Low backlash right angle servo worm reducer
high precision worm equipment is an ideal substitute for precision planetary gearbox,the equipment manufacturer can substantially reduce the price 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 found in series could be driven by a single motor to achieve synchronous productivity of multiple worm wheels. It has been used in automated 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 using different lead angle,causing tooth thickness gradual modification,To enable you to maneuver worm shaft and adjust backlash.
Low backlash Features :
— Worm gear gyration backlash can 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 noise and vibration that is caused by the load change and the change of cutting force.
— reducing the noise and impact that’s due to the corotation and reverse.
— By lessening worm abrasion.
— Increasing worm output response rate .
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 noise and the impact that’s caused by speed change.
— Lessening the worm abrasion that’s caused by speed changes.
Low rotation Make choice :
The next headings contain information on essential components for selection and correct use of gearbox.
For specific data on the gearbox selection,see the relevant chapters.
1、Rated output torque
The torque that can be transmitted continuously 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 less than torque Mn2 the gearbox under review is rated for.
Computational torque value to be used when choosing the gearbox. It really is calculated considering the needed torque Mr2 and service factor 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 may be the power transmitted at gearbox output. it can be calculated with the next formulas:
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 data 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 found in and is at 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 certainly not significant issue for helical gears, it could be instead critical when selecting worm gearmotors working under intermittent duty.
SERVICE FACTOR [ fs ]
The service factor (fs ) depends upon the operating conditions the gearbox is subjected to the parameters that need to be taken into consideration to select the most adequate servies factor effectively comprise:
1. type 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 – uniform, fa≤0.3
B – average shocks, fa≤3
C – heavy shocks, fa≤10
–Je(kgm2) point in time 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 equipment,and its large tapered roller bearings also produce it ideal for superior radial and axial forces. PAR right position reducer features an exceptionally short, light but rigid housing and full compatibility with standard engine adapters.PAR right position planetary gearbox combines the features of a compact right position gearbox and those 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 action control applications wherein the energy flow needs to be redirected. So that it can support users to save lots of the running expense and increase the transmission productivity. The input flange dimensions of PAR correct angle gearbox is available to be customized, therefore, it is compatible with any brands of the servo stepper motors, brushless DC motors and motors.
