Low backlash right angle servo worm reducer
high precision worm gear is an ideal substitute for precision planetary gearbox,the gear manufacturer may 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 outcome of multiple worm tires. It has been used in automated polishing mobile phone shell and other equipments
Servo worm gear systems 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,leading to 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.
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 is 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 movements 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 use of gearbox.
For certain data on the gearbox assortment,start to see the relevant chapters.
1、Rated output torque
The torque that can be transmitted consistently through the output shaft, with the gear unit operated under something factor fs = 1.
The torque demand based on application requirement. It is recommended to be equal to or significantly less than torque Mn2 the gearbox under review is rated for.
Computational torque value to be utilized when selecting the gearbox. It is calculated considering the needed torque Mr2 and service issue fs, as per the partnership here after:
1、Rated input power
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
This value is the power transmitted at gearbox output. it is usually calculated with the following formulas:
Efficiency is a parameter that includes a major influence on the sizing of certain applications, and basically depends on 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 following the unit features been run in and reaches the working temperature.
The dynamic efficiency may be the relationship of power delivered at output shaft P2 to power applied at input shaft P1:
Efficiency obtained in start-up of the gearbox. Although this 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 upon the operating conditions the gearbox is put through the parameters that require to be taken into consideration to choose the most satisfactory servies factor properly 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 – hefty shocks, fa≤10
–Je(kgm2) moment of the exterior inertia reduced at the drive 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 major tapered roller bearings also try to make it ideal for superior radial and axial forces. PAR right position reducer features an extremely short, light however rigid housing and complete compatibility with standard engine adapters.PAR right angle planetary gearbox combines the features of a compact right angle 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 movement control applications wherein the power flow must be redirected. So that it can help users to save lots of the running price and improve the transmission effectiveness. The input flange measurements of PAR right angle gearbox is available to be customized, so, it is appropriate for any brands of the servo stepper motors, motors and brushless DC motors.
