Low backlash right angle servo worm reducer
high precision worm gear is an ideal substitute for precision planetary gearbox,the equipment manufacturer can substantially reduce the price of using precision planetary gearbox
The designer’s ideal solution is to rotate 90 degrees to set up the servo motor drive systems
Worm shaft found in series could be driven by one motor to accomplish 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.Still left and right flank of worm shaft using different lead angle,causing tooth thickness gradual change,To be able to move worm shaft and change backlash.
Low backlash Features :
— Worm equipment gyration backlash can 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 ring couplings : reliable without backlash.
Applications :
Precision rotary motion
— Reducing the sound and vibration that’s caused by the load change and the change of cutting force.
— reducing the sound and impact that’s caused by the corotation and reverse.
— By lowering worm abrasion.
— Increasing worm output response swiftness .
Precision Indexing device
— CNC machine, assembly brand, cutting machine, transmitting lines, etc.
— Indexing device,accurate reading mechanism require accurate movement occasions .
Speed changing situations
— Reducing the noise and the impact that is caused by speed change.
— Reducing the worm abrasion that is caused by speed changes.
Low rotation Make decision :
The following headings contain information on essential elements for selection and correct utilization of gearbox.
For specific data on the gearbox selection,see the relevant chapters.
OUTPUT TORQUE
1、Rated output torque
Mn2 [Nm]
The torque which can be transmitted continuously 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 recommended to be add up to or less than torque Mn2 the gearbox under study is rated for.
3、Calculated torque
Mc2 [Nm]
Computational torque value to be used when choosing the gearbox. It is calculated considering the required torque Mr2 and service factor 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 really is calculated with the following formulas:
EFFICIENCY
Efficiency is a good parameter which has a major effect 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.
Remember that these values are only achieved after the unit features been run found 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 not really significant aspect for helical gears, it can be instead critical when choosing worm gearmotors functioning under intermittent duty.
SERVICE FACTOR [ fs ]
The service factor (fs ) depends upon the operating conditions the gearbox is subjected to the parameters that require to be taken under consideration to choose the most enough servies factor correctly comprise:
1. type of load of the operated equipment : 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 – average shocks, fa≤3
C – weighty shocks, fa≤10
fa=Je/Jm
–Je(kgm2) moment of the external inertia reduced at the get shaft
–Jm(kgm2) second of inertia of motor
–If fa>10 please contact our Technical Service
