Low backlash right angle servo worm reducer
high precision worm equipment is an ideal replacement 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 install the servo motor get systems
Worm shaft found in series could be driven by one motor to achieve synchronous outcome of multiple worm tires. 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 business lead worm drive.Left and best flank of worm shaft working with different lead angle,leading to tooth thickness gradual modification,So that you can move worm shaft and change backlash.
Low backlash Features :
— Worm equipment 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 sound and vibration that’s caused by the load change and the change of cutting force.
— reducing the noises and impact that is caused by the corotation and reverse.
— By lessening 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 motion occasions .
Speed changing situations
— Reducing the sound and the impact that is caused by speed change.
— Cutting down the worm abrasion that’s caused by speed changes.
Low rotation Make decision :
The next headings contain information on essential components for selection and correct use of gearbox.
For particular data on the gearbox spectrum,see the relevant chapters.
1、Rated output torque
The torque which can be transmitted continually through the output shaft, with the apparatus unit operated under something factor fs = 1.
The torque demand predicated on application requirement. It is suggested to be add up to or significantly less than torque Mn2 the gearbox under analysis is rated for.
Computational torque value to be used when selecting the gearbox. It really is calculated considering the expected 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 usually is calculated with the next formulas:
Efficiency is a parameter which has a major influence 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 just achieved following the unit offers been run found in and reaches 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 in start-up of the gearbox. Although that is generally certainly not significant component for helical gears, it could be instead critical when choosing worm gearmotors functioning 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 under consideration to choose the most satisfactory servies factor appropriately comprise:
1. kind of load of the managed machine : A – B – C
2. length of daily functioning time: hours/day(△)
3. start-up regularity: starts/hour (*)
TYPE OF LOAD: A – uniform, fa≤0.3
B – moderate shocks, fa≤3
C – major shocks, fa≤10
–Je(kgm2) moment of the external inertia reduced at the get shaft
–Jm(kgm2) instant of inertia of motor
–If fa>10 please contact our Technical Service

series includes a 90 degree suggestions via helical bevel gear,and its good sized tapered roller bearings also get it ideal for high radial and axial forces. PAR right angle reducer features an exceptionally short, light however rigid housing and full compatibility with standard electric motor adapters.PAR right position planetary gearbox combines the features of a compact right angle gearbox and the ones of a typical planetary gearbox.Highest Accuracy, Highest Torque and Quiet Operation are given 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 energy flow should be redirected. So that it can support users to save the running expense and enhance the transmission efficiency. The input flange dimensions of PAR proper angle gearbox is available to be customized, therefore, it is appropriate for any brands of the servo stepper motors, motors and brushless DC motors.
