Low backlash right angle servo worm reducer
high precision worm equipment is an ideal substitute for precision planetary gearbox,the gear manufacturer may substantially reduce the cost 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 could be driven by one motor to accomplish synchronous end result of multiple worm tires. 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.Still left and right flank of worm shaft using different lead angle,leading to tooth thickness gradual change,To enable you to approach worm shaft and change backlash.
Low backlash Features :
— Worm gear 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.
Precision rotary motion
— Reducing the noise and vibration that is caused by the strain change and the transformation of cutting force.
— reducing the noises and impact that’s due to the corotation and reverse.
— By lowering worm abrasion.
— Increasing worm output response rate .
Precision Indexing device
— CNC machine, assembly series, cutting machine, transmission lines, etc.
— Indexing device,accurate studying mechanism require accurate motion occasions .
Speed changing situations
— Reducing the noises and the impact that’s due to speed change.
— Cutting down the worm abrasion that is caused by speed changes.
Low rotation Make choice :
The following headings contain information on essential factors for selection and correct usage of gearbox.
For specific data on the gearbox array,start to see the relevant chapters.
1、Rated output torque
The torque that can be transmitted consistently through the output shaft, with the apparatus unit operated under something factor fs = 1.
The torque demand based on application requirement. It is recommended to be add up to or less than torque Mn2 the gearbox under research is rated for.
Computational torque value to be utilized when selecting the gearbox. It really is calculated considering the required torque Mr2 and service component fs, as per the relationship here after:
1、Rated input power
The parameter are available in the gearbox rating charts and represents the KW which can be safely transmitted to the gearbox, predicated on input speed n1 and service factor fs= 1.
2、Rated output power
This value is the power transmitted at gearbox output. it usually is calculated with the following formulas:
Efficiency is a good parameter which has 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.
Understand that these values are just achieved after the unit has been run in and reaches the working temperature.
The dynamic efficiency may be the relationship of power delivered at output shaft P2 to power applied at input shaft P1:
Efficiency obtained at start-up of the gearbox. Although this is generally certainly not significant factor for helical gears, it might 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 put through the parameters that require to be taken under consideration to choose the most enough servies factor effectively comprise:
1. kind of load of the operated 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 – average shocks, fa≤3
C – serious shocks, fa≤10
–Je(kgm2) instant of the exterior inertia reduced at the travel shaft
–Jm(kgm2) instant of inertia of motor
–If fa>10 please contact our Technical Service
A good -Screw feeders for light resources, fans, assembly lines, conveyor belts for light materials, tiny mixers, lifts, cleaning equipment, fillers, control machines.
B -Winding devices, woodworking machine feeders, products lifts, balancers,threading equipment, channel mixers, conveyor belts for major materials,winches, sliding doorways, fertilizer scrapers, packing machines, concrete mixers, crane mechanisms, milling cutters, folding machines, equipment pumps.
C -Mixers for heavy materials, shears, presses, centrifuges, rotating helps, winches and lifts for heavy materials, grinding lathes, rock mills, bucket elevators, drilling equipment, hammer mills, cam presses, folding machines, turntables, tumbling barrels, vibrators, shredders.
series includes a 90 degree source via helical bevel equipment,and its large tapered roller bearings also make it ideal for great radial and axial forces. PAR right angle reducer features an extremely short, light however rigid housing and complete compatibility with standard engine adapters.PAR right position planetary gearbox combines the advantages of a compact right angle gearbox and those of a typical 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 must be redirected. So that it can support users to save lots of the running cost and improve the transmission efficiency. The input flange dimensions of PAR right angle gearbox is open to be customized, subsequently, it is appropriate for any makes of the servo motors, stepper motors and brushless DC motors.
