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 can 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 1 motor to attain synchronous output of multiple worm wheels. It has been used in automatic 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.Left and best flank of worm shaft working with different lead angle,causing 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 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 is caused by the load change and the switch of cutting force.
— reducing the noises and impact that is due to the corotation and reverse.
— By cutting down worm abrasion.
— Increasing worm output response velocity .

Precision Indexing device

— CNC machine, assembly collection, cutting machine, transmitting lines, etc.
— Indexing device,accurate reading mechanism require accurate movements occasions .

Speed changing situations

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

The following headings contain information on essential elements for selection and correct usage of gearbox.
For specific data on the gearbox collection,start to see the relevant chapters.
OUTPUT TORQUE
1、Rated output torque
Mn2 [Nm]
The torque that can be transmitted continually 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 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 choosing the gearbox. It is calculated considering the needed torque Mr2 and service issue fs, as per the partnership 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, based 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 can be calculated with the following formulas:
EFFICIENCY
Efficiency is a good parameter which has a major influence on the sizing of certain applications, and basically will depend 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 only achieved after 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 in start-up of the gearbox. Although that is generally not significant factor for helical gears, it might 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 put through the parameters that need to be taken into consideration to choose the most satisfactory servies factor appropriately 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 good – uniform, fa≤0.3
B – moderate shocks, fa≤3
C – large shocks, fa≤10
fa=Je/Jm
–Je(kgm2) instant of the external inertia reduced at the drive shaft
–Jm(kgm2) second of inertia of motor
–If fa>10 please contact our Technical Service
A -Screw feeders for light resources, supporters, assembly lines, conveyor belts for light materials, tiny mixers, lifts, cleaning equipment, fillers, control machines.
B -Winding equipment, woodworking machine feeders, things lifts, balancers,threading machines, moderate 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 elements, shears, presses, centrifuges, rotating works with, winches and lifts for hefty materials, grinding lathes, rock mills, bucket elevators, drilling machines, hammer mills, cam presses, folding machines, turntables, tumbling barrels, vibrators, shredders.
series includes a 90 degree suggestions via helical bevel gear,and its major tapered roller bearings also produce it ideal for great radial and axial forces. PAR right angle reducer features an extremely short, light yet rigid housing and total compatibility with standard engine adapters.PAR right angle planetary gearbox combines the benefits of a compact right angle gearbox and the ones of a conventional 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 must be redirected. So that it can support users to save the running expense and increase the transmission performance. The input flange sizes of PAR right angle gearbox is available to be customized, so, it is appropriate for any brands of the servo stepper motors, brushless DC motors and motors.
