Low backlash right angle servo worm reducer
high precision worm equipment is an ideal replacement for precision planetary gearbox,the equipment manufacturer can substantially reduce the price tag on 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 accomplish synchronous output of multiple worm tires. It has been used in computerized polishing cellular phone shell and other equipments
Servo worm gear models have three types : 45 – 50 – 55 – 63 – 75 – 90 ,with dual business lead worm drive.Left and best suited flank of worm shaft using different lead angle,causing tooth thickness gradual modification,So that you can maneuver worm shaft and change backlash.
Low backlash Features :
— Worm gear gyration backlash could be adjusted to significantly less than 1 arc.
— Reducer can be re-adjusted the gap after using .

Low rotation Make choice :
The next headings contain information on essential elements for selection and correct utilization of gearbox.
For particular data on the gearbox selection,start to see the relevant chapters.
1、Rated output torque
The torque that can be transmitted consistently through the output shaft, with the apparatus unit operated under a service factor fs = 1.
The torque demand based 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 selecting the gearbox. It 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 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 might be calculated with the next formulas:
Efficiency is a parameter that includes a major influence on the sizing of certain applications, and basically depends upon gear pair designelements.
The mesh data table on page 9 shows dynamic efficiency (n1=1400)and static efficiency values.
Understand that these values are only achieved following the unit offers 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 really significant issue for helical gears, it could be instead critical when choosing worm gearmotors working under intermittent duty.
SERVICE FACTOR [ fs ]
The service factor (fs ) depends on the operating conditions the gearbox is put through the parameters that require to be taken into consideration to choose the most satisfactory servies factor correctly comprise:
1. kind 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 good – uniform, fa≤0.3
B – moderate shocks, fa≤3
C – large shocks, fa≤10
–Je(kgm2) second 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 includes a 90 degree input via helical bevel equipment,and its large tapered roller bearings also try to make it ideal for high radial and axial forces. PAR right position reducer features an exceptionally short, light however rigid housing and complete compatibility with standard engine adapters.PAR right position planetary gearbox combines the benefits of a compact right angle gearbox and the ones of a typical planetary gearbox.Highest Precision, Highest Torque and Quiet Operation are provided 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 it can help users to save lots of the running cost and increase the transmission efficiency. The input flange measurements of PAR proper angle gearbox is available to be customized, as a result, it is compatible with any makes of the servo brushless DC motors, stepper motors and motors.
