Low backlash right angle servo worm reducer
high precision worm equipment is an ideal substitute for precision planetary gearbox,the gear manufacturer may substantially reduce the expense 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 could be driven by 1 motor to achieve synchronous result of multiple worm wheels. It has been used in automated polishing cellular phone shell and other equipments
Servo worm gear units have three types : 45 – 50 – 55 – 63 – 75 – 90 ,with dual lead worm drive.Still left and right flank of worm shaft using different lead angle,causing tooth thickness gradual switch,To be able to move worm shaft and adapt 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 .
— Input with coupling : reliable without backlash .
— Output using conical clamping band couplings : reliable without backlash.
Applications :
Precision rotary motion
— Reducing the noise and vibration that is caused by the strain change and the modification of cutting force.
— reducing the noise and impact that is due to the corotation and reverse.
— By lessening worm abrasion.
— Increasing worm output response rate .
Precision Indexing device

Low rotation Make choice :
The next headings contain information on essential components for selection and correct make use of gearbox.
For particular data on the gearbox array,start to see the relevant chapters.
OUTPUT TORQUE
1、Rated output torque
Mn2 [Nm]
The torque which can be transmitted consistently through the output shaft, with the gear unit operated under something factor fs = 1.
2、Required torque
Mr2 [Nm]
The torque demand predicated on application requirement. It is suggested to be add up to or less than torque Mn2 the gearbox under research is rated for.
3、Calculated torque
Mc2 [Nm]
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:
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, based on input speed n1 and service factor fs= 1.
2、Rated output power
Pn2 [kW]
This value is the power transmitted at gearbox output. it might be calculated with the next formulas:
EFFICIENCY
Efficiency is a parameter which has a major impact on the sizing of certain applications, and basically is determined by 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 offers been run in and reaches the working temperature.
1、Dynamic efficiency
[ηd]
The dynamic efficiency is 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 that is generally not really significant aspect for helical gears, it could be instead critical when choosing worm gearmotors working under intermittent duty.
SERVICE FACTOR [ fs ]
The service factor (fs ) will depend on the operating conditions the gearbox is put through the parameters that require to be taken under consideration to select the most sufficient servies factor effectively comprise:
1. kind of load of the operated equipment : A – B – C
2. length of daily operating time: hours/day(△)
3. start-up regularity: starts/hour (*)
TYPE OF LOAD: A – uniform, fa≤0.3
B – average shocks, fa≤3
C 
– serious shocks, fa≤10
fa=Je/Jm
–Je(kgm2) second of the external inertia reduced at the travel shaft
–Jm(kgm2) minute of inertia of motor
–If fa>10 please contact our Technical Service
