Low backlash right angle servo worm reducer
high precision worm gear is an ideal substitute for precision planetary gearbox,the gear manufacturer can substantially reduce the price tag on using precision planetary gearbox

The designer’s ideal solution is to rotate 90 degrees to install the servo motor drive systems

Worm shaft found in series can be driven by a single motor to achieve synchronous end result of multiple worm wheels. It has been used in automatic polishing cellular phone shell and other equipments
Servo worm gear devices have three types : 45 – 50 – 55 – 63 – 75 – 90 ,with dual business lead worm drive.Left and best suited flank of worm shaft working with different lead angle,leading to tooth thickness gradual change,So that you can maneuver worm shaft and adapt backlash.

Low backlash Features :

— Worm equipment gyration backlash can be adjusted to less than 1 arc.
— Reducer can be re-adjusted the gap after using .
— Input with coupling : reliable without backlash .
— Output working with conical clamping band couplings : reliable without backlash.

Applications :

Precision rotary motion

— Reducing the sound and vibration that’s caused by the load change and the transformation of cutting force.
— reducing the noises and impact that is due to the corotation and reverse.
— By cutting down worm abrasion.
— Increasing worm output response acceleration .

Precision Indexing device

— CNC machine, assembly series, cutting machine, transmission lines, etc.
— Indexing device,accurate reading mechanism require accurate motion occasions .

Speed changing situations

— Reducing the noises and the impact that is caused by speed change.
— Lowering the worm abrasion that’s due to speed changes.
Low rotation Make choice :

The next headings contain information on essential elements for selection and correct use of gearbox.
For certain data on the gearbox collection,see the relevant chapters.
OUTPUT TORQUE
1、Rated output torque
Mn2 [Nm]
The torque which can be transmitted constantly 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 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 utilized when selecting the gearbox. It is calculated considering the needed torque Mr2 and service element fs, as per the partnership here after:
POWER
1、Rated input power
Pn1 [kW]
The parameter can be found in the gearbox rating charts and represents the KW that 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 is the power transmitted at gearbox output. it is usually calculated with the following formulas:
EFFICIENCY
Efficiency is a good parameter that includes a major influence 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 just achieved after the unit offers been run found in and is at 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 really significant point for helical gears, it may be instead critical when choosing worm gearmotors operating under intermittent duty.
SERVICE FACTOR [ fs ]
The service factor (fs ) depends on the operating conditions the gearbox is subjected to the parameters that need to be taken under consideration to choose the most satisfactory servies factor effectively comprise:
1. kind 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 – moderate shocks, fa≤3
C – serious shocks, fa≤10
fa=Je/Jm
–Je(kgm2) point in time 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 supplies, fans, assembly lines, conveyor belts for light materials, tiny mixers, lifts, cleaning equipment, fillers, control machines.
