Product Description

78mm ZDR Series High Precision Planetary Gearbox For Servo Motor
 
Product Description

ZDR series planetary gearbox has adopted helical gear design, so the meshing of gears can be smoother. This series has a double-supported and sealed structure, easier to install for customers. It is widely used in linear manipulators, packaging machinery, assembly lines and etc. The maximum backlash of the ZDR series is less than 5 arc.min and the reduction ratio covers 3~81.


The Product Advantages of Planetary Gearbox:

1.Flexible structure design, in line with various working conditions.
2.Ring gear processing technology: Using internal gear slotting machine and hobbing machine; the precision of ring gear after processing can reach GB7.
3.Hardened gear secondary scraping technology: secondary high-speed dry cutting of gear eliminates gear deformation caused by heat treatment. Gear accuracy can reach GB6.
4.Reliable backlash testing.

Note1) The moment of input shaft conversion is only gained from the reducer, so it does not include moment of inertia of the motor.
Note2) The max. input speed is 5000rpm. Usually set to 3000rpm or less.
Note3) The permissble radial load is indicated on the center of the output shaft.
Note4) All values are within the range corresponding to helical gear.

Mechanism & Parts:
ZD High Precision 78mm ZDR Series Planetary Gearbox for Servo Motor
Double support mechanism

1.The planetary gear is placed in the middle of the output shaft.
2.The output shaft bearing is placed at both ends of the planetary gear.
3.Separate sun gear and coupling.











Compact output shaft mechanism

It adopts the design of output shaft integrated system, compact structure, high rigidity, and it can withstand large impact. Place the input coupling and the sun gear at the center of the output shaft to improve the concentricity of the components, thereby effectively controlling the gear clearance and improving the backlash of the whole gearbox.

Full needle structure

The inner bearing of the planetary gear adopts a full-needle design, the inner hole is made by a grinding process, the surface hardness is HRC60, and the cylindricity is less than 0.003mm.

















Ring gear structure

The integral structure of the ring gear and the output flange improves its rigidity and reduces misassembly.
