Low backlash right position servo worm reducer
high precision worm gear is an ideal replacement for precision planetary gearbox,the equipment manufacturer may substantially reduce the price of using precision planetary gearbox
The designer’s ideal solution is to rotate 90 degrees to set up the servo motor travel systems
Worm shaft found in series could be driven by a single motor to attain synchronous productivity of multiple worm wheels. It has been used in programmed polishing cellular phone shell and other equipments
Servo worm gear systems have three types : 45 – 50 – 55 – 63 – 75 – 90 ,with dual lead worm drive.Left and ideal flank of worm shaft working with different lead angle,leading to tooth thickness gradual modification,To enable you to move worm shaft and adjust backlash.
Low backlash Features :
— Worm gear gyration backlash could be adjusted to significantly 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.

Low rotation Make decision :
The next headings contain information on essential components for selection and correct usage of gearbox.
For particular data on the gearbox collection,start to 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 recommended to be add up to or significantly less than torque Mn2 the gearbox under review is rated for.
3、Calculated torque
Mc2 [Nm]
Computational torque value to be utilized when selecting 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 can be found in the gearbox rating charts and represents the KW that can be safely transmitted to the gearbox, based 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 usually is calculated with the next formulas:
EFFICIENCY
Efficiency is a parameter which has a major impact on the sizing of certain applications, and basically is determined by 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 following the unit has been run in and reaches 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 that is generally certainly not significant point for helical gears, it can be instead critical when choosing worm gearmotors working under intermittent duty.
SERVICE FACTOR [ fs ]
The service factor (fs ) will depend on the operating conditions the gearbox is subjected to the parameters that require to be taken into consideration to choose the most satisfactory servies factor effectively comprise:
1. kind of load of the operated equipment : A – B – C
2. length of daily working time: hours/day(△)
3. start-up frequency: starts/hour (*)
TYPE OF LOAD: A good – uniform, fa≤0.3

series has a 90 degree suggestions via helical bevel gear,and its major tapered roller bearings also try to make it ideal for high 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 position gearbox and those of a typical planetary gearbox.Highest Accuracy, Highest Torque and Quiet 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 needs to be redirected. So it can support users to save lots of the running expense and enhance the transmission proficiency. The input flange measurements of PAR right angle gearbox is available to be customized, consequently, it is compatible with any makes of the servo brushless DC motors, motors and stepper motors.
