Low backlash right angle servo worm reducer
high precision worm gear is an ideal replacement for precision planetary gearbox,the gear manufacturer can substantially reduce the cost 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 in series can be driven by one motor to attain synchronous output of multiple worm wheels. It’s been used in automatic polishing cellular phone shell and other equipments
Servo worm gear products have three types : 45 – 50 – 55 – 63 – 75 – 90 ,with dual business lead worm drive.Left and best flank of worm shaft working with different lead angle,leading to tooth thickness gradual change,So that you can approach worm shaft and change backlash.
Low backlash Features :
— Worm equipment gyration backlash could be adjusted to 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 noises and vibration that’s caused by the load change and the change 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 speed .
Precision Indexing device
— CNC machine, assembly collection, cutting machine, transmission lines, etc.
— Indexing device,accurate reading mechanism require accurate motion occasions .
Speed changing situations
— Reducing the noise and the impact that is due to speed change.
— Lowering the worm abrasion that’s caused by speed changes.
Low rotation Make decision :
The following headings contain information on essential factors 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 that can be transmitted continually through the output shaft, with the apparatus unit operated under a service factor fs = 1.
2、Required torque
Mr2 [Nm]
The torque demand based on application requirement. It is recommended to be add up to or significantly less than torque Mn2 the gearbox under analysis is rated for.
3、Calculated torque
Mc2 [Nm]
Computational torque value to be used when selecting the gearbox. It is calculated considering the required torque Mr2 and service component fs, as per the partnership here after:
POWER
1、Rated input power
Pn1 [kW]
The parameter are available in the gearbox rating charts and represents the KW that can be safely transmitted to the gearbox, based 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 can be calculated with the following formulas:
EFFICIENCY
Efficiency is a good parameter that includes a major influence on the sizing of certain applications, and basically depends upon gear pair designelements.
The mesh info table on page 9 shows dynamic efficiency (n1=1400)and static efficiency values.
Understand that these values are only achieved after the unit has 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 in start-up of the gearbox. Although that is generally not significant point for helical gears, it might 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 subjected to the parameters that need to be taken into consideration to choose the most satisfactory servies factor properly comprise:
1. kind 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 good – uniform, fa≤0.3
B – moderate shocks, fa≤3
C – large shocks, fa≤10
fa=Je/Jm
–Je(kgm2) moment of the external inertia reduced at the get shaft
–Jm(kgm2) instant of inertia of motor
–If fa>10 please contact our Technical Service

series includes a 90 degree suggestions via helical bevel gear,and its good sized tapered roller bearings also help to make it ideal for large radial and axial forces. PAR right angle reducer features an extremely short, light yet rigid housing and total compatibility with standard motor adapters.PAR right position planetary gearbox combines the advantages of a compact right angle gearbox and those of a conventional planetary gearbox.Highest Accuracy, Highest Torque and Quiet Operation are given 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 energy flow must be redirected. So that it can help users to save the running price and increase the transmission performance. The input flange sizes of PAR right angle gearbox is open to be customized, as a result, it is appropriate for any brands of the servo stepper motors, motors and brushless DC motors.
