LYHY Slewing Bearing Types
LYHY slewing bearings can be divided into the following types as per  their structures:
single row 4 point contact ball slewing bearing,
single row cross roller slewing bearing,
double row different ball diameter slewing bearing,
three row cylindrical roller slewing bearing and roller/ball combination slewing bearing.
And all these types of slewing bearings can be further divided into bearings without gears, bearings with external gears and bearings with internal gears.

Detailed description of these types slewing bearings

Single row 4 point contact ball slewing bearings
     This kind of slewing bearings can support high dynamic loads, transmitting axial and radial forces simultaneously as well as the resulting tilting moments. Applications of this kind of bearings are hoisting, mechanical handling and general mechanical engineering etc.
Single row cross roller slewing bearings
     This kind of bearings can support combinations of large radial force, medium axial force and tilting moment with small or zero clearance. Main applications of this kind of bearings are hoisting and mechanical handling and general mechanical engineering etc.
Double row different ball diameter slewing bearings
     This kind of bearings can support high static loads with simple structures. They are mainly used in situations with variation load position and direction and continuously rotating. Main applications of this kind of bearings are deck hoisting, mining and material handling etc.
Triple row cylindrical roller slewing bearings
     This kind of bearings has high load carrying capacity. Under same loads, this kind of bearings has much smaller diameters which can make the installation much compact, as different kinds of loads are supported by different races and rollers. Main applications of this kind of bearings are hoisting, mechanical handling, mining and materials handling, offshore technology and general mechanical engineering etc.
Roller/ball combination slewing bearings
     This kind of bearings can support high axial load and low tilting moments. Usually they are large diameter slewing bearings. Applications of this kind of bearings are mining and materials handling etc.

INSTALLATION OF CHINAMFG SLEWING BEARINGS

Preparation:
Make sure that the model is correct and slewing bearing isn’t damaged during transportation.
2.  Check the appearance and rotational state of the bearing, such as rotational precision clearance, rotating flexibility, seals position, lubrication grease etc.
3.  The installation datum plane and bracket installing plane should be clean, grease, burr, paint and other foreign body should be wiped off.

Installation:

1. The screws in the installing plane should be fit with the mounting holes in the slewing bearing
2.  The slewing bearing has a soft zone marked with an “s” on the upper surface, when installing the bearing, it is important to ensure that this area is placed in a non-load or infrequent load zone.
3.  When the bearing is placed on the supporting frame work it is important to check the interface between these 2 surfaces. This check should be carried out with the insertion of feel gauges between the 2 surfaces. If a gap should exist then it is recommended to plane/resurface the effective area so as to remove the gap.
4.  Install slewing bearing with high strength screws, and choose appropriate strength bolts. All bolts are required to be tightened evenly. The sequence of this tightening process is shown in Pic. Welding of bearing is not allowed, in the event of welding any adjacent parts, heat transfer shall be avoided so as to cause the bearing to become deformed or change the hardness.
5.  After installation, the bearing should be rotated to check for smooth operation and any emission of unusual noise. If either of the aforementioned are noted, then the bearing should be adjusted to eliminate them. The teeth of the largest run-out are coated with green paint.

What lubrication is required for ring gears?

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

  • Type of Lubricant: The type of lubricant used for ring gears depends on various factors, including the application, operating conditions, and gear design. Common lubricants for ring gears include gear oils, grease, and synthetic lubricants. Gear oils are specifically formulated for gear systems and provide excellent lubrication and protection against wear. Grease is often used in applications where the gear system operates at lower speeds or requires higher viscosity lubrication. Synthetic lubricants offer enhanced performance, durability, and resistance to extreme temperatures and loads.
  • Lubricant Properties: The lubricant chosen for ring gears should possess certain properties to ensure effective lubrication. These properties include high film strength, good thermal stability, resistance to oxidation, and anti-wear characteristics. The lubricant should also be compatible with the materials used in the ring gear system to prevent damage or degradation of the gear surfaces.
  • Viscosity: Viscosity is an important consideration when selecting lubrication for ring gears. Viscosity refers to the thickness or resistance to flow of the lubricant. It is crucial to choose a lubricant with the appropriate viscosity to ensure proper lubrication film formation between the gear teeth. If the lubricant’s viscosity is too low, it may not provide sufficient lubrication, leading to increased wear. Conversely, if the viscosity is too high, it may cause excessive friction and energy loss. The recommended viscosity range is typically specified by the gear manufacturer or industry standards.
  • Lubrication Method: The lubrication method for ring gears can vary depending on the specific application and gear system design. For enclosed gear systems, such as gearboxes or sealed housings, lubrication is typically performed by filling the housing with the recommended lubricant to the appropriate level. In open gear systems, such as large industrial gears, lubricant application methods may include spray systems, drip lubrication, or circulation systems. The lubrication method should ensure sufficient coverage and distribution of the lubricant to all gear surfaces.
  • Lubrication Frequency: Regular lubrication maintenance is crucial to keep ring gears properly lubricated. The frequency of lubrication depends on the operating conditions, gear system design, and the lubricant used. It is important to follow the manufacturer’s recommendations or industry standards regarding lubrication intervals. Regular inspections should also be conducted to monitor the lubricant condition, check for contamination, and replenish or replace the lubricant as needed.
  • Environmental Considerations: Environmental factors, such as temperature, moisture, and contamination, can affect the performance of the lubricant and the ring gears. It is important to consider these factors when selecting the lubricant. Extreme temperatures may require lubricants with enhanced thermal stability, while exposure to moisture or harsh contaminants may necessitate lubricants with better resistance to corrosion or water washout.

To ensure the proper lubrication of ring gears, it is advisable to consult the gear manufacturer’s recommendations and guidelines. They can provide specific information regarding the suitable lubricant type, viscosity range, lubrication method, and maintenance practices for the particular ring gear system.

Can you provide examples of machinery that use ring gears?

Machinery in various industries utilize ring gears for different applications. Here are some examples of machinery that commonly use ring gears:

  • Automotive Transmissions: Ring gears are an integral part of automotive transmissions. They are used in automatic transmissions, manual transmissions, and dual-clutch transmissions. Ring gears help transmit power from the engine to the wheels by engaging with the pinion gear or other associated gears.
  • Industrial Gearboxes: Ring gears are extensively used in industrial gearboxes, which are employed in a wide range of applications. Gearboxes in industries such as manufacturing, mining, construction, and energy generation use ring gears to transmit power and control rotational speed. They provide torque multiplication and speed reduction or increase as required by the specific machinery.
  • Wind Turbines: Ring gears are crucial components in wind turbines. They are used in the main gearbox to convert the rotational motion of the wind turbine blades into electrical power. The ring gear connects the rotor shaft to the generator, enabling the transmission and conversion of the mechanical energy into electrical energy.
  • Rotary Tables: Rotary tables are used in machining operations to provide precise positioning and rotational movement. They are commonly found in milling machines, drilling machines, and machining centers. Ring gears are employed in the rotary tables to enable smooth and accurate rotation, allowing for precise machining and indexing of workpieces.
  • Printing Presses: Printing presses, particularly those used for high-speed commercial printing, often incorporate ring gears. Ring gears help drive the paper feed mechanisms and synchronize the movement of various components, ensuring precise control and alignment during the printing process.
  • Excavators and Earthmoving Equipment: Large construction machinery, such as excavators and earthmoving equipment, rely on ring gears for their hydraulic systems. Ring gears enable the rotation and control of the excavator’s superstructure, including the boom, arm, and bucket. They provide the necessary power and torque for efficient digging, lifting, and material handling.

How do ring gears differ from other types of gears?

Ring gears, also known as annular gears or internal gears, possess distinct characteristics that set them apart from other types of gears. Here’s a detailed explanation of how ring gears differ from other gears:

  • Tooth Configuration: The most significant difference between ring gears and other gears is their tooth configuration. In a ring gear, the teeth are located on the inside circumference of a circular ring, whereas in other gears such as spur gears, helical gears, and bevel gears, the teeth are present on the outer surface of the gear. This internal tooth arrangement makes ring gears unique and allows them to mesh with pinion gears or other external gears.
  • Gear Assembly: The assembly of ring gears differs from other gears. In most cases, ring gears are used in combination with pinion gears or other external gears. The pinion gear meshes with the teeth on the inside of the ring gear. This gear set configuration enables the transmission of rotational motion and torque.
  • Load Distribution: Ring gears distribute the load over a larger area compared to other types of gears. The load is spread across the internal teeth of the ring gear, resulting in improved load-carrying capacity and enhanced gear durability. This load distribution characteristic makes ring gears suitable for applications that involve high loads or continuous operation.
  • Gear Ratio: Ring gears offer specific advantages in terms of gear ratios. They are commonly used in applications where high gear ratios are required. The gear ratio is determined by the number of teeth on the ring gear compared to the number of teeth on the mating gear (such as a pinion gear). The internal tooth configuration of the ring gear allows for larger gear diameters, enabling higher gear ratios to be achieved.
  • Space Utilization: Ring gears provide a compact design compared to some other types of gears. The internal tooth arrangement allows for a more space-efficient gear assembly. This compactness is advantageous in applications where space is limited or where a high gear ratio needs to be achieved within a confined area.
  • Applications: Ring gears are commonly used in automotive transmissions, differential systems, planetary gear systems, industrial machinery, robotics, power generation equipment, and heavy machinery. Their unique characteristics make them suitable for applications that require precise motion control, load distribution, and high gear ratios.

It’s important to note that the specific design, tooth profile, material selection, and manufacturing techniques may vary for different types of gears, including ring gears. Each type of gear is designed to meet specific application requirements, operating conditions, and performance needs.
