Low backlash right angle servo worm reducer
high precision worm equipment is an ideal substitute for precision planetary gearbox,the equipment manufacturer may substantially reduce the price tag on 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 can be driven by a single motor to achieve synchronous outcome of multiple worm tires. It has been used in automated polishing mobile phone shell and other equipments
Servo worm gear products have three types : 45 – 50 – 55 – 63 – 75 – 90 ,with dual business lead worm drive.Still left and best flank of worm shaft working with different lead angle,causing tooth thickness gradual switch,To be able to move worm shaft and modify backlash.
Low backlash Features :
— Worm gear gyration backlash could be adjusted to significantly less than 1 arc.
— Reducer could be re-adjusted the gap after using .
— Input with coupling : reliable without backlash .
— Output working with conical clamping ring couplings : reliable without backlash.
Applications :
Precision rotary motion
— Reducing the sound and vibration that is caused by the strain change and the transformation of cutting force.
— reducing the sound and impact that’s due to the corotation and reverse.
— By cutting down worm abrasion.
— Increasing worm output response quickness .
Precision Indexing device
— CNC machine, assembly line, cutting machine, transmitting lines, etc.
— Indexing device,accurate browsing mechanism require accurate motion occasions .
Speed changing situations
— Reducing the noise and the impact that’s caused by speed change.
— Lowering the worm abrasion that’s caused by speed changes.
Low rotation Make decision :
The following headings contain information on essential components for selection and correct make use of gearbox.
For certain data on the gearbox assortment,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 based on application requirement. It is recommended to be equal to or less than torque Mn2 the gearbox under review 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 component 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 parameter that includes a major affect on the sizing of certain applications, and basically depends on gear pair designelements.
The mesh info table on page 9 shows dynamic efficiency (n1=1400)and static efficiency values.
Remember that these values are just achieved following the unit features 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 that is generally not significant point for helical gears, it might be instead critical when choosing worm gearmotors working under intermittent duty.
SERVICE FACTOR [ fs ]
The service factor (fs ) depends on the operating conditions the gearbox is put through the parameters that require to be taken into consideration to choose the most satisfactory servies factor correctly comprise:
1. type of load of the managed machine : A – B – C
2. length of daily functioning time: hours/day(△)
3. start-up rate of recurrence: starts/hour (*)
TYPE OF LOAD: A – uniform, fa≤0.3
B – average shocks, fa≤3
C – large shocks, fa≤10
fa=Je/Jm
–Je(kgm2) moment of the exterior inertia reduced at the get shaft
–Jm(kgm2) minute of inertia of motor
–If fa>10 please contact our Technical Service

series has a 90 degree suggestions via helical bevel gear,and its good sized tapered roller bearings also produce it ideal for great radial and axial forces. PAR right position reducer features an extremely short, light yet rigid housing and full compatibility with standard motor adapters.PAR right angle planetary gearbox combines the features of a compact right position gearbox and those of a typical planetary gearbox.Highest Accuracy, Highest Torque and Calm Operation are provided by 100% optimized Helical Gearing.
With the compact structure but powerful design, PAR right angle planetary gearbox is ideal option for motion control applications wherein the power flow needs to be redirected. So that it can support users to save lots of the running price and improve the transmission effectiveness. The input flange sizes of PAR right angle gearbox is available to be customized, so, it is compatible with any brands of the servo stepper motors, motors and brushless DC motors.
