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 .
— Output using conical clamping ring couplings : reliable without backlash.
Applications :

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.
OUTPUT TORQUE
1、Rated output torque
Mn2 [Nm]
The torque that can be transmitted constantly through the output shaft, with the apparatus unit operated under a service factor fs = 1.
2、Required torque
Mr2 [Nm]
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.
3、Calculated torque
Mc2 [Nm]
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:
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, predicated on input speed n1 and service factor fs= 1.
2、Rated output power
Pn2 [kW]
This value is the power transmitted at gearbox output. it could be calculated with the next formulas:
EFFICIENCY
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.
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 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
fa=Je/Jm
–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.
