Low backlash right position servo worm reducer
high precision worm gear is an ideal substitute 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 set up the servo motor drive systems
Worm shaft in series could be driven by a single motor to attain synchronous end result of multiple worm wheels. It has been used in automatic polishing mobile phone shell and other equipments
Servo worm gear products have three types : 45 – 50 – 55 – 63 – 75 – 90 ,with dual lead worm drive.Left and ideal flank of worm shaft working with different lead angle,leading to tooth thickness gradual change,To be able to approach worm shaft and adapt backlash.
Low backlash Features :
— Worm equipment gyration backlash could be adjusted to 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.
Applications :
Precision rotary motion
— Reducing the noises and vibration that is caused by the load change and the transformation of cutting force.
— reducing the noises and impact that’s due to the corotation and reverse.
— By reducing worm abrasion.
— Increasing worm output response velocity .
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 caused by speed change.
— Lowering the worm abrasion that’s caused by speed changes.
Low rotation Make choice :
The following headings contain information on essential factors for selection and correct make use of gearbox.
For certain data on the gearbox array,see the relevant chapters.
OUTPUT TORQUE
1、Rated output torque
Mn2 [Nm]
The torque that can be transmitted constantly through the output shaft, with the apparatus unit operated under something factor fs = 1.
2、Required torque
Mr2 [Nm]
The torque demand predicated on application requirement. It is recommended to be add up to or significantly less than torque Mn2 the gearbox under analysis is rated for.
3、Calculated torque
Mc2 [Nm]
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 partnership here after:
POWER
1、Rated input power
Pn1 [kW]
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
Pn2 [kW]
This value is the power transmitted at gearbox output. it usually is calculated with the following formulas:
EFFICIENCY
Efficiency is a good parameter which has a major effect on the sizing of certain applications, and basically is determined by gear pair designelements.
The mesh info table on page 9 shows dynamic efficiency (n1=1400)and static efficiency values.
Remember that these values are just achieved after the unit features been run in and is at the working temperature.
1、Dynamic efficiency
[ηd]
The dynamic efficiency is the relationship of power delivered at output shaft P2 to power applied at input shaft P1:
2、Static efficiency
[ηs]
Efficiency obtained at start-up of the gearbox. Although that is generally certainly not significant factor for helical gears, it may be instead critical when selecting worm gearmotors functioning under intermittent duty.
SERVICE FACTOR [ fs ]
The service factor (fs ) will depend on the operating conditions the gearbox is subjected to the parameters that need to be taken under consideration to choose the most sufficient servies factor appropriately comprise:
1. type of load of the managed equipment : A – B – C
2. length of daily functioning time: hours/day(△)
3. start-up regularity: starts/hour (*)
TYPE OF LOAD: A good – uniform, fa≤0.3
B – average shocks, fa≤3
C – serious shocks, fa≤10
fa=Je/Jm
–Je(kgm2) point in time of the external inertia reduced at the get shaft
–Jm(kgm2) minute of inertia of motor
–If fa>10 please contact our Technical Service
A -Screw feeders for light resources, admirers, assembly 
lines, conveyor belts for light materials, tiny mixers, lifts, cleaning machines, fillers, control machines.
B -Winding equipment, woodworking machine feeders, products lifts, balancers,threading machines, channel mixers, conveyor belts for major materials,winches, sliding doors, fertilizer scrapers, packing equipment, cement mixers, crane mechanisms, milling cutters, folding machines, gear pumps.
C -Mixers for heavy components, shears, presses, centrifuges, rotating works with, winches and lifts for major materials, grinding lathes, rock mills, bucket elevators, drilling devices, hammer mills, cam presses, folding machines, turntables, tumbling barrels, vibrators, shredders.
series has a 90 degree suggestions via helical bevel gear,and its good sized tapered roller bearings also make it ideal for great radial and axial forces. PAR right position reducer features an extremely short, light but rigid housing and total compatibility with standard electric motor adapters.PAR right angle planetary gearbox combines the advantages of a compact right angle gearbox and those of a conventional planetary gearbox.Highest Precision, Highest Torque and Quiet 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 energy flow must be redirected. So it can support users to save the running expense and improve the transmission performance. The input flange dimensions of PAR right angle gearbox is open to be customized, subsequently, it is appropriate for any brands of the servo motors, stepper motors and brushless DC motors.
