Low backlash right position servo worm reducer
high precision worm gear is an ideal substitute for precision planetary gearbox,the equipment manufacturer may 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 can be driven by 1 motor to accomplish synchronous result of multiple worm tires. It’s been used in computerized polishing cellular phone shell and other equipments
Servo worm gear systems have three types : 45 – 50 – 55 – 63 – 75 – 90 ,with dual business lead worm drive.Left and best flank of worm shaft using different lead angle,leading to tooth thickness gradual switch,To enable you to approach worm shaft and adapt backlash.
Low backlash Features :
— Worm equipment gyration backlash can be adjusted to significantly less than 1 arc.

Low rotation Make decision :
The next headings contain information on essential factors for selection and correct use of gearbox.
For specific data on the gearbox collection,start to see the relevant chapters.
1、Rated output torque
The torque that can be transmitted constantly through the output shaft, with the gear unit operated under something factor fs = 1.
The torque demand predicated on application requirement. It is suggested to be equal to or less than torque Mn2 the gearbox under review is rated for.
Computational torque value to be utilized when choosing the gearbox. It is calculated considering the needed 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 which 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 following formulas:
Efficiency is a parameter which has a major affect on the sizing of certain applications, and basically is determined by 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 has 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 in start-up of the gearbox. Although that is generally certainly not significant aspect for helical gears, it may be instead critical when selecting worm gearmotors working under intermittent duty.
SERVICE FACTOR [ fs ]
The service factor (fs ) depends on the operating conditions the gearbox is subjected to the parameters that need to be taken under consideration to choose the most adequate servies factor effectively comprise:
1. kind of load of the operated equipment : A – B – C
2. length of daily working time: hours/day(△)
3. start-up frequency: starts/hour (*)
TYPE OF LOAD: A good – uniform, fa≤0.3
B – moderate shocks, fa≤3
C – major shocks, fa≤10
–Je(kgm2) point in time of the external inertia reduced at the get shaft
–Jm(kgm2) moment of inertia of motor
–If fa>10 please contact our Technical Service

series includes a 90 degree source via helical bevel equipment,and its good sized tapered roller bearings also produce it ideal for large radial and axial forces. PAR right angle reducer features an exceptionally short, light but rigid housing and full compatibility with standard motor adapters.PAR right position planetary gearbox combines the advantages of a compact right angle gearbox and those of a conventional 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 motion control applications wherein the energy flow has to be redirected. So it can help users to save lots of the running cost and enhance the transmission productivity. The input flange sizes of PAR right angle gearbox is open to be customized, therefore, it is compatible with any makes of the servo brushless DC motors, stepper motors and motors.
