Low backlash right angle servo worm reducer
high precision worm gear is an ideal substitute 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 end result of multiple worm tires. It’s been used in computerized polishing cellular phone shell and other equipments
Servo worm gear models have three types : 45 – 50 – 55 – 63 – 75 – 90 ,with dual business lead worm drive.Left and best suited flank of worm shaft working with different lead angle,causing tooth thickness gradual switch,To enable you to approach worm shaft and modify backlash.
Low backlash Features :
— Worm equipment gyration backlash can be adjusted to 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.
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 lowering worm abrasion.
— Increasing worm output response rate .
Precision Indexing device
— CNC machine, assembly series, cutting machine, transmitting lines, etc.
— Indexing device,accurate browsing mechanism require accurate movements occasions .
Speed changing situations
— Reducing the noise and the impact that is caused by speed change.
— Lessening 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 make use of gearbox.
For certain data on the gearbox array,start to see the relevant chapters.
1、Rated output torque
The torque that can be transmitted constantly through the output shaft, with the apparatus unit operated under a service factor fs = 1.
The torque demand based on application requirement. It is suggested to be equal to or significantly less than torque Mn2 the gearbox under study is rated for.
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:
1、Rated input power
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
This value is the power transmitted at gearbox output. it can be calculated with the following formulas:
Efficiency is a parameter that includes a major affect 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.
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 that is generally not significant point for helical gears, it can be instead critical when choosing worm gearmotors functioning 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 select the most enough servies factor appropriately 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 – weighty shocks, fa≤10
–Je(kgm2) point in time of the exterior 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 materials, followers, assembly lines, conveyor belts for light materials, tiny mixers, lifts, cleaning equipment, fillers, control machines.
B -Winding equipment, woodworking machine feeders, merchandise lifts, balancers,threading machines, moderate mixers, conveyor belts for large materials,winches, sliding doors, fertilizer scrapers, packing devices, concrete mixers, crane mechanisms, milling cutters, folding machines, equipment pumps.
C -Mixers for heavy products, shears, presses, centrifuges, rotating supports, winches and lifts for major 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 produce it ideal for large radial and axial forces. PAR right position reducer features an exceptionally short, light but 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 needs to be redirected. So it can help users to save the running cost and increase the transmission productivity. The input flange measurements of PAR correct angle gearbox is available to be customized, subsequently, it is compatible with any brands of the servo motors, brushless DC motors and stepper motors.
