Low backlash right angle servo worm reducer

Low backlash right position servo worm reducer
high precision worm gear is an ideal replacement for precision planetary gearbox,the equipment manufacturer can substantially reduce the price tag on 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 outcome of multiple worm wheels. It’s been used in computerized polishing mobile 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 best suited flank of worm shaft using different lead angle,leading to tooth thickness gradual switch,So that you can move worm shaft and modify backlash.

Low backlash Features :

— Worm gear gyration backlash can be adjusted to less than 1 arc.
— Reducer can be re-adjusted the gap after using .
— Input with coupling : reliable without backlash .
— Output working with conical clamping band couplings : reliable without backlash.

Applications :

Precision rotary motion

— Reducing the noises and vibration that’s caused by the strain change and the switch of cutting force.
— reducing the sound and impact that’s caused by the corotation and reverse.
— By cutting down worm abrasion.
— Increasing worm output response acceleration .

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 noise and the impact that’s caused by speed change.
— Reducing the worm abrasion that’s due to speed changes.
Low rotation Make choice :

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 that can be transmitted constantly through the output shaft, with the apparatus unit operated under a service factor fs = 1.
2、Required torque
Mr2 [Nm]
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.
3、Calculated torque
Mc2 [Nm]
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 relationship here after:
POWER
1、Rated input power
Pn1 [kW]
The parameter are available 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 could be calculated with the following formulas:
EFFICIENCY
Efficiency is a parameter that includes a major influence 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.
Remember that these values are just achieved following the unit has 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 not really significant factor for helical gears, it can be instead critical when choosing worm gearmotors functioning under intermittent duty.
SERVICE FACTOR [ fs ]
The service factor (fs ) depends on the operating conditions the gearbox is put through the parameters that require to be taken into consideration to select the most satisfactory servies factor effectively comprise:
1. type of load of the managed equipment : A – B – C
2. length of daily functioning time: hours/day(△)
3. start-up frequency: starts/hour (*)
TYPE OF LOAD: A good – uniform, fa≤0.3
B – moderate shocks, fa≤3
C – large shocks, fa≤10
fa=Je/Jm
–Je(kgm2) moment of the exterior inertia reduced at the drive shaft
–Jm(kgm2) moment of inertia of motor
–If fa>10 please contact our Technical Service
A good -Screw feeders for light materials, enthusiasts, assembly lines, conveyor belts for light materials, small mixers, lifts, cleaning machines, fillers, control machines.
B -Winding equipment, woodworking machine feeders, merchandise lifts, balancers,threading machines, moderate mixers, conveyor belts for major materials,winches, sliding doors, fertilizer scrapers, packing devices, concrete mixers, crane mechanisms, milling cutters, folding machines, equipment pumps.
C -Mixers for heavy materials, shears, presses, centrifuges, rotating supports, winches and lifts for heavy materials, grinding lathes, natural stone mills, bucket elevators, drilling equipment, 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 try to make it ideal for great radial and axial forces. PAR right position 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 those of a typical 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 help users to save the running price and improve the transmission proficiency. The input flange dimensions of PAR correct angle gearbox is available to be customized, accordingly, it is compatible with any brands of the servo motors, brushless DC motors and stepper motors.
