Understanding Industrial Open Gear Lubrication and Its Limitations

Industrial open gear lubrication is a crucial aspect of machinery maintenance in various sectors, ensuring optimal performance and longevity of equipment. However, amidst its benefits, understanding the limitations of open gear lubrication is equally essential. In this blog, we’ll delve into the intricacies of industrial lubrication, shedding light on its importance, common practices, while also exploring the constraints and challenges it may encounter.

The Importance of Industrial Open Gear Lubrication:

Industrial operations often subject open gears to harsh conditions, including heavy loads, high temperatures, and exposure to contaminants. Adequate lubrication is indispensable to minimize friction, dissipate heat, and protect against wear and corrosion, thereby ensuring smooth operation and preventing premature failure of machinery.

Common Practices in Industrial Open Gear Lubrication:

Several lubrication methods and products are employed in industrial settings to lubricate open gears effectively: Grease Lubrication: Grease, with its ability to adhere to surfaces and provide long-lasting lubrication, is commonly used for open gears. Specialized formulations cater to specific operating conditions, ensuring optimal performance. Oil Lubrication: Oil lubrication involves the application of a continuous oil film to gear surfaces, offering excellent lubrication properties suitable for high-speed and heavy-duty applications. Various formulations, including mineral oils and synthetic blends, address diverse performance requirements. Solid Film Lubricants: Solid film lubricants, such as molybdenum disulfide or graphite, are applied as dry films to gear surfaces, providing low-friction coatings that mitigate wear and prevent metal-to-metal contact.

Limitations and Challenges of Industrial Open Gear Lubrication:

Despite its importance, industrial open gear lubrication faces several limitations and challenges: Ingress of Contaminants: Open gears are exposed to environmental contaminants such as dust, dirt, and water, which can compromise lubricant effectiveness and lead to increased wear and corrosion. High Operating Temperatures: In applications where, open gears are subjected to high temperatures, conventional lubricants may degrade or evaporate rapidly, necessitating frequent reapplication and maintenance. Maintenance Intervals: Industrial machinery often operates continuously, requiring regular lubrication maintenance. However, accessing and lubricating open gears in remote or inaccessible locations can be challenging, leading to extended downtime and increased maintenance costs. Compatibility Issues: Selecting the appropriate lubricant for specific gear materials and operating conditions is critical. Incompatibility between lubricants and gear materials can lead to reduced lubricant effectiveness, increased wear, and potential equipment damage.

Addressing Limitations and Enhancing Performance:

Despite these challenges, several strategies can mitigate the limitations of industrial open gear lubrication:
  1. Regular Inspection and Maintenance: Implementing routine inspections and maintenance schedules helps identify issues early and prevent equipment failure.
  2. Advanced Lubrication Technologies: Explore advanced lubrication solutions, such as high-performance greases and synthetic oils, designed to withstand extreme operating conditions and prolong equipment life.

Six Factors That Affect The Life Of A Lubricant

Six Factors That Affect The Life Of A Lubricant Lubricants play an essential role in a machine’s life and must carefully be monitored so its unexpected short life does not ruin your equipment. An old or dried-out lubricant can wreak havoc on your machines and lead to their downtime costing your industry millions of dollars. A lubricant that is kept in good condition with the right physical and chemical properties, optimal additives’ levels, and minimum contamination and wear can perform the following functions:
  • Minimize friction between metal parts of the machine
  • Decrease wear of machine parts
  • Regulate your machine’s operating temperatures
  • Minimize contamination
On the other hand, an old lubricant can cause permanent damage to your machine’s components as it will not regulate friction, and create contamination between the moving parts. For this reason, maximizing the life of a lubricant is critical. Below are the various factors that can make a lubricants’ life shorter. Preventing these factors can help prevent unscheduled downtimes and stoppages in your company’s production line.

Factors That Lead To Shorter Lubricant Service Life

In general, industrial lubricants lose their optimal functionality and efficiency after some time. However, this time is usually pre-determined by its manufacturer. If the lubricant goes bad before this time, it can lead to machine malfunctioning. Factors that can lead to shorter lubricant service life include:

Oxidation

This is a chemical reaction that occurs when the base oil comes in contact with free oxygen. It greatly reduces the lubricants life and its effectiveness as a lubricating agent. This is because oxidation leads to an increase in oil viscosity, resulting in varnish deposits. The accumulated sludge decreases machine efficiency by reducing heat transfer, blocking oil ways, promoting foam and emulsification, and ultimately resulting in seizures and machine breakdown.

Thermal Degradation

Machines that operate at high temperatures cause lubricating oils to undergo higher degradation rates in the absence of oxygen. This yields volatile gases and carbonaceous residues that contribute to heat build-up and machine damage. It is best to keep your machines at the lowest possible temperature to avoid this degradation and increase your lubricating oils’ service life.

Contamination

Oil contamination is the most common cause of oil degradation, which also facilitates other chemical reactions. These hinder basic machine processes such as aeration, foaming, air release, and demulsibility. Lubricating oil contaminants include water, airborne, dust particles, fluid soluble and insoluble materials, and the degraded oil components themselves.

Foaming

This constitutes the formation of froth/bubbles in the lubricants oil due to excess air that determines its poor quality. Air or oil foam can easily escape the reservoir and accumulate in the headspaces of gearboxes, crankcases, sumps, and other components with air spaces. It can also be ingested into the circulation pump and interfere with the gears and bearings’ effective lubrication.

Air Release

Air release is a necessary action that allows air to escape through bubbles in the oil. Poor quality lubricants are unable to perform this task effectively, and hence, contribute to oil foaming. Air release is greatly influenced by oil viscosity, temperature, and the presence of contaminants. Therefore, employing a good quality lubricant is an ideal solution to avoid this.

Demulsibility

This constitutes the lubricant oil’s ability to release water, which is imperative when the machinery is operating in a humid atmosphere. The oils’ inability to demulsify results in the corrosion of ferrous metals. A significant reduction in the fatigue life of ball bearings, roller bearings, and gears. It also hinders the removal of rust inhibitors, anti-wear, and lubricity additives from oils.

Maximize Your Lubricating Oil’s Service Life

The service life of lubricating oils is determined by their capability to avoid degradation. Good quality lubricating oils generally have an increased service life which you can further extend by operating the machinery at low temperatures, maintaining the oils and keeping it clean, preventing water ingress, and minimizing air contamination.
