Low backlash right angle servo worm reducer

Low backlash right angle servo worm reducer
high precision worm equipment is an ideal substitute for precision planetary gearbox,the gear manufacturer can substantially reduce the price tag on using precision planetary gearbox

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

Worm shaft found in series can be driven by a single motor to attain synchronous output of multiple worm wheels. It’s been used in automatic polishing cellular phone shell and other equipments
Servo worm gear units 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 change,So that you can move worm shaft and adjust backlash.

Low backlash Features :

— Worm equipment gyration backlash could 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 ring couplings : reliable without backlash.

Applications :

Precision rotary motion

— Reducing the sound and vibration that’s caused by the load change and the switch of cutting force.
— reducing the sound and impact that’s due to the corotation and reverse.
— By lessening worm abrasion.
— Increasing worm output response swiftness .

Precision Indexing device

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

Speed changing situations

— Reducing the noises and the impact that’s caused by speed change.
— Cutting down the worm abrasion that’s caused by speed changes.
Low rotation Make choice :

The next headings contain information on essential factors for selection and correct utilization of gearbox.
For particular data on the gearbox spectrum,see the relevant chapters.
OUTPUT TORQUE
1、Rated output torque
Mn2 [Nm]
The torque that can be transmitted consistently 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 equal 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 selecting the gearbox. It really is calculated considering the required torque Mr2 and service point fs, as per the relationship 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 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 just achieved after the unit offers been run found 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 in start-up of the gearbox. Although that is generally certainly not significant point for helical gears, it could be instead critical when choosing worm gearmotors functioning under intermittent duty.
SERVICE FACTOR [ fs ]
The service factor (fs ) depends upon the operating conditions the gearbox is put through the parameters that require to be taken into consideration to choose the most satisfactory servies factor effectively comprise:
1. type of load of the managed machine : A – B – C
2. length of daily working time: hours/day(△)
3. start-up frequency: starts/hour (*)
TYPE OF LOAD: A good – uniform, fa≤0.3
B – moderate shocks, fa≤3
C – heavy shocks, fa≤10
fa=Je/Jm
–Je(kgm2) point in time of the external inertia reduced at the drive shaft
–Jm(kgm2) point in time of inertia of motor
–If fa>10 please contact our Technical Service
A good -Screw feeders for light resources, lovers, assembly lines, conveyor belts for light materials, small mixers, lifts, cleaning devices, fillers, control machines.
B -Winding equipment, woodworking machine feeders, products lifts, balancers,threading devices, medium mixers, conveyor belts for large materials,winches, sliding doorways, fertilizer scrapers, packing machines, concrete mixers, crane mechanisms, milling cutters, folding machines, equipment pumps.
C -Mixers for heavy products, shears, presses, centrifuges, rotating supports, winches and lifts for heavy materials, grinding lathes, rock mills, bucket elevators, drilling machines, hammer mills, cam presses, folding devices, turntables, tumbling barrels, vibrators, shredders.
series includes a 90 degree suggestions via helical bevel equipment,and its large tapered roller bearings also make it ideal for large radial and axial forces. PAR right position reducer features an exceptionally short, light yet rigid housing and total compatibility with standard engine adapters.PAR right position planetary gearbox combines the advantages of a compact right angle gearbox and the ones of a typical 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 motion control applications wherein the power flow must be redirected. So it can support users to save the running price and improve the transmission proficiency. The input flange dimensions of PAR right angle gearbox is available to be customized, therefore, it is appropriate for any brands of the servo brushless DC motors, stepper motors and motors.
