Low backlash right position 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 set up the servo motor travel systems
Worm shaft in series can be driven by one motor to attain synchronous productivity of multiple worm wheels. It’s been used in automatic polishing cellular phone shell and other equipments
Servo worm gear units have three types : 45 – 50 – 55 – 63 – 75 – 90 ,with dual lead worm drive.Still left and ideal flank of worm shaft using different lead angle,causing tooth thickness gradual modification,To be able to move worm shaft and modify backlash.

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 assortment,start to see the relevant chapters.
OUTPUT TORQUE
1、Rated output torque
Mn2 [Nm]
The torque which can be transmitted continuously 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 significantly less than torque Mn2 the gearbox under analysis is rated for.
3、Calculated torque
Mc2 [Nm]
Computational torque value to be utilized when choosing the gearbox. It is calculated considering the expected torque Mr2 and service issue 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 which 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 following formulas:
EFFICIENCY
Efficiency is a good parameter which has a major effect on the sizing of certain applications, and basically depends 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 just achieved following the unit features 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 at start-up of the gearbox. Although this is generally not really significant component for helical gears, it can 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 put through the parameters that require to be taken into consideration to select the most satisfactory servies factor correctly comprise:
1. kind of load of the operated machine : A – B – C
