Double Row Ball Slewing Bearing—-Internal Gear

Characteristic of structure, performance and application

Double row ball slewing bearing has 3 seat ring, the steel ball and the spacing block can be directly arrange into the upper and lower races, 2 rows of upper and lower steel balls with different diameter are fitted according to the stress condition.

This kind of open assembly is very convenient, for the upper and lower bear raceway arc angles is 90°,which can bear large axial forces and tilting moment. When the radial force is greater than 0.1 times the axial force need to be specially designed the raceway.

Double row different ball slewing bearing’s axial and radial size are relatively large and CHINAMFG in structure, so it is specially suitable for the medium diameter tower cranes, truck mounted cranes etc. loading and unloading machinery.

What lubrication is required for internal gears?

Proper lubrication is essential for the optimal performance and longevity of internal gears. Here’s a detailed explanation of the lubrication requirements for internal gears:

  1. Lubricant Selection: The selection of lubricant for internal gears depends on several factors, including the application, operating conditions, gear material, speed, and load. Generally, high-quality gear oils or lubricants specifically designed for gears are recommended. These lubricants typically have additives to enhance their lubricating properties, reduce wear, and provide protection against corrosion and foaming.
  2. Viscosity: The viscosity of the lubricant is crucial for proper lubrication of internal gears. It determines the lubricant’s resistance to flow and its ability to form a durable film between the gear teeth. The viscosity should be chosen based on the gear’s speed and the operating temperature. Lower viscosity oils are suitable for high-speed applications, while higher viscosity oils provide better film thickness and load-carrying capacity for low-speed or heavy-duty applications.
  3. Application Method: The lubricant should be applied to the internal gears in a manner that ensures complete coverage and proper distribution. For small gears, oil baths or oil mist lubrication systems may be suitable. Larger gears may require automatic lubrication systems or manual application using brushes, oil guns, or centralized lubrication systems. The exact application method will depend on the specific gear system and the lubrication recommendations provided by the manufacturer.
  4. Lubrication Interval: Internal gears should be lubricated at regular intervals to maintain optimal performance. The lubrication interval depends on factors such as the gear design, operating conditions, and the lubricant used. Manufacturers often provide recommended lubrication intervals based on hours of operation or calendar time. Adhering to these intervals helps ensure that the lubricant remains effective and provides adequate protection and lubrication to the internal gears.
  5. Monitoring and Maintenance: Regular monitoring and maintenance of the lubrication system are important for internal gears. Periodically check the lubricant level, quality, and contamination. Conduct oil analysis or visual inspections to detect any signs of degradation or excessive wear. If necessary, replace the lubricant and clean the gear system before refilling with fresh lubricant. Proper maintenance practices help extend the life of the internal gears and prevent potential damage or failures.
  6. Environmental Considerations: Consider the operating environment when selecting lubricants for internal gears. Extreme temperatures, high humidity, dust, or chemical exposure can affect the lubricant’s performance. In such cases, specialized lubricants with enhanced resistance to temperature, water, oxidation, or contaminants may be required. Consult with lubricant suppliers or manufacturers for guidance on selecting lubricants suitable for specific environmental conditions.

In summary, selecting the appropriate lubrication for internal gears involves choosing a suitable lubricant based on factors such as application, viscosity, and operating conditions. Proper lubrication methods, regular maintenance, and monitoring the lubricant’s condition are essential for ensuring optimal performance and longevity of internal gears. By following recommended lubrication practices, you can minimize wear, reduce friction, and protect internal gears from damage in various applications and operating environments.
