Applications Of Roller Bearing In Heavy Machinery

Roller Bearing
The roller bearing is used in the mobilization of machinery to reduce friction between moving parts. The different types of roller bearings are used in heavy-duty machinery that supports radial, axial and thrust loads. This blog discusses various applications where roller bearings are used in heavy machinery.  The bearings are made to support complex mechanical systems and their vitality can be observed in their application in a multitude of machinery. Be it automobiles, aeronautics, railways, earthmoving or agriculture, the roller bearings can be used perfectly to match the needs of different heavy-duty applications.  While referring particularly to a roller bearing, they are designed in such a way to support performance in those applications where there are large axial and radial loads. The Roller Bearings consist of the outer ring, inner ring, and a window cage which works as a holder for the rollers.

Design of Roller Bearing – Supporting Heavy Machinery

Roller Bearing helps in support the large radial and axial loads in heavy-duty machinery. This works in one direction to guide the axial loads while complimenting bearings are also used simultaneously to support the load in other directions. These types of bearings can be widely used in those conditions where the temperature may vary between -30 degrees celsius to 120 degrees Celsius.

Applications of Roller Bearings in Heavy Machinery

There can be varied types of Heavy Machinery that might require heavy-duty applications. Here are some of the applications of roller bearings in heavy machinery:
  • Wind Turbine Generators for Energy Generation – Wind Turbine generators are usually installed in high-altitude areas which require a reliable bearing solution that can operate within the high-performance wind turbines in high-speed winds. In such conditions, the tapered roller bearing and spherical roller bearings can be installed in the main shaft of the wind turbine that receives the force and can pass on the rotation to the generator.
  • Use of Roller Bearing in Agriculture Machinery – The agriculture industry also demands heavy-duty machinery as it has to deal with heavy-duty applications on a day-to-day basis. While these applications range in a multitude of high-performance tasks, the bearings must be reliable and long-lasting as they have to be used in heavy dirt and mud conditions which might also impact the bearing life. The roller bearings are one such perfect solution that can be used in varied tasks which might require heavy radial or axial loads and they can get the work done with ease. The common type of bearing used in the agriculture industry is a tapered roller bearing.
  • Construction and Heavy Machinery – The construction industry requires varied earth-moving equipment for a high range of heavy-duty tasks. While there can be varied challenges while dealing with the applications of construction, the bearings are usually exposed to excessive working conditions as machines have to be deployed for high-performance tasks. In order to meet this demand, there is a need for different types of roller bearings such as spherical roller bearings, tapered roller bearings, cylindrical roller bearings, etc. which are designed to deliver the desired performance.
  • Use of Roller Bearings in Railways – The railways are considered one of the most reliable modes of transport worldwide. While there are different systems, trains, and tracks connected over wide networks, heavy-duty machines are used to facilitate day-to-day operations. The bearings in the railway industry are used in traction motors, drive units, wheel axles, etc. While the bearings have to work in extreme conditions of carrying heavy loads and adapting to high vibrations in drive units, varied roller bearings like tapered and spherical roller bearings are also widely used to support the mechanical system. Since the railway network is now moving towards high-speed trains, the roller bearings are also designed especially for double helical gears which can work for a longer duration without the need for lubrication.
  • Use of Spherical Roller Bearings in Marine Propulsion  – Marine propulsion can be referred to as a thrust system that is used to move a boat or a giant ship. While this is also considered in the category of heavy-duty application, the diesel engine of the ship is linked to the propeller which facilitates the movement through a complex system. Here, roller bearings can be used within the shaft or different mechanical systems as there can be conditions where the bearing has to adjust to radial or axial load while also complying with the scope of heavy misalignment. These kinds of bearings are designed to handle one-directional axial load and radial load at the same time while allowing shaft misalignment.
Conclusion While heavy-duty applications use bearings within the machinery, the complex working conditions can make bearings tough to work as desired.

Everything You Need To Know About Heat Treatment Operations

Heat treatment services
The process of heat treatment operations is quite common in the metallurgy industry. Since different metals and materials need to be required in certain properties, this process helps in making metals hard or soft depending upon the varied requirements. Now coming into the scenario for bearings, the bearings come in contact with hard metals which increases the risk of wear and tear resulting in breakdown or decrease in the service life of bearings. To harden the bearing and make it capable of bearing the thrust, weight and friction of other metals, the hardening process is followed through heat treatment to make it apt for all conditions and applications. The bearings are used in various types of machinery and mechanical systems to reduce friction. As they need to be perfect in shape, size, precision, and quality, the heat treatment operation makes it worthwhile to be used in any application under the toughest conditions.

How Heat Treatment Operation is Performed

The heat treatment operation involves various processes which are aimed towards achieving certain results. Here are some of the points which precisely explain it:
  1. Heating material under tight controls and specified temperature.
  2. Holding temperature as per the specific time duration to achieve desired results.
  3. Performing slow cool to fast cool while following varied methods.
These different conditions determine the changes in metal structures as it results in modification of properties due to exposure to high temperature. Some of the properties that material may develop after heat treatment are hardness and toughness.

Hardening Bearing to Improve its Strength – Why is it used?

The bearings should have desired strength to achieve optimum performance without any failures. To make it work in extreme conditions, there is a need to harden its surface to reduce friction while coming in constant communication with surfaces of other materials. To understand it better, machines may contain various components and bearings are fit in between them to reduce friction. To make the bearing perform in an optimum manner, it is crucial that it withstand a hardened surface.

Types of Hardening Process for Bearings in Heat Treatment Operations

The hardening process is quite crucial for bearings. Here are different types of hardening processes that are performed in heat treatment operations:
  1. Case Hardening
The Case Hardening process is used to toughen the exterior of the bearing making it apt for shock bearing and wear tear applications. In such a case, the inner part of the bearing will become softer than the exterior. This can also be done through the process of carburizing where the material is heated with carbon-bearing material like charcoal or carbon monoxide making the surface tougher and stronger resulting in resistance to wear and tear.
  1. Induction Hardening
This type of hardening generates similar results as carburizing but here the electric wire coil is used to achieve desired results and hardening of the material. The electric wire coil works as an inductor here and parts of the bearing which need to be inducted are placed in the copper coil to heat it above the transformation temperature through an alternating current. This process can be specific to certain applications and is mostly used for hardening the raceway of a ball bearing.
  1. Through Hardening
Through hardening is used to make the tensile strength and hardness of bearing strong which also uses a rapid quenching to change the structure of metal making it tougher. This is the type of operation which makes it tough to the core and performed in such conditions where uniform strength, wear-resistance and hardness is required. Conclusion Heat treatment is a very crucial operation for bearings as it needs to be hardened as per the requirement and application to adjust to varied needs. Since bearings are used in different types of machinery in railways, aeroplanes, automobiles, etc. they need to be built in such a way that it possesses the utmost strength and durability to bear different conditions.
