Low backlash right angle servo worm reducer

Low backlash right position servo worm reducer
high precision worm equipment is an ideal substitute for precision planetary gearbox,the equipment manufacturer may substantially reduce the expense of using precision planetary gearbox

The designer’s ideal solution is to rotate 90 degrees to set up the servo motor travel systems

Worm shaft in series could be driven by one motor to achieve synchronous result of multiple worm tires. It has been used in automatic 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,causing tooth thickness gradual modification,To be able to maneuver worm shaft and adapt backlash.

Low backlash Features :

— Worm equipment gyration backlash can be adjusted to significantly less than 1 arc.
— Reducer could 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 noise and vibration that is caused by the strain change and the change of cutting force.
— reducing the noise and impact that’s caused by 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 studying mechanism require accurate movements occasions .

Speed changing situations

— Reducing the sound and the impact that’s due to speed change.
— Reducing 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 utilization of gearbox.
For particular data on the gearbox range,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 gear unit operated under something factor fs = 1.
2、Required torque
Mr2 [Nm]
The torque demand based on application requirement. It is suggested to be add up to or less than torque Mn2 the gearbox under study is rated for.
3、Calculated torque
Mc2 [Nm]
Computational torque value to be used when choosing the gearbox. It really is calculated considering the expected 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, 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 might be calculated with the following formulas:
EFFICIENCY
Efficiency is a good parameter that includes a major affect 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 features been run found in and is at the working temperature.
1、Dynamic efficiency
[ηd]
The dynamic efficiency may be 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 this is generally not significant component for helical gears, it can be instead critical when choosing worm gearmotors working under intermittent duty.
SERVICE FACTOR [ fs ]
The service factor (fs ) is determined by the operating conditions the gearbox is subjected to the parameters that need to be taken under consideration to select the most satisfactory servies factor appropriately comprise:
1. kind of load of the operated equipment : A – B – C
2. length of daily functioning time: hours/day(△)
3. start-up regularity: starts/hour (*)
TYPE OF LOAD: A – uniform, fa≤0.3
B – moderate shocks, fa≤3
C – large shocks, fa≤10
fa=Je/Jm
–Je(kgm2) point in time of the external inertia reduced at the drive shaft
–Jm(kgm2) moment 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, little mixers, lifts, cleaning machines, fillers, control machines.
B -Winding products, woodworking machine feeders, merchandise lifts, balancers,threading equipment, moderate mixers, conveyor belts for heavy materials,winches, sliding doorways, fertilizer scrapers, packing machines, concrete mixers, crane mechanisms, milling cutters, folding machines, equipment pumps.
C -Mixers for heavy supplies, shears, presses, centrifuges, rotating works with, winches and lifts for heavy materials, grinding lathes, stone mills, bucket elevators, drilling machines, hammer mills, cam presses, folding machines, turntables, tumbling barrels, vibrators, shredders.
series includes a 90 degree type via helical bevel equipment,and its major tapered roller bearings also try to make it ideal for great radial and axial forces. PAR right angle reducer features an extremely short, light yet rigid housing and full compatibility with standard engine adapters.PAR right position planetary gearbox combines the benefits of a compact right angle gearbox and the ones of a conventional planetary gearbox.Highest Precision, Highest Torque and Calm Operation are provided by 100% optimized Helical Gearing.

With the compact structure but powerful design, PAR right angle planetary gearbox is ideal option for movement control applications wherein the power flow should be redirected. So it can support users to save lots of the running cost and enhance the transmission productivity. The input flange dimensions of PAR correct angle gearbox is available to be customized, so, it is appropriate for any brands of the servo brushless DC motors, motors and stepper motors.
