Low backlash right angle servo worm reducer
high precision worm gear is an ideal replacement for precision planetary gearbox,the equipment manufacturer may 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 travel systems
Worm shaft found in series can be driven by 1 motor to achieve synchronous output of multiple worm wheels. It has been used in programmed polishing cellular 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 ideal flank of worm shaft working with different lead angle,leading to tooth thickness gradual switch,To be able to maneuver worm shaft and adapt backlash.
Low backlash Features :
— Worm equipment gyration backlash could be adjusted to significantly less than 1 arc.
— Reducer can 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 noise and vibration that’s caused by the strain change and the change of cutting force.
— reducing the noises and impact that’s caused by the corotation and reverse.
— By reducing worm abrasion.
— Increasing worm output response swiftness .
Precision Indexing device
— CNC machine, assembly brand, cutting machine, transmission lines, etc.
— Indexing device,accurate studying mechanism require accurate activity 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 make use of gearbox.
For certain data on the gearbox range,start to see the relevant chapters.
OUTPUT TORQUE
1、Rated output torque
Mn2 [Nm]
The torque that can be transmitted consistently through the output shaft, with the gear 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 less than torque Mn2 the gearbox under study is rated for.
3、Calculated torque
Mc2 [Nm]
Computational torque value to be used when selecting the gearbox. It really is calculated considering the expected torque Mr2 and service element fs, as per the relationship 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 may be the power transmitted at gearbox output. it might be calculated with the following formulas:
EFFICIENCY
Efficiency is a good 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.
Understand that these values are just achieved after the unit features 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 ) is determined by the operating conditions the gearbox is subjected to the parameters that need to be taken under consideration to select the most sufficient servies factor correctly comprise:
1. type of load of the managed equipment : A – B – C
2. length of daily operating 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 – hefty shocks, fa≤10
fa=Je/Jm
–Je(kgm2) instant of the exterior inertia reduced at the drive shaft
–Jm(kgm2) instant of inertia of motor
–If fa>10 please contact our Technical Service

series has a 90 degree suggestions via helical bevel equipment,and its giant tapered roller bearings also try to make it ideal for large radial and axial forces. PAR right angle reducer features an extremely short, light yet rigid housing and full compatibility with standard motor adapters.PAR right position planetary gearbox combines the advantages of a compact right position gearbox and those of a typical planetary gearbox.Highest Precision, Highest Torque and Quiet 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 energy flow needs to be redirected. So that it can help users to save the running cost and enhance the transmission effectiveness. The input flange dimensions of PAR correct angle gearbox is open to be customized, consequently, it is compatible with any brands of the servo brushless DC motors, stepper motors and motors.
