Low backlash right position servo worm reducer
high precision worm equipment is an ideal replacement for precision planetary gearbox,the gear 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 get systems
Worm shaft in series can be driven by a single motor to achieve synchronous productivity of multiple worm wheels. It’s been used in computerized polishing cellular phone shell and other equipments
Servo worm gear products have three types : 45 – 50 – 55 – 63 – 75 – 90 ,with dual business lead worm drive.Still left and best suited flank of worm shaft using different lead angle,leading to tooth thickness gradual change,So that you can move worm shaft and change backlash.
Low backlash Features :
— Worm equipment gyration backlash could 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 sound and vibration that is caused by the load change and the transformation of cutting force.
— reducing the noise and impact that is due to the corotation and reverse.
— By lowering worm abrasion.
— Increasing worm output response speed .
Precision Indexing device
— CNC machine, assembly brand, cutting machine, transmitting lines, etc.
— Indexing device,accurate browsing mechanism require accurate activity occasions .
Speed changing situations
— Reducing the noises and the impact that’s due to speed change.
— Lowering the worm abrasion that’s due to speed changes.
Low rotation Make decision :
The next headings contain information on essential factors for selection and correct make use of gearbox.
For specific data on the gearbox assortment,see the relevant chapters.
1、Rated output torque
The torque that can be transmitted continuously through the output shaft, with the apparatus unit operated under a service factor fs = 1.
The torque demand based on application requirement. It is suggested to be equal to or less than torque Mn2 the gearbox under analysis is rated for.
Computational torque value to be utilized when choosing the gearbox. It is calculated considering the expected torque Mr2 and service aspect fs, as per the partnership here after:
1、Rated input power
The parameter are available in the gearbox rating charts and represents the KW which 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 usually is calculated with the following formulas:
Efficiency is a good parameter that includes a major affect on the sizing of certain applications, and basically depends on gear pair designelements.
The mesh data table on page 9 shows dynamic efficiency (n1=1400)and static efficiency values.
Understand that these values are just achieved after the unit offers been run in and reaches the working temperature.
The dynamic efficiency may be 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 really significant issue for helical gears, it can be instead critical when choosing worm gearmotors working under intermittent duty.
SERVICE FACTOR [ fs ]
The service factor (fs ) will depend on the operating conditions the gearbox is put through the parameters that need to be taken under consideration to choose the most sufficient servies factor correctly 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 good – uniform, fa≤0.3
B – moderate shocks, fa≤3
C – hefty shocks, fa≤10
–Je(kgm2) point in time of the exterior inertia reduced at the drive shaft
–Jm(kgm2) instant of inertia of motor
–If fa>10 please contact our Technical Service

series has a 90 degree source via helical bevel gear,and its giant tapered roller bearings also make it ideal for great radial and axial forces. PAR right angle reducer features an extremely short, light yet rigid housing and complete compatibility with standard engine adapters.PAR right position planetary gearbox combines the advantages of a compact right position gearbox and the ones of a typical planetary gearbox.Highest Accuracy, 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 action control applications wherein the energy flow has to be redirected. So it can help users to save lots of the running expense and improve the transmission productivity. The input flange measurements of PAR proper angle gearbox is open to be customized, as a result, it is appropriate for any makes of the servo stepper motors, brushless DC motors and motors.
