shaft using different lead angle,leading to tooth thickness gradual change,To enable you to approach worm shaft and change backlash.
Low backlash Features :
— Worm gear 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.
Precision rotary motion
— Reducing the noises and vibration that’s caused by the load change and the modification of cutting force.
— reducing the noise and impact that’s caused by the corotation and reverse.
— By cutting down worm abrasion.
— Increasing worm output response swiftness .
Precision Indexing device
— CNC machine, assembly brand, cutting machine, transmitting lines, etc.
— Indexing device,accurate reading mechanism require accurate movements occasions .
Speed changing situations
— Reducing the noise 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 next headings contain information on essential elements for selection and correct make use of gearbox.
For certain data on the gearbox array,see the relevant chapters.
1、Rated output torque
The torque which can be transmitted constantly 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 equal to or significantly less than torque Mn2 the gearbox under study is rated for.
Computational torque value to be utilized when choosing the gearbox. It really is calculated considering the required torque Mr2 and service point fs, as per the relationship here after:
1、Rated input power
The parameter are available in the gearbox rating charts and represents the KW that 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 is usually calculated with the next formulas:
Efficiency is a good parameter which has 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.
Understand that these values are only achieved after the unit features 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 at start-up of the gearbox. Although that is generally not significant factor for helical gears, it may be instead critical when selecting 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 under consideration to choose the most satisfactory servies factor correctly comprise:
1. type of load of the managed machine : A – B – C
2. length of daily functioning 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
–Je(kgm2) instant of the exterior inertia reduced at the drive shaft
–Jm(kgm2) instant of inertia of motor
–If fa>10 please contact our Technical Service

series has a 90 degree type via helical bevel gear,and its good sized tapered roller bearings also try to make it ideal for superior radial and axial forces. PAR right angle reducer features an exceptionally short, light however rigid housing and complete compatibility with standard motor adapters.PAR right position planetary gearbox combines the benefits of a compact right position gearbox and those of a typical planetary gearbox.Highest Accuracy, Highest Torque and Calm Operation are given 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 it can help users to save lots of the running cost and improve the transmission productivity. The input flange dimensions of PAR right angle gearbox is available to be customized, as a result, it is compatible with any brands of the servo brushless DC motors, stepper motors and motors.
