Low backlash right angle servo worm reducer

Low backlash right angle servo worm reducer
high precision worm gear 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 drive systems

Worm shaft in series can be driven by a single motor to attain synchronous productivity of multiple worm tires. It has been used in computerized polishing mobile phone shell and other equipments
Servo worm gear units have three types : 45 – 50 – 55 – 63 – 75 – 90 ,with dual lead worm drive.Left and best flank of worm shaft using different lead angle,leading to tooth thickness gradual switch,So that you can move worm shaft and change backlash.

Low backlash Features :

— Worm gear gyration backlash can 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 ring couplings : reliable without backlash.

Applications :

Precision rotary motion

— Reducing the noises and vibration that’s caused by the load change and the modification of cutting force.
— reducing the noises and impact that is due to the corotation and reverse.
— By reducing worm abrasion.
— Increasing worm output response quickness .

Precision Indexing device

— CNC machine, assembly brand, cutting machine, transmission lines, etc.
— Indexing device,accurate reading mechanism require accurate movement occasions .

Speed changing situations

— Reducing the noise and the impact that is caused by speed change.
— Lessening the worm abrasion that is due to speed changes.
Low rotation Make decision :

The next headings contain information on essential factors for selection and correct use of gearbox.
For specific data on the gearbox assortment,start to see the relevant chapters.
OUTPUT TORQUE
1、Rated output torque
Mn2 [Nm]
The torque which can be transmitted continuously through the output shaft, with the gear 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 less than torque Mn2 the gearbox under analysis is rated for.
3、Calculated torque
Mc2 [Nm]
Computational torque value to be utilized when selecting the gearbox. It is calculated considering the needed torque Mr2 and service aspect 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, based on input speed n1 and service factor fs= 1.
2、Rated output power
Pn2 [kW]
This value may be the power transmitted at gearbox output. it can be calculated with the following formulas:
EFFICIENCY
Efficiency is a parameter which has a major effect 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.
Remember that these values are just achieved following the unit offers been run in and reaches 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 element for helical gears, it could be instead critical when selecting worm gearmotors operating under intermittent duty.
SERVICE FACTOR [ fs ]
The service factor (fs ) will depend on the operating conditions the gearbox is put through the parameters that require to be taken under consideration to select the most sufficient servies factor correctly comprise:
1. type of load of the managed machine : A – B – C
2. length of daily working time: hours/day(△)
3. start-up rate of recurrence: starts/hour (*)
TYPE OF LOAD: A good – uniform, fa≤0.3
B – average shocks, fa≤3
C – heavy shocks, fa≤10
fa=Je/Jm
–Je(kgm2) second 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 supplies, supporters, assembly lines, conveyor belts for light materials, small mixers, lifts, cleaning equipment, fillers, control machines.
B -Winding units, woodworking machine feeders, items lifts, balancers,threading devices, channel mixers, conveyor belts for major materials,winches, sliding doorways, fertilizer scrapers, packing equipment, concrete mixers, crane mechanisms, milling cutters, folding machines, gear pumps.
C -Mixers for heavy materials, shears, presses, centrifuges, rotating helps, winches and lifts for serious materials, grinding lathes, natural stone mills, bucket elevators, drilling equipment, hammer mills, cam presses, folding equipment, turntables, tumbling barrels, vibrators, shredders.
series has a 90 degree suggestions via helical bevel equipment,and its large tapered roller bearings also produce it ideal for large radial and axial forces. PAR right position reducer features an exceptionally short, light but rigid housing and total compatibility with standard 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 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 motion control applications wherein the energy flow has to be redirected. So that it can help users to save the running expense and improve the transmission effectiveness. The input flange measurements of PAR right angle gearbox is open to be customized, consequently, it is appropriate for any brands of the servo stepper motors, brushless DC motors and motors.
