Low backlash right position servo worm reducer
high precision worm gear is an ideal replacement for precision planetary gearbox,the gear manufacturer may substantially reduce the price tag on using precision planetary gearbox
The designer’s ideal solution is to rotate 90 degrees to set up the servo motor travel systems
Worm shaft found in series can be driven by 1 motor to attain synchronous outcome of multiple worm wheels. It has been used in automated polishing mobile phone shell and other equipments
Servo worm gear models have three types : 45 – 50 – 55 – 63 – 75 – 90 ,with dual lead worm drive.Left and best suited flank of worm shaft using different lead angle,leading to tooth thickness gradual transformation,To enable you to move worm shaft and adjust backlash.
Low backlash Features :
— Worm gear gyration backlash can be adjusted to significantly less than 1 arc.
— Reducer could be re-adjusted the gap after using .
— Input with coupling : reliable without backlash .
— Output working with conical clamping ring couplings : reliable without backlash.

The following headings contain information on essential elements for selection and correct use of gearbox.
For particular data on the gearbox collection,start to 
see the relevant chapters.
OUTPUT TORQUE
1、Rated output torque
Mn2 [Nm]
The torque that can be transmitted consistently through the output shaft, with the apparatus unit operated under something factor fs = 1.
2、Required torque
Mr2 [Nm]
The torque demand predicated on application requirement. It is recommended to be equal to or significantly less than torque Mn2 the gearbox under review is rated for.
3、Calculated torque
Mc2 [Nm]
Computational torque value to be utilized when selecting the gearbox. It is calculated considering the expected torque Mr2 and service issue fs, as per the relationship here after:
POWER
1、Rated input power
Pn1 [kW]
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
Pn2 [kW]
This value may be the power transmitted at gearbox output. it might be calculated with the next formulas:
EFFICIENCY
Efficiency is a good parameter that includes a major effect on the sizing of certain applications, and basically depends on gear pair designelements.
The mesh data table on page 9 shows dynamic efficiency (n1=1400)and static efficiency values.
Remember that these values are just achieved after the unit has been run in and reaches the working temperature.
1、Dynamic efficiency
[ηd]
The dynamic efficiency may be the relationship of power delivered at output shaft P2 to power applied at input shaft P1:
2、Static efficiency
[ηs]
Efficiency obtained at start-up of the gearbox. Although that is generally not significant factor for helical gears, it can be instead critical when selecting worm gearmotors working under intermittent duty.
SERVICE FACTOR [ fs ]
The service factor (fs ) is determined by the operating conditions the gearbox is subjected to the parameters that require to be taken under consideration to choose the most sufficient servies factor appropriately comprise:
1. type of load of the operated equipment : A – B – C
2. length of daily functioning time: hours/day(△)
3. start-up frequency: starts/hour (*)
TYPE OF LOAD: A good – uniform, fa≤0.3
B – average shocks, fa≤3
C – hefty shocks, fa≤10
fa=Je/Jm
–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
A good -Screw feeders for light supplies, admirers, assembly lines, conveyor belts for light materials, little mixers, lifts, cleaning equipment, fillers, control machines.
