Low backlash right position servo worm reducer
high precision worm gear 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 install the servo motor get systems
Worm shaft found in series can be driven by 1 motor to achieve synchronous productivity of multiple worm tires. It’s been used in programmed 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.Still left and right flank of worm shaft working with different lead angle,leading to tooth thickness gradual transformation,To enable you to approach worm shaft and modify backlash.
Low backlash Features :
— Worm gear gyration backlash could be adjusted to less than 1 arc.
— Reducer can 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 strain change and the transformation of cutting force.
— reducing the noise and impact that’s due to the corotation and reverse.
— By cutting down worm abrasion.
— Increasing worm output response acceleration .
Precision Indexing device
— CNC machine, assembly line, cutting machine, transmission lines, etc.
— Indexing device,accurate studying mechanism require accurate movement occasions .
Speed changing situations
— Reducing the sound and the impact that’s caused by speed change.
— Lessening the worm abrasion that is due to speed changes.
Low rotation Make decision :
The next headings contain information on essential factors for selection and correct make use of gearbox.
For particular data on the gearbox range,see the relevant chapters.
1、Rated output torque
The torque that can be transmitted constantly through the output shaft, with the apparatus unit operated under something factor fs = 1.
The torque demand predicated on application requirement. It is recommended to be equal to or significantly less than torque Mn2 the gearbox under analysis is rated for.
Computational torque value to be utilized when selecting the gearbox. It is calculated considering the required torque Mr2 and service element fs, as per the partnership 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 can be calculated with the following formulas:
Efficiency is a parameter that includes a major effect 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 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 not significant element for helical gears, it can be instead critical when selecting worm gearmotors operating 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 satisfactory servies factor appropriately comprise:
1. type of load of the managed equipment : 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 – major shocks, fa≤10
–Je(kgm2) instant of the external inertia reduced at the drive shaft
–Jm(kgm2) point in time 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 help to make it ideal for large radial and axial forces. PAR right angle reducer features an extremely short, light yet 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 those 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 needs to be redirected. So it can support users to save the running cost and enhance the transmission productivity. The input flange dimensions of PAR correct angle gearbox is available to be customized, accordingly, it is compatible with any makes of the servo brushless DC motors, motors and stepper motors.
