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 set up 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’s been used in computerized polishing cellular phone shell and other equipments
Servo worm gear systems have three types : 45 – 50 – 55 – 63 – 75 – 90 ,with dual lead worm drive.Still left and ideal flank of worm shaft using different lead angle,leading to tooth thickness gradual transformation,So that you can approach worm shaft and adapt backlash.
Low backlash Features :
— Worm gear gyration backlash can 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.
Precision rotary motion
— Reducing the noise and vibration that is caused by the load change and the transformation of cutting force.
— reducing the sound and impact that’s caused by the corotation and reverse.
— By cutting down worm abrasion.
— Increasing worm output response velocity .
Precision Indexing device
— CNC machine, assembly series, cutting machine, transmitting lines, etc.
— Indexing device,accurate browsing 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 next headings contain information on essential elements for selection and correct use of gearbox.
For specific data on the gearbox collection,start to see the relevant chapters.
1、Rated output torque
The torque which can be transmitted constantly through the output shaft, with the gear unit operated under a service factor fs = 1.
The torque demand based on application requirement. It is suggested 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 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 may be the power transmitted at gearbox output. it can be calculated with the next formulas:
Efficiency is a parameter that includes a major impact on the sizing of certain applications, and basically is determined by 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 has been run in and reaches 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 at start-up of the gearbox. Although this is generally not significant issue for helical gears, it can be instead critical when selecting worm gearmotors working under intermittent duty.
SERVICE FACTOR [ fs ]
The service factor (fs ) will depend on the operating conditions the gearbox is subjected to the parameters that require to be taken into consideration to choose the most adequate servies factor properly comprise:
1. type of load of the operated equipment : A – B – C
2. length of daily operating time: hours/day(△)
3. start-up frequency: starts/hour (*)
TYPE OF LOAD: A good – uniform, fa≤0.3
B – moderate shocks, fa≤3
C – hefty shocks, fa≤10
–Je(kgm2) minute of the exterior inertia reduced at the get shaft
–Jm(kgm2) moment of inertia of motor
–If fa>10 please contact our Technical Service

series has a 90 degree type via helical bevel gear,and its giant tapered roller bearings also help to make it ideal for large radial and axial forces. PAR right angle reducer features an extremely short, light however rigid housing and full compatibility with standard electric motor adapters.PAR right position planetary gearbox combines the benefits of a compact right angle gearbox and the ones of a conventional planetary gearbox.Highest Precision, 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 movement control applications wherein the power flow needs to be redirected. So that it can help users to save lots of the running cost and improve the transmission proficiency. The input flange dimensions of PAR right angle gearbox is available to be customized, so, it is compatible with any brands of the servo motors, brushless DC motors and stepper motors.
