Low backlash right position servo worm reducer
high precision worm equipment is an ideal replacement 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 set up the servo motor get systems
Worm shaft found in series can be driven by one motor to accomplish synchronous productivity of multiple worm wheels. It has been used in automatic polishing mobile phone shell and other equipments
Servo worm gear products have three types : 45 – 50 – 55 – 63 – 75 – 90 ,with dual lead worm drive.Left and right flank of worm shaft using different lead angle,leading to tooth thickness gradual transformation,So that you can maneuver worm shaft and adapt backlash.
Low backlash Features :
— Worm gear gyration backlash can be adjusted to significantly less than 1 arc.
— Reducer can be re-adjusted the gap after using .
— Input with coupling : reliable without backlash .
— Output using conical clamping ring couplings : reliable without backlash.
Precision rotary motion
— Reducing the noise and vibration that is caused by the load change and the modification of cutting force.
— reducing the noises 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 line, cutting machine, transmission lines, etc.
— Indexing device,accurate reading mechanism require accurate movement occasions .
Speed changing situations
— Reducing the sound and the impact that’s due to speed change.
— Lowering the worm abrasion that is caused by speed changes.
Low rotation Make decision :
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.
1、Rated output torque
The torque which can be transmitted consistently through the output shaft, with the gear unit operated under a service factor fs = 1.
The torque demand predicated on application requirement. It is recommended to be add up to or less than torque Mn2 the gearbox under review is rated for.
Computational torque value to be used when choosing the gearbox. It is calculated considering the required torque Mr2 and service factor fs, as per the relationship here after:
1、Rated input power
The parameter can be found in the gearbox rating charts and represents the KW which can be safely transmitted to the gearbox, based on input speed n1 and service factor fs= 1.
2、Rated output power
This value is the power transmitted at gearbox output. it is usually calculated with the next formulas:
Efficiency is a good parameter which has a major impact on the sizing of certain applications, and basically will depend on gear pair designelements.
The mesh info table on page 9 shows dynamic efficiency (n1=1400)and static efficiency values.
Understand that these values are only achieved after the unit offers been run found in and is at the working temperature.
The dynamic efficiency is the relationship of power delivered at output shaft P2 to power applied at input shaft P1:
Efficiency obtained in start-up of the gearbox. Although that is generally certainly not significant aspect 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 subjected to the parameters that need to be taken into consideration to choose the most adequate servies factor correctly comprise:
1. type of load of the operated machine : A – B – C
2. length of daily operating time: hours/day(△)
3. start-up rate of recurrence: starts/hour (*)
TYPE OF LOAD: A – uniform, fa≤0.3
B – average shocks, fa≤3
C – serious shocks, fa≤10
–Je(kgm2) instant of the external inertia reduced at the travel shaft
–Jm(kgm2) instant of inertia of motor
–If fa>10 please contact our Technical Service
A -Screw feeders for light supplies, supporters, assembly lines, conveyor belts for light materials, small mixers, lifts, cleaning machines, fillers, control machines.
B -Winding devices, woodworking machine feeders, goods lifts, balancers,threading devices, channel mixers, conveyor belts for heavy materials,winches, sliding doorways, fertilizer scrapers, packing equipment, cement mixers, crane mechanisms, milling cutters, folding machines, equipment pumps.
C -Mixers for heavy supplies, shears, presses, centrifuges, rotating helps, winches and lifts for large materials, grinding lathes, stone mills, bucket elevators, drilling machines, hammer mills, cam presses, folding devices, turntables, tumbling barrels, vibrators, shredders.
series has a 90 degree source via helical bevel equipment,and its giant tapered roller bearings also get it ideal for superior radial and axial forces. PAR right angle reducer features an extremely short, light however rigid housing and total compatibility with standard electric motor adapters.PAR right angle planetary gearbox combines the benefits of a compact right angle gearbox and the ones of a typical planetary gearbox.Highest Accuracy, 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 motion control applications wherein the power flow has to be redirected. So that it can support users to save lots of the running price and enhance the transmission effectiveness. The input flange sizes of PAR proper angle gearbox is available to be customized, consequently, it is compatible with any makes of the servo stepper motors, brushless DC motors and motors.
