Low backlash right position servo worm reducer
high precision worm gear is an ideal replacement for precision planetary gearbox,the equipment manufacturer may substantially reduce the price 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 output of multiple worm wheels. It’s been used in programmed polishing mobile phone shell and other equipments
Servo worm gear models have three types : 45 – 50 – 55 – 63 – 75 – 90 ,with dual business lead worm drive.Left and ideal flank of worm shaft using different lead angle,causing tooth thickness gradual transformation,So that you can move worm shaft and adjust backlash.
Low backlash Features :
— Worm gear 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 band couplings : reliable without backlash.
Precision rotary motion
— Reducing the sound 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 velocity .
Precision Indexing device
— CNC machine, assembly brand, cutting machine, transmitting lines, etc.
— Indexing device,accurate studying mechanism require accurate activity occasions .
Speed changing situations
— Reducing the noises and the impact that is caused by speed change.
— Lessening the worm abrasion that is due to speed changes.
Low rotation Make decision :
The following headings contain information on essential elements for selection and correct usage of gearbox.
For specific data on the gearbox collection,see the relevant chapters.
1、Rated output torque
The torque which can be transmitted consistently through the output shaft, with the gear unit operated under something factor fs = 1.
The torque demand based on application requirement. It is suggested to be equal to or significantly less than torque Mn2 the gearbox under research is rated for.
Computational torque value to be used when selecting the gearbox. It is calculated considering the needed torque Mr2 and service component 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, 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 can be calculated with the next formulas:
Efficiency is a 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 just achieved after the unit has 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 this is generally not significant aspect for helical gears, it can be instead critical when choosing worm gearmotors operating under intermittent duty.
SERVICE FACTOR [ fs ]
The service factor (fs ) depends on the operating conditions the gearbox is subjected to the parameters that require to be taken into consideration to select the most enough servies factor appropriately comprise:
1. type of load of the operated machine : A – B – C
2. length of daily operating time: hours/day(△)
3. start-up frequency: starts/hour (*)
TYPE OF LOAD: A – uniform, fa≤0.3
B – average shocks, fa≤3
C – weighty shocks, fa≤10
–Je(kgm2) moment of the exterior 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 type via helical bevel equipment,and its giant tapered roller bearings also help to make it ideal for superior radial and axial forces. PAR right position reducer features an exceptionally short, light however rigid housing and complete compatibility with standard electric motor adapters.PAR right angle planetary gearbox combines the features of a compact right position gearbox and those of a conventional 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 power flow should be redirected. So it can help users to save the running price and enhance the transmission effectiveness. The input flange measurements of PAR correct angle gearbox is open to be customized, so, it is appropriate for any brands of the servo brushless DC motors, stepper motors and motors.
