This series is used to match the press mill with asterism wheel, presser, and square shaft. The gearbox is a reducer with central drive, two output ratings and three parallel axial cylindrical gears. It features with compactness, high precision, low noise, high capacity, high efficiency, and long service life. Special floating coupling has to be used on the input side when necessary.
There are two sectional concepts. One is asymmetrical section rectangular to axis of output shaft, the sectional face is located in the upper part for the rectangular installed casting. Which is favorable for sealing of contact faces; the other one is sectioned at middle line.
Cylindrical gear is designed of single helical tooth, the conical gear is of spiry tooth. All the gears are made of alloy steel, grinding the teeth after case-hardening. Shafts are made of quality quenched and tempered steel, bearing are all roller bearings.

This GS series, speed increaser gearbox, is a kind of multifunctional gearbox. It can be uesd both for military and civil. Besides, this equipment is widely used by turbine, gas turbine power generation and the like.
Product parameters:
1. High RPM: the max. speed of the series gearbox can reach 8000r/min;
the max. peripheral speed reaches 160m/s.
2. High specification: max center distance is 1000mm and max power reaches 96000kW.
3. High precision: the gear precision reaches ISO4-6 grade and the gear dynamic balancing precision reaches ISO0.4-1.6.
4. High-tech: the product is designed by 3-D CAD; the finite element analysis is conducted; modification during gear grinding against thermal deformation on gear profile is applied; the tooth root is strengthened by shot peening; soft ware of calculating sliding bearing capacity and analyzing rotor system dynamics are used.
5. High reliability: lifetime of the gearbox is designed to ten years.
H-type compressor gearboxes are mainly used in chemical industry for getting oxygen, nitrogen and carbon dioxide by compressing air. The gearbox is designed and inspected per API613-2003.
Specifications
1.Stable running & low noise
2.High efficiency
3. Low noise
4. Light weight
5. Small size and little vibration
Main Features
1. Single input shaft and multi-output shafts are parallel arranged in the gearbox
2. Helical gears and thrust disc are adopted; gears are carburized and quenched before tooth grinding. Gears, shafts and
3. Housings are with balanced intensity design. FEA is done for critical components.
4. Proper tooth modification (cover elastic and thermal deformation) increases transmission efficiency, operation stability and reduces noise level of the gearbox.
5. Defect detections are implemented for gears and thrust discs at both raw and finished conditions.
6. Advanced hydrodynamic sliding bearings are used to ensure better operational stability.
7. Non-contacting mechanical sealing system is adopted to avoid leakage and renewal.
8. High rotating speed, big transmission ratio at single stage, large axial force from exterior, small size, light weight, high efficiency, low noise level and vibration, high stability and long service life are the major advantages of this series gearbox.
Main Parameters
The Max. Power: 9800KW
The Rotary Speed: 30000rpm
Product features:
1. High load capacity: carbonization, quenching, and grounding processed.
2. Small size, light weight: compared with soft tooth face and medium hard tooth face reducer, QY series of same capacity are much lighter.
3. High efficiency, low noise, and low vibration: grounding improves precision. Tip relief enhances its overall efficiency and reduces noise and vibration.
4. Multiple driving stage: widen the center distance, decrease unit height, this meets the requirements of crane structure.
5. Convenient mounting: three-point type reducer convenient mounting type: horizontal, vertical and even of some angle.
6. both CW and CCW rotary direction.
Main technical parameters
1. Maximum circumferential velocity: 20m/s
2. Maximum spindle speed: 1500r/min
3. Maximum transmission ratio: 400
