Low backlash right position servo worm reducer
high precision worm gear is an ideal substitute for precision planetary gearbox,the gear 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 travel systems
Worm shaft in series can be driven by 1 motor to attain synchronous end result of multiple worm wheels. It has been used in automatic polishing mobile 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 best suited flank of worm shaft using different lead angle,leading to tooth thickness gradual modification,So that you can move worm shaft and adjust 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 using conical clamping ring couplings : reliable without backlash.
Applications :
Precision rotary motion
— Reducing the noise and vibration that is caused by the load change and the change of cutting force.
— reducing the noise and impact that’s caused by the corotation and reverse.
— By reducing worm abrasion.
— Increasing worm output response quickness .
Precision Indexing device
— CNC machine, assembly series, cutting machine, transmission lines, etc.
— Indexing device,accurate studying mechanism require accurate activity occasions .
Speed changing situations
— Reducing the noise and the impact that’s caused by speed change.
— Lessening the worm abrasion that’s caused by speed changes.
Low rotation Make choice :
The following headings contain information on essential elements for selection and correct utilization of gearbox.
For specific data on the gearbox assortment,see the relevant chapters.
OUTPUT TORQUE
1、Rated output torque
Mn2 [Nm]
The torque which can be transmitted consistently through the output shaft, with the apparatus unit operated under something factor fs = 1.
2、Required torque
Mr2 [Nm]
The torque demand predicated on application requirement. It is recommended to be add up to or significantly less than torque Mn2 the gearbox under analysis is rated for.
3、Calculated torque
Mc2 [Nm]
Computational torque value to be used when choosing the gearbox. It really is calculated considering the expected torque Mr2 and service element fs, as per the partnership here after:
POWER
1、Rated input power
Pn1 [kW]
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
Pn2 [kW]
This value is the power transmitted at gearbox output. it might be calculated with the following formulas:
EFFICIENCY
Efficiency is a parameter that includes 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 only achieved after the unit offers been run 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 in start-up of the gearbox. Although this is generally certainly not significant component for helical gears, it might be instead critical when selecting worm gearmotors functioning under intermittent duty.
SERVICE FACTOR [ fs ]
The service factor (fs ) depends upon the operating conditions the gearbox is subjected to the parameters that require to be taken under consideration to select the most sufficient servies factor correctly comprise:
1. kind of load of the managed equipment : A – B – C
2. length of daily functioning time: hours/day(△)
3. start-up rate of recurrence: starts/hour (*)
TYPE OF LOAD: A – uniform, fa≤0.3
B – moderate shocks, fa≤3
C – heavy shocks, fa≤10
fa=Je/Jm
–Je(kgm2) instant of the exterior inertia reduced at the drive shaft
–Jm(kgm2) second of inertia of motor
–If fa>10 please contact our Technical Service
A -Screw feeders for light resources, supporters, assembly lines, conveyor belts for light materials, small mixers, lifts, cleaning devices, fillers, control machines.
B -Winding units, woodworking machine feeders, things lifts, balancers,threading equipment, 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 supports, winches and lifts for major materials, grinding lathes, natural stone mills, bucket elevators, drilling devices, hammer mills, cam presses, folding equipment, turntables, tumbling barrels, vibrators, shredders.
series has a 90 degree input via helical bevel equipment,and its major tapered roller bearings also try to make it ideal for superior radial 
and axial forces. PAR right position reducer features an exceptionally short, light yet rigid housing and complete compatibility with standard engine 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 movement control applications wherein the power flow should be redirected. So that it can support users to save the running price and increase the transmission proficiency. The input flange measurements of PAR correct angle gearbox is open to be customized, consequently, it is compatible with any makes of the servo brushless DC motors, motors and stepper motors.
