Reliability and maintenance engineers can improve uptime and save money on both long-term maintenance and downtime costs by properly diagnosing and correcting bearing vibration issues when they exceed their acceptable limits. This requires inspecting the housing as well as the liner for wear, and replacing them as a pair when the housing is worn, so that wear-in between the mating surfaces can occur.
Implementing a predictive maintenance (PM) program can be tough. Despite its proven success, many companies have been operating the same way for over 50 years and donâ™t know where to start. Understanding where to start and where to focus is critical. The intention of this article is to give insight to start and sustain an effective program using todayâ™s technology and devices.
This is an article about motors - preventive motor maintenance, actually. And something else - mechatronics. In today's high-tech manufacturing and industrial use environments, it is near impossible to talk about equally complex motor maintenance and repair-or-replace protocols without it.
Health monitoring or condition monitoring has been used for many years on machines and in plants where the cost of an outage is high. It allows failures to be anticipated and maintenance or repairs to be scheduled for the least loss of production, as well as avoiding unnecessary periodic maintenance.
A man stands at a proverbial pulpit, dressed like a company executive but speaking like a fire and brimstone southern preacher.
Chain and sprocket drives of one form or another have been driving machines and conveying materials for over a thousand years. The chain manufacturing industry has developed numerous types and sizes of drive chains. Although it is a mature form of power transmission, there are still many industrial applications for which drive chain is suited. It is economical, resistant to shock loads, easy to install, has the ability to transmit high torque, operates in hostile environments, and is efficient. Chain and sprocket drives are highly engineered and manufactured within close tolerances.
Few would now argue that what some may have perceived just a few years ago as âœChicken Littleâ stories regarding the depletion of this countryâ™s skilled manufacturing workforce are now in fact firmly based in stark reality.
Is industrial maintenance another lost art, or is there hope that we can train the next generation of maintenance professionals?
Regardless of where you do business, when discussing, analyzing or worrying about âœThe Economyâ these days, youâ™re not thinking Main Street - youâ™re thinking global. With that stipulation, it is also accepted wisdom that quality products and sharp pencils are not enough to be and remain competitive. Accordingly, everyone is looking for an edge, an advantage, in order to beat back - or at least keep up with - the competition.
Increasing pressure on many fronts is compelling mine operators to thoroughly examine every phase of their operations. Fluctuating demand that whipsaws mineral prices, government-imposed environmental regulations and rising operating costs related to maintenance downtime all pose serious challenges for the mining sector. Add pressure from customers and stakeholders for more sustainable operations as well as union demands for higher wages, and you have a scenario that requires mine operators to exercise every possible option to achieve more efficient operations.

Special tools and bearing modifications can make removal and installation much safer and easier for plant technicians.
The use of motor current signature analysis (MCSA) for motor fault detection â” such as a broken rotor bar â” is now well established. However, detection of mechanical faults related to the driven system remains a more challenging task. Recently there has been a growing interest for detection of gear faults by MCSA. Advantages and drawbacks of these MCSA-type techniques are presented and discussed on a few industrial cases.
Downtime, downtime, downtime. When it's planned, it's bearable. When it's not, it's not. To maintain machinery, planned downtime is necessary. To fix broken equipment, unplanned downtime is excruciating, especially when your factory is running closer and closer to full capacity.
How to determine if your facility needs an overhaul. Includes a Q&A with experts from Stober Drives.
Rolling-element bearings are high-precision components that need to be stored and handled carefully to perform as designed. Proper storage and handling of a bearing before, during and after installation is important because once debris enters a bearing, it reduces the life.
Even when the critical components of industrial power transmission gear drive systems are properly designed, specified and manufactured consistent with application requirements, performance problems can develop over time and failure may follow.
Good machinery can last a lifetime. But, replacement parts for older equipment may be near impossible to find. So, what do you do when you're looking to replace hard-to-find bearings and related parts for older machines?
Motor Operation Gets Big Boost from Smart Technology (Here's How to Take Advantage)
This three-part series on motor management best practices focuses on the importance of instituting a motor management plan as a necessity in effectively administering the electric motors in a facility. The goal of a motor management plan is to take advantage of opportunities for energy savings and increased productivity using energy efficient, reliable motors such as NEMA Premium efficiency motors, herein referred to as âœpremium efficiencyâ motors.
Lubrication management should be standard operating procedure at any manufacturing facility. Vital to both operational and maintenance personnel, a strong, coherent and specific lubrication program will have lasting results in machine efficiency and maintenance. Of course, even those with the best intentions canâ™t always keep up with the challenges presented day-to-day on the manufacturing floor. Thankfully, PTE is here to help with eight steps to selecting, storing, analyzing and managing your lubrication requirements.
Valves help control temperature, pressure and viscosity for alcohol fermentation.
While some organizations focus on real-world analytics and data collection for predictive maintenance, simulation tools and virtual prototyping can be another solution for motor efficiency.
Sustainability is becoming one of the most important aspects within the power transmission business. Users demand low-maintenance drive systems with as little disruption as possible, and expect lifetimes of more than 10,000 hours. Approximately 40 percent of long-term gearbox leakages can be traced back to poor interaction between the radial shaft seal (RSS) and the lubricant. Thus, it becomes essential to analyze the tribological system as a whole, which includes the gear oil, seal grease (if required), elastomer material and design, and the shaft.
Rolling element or sleeve bearings often are required to operate under extreme conditions. In these instances, it is more important than ever to follow proper lubrication selection and maintenance procedures to maximize effective life and efficient performance.
If you are involved in the acquisition of technology (whether your direct role is machine design, maintenance, purchasing or management), trade shows still provide one of the best ways to evaluate options, learn about the latest technology and find solutions to problems.
For a maintenance crew, it is important to know which bearings need re-lubrication and make sure they are lubricating those bearings. The bearings can be lubricated manually or by automatic lubrication systems. This article will review each method and discover its pros and cons.
Condition-based maintenance requires detailed state knowledge, often acquired by means of sensors.
Many industrial facilities with air-cooled heat exchangers (ACHE) and cooling towers often have older units installed. Depending on the age, repairs, and maintenance done over the years it may have had an impact on performance. Upon conducting site inspections of the equipment, it is sometimes found that ACHE or cooling tower components have degraded. This can result in a system that is not very energy-efficient and delivers substandard cooling performance.
When rolling element or sleeve bearings operate under extreme conditions, itâ™s more important than ever to follow proper lubrication selection and maintenance procedures to maximize eff ective life and effi cient performance.
The U.S. Space Shuttle fleet was originally intended to have a life of 100 flights for each vehicle, lasting over a 10-year period, with minimal scheduled maintenance or inspection. The first space shuttle flight was that of the Space Shuttle Columbia (OV-102), launched April 12, 1981. The disaster that destroyed Columbia occurred on its 28th flight, February 1, 2003, nearly 22 years after its first launch.
Robotics and other advanced automation technology systems are viewed as a looming threat to some in the plant maintenance field. Although there is a constant battle for some workers to remain useful while machines are continuously fulfilling more roles on the plant floor, there are those who in turn have found a better use of their newly freed time.
Can direct drive technology improve your bottom line? Manufacturers relying upon drive systems in their production process have long sought ways to improve gearbox efficiency. While a gearbox-driven system has been the mainstay for manufacturers, it has also been, among other things, the source of frequent breakdowns, expensive line stoppages and increasingly costly maintenance.
When a bearing is damaged, it is often removed from service and replaced before it reaches its full, useful and economical life. Advancements in bearing design, materials, bearing maintenance and repair methods have greatly improved the potential for and popularity of bearing repair as an effective way to extend the life of the bearing.
Manufacturing employees have always kept their eyes on the robotic systems that continue to pop up in assembly lines and industrial workspaces. These metallic, low-maintenance robotic employees donâ™t waste time with smoke breaks or catching up on episodes of Lost. They tend to stick to the task at hand with little argument or attitude, giving human counterparts a bad name when they gripe about factory temperatures or lack of a decent dental plan.
Upgrading to gearboxes with helical gearing can save on energy, maintenance and landfill space.
