Low backlash right position servo worm reducer
high precision worm equipment is an ideal replacement for precision planetary gearbox,the gear manufacturer can substantially reduce the price of using precision planetary gearbox
The designer’s ideal solution is to rotate 90 degrees to install the servo motor drive systems
Worm shaft in series can be driven by 1 motor to accomplish synchronous outcome of multiple worm tires. It has been used in automated polishing mobile phone shell and other equipments
Servo worm gear systems 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,leading to tooth thickness gradual transformation,To enable you to maneuver worm shaft and modify backlash.
Low backlash Features :

Low rotation Make decision :
The following headings contain information on essential components for selection and correct usage of gearbox.
For specific data on the gearbox range,start to see the relevant chapters.
1、Rated output torque
The torque which can be transmitted continuously through the output shaft, with the gear unit operated under a service 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 choosing the gearbox. It really is calculated considering the required torque Mr2 and service component 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, predicated 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 parameter which has a major affect on the sizing of certain applications, and basically will depend on 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 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 in start-up of the gearbox. Although this is generally not significant aspect for helical gears, it can be instead critical when selecting worm gearmotors functioning under intermittent duty.
SERVICE FACTOR [ fs ]
The service factor (fs ) depends upon the operating conditions the gearbox is put through the parameters that need to be taken under consideration to choose the most enough servies factor effectively comprise:
1. kind of load of the operated machine : A – B – C
2. length of daily operating 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 – serious shocks, fa≤10
–Je(kgm2) point in time of the external inertia reduced at the drive shaft
–Jm(kgm2) second of inertia of motor
–If fa>10 please contact our Technical Service

series includes a 90 degree input via helical bevel gear,and its giant tapered roller bearings also help to make it ideal for superior radial and axial forces. PAR right position reducer features an extremely short, light yet rigid housing and total compatibility with standard motor adapters.PAR right angle 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 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 should be redirected. So it can support users to save the running expense and increase the transmission effectiveness. The input flange dimensions of PAR right angle gearbox is open to be customized, consequently, it is compatible with any makes of the servo motors, stepper motors and brushless DC motors.
