Low backlash right position servo worm reducer
high precision worm gear is an ideal replacement for precision planetary gearbox,the equipment manufacturer can substantially reduce the cost of using precision planetary gearbox
The designer’s ideal solution is to rotate 90 degrees to install the servo motor travel systems
Worm shaft found in series can be driven by one motor to achieve synchronous outcome of multiple worm wheels. It’s been used in automatic polishing cellular phone shell and other equipments
Servo worm gear systems have three types : 45 – 50 – 55 – 63 – 75 – 90 ,with dual lead worm drive.Left and ideal 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 could be re-adjusted the gap after using .

The next headings contain information on essential factors for selection and correct utilization of gearbox.
For certain data on the gearbox array,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 based on application requirement. It is suggested to be equal to or significantly less than torque Mn2 the gearbox under research is rated for.
3、Calculated torque
Mc2 [Nm]
Computational torque value to be used when selecting the gearbox. It really is calculated considering the needed torque Mr2 and service point fs, as per the relationship here after:
POWER
1、Rated input power
Pn1 [kW]
The parameter can be found 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 could be calculated with the next formulas:
EFFICIENCY
Efficiency is a good parameter which has a major effect 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 only 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 in start-up of the gearbox. Although this is generally certainly not significant issue for helical gears, it may 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 require to be taken under consideration to select the most satisfactory servies factor effectively comprise:
1. type of load of the managed machine : A – B – C
2. length of daily operating 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 – major shocks, fa≤10
fa=Je/Jm
–Je(kgm2) minute of the external inertia reduced at the travel shaft
–Jm(kgm2) second of inertia of motor
–If fa>10 please contact our Technical Service
