FAQs

• Before installation, check whether the gearbox and other components are in good condition, including inspecting gears, bearings, seals, etc., for any damage or abnormalities.
• During installation, adjust parameters such as axial, vertical, and parallel alignment according to the gearbox's design requirements to ensure precise positioning without affecting its operation.
• Pay attention to the correct positioning of the gearbox and connecting components to avoid improper installation that could lead to gearbox damage.

• Regularly replace the lubricating oil, selecting appropriate lubricants according to the gearbox's specifications to maintain good lubrication, reducing wear and damage.
  
• Periodically inspect the gearbox's seals and bearings to ensure their proper functioning, preventing oil leakage and abnormal noises.
  
• Regularly monitor the gearbox's operating conditions and temperature, promptly addressing any abnormalities.

The lifespan and service life of a gearbox depend on several factors, including the operating environment, working conditions, lubrication status, load, and frequency of use.

If the gearbox operates in harsh environments, under severe working conditions, experiences heavy loads, and is frequently used, its lifespan and service life may be relatively shorter.

Generally, with proper maintenance and normal usage, a gearbox's lifespan and service life can reach several years or even decades.

The selection of appropriate gearbox oil is crucial in ensuring stable operation and extending the lifespan of the gearbox. Here are the considerations and guidelines for choosing gearbox oil:

• Select the appropriate oil based on usage environment and requirements:
  Choose the type and specifications of gearbox oil according to factors such as operating temperature, load, and rotational speed.

• High-pressure resistance:
  Gearbox oil should have excellent high-pressure resistance to prevent excessive pressure during gearbox operation, thereby protecting the gears from damage. 
• Antioxidant properties:
  Gearbox oil should have good antioxidant properties to prevent oil degradation due to oxidation during usage, which can affect the gearbox's operational efficiency and lifespan.
• Excellent lubrication performance:
  Gearbox oil should provide effective lubrication to reduce friction between gears, bearings, and other components, preventing wear and corrosion.
• Pay attention to oil change intervals:
  Regularly change the gearbox oil according to the usage conditions to avoid using expired or contaminated oil, which could impact performance.

• Ensure oil quality:
  When purchasing gearbox oil, ensure that the quality is guaranteed, preferably choosing products from reputable brands with good reviews and quality assurances.

In summary, selecting the right gearbox oil is one of the crucial factors for the gearbox's proper functioning. It is essential to pay attention to oil selection, change intervals, and quality to ensure the gearbox's long-term stable operation.

Important Items:

1. Room temperature at 10℃~40℃.
2. When room temperature is at extreme high (or extreme low), please contact the company to determine the suitable oil viscosity.
3. Oil temperature an handle sudden temperature change up to 120℃，Common oil temperature usage is at around 80℃. If used at 100℃, oil changing should be frequent.
4. If there is any further question, please contact our design department.

Lubricating Oil Viscosity Grade Chart (Used to indicate the viscosity grades of different oils)

ISO VG (International Organization for Standardization Viscosity Grade) is a designation used to indicate the viscosity grade of oils, represented in cSt (centistokes) at 40°C. The Viscosity Designation Table helps users choose suitable lubricating oils to meet the specific requirements of their lubrication systems.

For any other installation or operational inquiries, please refer to the support service and download Gearbox Operator's Manual.

In summary:

Viton oil seals have excellent oil resistance, high-temperature resistance, and ozone resistance but are more expensive.

NBR oil seals have better low-temperature resistance and abrasion resistance but have poorer high-temperature and solvent resistance, and they are more cost-effective.

Therefore, the choice of oil seal material should be based on specific application needs.

Please note that the choice between plate heat exchanger and shell and tube heat exchanger should consider specific application requirements and priorities.

Gear heat treatment is a crucial step in the gear manufacturing process, as it plays a vital role in enhancing the physical and operational characteristics of gears, thereby improving their longevity and efficiency.

The key aspects of its significance are as follows:

1. Improved Hardness and Strength:
   Heat treatment allows precise control of the heating, soaking, and cooling processes, adjusting the gear's microstructure and hardness to enhance its strength and wear resistance.
2. Enhanced Toughness:
   Heat treatment improves the gear's microstructure, resulting in improved toughness and resistance to fatigue, thereby enhancing its ability to withstand bending and torsional stresses.
3. Reduced Deformation and Cracking:
   Heat treatment eliminates internal stresses generated during gear processing, reducing the risk of deformation and cracking.
4. Enhanced Wear and Corrosion Resistance:
   Heat treatment forms a hardened surface layer with high wear and corrosion resistance, thereby improving the gear's durability against wear and corrosive elements.

In conclusion, gear heat treatment is an indispensable step in gear manufacturing, serving to improve the physical and operational characteristics of gears, leading to increased longevity and efficiency. Strict control over the heat treatment process and parameters ensures stable and reliable results.
