Low backlash right angle servo worm reducer
high precision worm gear is an ideal replacement 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 travel systems
Worm shaft in series can be driven by one motor to accomplish synchronous outcome of multiple worm wheels. It’s been used in computerized 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 ideal flank of worm shaft using different lead angle,causing tooth thickness gradual modification,To be able to approach worm shaft and modify backlash.
Low backlash Features :
— Worm equipment gyration backlash could be adjusted to significantly less than 1 arc.

Low rotation Make choice :
The next headings contain information on essential components for selection and correct use of gearbox.
For particular data on the gearbox array,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 predicated on application requirement. It is suggested to be add up to or significantly less than torque Mn2 the gearbox under review is rated for.
Computational torque value to be utilized when choosing the gearbox. It is calculated considering the expected torque Mr2 and service issue fs, as per the relationship here after:
1、Rated input power
The parameter can be found 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 is the power transmitted at gearbox output. it is usually calculated with the following formulas:
Efficiency is a good parameter which has a major impact on the sizing of certain applications, and basically is determined by gear pair designelements.
The mesh info table on page 9 shows dynamic efficiency (n1=1400)and static efficiency values.
Understand that these values are just achieved following the unit features been run in and reaches the working temperature.
The dynamic efficiency is the relationship of power delivered at output shaft P2 to power applied at input shaft P1:
Efficiency obtained at start-up of the gearbox. Although this is generally not really significant aspect for helical gears, it can be instead critical when selecting worm gearmotors operating under intermittent duty.
SERVICE FACTOR [ fs ]
The service factor (fs ) depends upon the operating conditions the gearbox is put through the parameters that need to be taken into consideration to select the most enough servies factor correctly comprise:
1. type of load of the operated machine : A – B – C
2. length of daily functioning time: hours/day(△)
3. start-up regularity: starts/hour (*)
TYPE OF LOAD: A good – uniform, fa≤0.3
B – average shocks, fa≤3
C – major shocks, fa≤10
–Je(kgm2) minute of the exterior 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 elements, admirers, assembly lines, conveyor belts for light materials, tiny mixers, lifts, cleaning equipment, fillers, control machines.
