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 cost of using precision planetary gearbox
The designer’s ideal solution is to rotate 90 degrees to install the servo motor drive systems
Worm shaft in series could be driven by a single motor to achieve synchronous end result of multiple worm tires. It has been used in programmed polishing mobile phone shell and other equipments
Servo worm gear products have three types : 45 – 50 – 55 – 63 – 75 – 90 ,with dual lead worm drive.Left and right flank of worm shaft working with different lead angle,leading to tooth thickness gradual change,So that you can maneuver worm shaft and change backlash.
Low backlash Features :
— Worm equipment 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 using conical clamping ring couplings : reliable without backlash.
Applications :
Precision rotary motion
— Reducing the sound and vibration that’s caused by the strain change and the change of cutting force.
— reducing the noises and impact that is due to the corotation and reverse.
— By lowering worm abrasion.
— Increasing worm output response rate .
Precision Indexing device
— CNC machine, assembly brand, cutting machine, transmitting lines, etc.
— Indexing device,accurate browsing mechanism require accurate motion occasions .
Speed changing situations
— Reducing the noise and the impact that is caused by speed change.
— Lowering the worm abrasion that is due to speed changes.
Low rotation Make choice :
The next headings contain information on essential elements for selection and correct make use 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 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 significantly less than torque Mn2 the gearbox under research is rated for.
3、Calculated torque
Mc2 [Nm]
Computational torque value to be used when selecting the gearbox. It really is calculated considering the needed torque Mr2 and service aspect 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, 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 could be calculated with the next formulas:
EFFICIENCY
Efficiency is a parameter which has 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.
Remember that these values are only achieved following 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 in start-up of the gearbox. Although that is generally not significant factor for helical gears, it might be instead critical when choosing worm gearmotors functioning 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 select the most sufficient servies factor effectively comprise:
1. type of load of the operated equipment : A – B – C
2. length of daily working time: hours/day(△)
3. start-up rate of recurrence: starts/hour (*)
TYPE OF LOAD: A good – uniform, fa≤0.3
B – average shocks, fa≤3
C – serious shocks, fa≤10
fa=Je/Jm
–Je(kgm2) instant of the external inertia reduced at the travel shaft
–Jm(kgm2) point in time of inertia of motor
–If fa>10 please contact our Technical Service

series has a 90 degree type via helical bevel gear,and its large tapered roller bearings also try to make it ideal for large radial and axial forces. PAR right position reducer features an extremely short, light however rigid housing and total compatibility with standard engine adapters.PAR right position planetary gearbox combines the benefits of a compact right position gearbox and the ones 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 action control applications wherein the power flow must be redirected. So that it can help users to save lots of the running cost and enhance the transmission performance. The input flange dimensions of PAR right angle gearbox is open to be customized, therefore, it is compatible with any brands of the servo motors, stepper motors and brushless DC motors.
