Low backlash right angle servo worm reducer
high precision worm gear is an ideal substitute for precision planetary gearbox,the equipment manufacturer can substantially reduce the cost of using precision planetary gearbox
The designer’s ideal solution is to rotate 90 degrees to install the servo motor travel systems
Worm shaft in series could be driven by a single motor to achieve synchronous result of multiple worm wheels. 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 business lead worm drive.Left and ideal flank of worm shaft working with different lead angle,leading to tooth thickness gradual modification,So that you can move worm shaft and adjust backlash.
Low backlash Features :
— Worm gear gyration backlash can be adjusted to significantly 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 is caused by the load change and the change of cutting force.
— reducing the noise and impact that is due to the corotation and reverse.
— By reducing worm abrasion.
— Increasing worm output response acceleration .
Precision Indexing device
— CNC machine, assembly series, cutting machine, transmission lines, etc.
— Indexing device,accurate reading mechanism require accurate motion occasions .
Speed changing situations
— Reducing the noise and the impact that is caused by speed change.
— Cutting down the worm abrasion that is caused by speed changes.
Low rotation Make decision :
The next headings contain information on essential components for selection and correct usage of gearbox.
For certain data on the gearbox collection,start to see the relevant chapters.
1、Rated output torque
The torque that can be transmitted consistently through the output shaft, with the gear unit operated under a service factor fs = 1.
The torque demand based on application requirement. It is recommended to be equal to or less than torque Mn2 the gearbox under research is rated for.
Computational torque value to be utilized when selecting the gearbox. It really is calculated considering the expected 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 really is calculated with the following formulas:
Efficiency is a parameter that includes a major affect 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 following 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 this is generally not significant element for helical gears, it can be instead critical when selecting worm gearmotors operating under intermittent duty.
SERVICE FACTOR [ fs ]
The service factor (fs ) depends upon the operating conditions the gearbox is subjected to the parameters that require to be taken into consideration to choose the most sufficient servies factor effectively comprise:
1. kind of load of the managed machine : A – B – C
2. length of daily functioning time: hours/day(△)
3. start-up rate of recurrence: starts/hour (*)
TYPE OF LOAD: A – uniform, fa≤0.3
B – average shocks, fa≤3
C – major shocks, fa≤10
–Je(kgm2) second of the exterior inertia reduced at the drive shaft

series has a 90 degree type via helical bevel gear,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 complete compatibility with standard electric motor adapters.PAR right angle planetary gearbox combines the advantages of a compact right angle gearbox and the ones of a typical 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 movement control applications wherein the power flow has to be redirected. So it can help users to save the running expense and increase the transmission proficiency. The input flange sizes of PAR right angle gearbox is available to be customized, consequently, it is appropriate for any makes of the servo brushless DC motors, stepper motors and motors.
