Item Description

ZD 115mm ZB Sequence Large Precision and Small Backlash Planetary Gearbox for Servo Motor

Solution Description

The large-precision planetary gearbox adopts helical equipment design, and is employed in various handle transmission fields with servo motors, this kind of as precision equipment instruments, laser chopping equipment, battery processing products, and so on. It has the positive aspects of input and output built-in composition, large torque and large precision. The backlash of the ZB collection is considerably less than 3 arc.min and the reduction ratio covers 3~one hundred.

The Product Advantages of Planetary Gearbox:
1.Flexible composition design, in line with a variety of working conditions.
2.Ring equipment processing technology: Making use of inside gear slotting equipment and hobbing equipment the precision of ring equipment right after processing can attain GB7.
3.Hardened equipment secondary scraping engineering: secondary higher-speed dry slicing of gear removes equipment deformation brought on by warmth treatment. Gear precision can achieve GB6.
four.Reputable backlash testing.

Double assistance system
1.The planetary gear is put in the middle of the output shaft.
two.The output shaft bearing is positioned at equally finishes of the planetary equipment.
three.The input shaft is positioned inside the output shaft.
four.built-in CZPT solar equipment.

Compact output shaft system
It adopts the design of output shaft integrated technique, compact construction, substantial rigidity, and it can stand up to large effect. Place the enter CZPT and the solar gear at the center of the output shaft to boost the concentricity of the comp1nts, therefore properly managing the gear clearance and strengthening the backlash of the entire gearbox.


Full needle composition
The inner bearing of the planetary equipment adopts a total-needle layout, the internal gap is made by a grinding process, the surface area hardness is HRC60, and the cylindricity is less than .003mm.

Ring equipment structure
The integral construction of the ring gear and the output flange increases its rigidity and reduces misassembly.


Sector Application Case

Q: What’re your major products?
A: We at the moment generate Brushed DC Motors, Brushed DC Equipment Motors, Planetary DC Gear Motors, Brushless DC Motors, AC Motors, Higher Precision Planetary Gearbox and Precision Cycloidal Gearbox and so on.. You can check out the specifications for previously mentioned motors on our internet site and you can email us to recommend necessary motors for every your specification as well.

Q: How to decide on a appropriate motor or gearbox?
A:If you have motor pictures or drawings to present us, or you have thorough technical specs, this sort of as, voltage, velocity, torque, motor dimension, working manner of the motor, needed lifetime and sounds stage and so forth, remember to do not wait to enable us know, then we can advocate suitable motor per your request accordingly.

Q: Do you have a personalized services for your standard motors or gearboxes?

A: Generally speaking, our typical regular product will want 15-30days, a little bit for a longer time for tailored products. But we are extremely adaptable on the direct time, it will rely on the distinct orders.


AC motors are also various from DC motors due to the fact most AC motors do not contain brushes. This implies that routine maintenance and parts replacement wants for AC motors are likely to be significantly decreased, with most consumers normally expecting a lengthier typical lifespan. Unlike DC motors, the output pace of a lot of varieties of AC motors is frequently determined by inverter control – once more, we’ll briefly outline a range of likely variants on the basic AC motor model.
AC motors vary from a lot of other kinds of motors, particularly some of the far more acquainted DC (immediate recent) motors, by numerous critical standards. The most fundamental of these is the truth that an AC motor depends totally on the alternating existing around its circuit to generate powerful mechanical energy. We will examine this exclusive process in much more depth in the subsequent sections of this guide.
