China manufacturer High Precision and Small Backlash 115mm Zb Series Planetary Gearbox for Servo Motor high quality

Solution Description

115mm ZB Series Substantial Precision and Little Backlash Planetary Gearbox

Product Description

The large-precision planetary gearbox adopts helical equipment design and style, and is employed in a variety of manage transmission fields with servo motors, this sort of as precision machine equipment, laser cutting products, battery processing equipment, etc. It has the advantages of enter and output built-in composition, huge torque and large precision. The backlash of the ZB sequence is considerably less than 3 arc.min and the reduction ratio handles 3~a hundred.

The Product Advantages of Planetary Gearbox:
1.Versatile composition layout, in line with various working circumstances.
2.Ring equipment processing technology: Using interior gear slotting machine and hobbing device the precision of ring equipment soon after processing can attain GB7.
3.Hardened equipment secondary scraping technology: secondary large-speed dry chopping of equipment eliminates equipment deformation caused by warmth treatment. Equipment precision can reach GB6.
four.CZPT backlash testing.

Double assist mechanism
1.The planetary gear is put in the center of the output shaft.
2.The output shaft bearing is put at each finishes of the planetary gear.
three.The enter shaft is placed within the output shaft.
4.integrated coupling sun equipment.

Compact output shaft system
It adopts the style of output shaft integrated program, compact composition, large rigidity, and it can endure big impact. Area the input coupling and the sun gear at the heart of the output shaft to enhance the concentricity of the components, thereby properly controlling the equipment clearance and enhancing the backlash of the entire gearbox.


Entire needle composition
The interior bearing of the planetary equipment adopts a total-needle style, the inner hole is created by a grinding procedure, the floor hardness is HRC60, and the cylindricity is significantly less than .003mm.

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

An AC motor is a variety of motor that utilizes the phenomenon of electromagnetic induction. AC electricity drives the motor. It is a existing that periodically reverses course and changes its magnitude of the recent over time. This recent is the reverse of a direct present or “DC” which flows in only one route. AC motors can supply a reasonably effective way to produce mechanical energy from a basic electrical input signal.
