Low backlash right position servo worm reducer
high precision worm equipment is an ideal replacement for precision planetary gearbox,the equipment manufacturer can substantially reduce the expense of using precision planetary gearbox
The designer’s ideal solution is to rotate 90 degrees to set up the servo motor get systems
Worm shaft in series could be driven by 1 motor to attain synchronous end result of multiple worm tires. It’s been used in automatic polishing cellular phone shell and other equipments
Servo worm gear devices have three types : 45 – 50 – 55 – 63 – 75 – 90 ,with dual lead worm drive.Left and ideal flank of worm shaft using different lead angle,causing tooth thickness gradual change,So that you can approach worm shaft and change backlash.
Low backlash Features :
— Worm equipment gyration backlash can be adjusted to less than 1 arc.
— Reducer can be re-adjusted the gap after using .
— Input with coupling : reliable without backlash .
— Output using conical clamping band couplings : reliable without backlash.
Precision rotary motion
— Reducing the noise and vibration that’s caused by the strain change and the switch of cutting force.
— reducing the noise and impact that’s caused by the corotation and reverse.
— By lowering worm abrasion.
— Increasing worm output response acceleration .
Precision Indexing device
— CNC machine, assembly series, cutting machine, transmission lines, etc.
— Indexing device,accurate studying mechanism require accurate movement occasions .
Speed changing situations
— Reducing the noises and the impact that is due to speed change.
— Reducing the worm abrasion that is caused by speed changes.
Low rotation Make choice :
The following headings contain information on essential elements for selection and correct usage of gearbox.
For particular data on the gearbox collection,see the relevant chapters.
1、Rated output torque
The torque which can be transmitted continually through the output shaft, with the gear unit operated under a service factor fs = 1.
The torque demand predicated on application requirement. It is recommended to be add up to or less than torque Mn2 the gearbox under study is rated for.
Computational torque value to be utilized when choosing the gearbox. It really is calculated considering the required torque Mr2 and service element fs, as per the relationship here after:
1、Rated input power
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
This value may be the power transmitted at gearbox output. it could be calculated with the following formulas:
Efficiency is a good parameter that includes a major effect on the sizing of certain applications, and basically will depend 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 only achieved after the unit offers been run in and is at the working temperature.
The dynamic efficiency is 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 that is generally certainly not significant component for helical gears, it may 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 put through the parameters that require to be taken under consideration to choose the most enough 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 frequency: starts/hour (*)
TYPE OF LOAD: A good – uniform, fa≤0.3
B – moderate shocks, fa≤3
C – weighty shocks, fa≤10
–Je(kgm2) minute of the external inertia reduced at the get shaft
–Jm(kgm2) second of inertia of motor
–If fa>10 please contact our Technical Service

series has a 90 degree input via helical bevel equipment,and its large tapered roller bearings also help to make it ideal for large radial and axial forces. PAR right angle reducer features an exceptionally short, light yet rigid housing and full compatibility with standard electric motor adapters.PAR right angle planetary gearbox combines the benefits of a compact right position gearbox and the ones of a conventional planetary gearbox.Highest Accuracy, Highest Torque and Calm 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 should be redirected. So it can support users to save lots of the running cost and increase the transmission proficiency. The input flange dimensions of PAR proper angle gearbox is open to be customized, consequently, it is compatible with any makes of the servo motors, stepper motors and brushless DC motors.
