Low backlash right angle servo worm reducer
high precision worm gear is an ideal replacement for precision planetary gearbox,the equipment manufacturer can substantially reduce the expense of using precision planetary gearbox
The designer’s ideal solution is to rotate 90 degrees to install the servo motor get systems
Worm shaft in series can be driven by one motor to achieve synchronous outcome of multiple worm tires. It’s been used in automated polishing cellular 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 working with different lead angle,causing tooth thickness gradual modification,To be able to move worm shaft and adapt backlash.
Low backlash Features :
— Worm equipment 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 .

Precision rotary motion
— Reducing the noises and vibration that is caused by the strain change and the modification of cutting force.
— reducing the noise and impact that is due to the corotation and reverse.
— By reducing worm abrasion.
— Increasing worm output response rate .
Precision Indexing device
— CNC machine, assembly line, cutting machine, transmitting lines, etc.
— Indexing device,accurate browsing mechanism require accurate motion occasions .
Speed changing situations
— Reducing the noises and the impact that is caused by speed change.
— Lowering the worm abrasion that is caused by speed changes.
Low rotation Make choice :
The following headings contain information on essential components for selection and correct utilization of gearbox.
For particular data on the gearbox spectrum,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 predicated on application requirement. It is suggested to be add up to or less than torque Mn2 the gearbox under research is rated for.
Computational torque value to be utilized when choosing the gearbox. It really 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 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 could be calculated with the next formulas:
Efficiency is a parameter which has a major impact 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 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 at start-up of the gearbox. Although this is generally not significant aspect for helical gears, it could be instead critical when selecting worm gearmotors operating under intermittent duty.
SERVICE FACTOR [ fs ]
The service factor (fs ) is determined by the operating conditions the gearbox is put through the parameters that need to be taken under consideration to choose the most sufficient 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 – uniform, fa≤0.3
B – moderate shocks, fa≤3
C – large shocks, fa≤10
–Je(kgm2) instant of the exterior inertia reduced at the travel shaft
–Jm(kgm2) minute of inertia of motor
–If fa>10 please contact our Technical Service
A good -Screw feeders for light resources, admirers, assembly lines, conveyor belts for light materials, small mixers, lifts, cleaning machines, fillers, control machines.
B -Winding equipment, woodworking machine feeders, merchandise lifts, balancers,threading equipment, moderate mixers, conveyor belts for major materials,winches, sliding doorways, fertilizer scrapers, packing equipment, 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, rock mills, bucket elevators, drilling devices, hammer mills, cam presses, folding devices, turntables, tumbling barrels, vibrators, shredders.
series has a 90 degree suggestions via helical bevel gear,and its large tapered roller bearings also help to make it ideal for superior 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 angle planetary gearbox combines the features of a compact right angle gearbox and the ones of a typical planetary gearbox.Highest Accuracy, 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 movement control applications wherein the power flow has to be redirected. So that it can support users to save lots of the running cost and improve the transmission performance. The input flange measurements of PAR right angle gearbox is available to be customized, therefore, it is compatible with any brands of the servo motors, brushless DC motors and stepper motors.
